Convert HDMI to RCA

Nowadays, most consumer electronic devices support the HDMI (High Definition Multimedia Interface) output for video and image downloads. Before HDMI became popular in the electronic industry, RCA connectors (yellow, white, and red cables) were primarily used to connect DVD players, video game consoles, and set top boxes to televisions or monitors. A common issue for consumers is converting their HDMI devices to RCA cable inputs in order for them to play on older television sets or monitors.

How to Convert HDMI to RCA

Step 1 – Search for an HDMI to RCA converter at a local electronics store or online. The output that the HDMI format will be converted to will determine the type of converter needed. The more complex converters will have outputs for S Video, Composite, as well as the classic RCA video and audio output cables from the device.

Step 2 – Connect the video converter to a power source (such as a wall socket or power strip).

Step 3 – Connect the HDMI cable from the device that only produces HDMI output to the HDMI input plug on the converter.

Step 4 – Connect the Red and White audio cables to the RCA audio outputs on the converter then connect to the television.

Step 5 – Connect the Yellow video cable from the video converter output to the tv’s video input.

Step 6 – Change the television channel to the one that the converter requires (normally channel 3 or 4 for televisions that do not support the “input” function) or press the “Input” button on the remote control (if supported) to view the video from the device on the television.

HD surveillance users can reduce bandwidth

HD Surveillance users can Reduce Bandwidth

When organizations are considering the switch from analogue systems to network-based HD solutions, there's often the perception that bandwidth levels will increase significantly, as will the costs associated with expanding network and storage capabilities. While these concerns do have merit, the truth is that HD video surveillance need not take up as much bandwidth and storage space as you might expect, so long as the right tools are in place.

When it comes down to managing a company’s network, IT professionals are generally cautious and strategic with how they allocate it. With only a modest percentage of the bandwidth usually reserved for video surveillance, the last thing an IT manager wants is video footage - particularly if it’s in HD - slowing down the entire network and taking up too much storage space.

The perception of high-definition video surveillance by those new to using it, is that HD surveillance takes up too much bandwidth and storage space and that you will have to pay a lot of money to expand your network and storage capacity in order to accommodate it. But HD video surveillance does not take up as much bandwidth and storage space as you might expect. Especially with technology advancing, surveillance cameras and systems are getting smarter and more adaptable to a variety of network and storage circumstances. Here are four things you can do to your HD cameras and system right away to lower bandwidth usage.

Selecting the right compression format

Getting familiar with your camera settings will allow you to maximize your image output without compromising storage space. Choose a compression format that best suits your needs. If you are looking to increase your storage, you may want to go with the h.264 compression format. Most HD video surveillance users are partial to H.264 over M-JPEG because of the way the compression works. It doesn’t capture each frame as a separate entity like M-JPEG. The video stream is composed of a reference frame, called an Index (I) Frame, and then changing areas of the image in subsequent frames, called Partial (P) Frames. The end result is a collection of I Frames and P Frames in an ordered pattern that is configurable on most cameras (for example: 1 I Frame every 30 Frames). This results in less “full" images (I Frames) and using less bandwidth and storage space without sacrificing image detail.

Use the appropriate resolution

Pick the camera that provides the least resolution that you need to get the job done. Why choose a 2 MP, when a 1 MP can do the job? Higher resolution generally means more bandwidth, which requires more storage. Obviously in a parking lot or areas where you are trying to cover a large area in high detail, a high megapixel camera is necessary. But if you are just monitoring a hallway or door, it makes sense to use an HD camera that can capture the detail you want at the lowest possible resolution.

Lower your frames per second

You are not shooting a movie, so there is no need to see 50 frames per second. Most people in the security industry use 5-7 frames per second, which in most cases, is going to show you everything you need to see evidence-wise and will be able to drop your bandwidth by a decent amount of megabits.

Recording on motion

Aside from adjusting camera settings to lower bandwidth, it is also a smart idea to configure your server to do event-based recordings. As an example, if you set up your servers to only record on motion events, then you will only capture footage whenever there is activity in the area that you are monitoring. The cameras are most likely always streaming to the server for live video, but with motion based recording they just wouldn’t be saving the data to the storage.

Strong Access Code Recommendations

If the site is using magnetic swipe cards or proximity cards, the code will already be programmed on the card. If the site is using individual access codes for each user, strong codes are important for the security of the site. If a user's access code is compromised, a thief can use the code to gain illicit access to the site. This can mean monetary losses to a site.

1.    Codes should be unique for each user. Even if multiple users share the same unit (such as spouses or employees of a company), each user should have their own code to identify their activity on the site. Remind your users not to share their codes with anyone and that they are responsible for all activity that occurs with their code.

2.    Codes should always be more than four digits in length to prevent them from being easily guessed. Seven to ten digits make the best codes.

3.    Codes should not proceed in numeric order. This helps prevent customers from guessing other codes. If you are pre assigning codes, count by threes or sevens to help prevent this. If you are ordering swipe cards or proximity cards, request this.

4.    Never use Social Security Numbers for codes.

5.    Good codes are random enough to prevent guessing but still easy for users to remember. Try using the unit number plus the user's telephone number. This will generally give a long enough code that will be unique to each customer but is still easy to remember. For example, a customer in unit C130 whose home phone number is (33) 2541-1513 could be assigned 3325411513 as their ten digit code.

6.    Manager codes, employee codes, and customer codes should all be different lengths. This helps prevent someone from guessing a code used by someone with a higher access level. For example, you could assign all managers eight digit codes, all employees nine digit codes, and all users ten digit codes. If you are ordering swipe cards or proximity cards, request separate number series for employees, managers, and users.

7.    If you suspect a code is being used by someone other than the assigned user or if a user reports their card lost or stolen, go into the Setup Cards function by pressing F3. Select the code from the list and edit it. In step 2 of 2, click Card was Reported Lost. Contact the user and assign them a new code. When someone tries to use this code again, it will show as Lost or Stolen on the event log.

8.    Use the Bad Attempts setting. Go to the Setup screen in StorLogix and select Setup AI Devices. Make sure the advanced options are clicked and go to step 5 of 6 and set the Bad Attempts Limit. Generally this should be set between 3 and 5. This is the number of wrong codes that can be entered before the system locks up to prevent someone from entering random codes trying to guess a good code.  

Stop Unwanted Visitor in the School premises

School Security – Stop Unwanted Visitor in the premises

The security of any organization is the major concern, whether it be a corporate house, a manufacturing unit or schools and colleges. We have previously discussed about the security concern of the corporate houses and other work places. But through this write-up I will focus light upon the security concern of Schools and colleges. Recent happening across the globe have sent a thrill for the security of school going kids. So the safety of kids is more important for any authority. Thus, in the course of providing security for kids or students, technologically updated security system is a must.

The major components of security for schools and colleges are security cameras for video surveillance, access control of the movements of the visitors, and visitor management system for maintaining the records.

Video Surveillance: - Probably one of the most important aspect of the security of schools and colleges is a video surveillance through security cameras. The reason for this is simple, as to keep an eye at each and every corner of the campus through cameras to know what is happening on the campus ground or any classroom or in corridors. Security cameras prevent vandalism, bullying, criminal activity and sexual predators. With surveillance you will always have a record of near school property or any unwanted movements. Video surveillance will help to protect the facility from potential lawsuits as well as protect students from intruders. This whole thing is impossible if done physically.

Access Control Solution: - Another crucial and important feature that plays an important role in the security of the school premises. It does not require anyone to keep waltzing into the facility as access control lets you monitor who comes and goes. You can also do the setting in the installed access control with pin and password, which can restrict the unwanted access in the premises. It helps to reduce or stop the unauthorized movements in the arena of school. Also, you can manage the groups accordingly restricting the movement in unauthorized zones. Access Control Solution will add a deepness in the security.

Visitor Management System: - Each visitor can be managed through visitor management system, keeping his/her complete records, including the concerned person or student with whom they have to meet. As this software generates the gate pass of the visitor with his/her photograph. Until and unless all these processes are not done, the access cannot be granted to enter the premises. This helps a lot to stop the unwanted movements and entry of intruders.

The safety of school kids is the major concern for any authority or school administration. So keeping these things in mind, one should look after the security of school premises. Though this one time investment can be benefiting many lives, as nothing is precious than LIFE.

ONVIF and PSIA Standards in Video Surveillance

ONVIF and PSIA Standards in Video Surveillance 

We talk to two of the biggest interface standards organizations in surveillance – ONVIF and PSIA.

ONVIF is a global and open industry forum with the goal to facilitate the development and use of a global open standard for the interface of physical IP-based security products. Or in other words, to create a standard for how IP products within video surveillance and other physical security areas can communicate with each other.

It was officially incorporated as a non-profit, 501(c)6 Delaware corporation on November 25, 2008. ONVIF membership is open to manufacturers, software developers, consultants, system integrators, end-users and other interest groups that wish to participate in the activities of ONVIF. The ONVIF specification aims to achieve interoperability between network video products regardless of manufacturer.

It’s all very well running your security across an IP network, but if your recording device won’t talk to your PTZ camera, you are not going to get very far. Over the last decade, the security industry has spent a lot of time talking up the benefits of IP-based surveillance systems, and end-users have been bombarded with literature and sales pitches on the subject.

It soon become clear in an industry that was raving about the endless opportunities for security on the network that manufactures would have to become a little less proprietary in their dealings with their customers. In short, it was no longer fair to deny end-users the ability to choose whatever camera they wanted and whatever DVR they wanted on their network. They were, after all, used to IT systems that interfaced. It was time for the security industry to realise it had to be more open as well.

Two organizations that have been at the forefront of the drive towards open standards in the industry are ONVIF and PSIA.

ONVIF: Open Network Video Interface Forum

The cornerstones of ONVIF are:

Standardization of communication between network video devices

Interoperability between network video products regardless of manufacturer

Open to all companies and organizations Members

ONVIF was set up in 2008 by Axis, Bosch, and Sony. A non-profit organization, its aims are to create standardization in the industry to aid communication between various vendors’ video devices and then interoperability between those devices and others on the network, regardless of manufacturer. 300 member companies since its founding in 2008. The list of participating members includes major manufacturers like Vivotek, Arecont Vision, and Milestone Systems.

In December 2009 ONVIF’s member base had grown to 127 members. This comprised 14 full members, 15 contributing members and 98 user members. In December 2010, the forum had more than 250 members and more than 600 conformant products on the market.

ONVIF now has 480 members and as of mid-October 2014 has nearly 2040 products that conform to its Profile S specification, which handles video and audio streaming. The total number of products that meet the ONVIF core specification has reached well over 4,000.

In order to be ONVIF conformant, manufacturers use the test tools developed by ONVIF to meet the requirements of its core specification. Only manufacturers whose products have met the requirements of the test tools can submit a test report and a Declaration of Conformity signed by the manufacturer.

The core ONVIF specification, which was launched in November 2008, aimed to define a common protocol for the exchange of data between network video devices. Since then it has extended its scope to include access control products and also has developed specialist profiles for specific categories. The idea behind the profile was to help end-users identify which version of the ONVIF specification the products they were interested in conformed to, making it easier to determine compatibilities between conformant products and specific interoperability features.

There are now three ONVIF profiles, S, G, and C. Profile S looks at the common functionalities of IP video systems, Profile G addresses storage and recording functionalities and Profile C, the integration of IP-based security and safety devices, including access control units. Profile C is expected to be released in early 2014.

Per Bjorkdahl, chair of ONVIF’s steering committee, told us:

The profile concept is a way for end users and systems designers to identify more easily what products will work together without needing an in depth technical knowledge of the specification or having to keep current on each new release.

Profiles group together common sets of features and functionalities, so when two products — for example an IP camera and NVR — both bear the Profile S mark for video and audio streaming, they will work together.

The organisation has been making a concerted effort to broaden its security scope after some criticism that it was too focused on video. Bjorkdahl continues:

From the beginning, ONVIF’s focus was video because we knew we could get the proper feedback from the marketplace and because the need for standards and interoperability on the network video side was so acute. But ONVIF recognized from the start the need for specifications in other industry segments.

Its next area of concentration he says could be new additions in the physical access control area or a new profile for intruder alarms.

The benefits of an open standard for network video should include:

Interoperability – products from various manufacturers can be used in the same systems and “speak the same language”.

Flexibility – end-users and integrators are not locked within proprietary solutions based on technology choices of individual manufacturers.

Future-proof – standards ensure that there are interoperable products on the market, no matter what happens to individual companies.

Quality – when a product conforms to a standard, the market knows what to expect from that product.

ONVIF Specification: 

The ONVIF Core Specification aims to standardize the network interface (on the network layer) of network video products. It defines a network video communication framework based on relevant IETF and Web Services standards including security and IP configuration requirements. The following areas are covered by the Core Specification version 1.0:

IP configuration

Device discovery

Device management

Media configuration

Real time viewing

Event handling

PTZ camera control

Video analytics

Security

ONVIF utilizes IT industry technologies including SOAP, RTP, and Motion JPEG, MPEG-4, and H.264 video codecs. Later releases of the ONVIF specification (version 2.0) also covers storage and additional aspects of analytics.

Drawbacks of ONVIF:

Onvif is a new standard and as such has issues. From our experience there are 2 combining factors contribute to the reliability of an Onvif based CCTV system and they are.

How good a camera manufactures implementation of the Onvif protocol is.

How well VMS manufacturer ensure the quality of the marriage between their implementation of Onvif protocol and each camera manfacturers.

Some IP camera features and enhancements may not be available when using a VMS that exclusively supports the ONVIF standard. To take advantage of some of these features you may need to use the manufacturers own proprietary VMS (Video Management System) application or choose a VMS that supports these enhancements.

The profiles tested were:

Profile S, for IP-based video systems;

Profile C for IP-based access control;

Profile G for edge storage and retrieval as well as the upcoming

Profile Q for improved connectivity.

Arguments Against Video Surveillance

As the use of CCTV cameras increases across the globe, so does the debate over their numbers and motives. In a previous post, Arguments for Video Surveillance, we looked at four arguments for video surveillance. These arguments included peace of mind, loss prevention, crime deterrent, and crime solving.

But what about the other side of the fence? The ACLU has an entire Web site, You Are Being Watched, devoted to the “high costs of camera surveillance systems, both in terms of money and civil liberties,” and there are a large number of individuals and other groups out there that oppose “big brother” watching our every move.

So, what are some of the arguments against the use of CCTV surveillance systems?

1. Invasion of Privacy – This is the most common argument against surveillance systems. While video surveillance is more commonly accepted in public areas, this sentiment comes into play with the use of covert and hidden cameras in almost every case.
2. Mistrust – The use of security cameras in your home or business can make its occupants feel mistrusted. If your family members or employees are under constant surveillance, there is likely to be hostility and animosity in the air.
3. Not Proven Effective – Studies done in California and London have found that security cameras had little to no effect on reducing the crime rate. With an increase in the sheer number of cameras in many large cities, many replacing human security guards, this is a strong argument that will be the main target of many opposing groups.
4. Misuse and Abuse – The footage captured by CCTV cameras becomes susceptible to abuse and misuse by those who have access to it. For instance, the footage can be used to discriminate against people and for voyeurism. In the age of the internet, this is another huge deal, as can be seen by all of the “hilarious” YouTube videos out there. I doubt the subjects would find most of them as funny.

All of these reasons are valid arguments against CCTV surveillance. There are many cities and countries that have massive surveillance systems, and we will likely see a large increase in public monitoring in the near future, so the more the public knows about the industry and their rights, etc, the more everyone can prepare for when it happens in your little corner of the globe.

Do you have any additional arguments against the use of security camera systems? What are your thoughts? Will you fight them, or open your “public” life up willingly to being observed? Let us know – we’d love to hear from you.

Differences H.265 and H.264

Differences between H.265 and H.264

A codec is an encoder and a decoder. An encoder compresses audio or video so it takes up less disk space. A decoder extracts audio or video information from the compressed file. Video and audio compression is a complex technical process, but the basic aim of a codec is quite straightforward:

(a) Reduce the size of the compressed media file as much as possible, but...(b) Keep the quality of the decoded audio and video as good as possible.

What is H.264?
H264 (aka MPEG-4 AVC) is currently a mainstream video compression format. It is widely used in Blu-ray discs, internet sources like videos in YouTube and iTunes Store, web software, and also HDTV broadcasts over terrestrial, cable and satellite.

What is H.265?

H.265 (also known as HEVC, short for High Efficiency Video Coding, developed by the Joint Collaborative Team on Video Coding (JCT-VC)) is a video compression standard whose predecessor is H.264/MPEG-4 AVC. H.265 HEVC ensures to deliver video quality identical to H.264 AVC at only half the bit rate, including better compression, delicate image and bandwidth saving. It Support up to 8K, Support up to 300 fps. It is likely to implement Ultra HD, 2K, 4K for Broadcast and Online (OTT).

H.265 vs H.264: Differences between H.265 and H.264

In general, H.265 has several big advantages over H.264, including better compression, delicate image and bandwidth saving. For more detailed differences, please read H.265 vs H.264 comparison table.

4 pcs 2MP IP cameras for 1 month, stream: 4096Kbps. 
H.264 IP camera need 42G×4×30=5T=1×3T+1×2T, so need 1 pc 3T and 1pc 2T HDD. 
H.265 IP camera need 21G×4×30=2.5T, so need 1 pc 3T HDD only, save at least 1 pc 2T HDD cost. 

Configuring an Access Point as a Wireless Bridge

Configuring an Access Point as a Wireless Bridge

Linksys Wireless-G Access Points can be configured as an Access Point, Access Point Client, Wireless Repeater, and Wireless Bridge. The Wireless Bridge mode will turn the access point into a wireless bridge. Wireless clients will not be able to connect to the access point in this mode. 

NOTE: When an access point is configured as a wireless bridge, it will link a wireless network to a wired network allowing you to bridge two networks with different infrastructure.

NOTE: When the WAP54G access point is set to wireless bridge mode, it will only communicate with another Linksys Wireless-G Access Point (WAP54G).  

To configure an access point as a wireless bridge, you need to perform three steps:

Changing the LAN IP Address of the Wireless Bridge

After configuring the access point as a wireless bridge, change its LAN IP address to avoid IP address conflict.

You need an Access Control Systems

Do you need an Access Control Systems?

Access control security systems are designed to restrict physical entry to only users with authorization. Many organizations, governmental and private, have started adopting access control security systems for physical entry into their facilities. Whether it is a simple non intelligent access control system like a punching in a password, or advanced biometric systems that scan and permit entry very specifically, there are many advantages to employing these security systems.
It is important for businesses of every size to keep important data and remove threats. All businesses acknowledge this basic security concern by placing locks on the door and giving keys to employees that need to access these locks. If you answer yes to any of the following questions, you may need access control systems:

• • Is a lost or stolen key a security threat to your business?
  • Time Based Control for Security Systems
  • Do you need different access for different employees and clients?
  • Would it be really beneficial to restrict access based on time or day?
  • Do you need a record of people’s “comings and goings?
  • Could your employees/clients be more secure?
  • Reduced Requirement for Manpower
  • Biometric Systems

Benefits of access control systems

The benefits of access control systems are thus many:

• Audit trail – With access control systems, you will have a record of every opening and attempted opening of each door or specific area. The audit trail can be valuable in resolving employee issues.
• Time/day restrictions – Do you have certain employees that should only be there at certain times and days. An access control system make more sense to control their access than to give them a key that allows access at any time or day.
• Lost or stolen keys – When keys are lost or stolen, it is an expensive process for a business to completely rekey each door. Access control systems allow you to remove access by deactivating the I.D. badges or other security credentials.
• Remote access control – Many access control systems allow you to control of all of the business’ locks from one main system. With access control systems, you can easily and quickly lock down your businesses in an emergency as well as add and remove credentials.

Design 1:

Design 2: Single Door

Design 3: 4-Door single controller.

Design 4: New Concept, PoE Based

Design 5: SYRiS Product with SQL Database, Multi-location. One SY230NT Controller can controll 4nos of Door. Practically i do many projects with this.

How the Access Control System WorksØ  The typical access control system consists of a card/ pin reader, electromagnetic lock or door strike, power supply system and a push button.
Ø  The valid and authorized card user must present the card to the security system.
Ø  Upon verification by the reader, the locking system will be de-energized and the door can be pushed open.
Ø  To exit the premises, the person will have to press a door lock release switch and the system will release the lock.
Ø  A power back up is also installed while fitting in the access control system.
Ø  A break glass is also incorporated in case of emergency.
