Intrusion Detection and Prevention Systems

Intrusion Detection Systems (IDS) vs Intrusion Prevention Systems (IPS): What’s What?

An Intrusion Detection System (IDS) and Intrusion Prevention System (IPS) have very similar acronyms by which they are commonly known, yet they perform very different tasks within the network security process. So what exactly do they do, how do they do it, and does your organization need either, neither, or both as part of your overall security posture?

Intrusion Detection System

Definitions are important in the security world—you have to understand what you are dealing with before you can accurately determine if it's a good fit for the needs of your organization. So what exactly is an Intrusion Detection System (IDS)? Simply put, an IDS can be either a hardware device or software application that monitors network traffic, incoming and outbound, for any malicious activity or security policy violation. Think of it as an intruder alarm, sounding an alert if it spots any activity that could lead to network and data compromise. It does this by inspecting the packets that flow across the network in order to detect known indicators of compromise and traffic patterns that suggest suspicious activity. In other words, an IDS is a passive system used to bring real-time visibility into potential network compromises.

How the IDS achieves this will depend on the type of system being deployed. They can be either network based, or host based. Network-based Intrusion Detection Systems (NIDS) will have sensors strategically placed within the network itself, sometimes at multiple locations, to monitor the most traffic without creating performance bottlenecks. Host-based Intrusion Detection Systems (HIDS) do things differently, and are run on specific hosts or devices, only monitoring the traffic associated with them. Either type can take different approaches to detecting suspicious traffic. Some might use signature detection, comparing packets against a database of known threats. Some might use an anomaly-based approach, comparing traffic patterns against an established network “normality” baseline. Some will combine both methods. All are known for generating false positives, at least initially. The IDS will need configuration to fine-tune it for the particular “norms” of your network and the devices attached to it.

Intrusion Prevention System

An Intrusion Prevention System (IPS) is like an IDS on steroids. Not only can it detect the same kind of malicious activity and policy violation that an IDS does, but as the name suggests it can execute a real-time response to stop an immediate threat to your network. Like an IDS, the IPS can be NIPS-based with sensors at various points of the network or HIPS-based with sensors on the host to monitor individual devices. Unlike the IDS, an IPS has the ability to configure policy-based rules and actions to be executed when any anomaly is detected. Think of it as being an active defense system, tailored to best suit your business needs in terms of security posture. 

Although often considered a firewall, this is an erroneous assumption about an IPS. If anything, an IPS is a firewall in reverse: The firewall applies a rule-set to allow traffic to flow; an IPS applies a rule-set to deny and drop traffic. That said, there are Unified Threat Management (UTM) devices, which do both and therefore act as firewall and IPS simultaneously. These might appear to offer the best of both worlds, in that they can actively allow “good” traffic while also blocking known “bad” traffic.  However, UTMs can be hard to manage optimally, and tend not to enable the same granularity of control over IPS protections as a stand-alone IPS can offer.

Which do you need?

Now you know the differences between an IDS and IPS, which does your organization need as part of its network security implementation? Truth be told, the stand-alone IDS has pretty much been replaced by the IPS as far as the IT security industry is concerned. That's not to say intrusion detection is a busted flush, but rather that detection has to be accompanied by prevention technologies in today’s increasingly frantic threat climate. For most organizations, the notion of administering an IDS as a separate solution alongside other reactive solutions makes little sense. What makes more sense is to adopt a layered approach to detection and prevention while working with a managed service provider (MSP) able to make better sense of the complexities of the security function and respond to alerts more effectively.

.MDB File Format in Access Software

.MDB File Format in Access Software

MDB is the default file format used in Microsoft Office Access, up to Access 2003. In the 2007 and 2010 versions, however, Access uses the newer ACCDB file format as the default.

The file extension for the MDB file format is .mdb.

Data, in the context of databases, refers to all the single items that are stored in a database, either individually or as a set. Data in a database is primarily stored in database tables, which are organized into columns that dictate the data types stored therein.

A database (DB), in the most general sense, is an organized collection of data. More specifically, a database is an electronic system that allows data to be easily accessed, manipulated and updated.

In other words, a database is used by an organization as a method of storing, managing and retrieving information. Modern databases are managed using a database management system (DBMS).

Microsoft Office Access is Microsoft’s answer to providing a small database engine. It enables users with little knowledge of database administration to quickly set up their own database. The following versions of Access use the MDB file format as default: Access 95, 97, 2000 and 2003.

In 2007, Microsoft introduced a new file format (the ACCDB file format) with the 2007 version of Access. Access 2010 continues to use the same format. However, the 2007 and 2010 versions are also compatible with the older MDB format.

Earlier Access control Systems manufacturer uses this extension to design Access Management software. Like Syris use cardV3.mdb for master database.

MS Access software allows users to create, manage and query a database using its GUI controls and features, without having to write programming queries.

Role of IT in Access Control System

Role of IT in Access Control System

It is a fact that IT is becoming more involved in the physical security world. In a small minority of companies, these two departments are actually merging, although this is a mammoth task fraught with problems, not only in terms of technology, but primarily in terms of culture.

In the access control world, one could say it’s normal for IT to be involved in networking (assuming the access systems make use of the corporate network and/or the IP protocol), but the scope of IT has slowly been creeping into more of the access control functions. In smaller companies, for example, it’s not unusual for the service provider responsible for the company’s IT to also take the responsibilities of physical security.

So how far has IT made inroads into the access control world in general? HID Global broadcast arrange a webinar in October 2018 in which it revealed some new research into the increasing role IT departments and personnel are playing in the physical access control world. The webinar was hosted by HID Global’s Brandon Arcement and Matt Winn. After discussing the findings of the research, they went on to advise physical security operators as to how they can embrace their IT colleagues further, with the goal of improving the holistic security posture of their organisations.

The survey was conducted by The 05 Group, sponsored by HID and was completed in March 2018. As the title of this article notes, the research found that IT departments are now more involved than ever in organisations’ physical access control decisions and implementation, and that trend is set to increase.

The 05 Group surveyed 1 576 individuals from more than a dozen industries, including education (19%), information (16%), government (11%), manufacturing (8%), health services (8%), and security, professional and business services (8%). Of the respondents, 35% were IT managers, 26% were IT directors, 13% were IT staff, 8% were CIO/CTO, and 3% were VPs of technology. The survey also spanned companies of different sizes, with 24% having less than 100 employees, 22% 101-500 employees, 11% have 501-1000 employees, 17% have 1001-5000, 6% have 5001-9999, and 6% have 10 000-24 999 employees. The results therefore cover a broad spectrum of companies and industries.

 The numbers tell a story

The research offers a significant amount of data about the role of IT in access control, however the webinar brought out a few pertinent facts (a link to the white paper written by HID from the research is at the end of this article). When asking the organisations being surveyed “Who is primarily responsible for physical access control in your organisation”, the responses were as follows:

• 29% said both IT and physical security.

• 26% said IT only.

• 25% said facility management handles the job.

• 12% said physical security only.

• 8% said the property management company was tasked with access control.

With a quarter of the respondents already saying IT is responsible for access control, and a further 29% saying it is shared between the two departments, it’s clear that the divide between IT and physical security is rapidly vanishing – and in some cases, altogether gone. And this is a trend that will continue; in organisations where IT is not involved in access control, 36% of the respondents said it will be within the next five years.

For those organisations where access control responsibilities are shared, 47% of the respondents report it had been shared within the past five years. Similarly, where IT owns the responsibility, 42% of the companies say they were given this task within the last five years. Once again we see that IT/physical security convergence in the access world is an expanding reality.

We mentioned IT’s influence in access control above in terms of the networking of access systems, however, this is an old function. The webinar showed that both IT professionals as well as physical security professionals see IT being involved in all areas of access control. When it comes to physical security professionals:

• 66% of physical security professionals see IT involved in influencing the decision-making process.

• 48% see IT’s involvement in integrating access and other systems.

• 37% see IT involved in implementation.

• 22% see IT involved in managing the systems.

From the other side of the table, IT professionals have a similar view:

• 76% expect to influence decision making.

• 72% will be involved in integration.

• 59% will be involved in implementation.

• 39% expect to be involved in managing systems.

Not all wine and roses

Of course, as these different cultures work together, there are bound to be some issues. It is in the field of integration where IT sees problems. Half of the IT people surveyed have issues with the lack of integration of access systems with other IT systems. This is an area in which the access control industry could make significant changes in the short-term to ensure their software and hardware can be more easily integrated with existing business management and security systems.

When it comes to new access control systems, the IT school has a few things it wants to see on the vendors’ to-do list. They want improved ease of use (71%), the ability to support or add new technologies (68%), mobile access (59%), and integration with existing security platforms (54%).

It’s also clear from the survey that IT is not all that comfortable with access control technology. Areas such as credential management, decision making with respect to access control systems, how system components work and also individual features within access systems can cause a bit of nervousness among the IT folk. These are areas in which physical security professionals can make their mark, as they are more skilled in dealing with these issues as well as others unique to their industry. 

Helping IT in access

The driver behind this convergence is not a technical issue, but is itself a convergence of a number of separate drivers. HID notes the primary drivers are:

• Converged threats that impact both physical and logical infrastructure. If you have a physical vulnerability it puts your logical systems at risk, and vice versa.

• Proliferation of networked devices in the age of IoT (the Internet of Things) which all require both physical and logical security. Interestingly, the webinar held its own real-time survey of the attendees and this topic was selected as having the biggest impact on access control’s shift to IT with half of the audience selecting it.

• Compliance to new regulations, which again rely on both sides of the table.

• Budget consolidation, which we are all suffering through.

• A shift in reporting structures as executives try to get a handle on the seemingly endless threats companies face on all fronts.

When it comes to the role of physical security professionals and how they can assist in the convergence between the two sides and help improve organisational security, 80% of the respondents said they play a role in establishing best practices, while 50% see physical security having a role in preventing unauthorised access in general, and 49% say they can help in achieving compliance. In order to streamline collaboration, the HID webinar suggests, among other issues, that both sides need to work on aligning project priorities and determining responsibilities, and balancing the technical acumen of IT when it comes to access products and management. 

A converged example

The webinar went on to provide an example of how the two divisions could work together in an access control installation. When it comes to the physical access control host, HID advises organisations to integrate physical access control systems (PACS) with an IT source of identity such as LDAP. Furthermore, administrators should ensure there is a set policy around regular software updates and patches, while they should also take advantage of IT’s experience (and equipment) to ensure high availability.

When it comes to the controller, HID advises organisations to settle some of the issues raised above by requiring an open controller platform that can be integrated with other technologies and other vendors’ products. Preventing vendor lock-in is a costly lesson IT departments have learned. It also suggests considering an ‘IP-at-the-door’ topology, keeping controller firmware updated to the latest versions, using strong passwords and encrypting communication between controllers and hosts (and using OSDP – Open Supervised Device Protocol – for encrypted reader communications).

Another strong warning was to take care when selecting access credentials as many of the card and fob technologies available are easy to replicate, making it simple for the wrong people to easily gain access. There are secure card technologies out there and these should be used as a standard. A business benefit of these more advanced credentials is that they can also be used for additional business functions, such as secure printing, vending machines and network logon.

The webinar presenters also touched on the benefits of using users’ mobile devices as credential holders. These can offer higher levels of authentication, easier administration and more user convenience that does not come at the expense of the company’s security.

Whether you are on the IT or physical security side, the most important part of the research (depending on your biases) can be seen in the answer to the question “Do you believe that increased collaboration between physical security and IT can improve the overall security of your organisation?” An overwhelming 95% of all the respondents said “yes”.

While the full convergence of physical and logical security is still some way off, people in the access control sector obviously understand that IT and physical security working together is critical to develop a successful security defence strategy for their organisations. In the access control industry this may be easier to achieve, but as noted in the introduction, it is often a question of culture (or ego, to be blunt) that prevents collaboration and results in organisations being vulnerable to the ever-increasing threats they face from well-organised criminal syndicates, as well as unhappy teenagers with too much time on their hands.

CCTV HDD Bad Sector Repair Steps

CCTV HDD Bad Sector Repair Steps

If you are a Electronic Security Technician you must know how to repair DVR / NVR HDD Bad Sector.

Some Common surveillance Hard Drive Problems.

Three Methods:Windows XP, Windows 7, Windows 8

Bad sectors are sections of your computer’s hard drive that have been damaged, and have lost the ability to save and store your data. If your computer makes grinding noises when using the hard drive, that’s a good sign that your hard drive has bad sectors. When you repair a bad sector, your computer will replace the bad sectors with good sectors and ignore the bad sectors. The methods for repairing bad sectors are different, depending on what version of Windows you’re using. (This is all falls under common hard drive problems )

The larger your hard drive, the more sectors there are to check, and the longer this process will take. Start this process when you won’t need your computer for a while, such as overnight.

Windows XP

Close all of your open programs and files. Windows XP can’t scan or fix a bad sector if that sector is being used by an open program or file.

Windows XP uses a system utility called Chkdsk to scan for and fix bad sectors.

Open My Computer. Double-click My Computer to open it.

Choose a hard drive to check for bad sectors. In the Explorer window, in the sidebar, right-click the hard drive you’d like to check for bad sectors, and then click Properties.

The C: drive is often the hard drive.

In the Properties window, click the Tools tab.

In the Error-checking section, click Check Now.

Choose the Check Disk options you’d like to use. In the Check Disk dialog box, you can have Check Disk fix file system errors it finds and recover bad sectors.

If you’d only like to scan for and fix bad hard drive sectors, make sure that Automatically fix file system errors is unchecked.

Click Start. Windows will start checking your hard drive for bad sectors and will fix any that it finds.

If you have any open files or programs at this point, you’ll get an error message asking if you’d like to schedule the disk check when you restart your computer. If you click Yes, it will restart your computer and perform the disk check.

Review the Chkdsk report. When it’s done.

(This is all falls under common hard drive problems )

2 of 3: Windows 7

Close all of your open programs and files. Windows 7 can’t scan or fix a bad sector if that sector is being used by an open program or file.

Open Computer. Click Start, and then click Computer.

Choose a hard drive to check for bad sectors. Right-click the hard drive you want to scan, and then click Properties.

In the Properties window, click the Tools tab.

In the Error-checking section, click Check now.

Check the Scan for and attempt recovery of bad sectors.

You can also check the Automatically fix file system errors to check the hard drive for software-based errors.

Place a check mark within the box next to “Scan for and attempt recovery of bad sectors.”

Click Start. Windows will start checking your hard drive for bad sectors and will fix any that it finds.

Don’t use your computer while Windows attempts to fix errors.

If you have any open files or programs at this point, you’ll get an error message asking if you’d like to schedule the disk check when you restart your computer. If you click Yes, it will restart your computer and perform the disk check.

Review the check disk report. Click the See details down arrow to see more details about your report.

(This is all falls under common hard drive problems)

Method 3 of 3: Windows 8

Move the mouse cursor to the upper-right corner of the screen, move the mouse pointer, and then click Search.

If you’re using the touch interface, swipe in from the right edge of the screen, and then touch Search.

For these steps to work, you will probably need an admin account and password.

In the Search field, type This PC, and then click or touch This PC.

Right-click the drive you want to repair, and then click Properties.

If you’re using touch, press and hold the drive you want to repair, and then touch Properties.

Select the Tools tab.

Under Error checking, click or touch Check.

You may be asked for an admin password. Enter your admin password. If you don’t have one, contact the person who has the admin account.

Review the scan results. The error checking scan will tell you either that there are errors or there aren’t errors. You can still repair the drive, even if there are no errors, but you don’t need to.

Click Scan and repair drive.

Choose when to repair the file system. In the Restart your computer to repair file system errors dialog box, click Schedule on next restart to repair your hard drive the next time you start the computer. Click Restart to repair the hard drive now.

Wait for Windows to scan and repair the hard drive sectors. Do not try to use your computer or interrupt the sector scan while it’s happening.

Surveillance is one of the segments where most of the time normal hard drives being used. However there are surveillance drives available with a little price difference, but performance is far better. On the other hand, surveillance HDDs are built to record data 24×7 from multiple camera streams or channels.

Difference between Optic Modem and Media Converter

Difference between Optic Modem and Media Converter

Fiber Optic Modem

Fiber Optic Modem, also known single-port optic multiplexer, is a point-to-point type terminal equipment which uses a pair of optic fibers to achieve the transmission of E1 or V.35 or 10base-T. Fiber modem has the function of modulation and demodulation. Fiber modem is local network relay transmission equipment, suitable for base station transmission fiber terminal equipment and leased-line equipment.

Fiber modem is similar to the baseband MODEM (digital modem). The only difference from baseband MODEM is that it access fiber line, the optical signal. The multi-ports optic transceiver generally called multiplexer. For multi-port optical multiplexer is normally be directly called “multiplexer”, single-port multiplexer is generally used on the client, similar to commonly used WAN line (circuit) networking with the baseband MODEM, and also named for “fiber modem”, “optical modem”.

Fiber Media Converter

Fiber Media Converter is a simple networking device making the connection between two dissimilar media types become possible. Media converter types range from small standalone devices and PC card converters to high port-density chassis systems that offer many advanced features for network management.

Fiber media converters can connect different local area network (LAN) media, modifying duplex and speed settings. Switching media converters can connect legacy 10BASE-T network segments to more recent 100BASE-TX or 100BASE-FX Fast Ethernet infrastructure. For example, existing half-duplex hubs can be connected to 100BASE-TX Fast Ethernet network segments over 100BASE-FX fiber.

When expanding the reach of the LAN to span multiple locations, media converters are useful in connecting multiple LANs to form one large campus area network that spans over a limited geographic area. As premises networks are primarily copper-based, media converters can extend the reach of the LAN over single-mode fiber up to 160 kilometers with 1550 nm optics.

http://arindamcctvaccesscontrol.blogspot.com/2014/06/fiber-media-converters-for-video.html

Wavelength-division multiplexing (WDM) technology in the LAN is especially beneficial in situations where fiber is in limited supply or expensive to provision. As well as conventional dual strand fiber converters, with separate receive and transmit ports, there are also single strand fiber converters, which can extend full-duplex data transmission up to 120 kilometers over one optical fiber.

Other benefits of media conversion include providing a gradual migration path from copper to fiber. Fiber connections can reduce electromagnetic interference. Also fiber media converters pose as a cheap solution for those who want to buy switches for use with fiber but do not have the funds to afford them, they can buy ordinary switches and use fiber media converters to use with their fiber network.

Main Difference between Media Converter And Optical Modem

The difference between the media converter and optical modem is that the media converter is to convert the optical signal in the LAN, simply a signal conversion, no interface protocol conversion. While, fiber modem for WAN is the optical signal conversion and interface protocol conversion, protocol converter has two types of E1 to V.35 and E1 to Ethernet.

In fact, as the developing of network technology, the concept of media converter and fiber modem has become increasingly blurred, which are basically can be unified for the same equipment. Media converter becomes the scientific name of fiber modem.

Few things need to know, There are two primary types of fiber optic cable, single mode fiber (SMF) and multimode fiber (MMF). The former has a very thin core about 5-10 microns in diameter, which is about 10 percent of the latter. Generally, single-mode optical fibers used in telecommunications operate at 1310nm or 1550nm wavelength while multimode fiber at 850nm and 1300nm. However, sometimes, the subdivision of the two types is different due to various fiber optic cable manufacturers. single mode optical fiber cable is used for longer distances such as 100km compared with multimode fiber under 2km due to the smaller diameter of the fiber core. Therefore, single mode optical fibers are typically used outside between buildings in cable TV, internet, and telephone signals transmission while multimode fibers are used within buildings in backbone applications such as computer network linking.

Normally, fiber optic cable speed rates at 10 Gbps, 40 Gbps and even 100 Gbps.

Generally, one fiber optic cable is made up of incredibly thin strands of glass or plastic known as optical fibers (called “core”) surrounded by an insulated casing (called “cladding). Each strand is a little thicker than a human hair and can carry much data like 25,000 telephone calls. Therefore, an entire fiber optic cable can easily carry as much data as you can imagine.

Planning, design & Errection of Video surveillance systems Code of practice for hotel sector

Planning, Design & Erection of

Video surveillance systems

Code of practice for Hospitality sector

(Proposed)

1. Introduction

Any business that operates within the hospitality sector will be more than aware of how much liability insurance can cost. There are a number of factors that affect this cost.

“Right from the time when someone enters a business premises till the time they leave, the business is held responsible for any kind of misshapen with them.” – This is not just a statement, but one of the biggest risks that all businesses have. In fact, the hotels and hospitality providers are mostly affected by this risk. If a customer or an employee gets hurt in the business premises, the business may have to go through the frustrating and lengthy litigation process.

While some claims can be completely genuine, unfortunately there are going to be some fraudulent and bogus claims. A business has to be prepared to argue their case and provide evidence, which is where the Video Surveillance installation can be a worthwhile investment.

Proper evidence is required to check out the facts which can be provided by CCTV footages. This is the reason why surveillance cameras are often installed in the premises of hotels and hospitality providers.The installation of CCTV equipment can be a one-off cost that acts as a powerful deterrent for opportunistic criminals.

The correct design and use of such systems is paramount to ensure a CCTV surveillance system meets the needs of the user, provides a tangible benefit and provides safety and security for the wider law-abiding public.

NOTE: In this context, the term Video Surveillance System (VSS) synonymous with CCTV.

2. Scope

This code of practice gives recommendations for the planning, design of all Video surveillance systems.

This code of practice has been prepared to assist in this process by taking account of the various standards for Video surveillance systems, and presenting them in a usable framework necessary to achieve an effective security surveillance solution.

3. Planning

3.1 Component

Now we pose a few questions that you need to keep in mind before purchasing your security system.

1.     Where in your hotel theft is most common?

2.     Which are the areas you wish you could capture on tape?

3.     Is the neighborhood around the hotel conducive to crime and theft?

4.     What kind of guests do you receive?

5.     What is your property layout?

6.     Is it a Cottage style property?

7.     Does it have a single building which houses all its rooms and amenities or has more than one building for different purposes?

8.     Does the hotel have a history of employee theft, guest criminal cases, or legal cases pending?

The questions above help determine the quality and level of security that you will need. Usually, hotels with low-risk environments require basic surveillance security and those in danger zones have a high priority security system.

This is not always the case as it also depends on the guests the hotel cater. Business hotels in comparison to luxury hotels or best value hotel have a higher aptitude for security.

The main key component of video surveillance is Camera, Storage (NVR/DVR/NAS) & image Presentation Devices. Video analytics, ANPR etc are optional. There are two technology of Video Surveillance system, Analog & Digital/IP. Here arethe different types Of CCTV Cameras: Dome Camera, Bullet / Box Camera, Zoom Camera, Speed Dome/PTZ Camera, Panoramic Camera.

Business hotels require a closed network surveillance system which can take care of sensitive information and give complete privacy to guests.

3.2. Capturing user need

It is the responsibility of the system specifier or purchaser to identify and record the purpose of the video surveillance system. When planning CCTV systems it is important to remember that there is no ‘one size fits all’ solution. Each site will have its own unique needs based around numerous factors (including nature of site, geographic location, local environment, history of issues). Similarly each end user will likely have their own expectations regarding what the system will do for them (e.g. deter crime, improve detection of crime, monitoring movement of personnel).

If you are a hotel owner or a manager, ensuring everything going right is definitely one of your major responsibilities. Hotel room surveillance is illegal. CCTV security cameras in hotel room are NOT allowed. Installing security cameras in hotel rooms is a serious privacy violation.

Security cameras are legal when being mounted or installed in public areas, such as, lobbies, elevators, receptions, etc.

3.3 Risk assessment

Risk assessment should be performed to ensure the design of the system results in an installation that adequately addresses the threats and reduces the security risks. In order to identify the level(s) of security required (and potentially therefore the grading of the elements of the system), an assessment of the factors which are likely to come into play is required. In very global terms, from a security perspective these elements are typically considered as:

Threat (Who): The threat will typically be defined as the persons or events to be protected against. Threats will vary greatly in termsof objectives, determination, capability, resourcefulness,

Vulnerability (What / Where):The vulnerability will typically be the areas of concern that require protection. The level of vulnerability will be defined by numerous factors such as desirability of the objects in the area, ease of access, operational hours of the environment, exposure / secluded nature of the area.

Risk (What if?): Risk is effectively the consequence of a successful or attempted intrusion or event. These risks can be wide and varied and not immediately obvious. Risks and impact levels of each identified risk will typically vary depending on the nature of site. Risks can include:

1.     Immediate Financial Loss: Immediate value of items lost.

2.     Ongoing Financial Loss: Increased insurance premiums, time to return to profit.

3.   Personal Safety: Injuries to staff and / or members of public involved in violent incident.

4.     Stress Related Issues: Reduced staff morale, loss of staff due to safety concerns.

5.  Non-financial loss: May include loss of intellectual property, company data or similar.

Typically security systems cannot change the identified threat or alter the risk, but well deployed security measures significantly reduce the vulnerability. This in turn helps to reduce the likelihood of risks occurring.

These services are provided in different environments, such as swimming pools, fitness areas, dining halls, common areas and individual rooms. Each area has its own potential risks; for instance, guests can slip and fall near the swimming pool area if not properly maintained or they may get injured in the fitness area. Some of the most common causes of injury in these places are:

1.  Physical Attacks: Although the premises of hotel and hospitality providers are considered safe, in some crowded and low budget hotels, criminals may attack guests for their money. In these situations, the presence of outdoor surveillance cameras acts as an evidence against those criminals.

2.   Slips: Usually, the flooring is not similar in all areas of the premises. The guests being new generally do not pay much attention towards the uneven flooring and so they may slip and fall. Moreover, cracked flooring, worn-out carpets and wet floors are some of the major causes of slip and fall accidents.

3.  Broken Furniture: In order to save money, some hotels do in-house repair of furniture that broke down due to overuse. Because of its age and some guests’ weight, the furniture may collapse and injure the guests.

3.4. Operational requirements and agreeing with the customer

Ideally the Operational requirements (OR) document should be raised by the end-user or their authorized representative (such as a security consultant) and used as the basis for specifying the required system and subsequent performance tests. Planned or possible future expansions to the system, including addition of further cameras, monitoring locations and integration with other systems.

3.5 Target Capture and Image Detail

Detection, Recognition and Identification (DRI) in video surveillance is very important terms to get image details. DRI ranges, expressed in meters, km (or miles), can be found in the specification table of infrared camera brochures.

The terms “Detection”, “Recognition” and “Identification” were defined as follow:

·        Detection: ability to distinguish an object from the background

·        Recognition: ability to classify the object class (animal, human, vehicle,  …)

·        Identification: ability to describe the object in details (a man with a hat, a Jeep …)

As a best practice, do not assume the camera resolution is everything in regards to image quality. For a camera to operate in a day-night environment, (the absence of light is zero lux), the night mode must be sensitive to the infrared spectrum. It is highly recommended to conduct tests or pilot installations before buying large quantities of any model of camera.

A lens is a transparent optical device with perfect or approximate axial symmetry which transmits and refracts light, converging or diverging the transmitted light and to form images. A simple lens consists of a single optical element. A compound lens is an array of simple lenses (elements) with a common axis; the use of multiple elements allows more optical aberrations to be corrected than is possible with a single element. Lenses are typically made of glass or transparent plastic.

The practical effect of this is that a camera may need to have a wider or narrower field of view so that the necessary amount of detail can be seen and that in some circumstances more cameras may be needed, either to increase the area covered with the same detail or to allow for different levels of detail to be seen from the same view.

The measure of the fine detail that can be seen in an image. For analog systems this is typically measured in Television Lines or TVL. Higher TVL rating, the higher the resolution. Same way megapixel (MP) like 1.3mp, 2mp, 4mp, 8mp etc.

Resolution-horizontal
The amount of resolvable detail in the horizontal direction in a picture. It is usually expressed as the number of distinct vertical lines, alternately black and white, which can be seen in a distance equal to picture height.

Resolution-horizontal - vertical
The amount of resolvable detail in the vertical direction in a picture. It is usually expressed as the number of distinct horizontal lines, alternately black and white, which can theoretically be seen in a picture.

The graphic below shows a comparison of the resolutions listed if each pixel takes up the same amount of space.

Key camera areas, include exterior entrances and exits, parking lots, the front-desk area, the lift, the floor corridor, the hotel lobby, cooking area, linen room, bar, casino and swimming pool exterior area.

Account should also be made of the difference between live operation and playback / review operation when considering image size requirements. For example, in a live monitoring situation, where a rapid assessment of the scene or situation may be needed, a higher screen occupation may be required than a system which is required to be more ‘reactive’, whereby little or no live interaction is anticipated and recordings / events can be reviewed in slower time.

3.6 Environmental considerations

Consideration should be given to the need for specialist equipment or installation techniques in certain environments.

Consideration of environmental requirements should be given to areas which may not be immediately obvious. For example where hard disk storage systems are to be installed which may, in their own right, raise the local temperature to an extent whereby artificial cooling methods such as air conditioning are required to help ensure longevity of the equipment.

3.7 Regulations and Legal Requirements relevant to CCTV

There are many legal requirements and regulations that apply to CCTV including those listed here. It is the responsibility of the owner, installer, maintenance company and operator to ensure compliance with these as appropriate to their activities and location. Consideration should also be given to other byelaws introduced by local government. These will vary from region to region.

The following Acts of Parliament are known to affect the majority of CCTV installations and use of CCTV but others will apply in specific circumstances:

1.     The Human Rights Act 1993(Amendment Act, 2006)

2.     The Data Protection Act 1998 (DPA).

3.     The Right to Information Act 2005

4.     The Private Security Industry Act 2005

5.     The Clean Environment Act

1.   Design

4.1. Site Survey

A site survey should be conducted to take into account specifics of the site along with the OR. Locations of interest should be established and documented on the site plan. Accordingly select camera type, quality of picture etc. The site survey should consider lighting. Depending on circumstances day and night time surveys may be required.

The performance of a CCTV system is primarily dependent upon the available light level. It is important, therefore, that the limits of light levels within which a CCTV installation is intended to function are expressed in units of illumination (e.g. lux).

Light levels are normally measured in lux, the SI unit of luminance. In some cases the amount of light will be quoted in foot-candles. One foot candle is approximately ten lux. Lux levels apply only to visible light spectrum and are not relevant to infrared systems

Lux is measurement of the intensity of light. It is equal to the illumination of a surface one meter away from a single candle.

The survey should be used to decide the positioning of all key equipment of the system along with the necessary environmental protection requirements.

The site survey should consider power and device interconnection together with provision of local power supplies, routing of cables, wireless links, etc.

During the survey consideration should be given to how the equipment will be installed and other considerations such as accessibility, access times, need for closures whilst equipment is being installed and accessibility for maintenance.

4.2 Equipment Selection

Equipment means Camera, Storage, software, Viewing monitor etc. Consideration should include environmental factors (e.g. efficient use of power, disposal of consumable items, and control of hazardous substances).

4.2.1 Camera and lens

A camera and lens should be compatible and should be selected to cover the area to be viewed, taking into account any person or object required to be identified. See section 3.5.

Selection of the correct lens type is as important as the camera selection. A poor lens performance can significantly detract from the overall performance of the system. For further information refer to BS EN 62676-4 clause 6.5.

4.2.2 Sensitivity of Light

When selecting a camera for a particular application, consideration should be given to the type of light source and the spectral response of the imaging device in addition to the scene reflectance and lens. Available light level will have a major influence on the choice of camera and typically the sensitivity of a camera measured under laboratory conditions may not match results under natural operating environments. There may be a trade-off between higher resolution cameras and a reduction in sensitivities.

Wide dynamic range cameras can help compensate for large variations of luminance across a scene and provide acceptable exposures simultaneously in the brightest and darkest areas of the image.

4.2.3 Field view

The width and height or area desired to be covered by one camera. This area is determined by the focal length of the lens on the camera and the distance the camera is mounted from the scene.The equipment selection should ensure the field of view matches the system’s operational requirements.

4.2.4 Illumination

A video surveillance camera requires a certain amount of lights produced by natural or artificial illumination. The amount of lights is defined by LUX(Lumens per Square Meter). Depending on the choice of camera equipment and the system’s operational requirements extra illumination may be required.

Refer to BS EN 62676-4 clause 6.9 for points to consider e.g. positioning, beam pattern, maintenance, deterioration of light source with age, unwanted reflections, type of lighting and switching

4.2.5 Housings and mountings

A camera and its supporting hardware should be securely mounted. The camera mounting bracket orpole should safely support the weight and windage of the camera and of any associated hardware. Remember that a small amount of deflection in a pole when a camera is fully zoomed in at a distant target will result in large degrees of movement in the scene.

Consideration should be given to the environmental conditions in which the equipment is intended to operate with respect to the additional features which may be implemented into housings i.e. heaters, wipers.

Protection against malicious damage either though forceful impact, scratching or burning plastic windows or dome bubbles, or spraying should be addressed by using a combination of housing specification and physical positioning.

All equipment installed should be suitable to withstand the prevailing environmental conditions according to the environmental classes in BS EN 62676-1-1. This includes protection against dust, particles, water and any special environmental conditions that may prevail on the site (e.g. corrosive or explosive atmospheres).

4.2.6 PTZ Mechanisms

PTZ indicate Pan, Tilt & Zoom, so a camera having this three feature is called PTZ camera or speed Dome camera. Hotel Parking area, main gate entrance, open out door space, swimming pool, playground, sea beach etc area should cover by speed dome camera.

The maximum required pan and tilt rotation angles and any intermediate preset stops is required. IP66 based enclosure should protect out door speed dome camera.

4.2.7 Powering

Consideration should be given to the power requirements of the system. This includes:

• Local or centrally powered (Must be UPS power)

• Mains or low voltage. (110V to 220V AC)

• Back up / Stand-by power in the event of mains failure.

For Power over Ethernet (PoE) consider the potential need for high power PoE supplies for certain cameras, especially ones with in-built illuminators, heaters or motorised PTZ functions. For PoE also consider the limiting distance factor of 90m in order to deliver the maximum power from the power sourcing equipment (PoE injector) to the powered device. Greater distances will adversely affect performance of the cabling including bandwidth.

The outdoor surveillance cameras record everything in real-time and this recording is stamped with date and time. This becomes a proof of evidence in determining whether the claims are genuine or fake. Sometimes, it happens that guests get injured by their own mistakes, such as because of being drunk or careless attitude. In such cases, the guests usually file a lawsuit against hotels and hospitality providers. Unfortunately, most of the cases result in favor of the guests because hotels do not have any evidence to defend themselves.

4.2.8 Video performance

Equipment and system design should take into account the need to achieve performance levels and characteristics as stated in the operational requirements. This should include consideration of frame rate, resolution and quality of live and recorded images both for human viewing and for automated video analytics.

In cases of injuries borne on the property, CCTV ascertains whether the injury was because of misbehavior of the guest, or an accident, or the negligence of the business organization itself. Suppose a drunk guest was misbehaving with the decorations in the open area of the property and then they got injured. In such a case, they may blame the hotel authority and file a lawsuit against them. But if the hotel has CCTV recordings collected from the CCTV outdoor surveillance cameras, they can easily prove their innocence and huge compensation money can be saved this way.

There are some people who try to make some quick money by filing a fake lawsuit against hotels or hospitality providers.  It is commonly known that most slip and fall cases happen near the pool area. Over there, some guest may get injury by colliding with someone else and may complain that the injury was a result of the hotel’s negligence near the pool area. If outdoor surveillance cameras are installed in the premises, then by seeing the recording, the hotel authority can easily prove that the injury was nothing but a result of collision. But if there was no CCTV installed then a lawsuit could have swept away thousands or even millions from the hotel’s account.

4.2.9 LAN Switches and Provisioning

LAN switching requirements are covered in the necessary detail for a successful deployment. There are several requirements for LAN switches, the primary being the ability to support the 802.1af PoE standard for those cameras that can make use of this feature. Also, aggregate backplane capacity as well as uplink capacity is important. At a minimum, switches should have 1Gigbps or 10Gigbps uplink and a 32Gbps effective backplane capacity. QoS support is also important, the ability to both trust the Layer-3 QoS markings (DSCP) and to set DSCP on ingress is critical. Most of commercially available switches support VLANs and trunking and these features are critical for segmenting IP video surveillance traffic into its own domain.

Support of features like port security, 802.1x port-based Network Access Control (NAC), Spanning Tree Protocol (STP) PortFast feature, and PortFast Bridge Protocol Data Unit (BPDU) guard are also useful. Because this design guide recommends marking video surveillance media streams as DSCP value CS5, switches that are configured by default for VoIP implementations are recommended as the media feeds will align with the default VoIP configurations.

4.2.10 IP Addressing Requirements

If the network manager plans on implementing some segmentation and path isolation over the LAN/WAN by using VRF-Lite and VLANS, the IP addressing scheme may have greater flexibility than if the video surveillance networks are routed in the global routing table. However, the general recommendations for addressing IP video surveillance devices are as follows:

• Allocate an addressing scheme distinct from the end-user address space at the branch locations.
• Allocate network addressing so that IP cameras, servers, encoders, workstations, and any hotel building management (BM) devices can be allocated from the address space at the remote locations.
• Allocate addressing to facilitate summarization of network advertisements to the core.
• Allocate addressing so that one network advertisement can encompass the entire address space for physical security (and building management) devices.

• Configure a loopback address on remote routers from the physical security address space for NTP and other management functions.

Because the IP cameras are using static IP addresses, give careful attention to IP addressing deployed as reallocating IP addressing is more time consuming than when all end nodes use dynamically assigned IP addresses from a DHCP server.

4.2.11 Storage

The total storage requirement for a digital CCTV recorder should be estimated before a system is installed, so that hard drives of the appropriate capacity can be specified. It is vital to ensure that sufficient capacity is available so that compromises do not have to be made on either the image quality or retention time.

The storage requirement will depend on factors such as whether just video, or video and audio are being stored, frame size, required number of frames per second, number of cameras, bit rate of video and audio streams, retention period, requirements for storage resilience (e.g. mirroring or RAID storage), and operating system overhead.

In general, the recommendation is to store data as close to the source as practical. This is especially true of branch location deployments. By storing video archives locally, IP video surveillance may be deployed to locations with traditional WAN links that would otherwise not have enough bandwidth to transport the archives to a central campus/data center facility. The WAN, however, may still have sufficient bandwidth to transport or view video clips to aid in investigations or other forensic analysis. By storing locally and only transporting the small amount of video surveillance data that is needed centrally, video surveillance can be network-enabled today and tied into other BMS and analytics solutions that can benefit the business.

When using MJPEG streams, the frame size of each image plays a key role in estimating the storage and transmission requirements. Since each frame is unique and varies according to the image complexity, it is difficult to provide a guide that provides fixed frame sizes. An IP camera that provides images with low complexity will generate smaller frame sizes. Smaller frames will require less bandwidth and storage capacity.

The following formula is used to calculate the bandwidth requirements for MJPEG streams:

MJPEG storage = Average Frame size x Frame rate x duration

Example 1: For an 8-hour archive of a CIF video stream with 50 percent quality and 15 frames per second, the following is the calculation:

4 KB  x  15fps  x  3600s  =  216,000 KB/ hour

                          = 216MB /hour   x   8 hours

                          = 1.728 GB

Example 2: For a 24-hour archive of a 4CIF video stream with 100 percent quality and 5 frames per second, the following is the calculation:

320 KB x 5fps x 3600s  =  5,760,000 KB /hour

=  5,760MB /hour  =  5.76GB /hour x 24 hours. =  138.24 GB

The following formula is used to calculate the bandwidth requirements for MPEG-4 streams:

MPEG4 storage = Bit rate (kbps) x duration

The target bit rate is configured on the camera and is already expressed in bits per second.

Example 3: For an 8-hour video stream with target bit rate of 768kbps, the following is the calculation:

768kbps / 8 bits/s = 96 KB /second  x  3600 s

                   = 345,600 KB/hour  /  1000

                   = 345.6 MB/hour  x  8 hours

                   = 2.764 GB

There is no standard length of time that video surveillance recordings must be maintained in the hotel. Usually, hotel video recording tapes will be kept about 30 — 90 days. However, some regulations require that the recordings of the hotel security cameras in the casino need to be stored for 6 months or 1 year.

4.2.12 Image Presentation Devices

The image presentation device(s) should be selected after taking account of the nature of the image viewing task, the conditions in the control room or other viewing space and the need to identify, recognize, detect or monitor. It should be considered whether displays are also used for viewing maps, floor plans, device lists, system status, alarm conditions, etc.When displaying images where a significant amount of movement is present (e.g. traffic / Cab entry exit) display refresh rates and resolutions should be matched to the image source.

Display screens have different resolution depending on set-up and type. Display resolution should be selected to match and complement the camera resolution and resultant video resolution.

For larger display surfaces, the efficient display resolution can be defined according to the minimum visible size of a pixel. The size and resolution of display screens should be considered together with the recommended display sizes. An operator placed at a large distance may not be able to discern the details of a small high-resolution monitor.

CCTV cameras not only save businesses from lawsuits but also keep the guests tension-free at all times. The concerns of the guests regarding their expensive cars are automatically resolved when they see the parking area is monitored by outdoor surveillance cameras. Some businesses may not be too wealthy to appoint a security guard in every sensitive area of their premises, so going for CCTV cameras will be a good idea. It is a one-time investment that constraints the effort of opportunistic criminals.

4.3 Proposal Including System Design Site Plan

Once the site survey and Operational requirements (OR) is completed the CCTV system can be designed and a System Design Proposal (SDP) prepared.

Where an OR is not available, as may be the case for less complex CCTV systems, the SDP, drawn up as part of the process of ascertaining the customer’s needs, expectations, and patterns of usage of the premises, forms the basis of the agreement between the installing company and the customer as regards the CCTV system to be supplied. At appropriate stages checks should be made to ensure that the proposed implementation will meet the customers’ operational requirements. The operational requirement and matching test procedure is essential to assess whether the system can meet its required purpose.

The design should take into account the various requirement and location factors identified in the previous stages. At this stage a site plan should be drawn up, including locations for the various key components e.g. cameras (including field of view), and PTZ preset positions, detectors (including range and coverage), control rooms, power supplies, interconnections, etc.

The system design proposal should stipulate the conditions under which any test image(s) should be used. For example if the system will be used in both day and night conditions then separate tests should be performed for the different light conditions.

The site plan may be drawn on CAD, or be a hand drawn sketch with annotated pictures taken by a digital camera as appropriate

Any change to site plans, installation plans, system designs and/or logical architecture should be included and attached to the final documentation and it should include change permissions and risk/issue/logs generated during the installation process

4.4 Video transmission

Video transmission describes the transfer of video from a capture device (camera) to a viewing device (or software), a recording device (or software) or to a storage device using switched networks. The networks may be hard wired or may be wireless. Networks may combine different methods of transmission, e.g. typically described as analogue or IP.

In the case of both wired and wireless networks, sufficient defences should be put in place in order to protect the end user to ensure that the video transmission system is not vulnerable to attack from outside potentially rendering the asset unprotected, or used as a means of penetrating another network to obtain otherwise confidential information.

The use of IP technology is becoming more widespread across a variety of applications and industries. The security industry is no exception. IP can often be used to provide a cost-effective means of installing/monitoring security systems by exploiting existing infrastructure and enhancing and/or replacing older arrangements

If an Alarm Receiving Centre (ARC) wishes to provide remote monitoring & remote viewing of IP enabled systems, they will have to design and implement robust network solutions

A network can be built up from many differing types of service. One of the more common is ADSL (Broadband) but there is also SDSL, leased lines, megastreams, kilostreams, GPRS (Cellular network), ISDN Dialup, PSTN Dialup and quite a few other options in the form of direct links to service providers.

4.5 Bandwidth requirements

While one single alarm system uses very small amounts of bandwidth, monitoring several hundred or even thousands could have a dramatic impact on the ARC links, i.e. consider open/close signals happening at more or less the same time every day from all systems.

It is unlikely that all these signals would be sent at exactly the same time so bandwidth is unlikely to be of major concern to the ARC for a small number of systems. However, as you start to calculate bandwidth requirements for CCTV you can see that you quickly begin to use up the available bandwidth.

For alarms, you should be more concerned with hardware systems able to process a high number of systems simultaneously. e.g, firewalls, receivers/servers.

However, a CCTV system sending multiple data streams could require significant bandwidth in much the same way as a DoS attack (Denial of Service). There should be systems in place to address these concerns.

There are various benefits of installing CCTV cameras in hotel premises. Some of them are discussed below:

• Beside rooms, there are various facilities that hotels provide such as spa, gym, swimming pool, etc. Presence of CCTV at these places helps to identify intruders and management can take quick action to restrict them from entering the place.
• CCTV cameras help curb unwanted access like that of intruders and uncategorized customers to hotel facilities like spa, pool or Gym etc.
• The presence of CCTV cameras in hotel parking, corridors and entrances give a sense of security to the guest. This has become a major selling point in hotels today as people tend to move to hotels who enlist security as their main priority.
• 24/7 surveillance facilities of entry and exit areas help restrict trespassers from entering the premises.
• CCTV when installed in storage or maintenance rooms of hotels helps in preventing a possible theft by employees. Employees also hesitate to do any unethical activities when they see a CCTV camera is installed and realizes they are being monitored.
• Presence of CCTV cameras in hotel’s building and especially in parking area gives mental peace and satisfaction to guests.
• There are some unexpected activities such as slips, falls or fights that happen with guests. In such cases, the customer files a lawsuit against the hotel and demands alimony. To bring the truth out, management should analyse CCTV recording and if they find that it happened because of negligence of hotel, they should quickly resolve the matter with client. If they see that hotel is not responsible for whatever happened, they can counter the allegation and can use CCTV footage as evidence.
• These footage play a key role in evading fraud lawsuits against the hotel and gather evidence in investigations. In case of in-house charges, CCTV camera footage help prove hotel claim or accusations against guests and in case of criminal investigations help the police gather evidence.
• The hotel industry is a very competitive industry. Every hotel owner implements new technologies to gain competitive advantage and attract more and more customers. One such latest tech practice is CCTV surveillance. The management of hotels choose from various CCTV packages available in the market and makes their premise safe and secure.
• There are some guests who harm the property such as damaging furniture in common area or the decorations and when they are fined, they deny. In such cases, CCTV footage acts as an evidence and strengthens the hotel’s viewpoint.

Maintaining a CCTV surveillance system in your hotel is very easy nowadays. For live viewing, you can install one without DVR and can easily monitor everything live and if you want a recording of all the activities then you can go for CCTV systems that come with DVR or can be attached to your computer. With technological advancement, wireless CCTV cameras are also available in the market and CCTV installation has become a very easy task.

When CCTV cameras are installed in your hotel premise, you and your guests can remain tension free and focus on the event. While installing the cameras, the management should consider that the cameras does not invade the privacy of guests in any manner, the only purpose of installing the cameras should be safety and security of the guests and hotel premise.

5.   Installation

5.1 Evaluation of Equipment

Where a customization of a product/software is undertaken in order to meet specific user needs, the customization should be tested equipment before being deployed. The customization should also be tested against the user need defined. Equipment may be required to exchange information in order to perform a function of some kind (for example, to move a PTZ camera to a position based on an input from another system, or increase the record rate and resolution of a device based on the inputs from another device). In these cases it is recommended the successful operation of the devices be tested first before being deployed. This is particularly recommended if the equipment is made by different manufacturers.

5.2 Cable laying

Security camera cable is an important part of CCTV industry. The requirements of BS 7671 (Requirements for electrical installations, IET Wiring Regulations) should be met using the edition current at the time of installation.

All interconnecting cables should be fixed and supported and installed to conform to good working practices.

As we all know wired CCTV camera footage totally depend on the wiring system. If cabling exposed, then it can be get tempered and you cannot get a video for a crime evidence. Each and every cable of the camera never revealed, especially for the outdoor environment. Covering all camera cable, also reduce the service issues.

Possible fixings and supports include:

• Conduit: when metal (MS) is used, suitable bushes or grommets should be fixed to each end to prevent damage to the cable. When conduit is used to carry the cable it should terminate as close as possible to the unit to be connected.

• PVC or metal trunking: where trunking is used to carry the cable it should terminate as close as possible to the unit to be connected.

• Insulated clips

• Cable ties

• Catenary Cables: When overhead catenary wires with loop holders or plastic buckles are used the supporting wire should be securely attached to the building. Self-supporting catenary cables may be used provided they are correctly designed.

Camera cable is basically manufactured in such a way that it should optimize video signal quality. CCTV camera cable is composed of two sub cables that will run simultaneously for transmitting both video and power signal, Analog Video transmitting cable  also called RJ59 Cable, one sub cable is the central solid copper conductor core shielded by dielectric material, then further shielded by  copper or alloy braid that will transmit video signal and another is  power cables that will transmit  power and both two-part is insulated by PVC having diameter of 5.5 mm to 7.5 mm. IP Video transmitting cable called CAT6 / CAT 6A etc.

All cables should be of a type and size appropriate to the application and should take account of transmission rate, electrical interference and voltage drop.

Any plastic or PVC component used as part of the installation of cables should be suitable for the environment in which it is installed. Externally mounted ties and clips should be made of UV-resistant material.

Environmental conditions such as dampness, excessive heat, risk of corrosion, mechanical or chemical damage, should be taken into account when determining the degree of protection required for cable runs.

Any cables used underground should be suitable for that purpose and have adequate protection from mechanical damage. Underground cables should provide a high level of resistance to dampness, chemical reactions, corrosion and rodents.

5.3 Power SuppliesEquipment

Power supplies should be capable of meeting the largest load likely to be placed upon them under normal operating conditions. The maximum load on the power supply typically occurs during start-up of the system following a power failure. The assessment of the electrical current demands for design purposes should also include an extra tolerance of 5% to 10% over capacity.

Where safety and security considerations do not require continued operation of the CCTV system during a mains supply failure, the public mains supply may be the sole supply for the system.

Power supplies should be located within a secure area, in a position safe from tampering, and should be ventilated in accordance with manufacturers’ requirements for safe operation.

All equipment housings should be clearly marked with the operating, or supplied, voltage, whichever is higher.

The installation and position of additional power supplies should be considered if voltage drop across cables is likely to reduce the voltage to equipment to an unacceptable level. Alternatively, in some cases, it may be possible to reduce the voltage drop in the cables by using cables with less resistance, greater conductor size or by using more cores of a cable for the supply of power.

5.4 Camera Equipment

In CCTV installation, the position of the camera plays a major role.  if you want to record a good footage from CCTV camera then you need find a best place for it.Cameras should be mounted in positions free from obstructions and, wherever possible, not directly viewing bright light sources. The mounting position should allow installation and maintenance to be carried out in a safe manner.

If cameras are to be mounted on towers or brackets the following environmental considerations should be made:

§  Rigidity, taking into account potential wind velocity, equipment type and equipment mounting and fixing positions.

§  Electrical interference and the possibility of damage by lightning (see BS EN 62305).

§  Dust, airborne particles and other potential sources of corrosion or contamination.

§  Condensation inside housings and other equipment due to changing temperatures.

Tower and bracket equipment should be installed according to the manufacturer’s instructions and within loading specifications.

Where movement of towers is possible, cables and cameras should be installed with their safety and protection against tampering taken into consideration.

The alignment and mounting of line of sight transmission equipment (e.g. optical and microwave) is often critical and consideration should be given to the method of alignment and to the rigidity of the mounting.

Wired connections should, wherever possible, be concealed. Mechanical protection of flexible cable to movable cameras should be considered where physical damage is a possibility e.g. metal conduit or flexible conduit.

The camera should be installed in such a way that it is difficult for an unauthorised person to change the field of view of the camera. This can be achieved by installing at a suitable location and height, the use of appropriate physical mounting and possibly further by the use of security fixings.

Consideration should be given to the detection of loss of video signal, camera obscuring or blinding on any connected camera. An audible and/or visual system alarm should be generated to inform system operators that acknowledgement is needed and, if defined in the OR, this alarm should be mapped to an output for connection to an alarm system.

5.5 Recording Equipment

The environmental conditions under which equipment will be expected to operate should be taken into account and environmental housings affording appropriate protection should be specified.

Equipment should be installed to manufacturers’ instructions. To reduce the risk of condensation a heater should be installed within housings that may be subject to changes in temperature.

Where there exists the possibility of penetration by solid objects, dust or water, housings that afford appropriate environmental protection should be used. This is typically quoted as an IP Rating. To prevent tampering, lockable enclosures should be considered to house the control and recording equipment. A method of user name and password to access control functions should be considered to restrict access to authorized operators.

For all control and recording equipment the following should be taken into consideration:-

•         Temperature.

•         Airflow of equipment (front to back, side to side, bottom to top, etc), ensuring that the layout of equipment does not have these intakes/outlets blocked.

•         Humidity.

•         Dust and other air contamination.

•         Vibration.

•         Electrical interference.

•         Rigidity, taking into account high wind velocity.

•         Ease of access for maintenance and service.

•         Convenience of operator use.

5.5 Display Screens

Display screens may be desk or wall mounted with consideration given to the ergonomics of the operator. The display screens should be installed to minimise the effect of lighting, particularly sunlight, which can adversely affect the viewing experience. Wall or ceiling mounted display screens should be mounted using suitable brackets in accordance with manufacturer’s instructions.

Consideration should be given to the positioning of such screens to ensure they are above head height or not in a position where people may bang their head on them.

Dos and don’ts of CCTV installation

The do’s in this section are your go-to suggestions for the maximum utilization and best establishment of your CCTV network.

1.     Place at least two cameras at the entrance and exit gate. So, that you can get a clear view of the people entering and exiting the hotel.

2.     Install cameras in all open areas of the hotel which is accessible by all the guests like the pool, park, lobby, service corridor, loading dock, service exit, and stairs. Stairs and service exit are most commonly left out of the surveillance system as they are considered place less visited or used by the guest. But this is where most systems fail as in most cases these become grounds for suspicious activities.

3.     CCTV cameras are important in rooms which store safe deposit boxes, money or sensitive information as these are the places which have the most chances of theft. Though not regularly followed, it is advised to have hidden cameras in these locations because in most cases criminals find a way to avoid detection once they know where the camera is installed.

4.     CCTV security network should be developed all around the hotel from every angle to protect the hotel from the neighborhood and unauthorized access.

Don’ts of CCTV installation: The Don’ts majorly focuses on measures to prevent infringement of privacy. In this network of CCTV cameras and cyber-security, privacy has become a major concern.

1.     According to the hotel security and camera law, hotel room surveillance is illegal. So, avoid installing cameras in rooms, you can install them in corridors so that you know who went into the room and when.

2.     Don’t be swayed by the sales pitch, always opt for security systems which use Category 5 or Category 6 twisted pair cables. Outdated tech is prone to hacking, so it’s advised to have the latest.

3.     Don’t waste your budget on Pan Tilt Zoom cameras, hoping to cover a large area with zoom. It is not true nor is it efficient.

4.     Don’t mount all your cameras on your on the ceiling or 15 feet walls. The height of the camera prevents you from getting a good look at faces.

5.     Avoid installing cameras in angles which could capture images inside a bathhouse, washroom, and spa or massage center on the hotel premises.

There are a lot of do’s and don’ts to hotel security but this will give you a basic lay of the land Technology is moving leaps and bounds every year and it’s important to keep your system updated to beat the competition.

6. Commissioning, Handover and Documentation

Commissioning should consist of the inspection and testing of the installed system by the installation technician/engineers; handover requires the demonstration of the system to the user and the subsequent acceptance of the installation by the customer along with proper manual / handing over document.

6.1 Testing & Commissioning

A CCTV system test plan should be agreed and the tests should be selected to demonstrate during handover that the CCTV system meets the agreed specifications.

This should include testing of the following aspects of the system(s):

• All wiring is correctly terminated.

• Supply voltage is correct to all appropriate parts of system. Where extra low voltage cameras are used, the voltage at each camera should be recorded.

• Operation of all monitoring, switching and recording equipment (including time synchronisation) is satisfactory, including playback equipment.

• Interfaces with alarms (e.g. movement alarms, fences) are satisfactory and triggering of alarms is correct.

• Beam interruption detectors are aligned correctly, where used for triggering the CCTV system.

• Appropriate notices to indicate CCTV in operation have been provided.

• All indicator lamps are working.

• If a standby power supply is specified, ensuring that the system continues to operate correctly to specification when the mains supply is disconnected.

This should also include testing of the following aspects for each camera:

• Camera type and lens fitted is correct for each position.

• Operation of all automatic and / or remotely controlled camera functions (e.g. pan, tilt, zoom, focus, electronic iris and wiper) is satisfactory.

• Correct setting of all pan and / or tilt limits.

• Camera movement, and field(s) of view seen through the appropriate monitor(s), is correct and free from obstruction.

• Operation of electronic irises and focus is satisfactory under the range of intended light levels (night conditions may be simulated through use of suitable neutral density filters).

• Satisfactory operation of supplementary lighting.

• Warning labels are in place in respect of possible sudden movement of camera positioning equipment and in respect of any devices that could cause injury, including damage to the eye.

There are test methods given in:

BS EN 50132-7:2012, Annex B or C

BS EN 62676-4, Annex B or C

These test methods may be used wherever an objective evaluation is required to confirm that the required performance can be obtained. The use of the test methods listed above is a matter for agreement between customer and installer and is not a requirement for every installation. Other test methods are permissible.

Commissioning should include visual and functional testing to ensure that:

a) The system is installed in strict accordance with the agreed specification and that the standard of workmanship is high, and

b) The commissioning requirements of this Code of Practice and BS EN 62676-4 or EN 50132-7 are met.

6.2Handover

At handover, the installing company should:

• Demonstrate all aspects of the system operation to the customer, including any necessary safety precautions.

• Ensure that the correct documentation (see 6.3) is given to the customer to enable the system to be operated, adjusted and maintained.

• Train the system user(s) in its correct operation and arrange for any necessary future training.

• Ensure that users know the procedure for summoning assistance in the event of system malfunction.

Following handover the customer should be asked to sign an acceptance document and to enter any confidential information (e.g. passwords which restrict user access to engineer and other reserved functions) required to make the system perform to the agreed specification.

Access to CCTV recorded images needs to be restricted and tightly controlled for Data Protection Act purposes. This means staff should only have access if they need it to achieve the purpose of the scheme. Third party access should be limited to law enforcement, prosecution agencies, legal representatives, the media (when assisting to catch a criminal) and people whose image has been recorded (unless it would prejudice criminal proceedings). All requests and reasons for denial need to be documented.

If individuals want to view recorded images of them, they need to apply to the data controller in writing and pay a small fee (max Rs50). The data controller must deal with the request within 30 days – even if it is to deny their application.

6.3 Documentation

Upon completion of a CCTV installation there should be a record for each system making up the installation, which should include the following information where appropriate:

a) The name and address of the protected site.

b) The name and address of the customer.

c) The location of each control unit and the type and location of each camera and its associated hardware.

d) An indication of the camera view(s), their purpose(s), and the area(s) protected should be documented. The camera view(s) may be provided in the form of a drawing, a hard copy printout or a video recording.

e) The type and location of power supplies.

f) Details of those cameras that the customer has the facility to manoeuvre or isolate.

g) The type and location of monitors and indicating and / or warning devices.

h) Manufacturer’s documentation relating to equipment and its operational settings/controls.

i) Full instructions for the correct use of system, including details of routine testing procedures and any necessary maintenance requirements (see 7); possible sources of interference with the system and equipment with which the system itself will interfere should be identified.

j) The operation, storage and cycling of recording media.

The make and model number of all items of equipment should be stated in the system record. The system record (i.e. for the “as installed” system) should be agreed with the customer and a copy provided to the customer.

The customer should be offered drawing(s) of the CCTV installation. Where symbols are used in drawings, a key to these symbols should always be provided to enable customers to understand the content of the drawings.

The customer should be provided with the record of the results of the objective test where this was agreed to be a requirement.

All documentation referring to a security system should be kept in a place to which access is restricted to authorized persons.

6.4 CCTV Signs

Your guest needs to be aware that they are entering hotel area that is being monitored by CCTV surveillance equipment. Signs should be placed so that they are clearly visible and legible. The size of the sign will vary according to the circumstances of its location.

7.0 Maintenance

Effective and regular maintenance of a CCTV surveillance system is essential to ensure that the system remains reliable at all times. Regular maintenance by a service company, and effective failure reporting by the user, will enable potential problems to be identified at an early stage so that appropriate action can be taken.

A maintenance agreement should be agreed between the service company and the user of the CCTV system and should include the following:

• Preventative maintenance visits - Planned servicing of a system, carried out on a scheduled basis.

• Corrective maintenance - Emergency servicing of a system, or part thereof, carried out in response to the development of a fault.

• User maintenance - Basic responsibility of the user to maintain operation of the CCTV system.

8.0 Monitoring

Monitoring requirements of a CCTV system will vary greatly dependent on many factors, such as whether there is a need to view live and / or recoded images, whether the monitoring be done locally and / or remotely, the complexity of the CCTV system and the type of response required be it a guarding, key-holder or perhaps police response.

For the data that you receive from CCTV surveillance cameras to be of any use, the images produced need to be as clear as possible. Frequent checks need to be made to make sure the equipment is performing properly and if tapes are being used they need to be of good quality. If the quality of the images deteriorates to an unacceptable level, the equipment should not be used and should be replaced.

Images should not be retained for longer than necessary if they aren’t required for your purpose. Retained image integrity needs to be maintained to insure its evidential value and to protect the rights of the people who have been filmed.

Images should be erased after the retention period or stored in a secure place if being used for evidence. The reason, date, crime incident number and location need to be documented when they have been moved to another location.

Authorized employees should only be able to monitor the information from your CCTV surveillance equipment. All recorded image viewings should be restricted to a designated staff member who can decide if a third party may view the recording.

8.1 Control Room

Attention should be given to the ambient lighting within the control room and, if the room has windows, how sunlight will affect the operators’ ability to monitor the system. This may influence the overall control room layout or require additional window blinds.

If the CCTV system has a requirement for live viewing, camera control, system management, or any other human intensive tasks, a control room should be specified to house these functions. The ‘control room’ could be a single workstation, or a large operations center.

The operator should be presented with a manageable number of CCTV feeds (e.g. is the operator able to suitably view 8 cameras and perform the viewing tasks related to all of those camera views, and their anticipated levels of activity?).

The camera view should be presented to the operator at a size sufficient to allow them to undertake the viewing tasks as above either routinely or by manual or automatic switching of views. (E.g. is the operator being presented with views intended for identification tasks, but displayed as part of a quad view, at a lower resolution, reducing the amount of information available to the operator?).

Spot displays should be positioned directly in front of the operator at between approximately 0.5 – 1.5m and of a sufficient size. They should also be placed so that the operator can easily turn their sitting position to face the displays.

8.2Incident Response

Locally agreed procedures should detail the action to be taken in the event of an incident. These procedures should conform to those laid out as below:

• Action to be taken

• Who should respond?

• The timescale for response

• The times at which observation should take place

• The criteria for a successful response

•CCTV operators should maintain a record of all incidents in the appropriate incident log.

The overall indicator of successful response to incidents is that the CCTV scheme fulfils its objectives, i.e.:

• Restoration of tranquility

• Dispersal or control of the situation

• Prevention or minimization of injury and damage

• Reduction of crime and disorder, to improve safety and reassure the guest

• Identification of a suspect

• Gathering relevant information to assist in the subsequent apprehension of offenders

• Apprehension of a suspect with evidence

• Guest safety through effective evacuation

• Traffic flow restored

8.3 Recording quality and storage

No more images and information should be stored than that which is strictly required for the stated purpose of a surveillance camera system, and such images and information should be deleted once its purpose has been discharged.

Recorded material should be suitable for evidential use as required by the courts if it is to be admitted as evidence; it is therefore essential that recorded material evidence maintains total integrity and continuity at all times. Appropriate security measures should be taken to prevent unauthorized access to, or alteration, disclosure, destruction, accidental loss or destruction of recorded material.

Access to retained images and information should be restricted and there must be clearly defined rules on who can gain access and for what purpose such access is granted; the disclosure of images and information should only take place when it is necessary for such a purpose or for law enforcement purposes.

Data should not be released to Hotel outside the ownership of the CCTV scheme, other than under guidelines referring to the release of information for the purposes of identifying alleged offenders or witnesses, in accordance with the particular CCTV control room’s policy and procedure.

8.4 Media use, storage and disposal

Recorded material should be stored in a secure environment, so that the integrity of the media is maintained. This includes recorded material that has been requested by the law enforcement agencies or contains a known incident. Controlled access to the recorded material storage area should be strictly maintained. Data that is to be destroyed should be destroyed under controlled operation.The register should show the life of the media at all stages whilst in the owner’s possession; such a register may also show itself to be useful in enabling evaluation of the CCTV scheme.

The register should include the following:

• Unique equipment reference number.

• Time/date/person removing equipment from secure storage for use.

• Time/date/person returning equipment to secure storage after use.

• Remarks column to cover additional points (e.g. erase/destroy/handed over to law enforcement agencies/removed from recording machine).

• Time and date of delivery to the law enforcement agencies, identifying the law enforcement agency officer concerned.

• In the event of a non-automated system of erasure of data, the time/date/person responsible for erasure and/or destruction.

8.5 Exporting recordings

When exporting recordings the following procedure should be followed:

• Maintain records of the operator(s) of the equipment. This enables the manager to establish who was operating the equipment at any given time.

• Record without interruption, wherever practicable. Any interruption should be logged.
