Maintenance of the Security Bollard

Maintenance of the Security Bollard 

A high security bollard or entrance control bollard system is designed to deter or completely stop unauthorised entrants, assets or vehicles whilst enforcing the use of an access control system to ensure the ‘one token one person’ rule applies. Bollards are used to protect areas that are either completely pedestrianised, or to restrict vehicle access. Bollards also act as a great security measure for businesses and shop fronts too. Bollards are made from sturdy materials, they can sometimes be damaged or develop wear and tear over time.

The weather can have a large impact on the condition of a bollard. Going from hot to freezing temperatures can cause cracks over time. Likewise, long periods of heavy rain over the years can result in imperfections, especially where wooden bollards are concerned. That’s why it’s important to check your bollards regularly, especially if there has been an extreme change in weather. Metal bollards are less susceptible to weather damage, but over the years it may create some issues.

Bollards are usually found next to roads, or within car parks, and this means it’s not unlikely that one or two will come in contact with a vehicle. Bumps and scratches can occur, and over time this may lead to permanent damage to your bollards. A CCTV system can help to document any accidents around your perimeter and to check the severity of the damage. If any serious damage is caused, it is always best to replace the bollard.

Learning to check your bollards for damage is a great way to improve their overall maintenance. Regularly inspecting them for cracks and breaks means that they can be fixed quicker and no lasting damage will occur. If you have had your bollards for a long time, the exposure to various weather conditions may have caused them to rust or for parts to loosen. With this in mind, make sure to check them frequently. Dirt can also build-up on bollards, so giving them a quick clean every now and then will improve their performance greatly.

Safety Instructions

All personnel who are applicable for the operation of the bollard, including back up personnel, must be thoroughly familiar with the operation and safety regulations.

Any maintenance and repairs must only be implemented by certified technical personnel.

No persons and/or vehicles are allowed into the area over the blocking element when the bollard is functional.

The closing element must be extended early enough that approaching vehicles can still stop in time.

If the bollard functions are activated with neglect to the afore mentioned points the manufacturer cannot be held liable for any damages that may result to any person and/or property.

Before the maintenance work can begin all safety precautions must be adhered.

Monthly Maintenance by the Operating Personnel

After the control the stated changements in comparison to the original condition should be eliminated by corresponding counter measures.

The following points are to be visually examined:

Barrier bollard

1) Clean any contamination on the annular gap between the bollard and the cover of the standpipe

2) Check the extended blocking element for damages, e.g. impact, allow damage repair

3) Check for faultless bollard movement and pay attention to any unusual noises

Drive Unit

1) Check the hydraulic screws, oil tank and hydraulic units for leakage

2) Check the intactness of the hydraulic hoses

3) Check the oil level (level should be within the mark)

4) Check the intactness of the cover seals

First maintenance service by a machine expert

The first maintenance service should be made by a machine expert within the 1 quarter after the installation.

A. Barrier bollard

a) Clean bollard completely from dirt

b) Screw-out bollard cover and examine fixation of the hydraulic cylinder

c) Examine the piston rod and the hose connections of the cylinder on leakages through light beam of a pocket lamp.

d) Examine speed position above one -way restrictor and adjust once or if necessary the approximate direct running of the bollard running-out movement.

Bollard housing

a) Screw-off cover of the bollard housing and examine fix position of the proximity switch.

b) Clean cover and inner space of the bollard housing and clean if achievable from dirt.

c) Note, if penetrated surface water has flown above the drain channel, eliminate eventual obstructions. There should not be water in the bollard housing.

d) Note purification degree on the bottom of the bollard housing. At bigger dirt, especially in the construction phase.

Drive unit

a) Clean drive unit completely from dust and dirt.

b) Examine adjustment of the pressure limit valve for the operation pressure Manometer indication until. 50-60 bar allowed. 

Semi-Annual maintenance service by a machine expert

The semi-annual maintenance is to be performed by a machine specialist. It covers the visual examination as described under Point 1 and the following additional work:

Blocking Element

a) Clean the entire blocking element

b) Unscrew the blocking element cover and check the hydraulic cylinder mounting as well as checking the tightness of the electrical limit switches

c) Check the piston rods and hydraulic cylinder hose connections for leakage (use a torch / flashlight)

d) Check the approximate synchronisation of the bollard drive-out movement in multiple systems, if necessarily adjust the speed at the one-way restrictor.

Standpipe

a) Clean cover and interior, within reach, of any contamination

b) Check the drainage connection, if necessary remove any blockage

c) Determine the degree of pollution on the bottom of the standpipe. With large soil accumulation, particularly in the building phase, cleaning may be necessary.

Drive Unit

a) Clean the dust and dirt from the entire hydraulic unit.

b) Check the operating pressure, if necessary adjust the pressure release valve (approx. 50-60 bar)

Extensive maintenance service by a machine expert

The extensive maintenance service is after 1000 operation hours, but at least each 2 year. Additionally to the first maintenance service the following works should be made.

a) Examination of all functional components, combinations and screwing on integrity and fix position.

b) Exchange of the hydraulic liquid. Open filler cap and guide the hydraulic liquid into the sanitation container.

c) Use the unused hydraulic liquid, of the type of the first filling, to be bought from the bollard manufacturer.

d) Make functional test and if necessary, proceed to adjustment.

e) Examination of the control by an expert. Examine condition of the control and perfect working procedure of the electrical components.

Maintenance of security levels CCTV Cameras

Maintenance of security levels at Construction sites through CCTV Cameras! 

There is no sense in denying what is apparent, but a construction site is an area that has constant traffic all day long and sometimes during the night as well. Most managers are often forced to increase productivity levels at the site to meet the requirements of the building owners.

However while completing the construction job on time might be an excellent idea, keeping track of all the activities that occur at the site often provides to be challenging task especially for project managers.

More so, security companies often find it difficult to come up with genuine evidence to back criminal offenses that may occur at the given construction site. With the advent of special technological contrivances such as CCTV security system, managing a construction site has become that much more simple.

See average Number of Security Cameras below:

Benefits of Installing CCTV Systems:-

1. Monitor construction workers

One important benefit of installing CCTV systems at the construction site is that it allows the project managers to have a better view of the employees` activities. To be specific, the construction site is often a beehive of activity, which can sometimes pose a challenge for managers who are supposed to account for everything.

In the past, the managers would have to rely on unreliable reports from their subordinates or perhaps spend hours going around the entire site to determine the worker’s activities. This was a highly unreliable method, and CCTV cameras provide a better solution for such a complication.

In fact, construction managers can monitor their employees work rate levels by watching recorded or the live footage that is relayed by the cameras.

2. Evaluating the site

Besides that, another important benefit of installing these types of cameras at the constructions site is that it provides the managers with a better option for viewing the progress of the entire site. It’s important to note that CCTV footage along with individual devices such as drones are often used to determine the progress of a given construction project. Managing the site is highly important since it allows the managers to determine whether additional resources such as skilled labor or resources are needed to complete the project.

While the manager might still have to visit the site for first-hand observation, the CCTV cameras are also convenient since they provide footage of how the events at the site have been unfolding.

3. Determining resource usage

More importantly, the CCTV systems can also be used to determine the level of resource usage at the construction site. This is because the level of activity at the site of often so high such that the construction manager cannot be able to account for resource usage at the scene fully. Some of the resources that need monitoring include cement, hardware tools and employee gear amongst many others.

With this types of systems, the manager can easily determine where any inconsistencies or perhaps where there was any illegal activity occurring at the site and therefore deal with it as soon as possible. As a result, the manager is better at accounting for resource usage or perhaps identifying any project setbacks on time.

4. Help improve security at the site

One of the biggest hindrances that most constructions projects face is the maintenance of security levels at the site, especially when no one is watching or perhaps when the site has been dormant for a while. For security companies, the footage can be used to determine any inconsistencies or perhaps any illegal activities that may be taking part at the site.

The footage always provides an excellent perspective when it comes to settling security complications in criminal cases. By installing CCTV security systems at the scene, construction managers can determine any form of illegal activities or perhaps the theft of costly resources that are used for the completion of construction projects.

While the presence of security cameras is often enough to deter the vast majority of would-be thieves and vandals, you will have access to the video evidence required for successful prosecution should trespassers ever infiltrate your site. Not only are CCTV cameras more cost-effective security solution than man guarding, but you can also access live footage around the clock remotely via the internet should you ever wish to.

Given all these points, when it comes to managing an entire construction project, there is barely any space for poor decision making or perhaps insufficient improvisation. It’s imperative that you take the time to make an informed decision for the development of your project and this often includes settling for the superior benefits of CCTV systems. Although these types of security systems might cost a significant amount to install, they are crucial towards the completion of the entire project are therefore a feasible investment for any given construction project.

Below you'll find a range of security cameras for construction sites with different features. It's also possible to purchase a combination of cameras to suit different construction site needs.

Sliding Gates vs Swinging Gates

Sliding Gates vs Swinging Gates 

Gates add value and security to your property. They’re also your main control for access to who goes in and out and serve as a point of entry to your home, business, and land.

The first electric gates were invented in 1881, and the benefits of the automated gates have also evolved, catering the needs of each generation of homeowners and business owners to increase the security and the convenience of opening and closing an entry point structure. Automatic gate systems use electric motors to open and close gates through the use of a transmitter.

When it comes to perimeter defences, the first thing that will likely jump to mind is the image of a security gate, and rightly so. Security gates are often the first line of defence for many businesses when it comes to keeping intruders away, establishing a strong perimeter, and sending out a message to criminals.

However, when planning defences for a site, or considering upgrading your existing measures, it’s important to think carefully about your needs and your site capabilities. Let’s take a look at two of the most popular options of gates and how they compare.

Swinging Gates

Swinging Gates are an excellent option for many businesses. As the name suggests they swing open and shut in a wide arc. Often priced cheaper than sliding gates, they typically don’t include motors or electronics. Swinging gates don’t require concrete work or steel beams, they are low maintenance and make little noise during operation. This means that they are well-suited to isolated or rural sites, or large expansive sites where access to the grid is more limited.

If considering swinging gates as a solution for your site, you should think carefully about the available space on your premises. Swinging gates need enough space to open internally and externally in a wide arc and so might not be suitable for some sites where space is at a premium. They might also be less suited if you have particular needs for high-tech upgrades such as access control equipment or other electronic support.

Sliding Gates

If you are looking for gates at a site where space is less readily available then sliding gates may be a more sensible solution. Rather than opening and closing in an arc, sliding gates slide in and out along a track or trackless cantilever system, which both employ less of a footprint.

Sliding gates are often seen in more commercially-led settings, entrances, and residential driveways. They can be employed on rough ground and even on sloping ground if required. They are a good choice if you operate in a setting that has high-wind speeds and other unpredictable weather factors.

Unlike swing gates, sliding gates can be upgraded with access control equipment such as electronic keys, cards, fingerprint biometric readers and intercoms. These additions will always make a site more secure, however, they do come with added costs.

Confuse as to what type of gate to choose? You might wanna consider these insights.

The main advantages of sliding gates are:
• They aren’t affected by wind
• They don’t take up space on your driveway when opening and closing
• The gate can slide from the left or the right, depending on where you have space
• If you don’t have the space required, there are other types of sliding gates, such as telescopic sliding gates or bi-parting sliding gates, that take up less space.

The advantages of double swing gates:
• A double swing gate takes up less area when in operation
• They are less affected by wind
• As the weight is distributed between two gates, there is less stress on the swing gate motor, posts, and hinges.

The advantages of single swing gates:
• There are only one gate and one set of hardware to automate it, so you’re up for less installation and maintenance (assuming you purchase quality parts, as the load on all parts will be greater).

General swing gate fitting information:

• With swing gates, there are two options as to where to install the hinge. You can install the swing gate opener on the sides of your posts parallel to each other facing inwards, or on the side that faces into your property. If you do the latter, the fixings are hidden by the posts and the swing gates take up less space. 
• If your driveway slopes up from the road and there’s no room for a sliding gate, you can install a swing gate that opens outward. Just make sure it doesn’t interfere with public spaces.

Security Integration management systems

Security Integration Management Systems 

Security systems are changing at an ever-increasing pace and are becoming standard Information Technology (IT) products running over a Local Area Network (LAN) or Wide Area Network (WAN). As a result of using standard protocols such as Transmission Control Protocol/Internet Protocol (TCP/IP), the manufacturers to develop new generations of integrated systems. These systems are called System Integration as they bring together the management of all aspects of an organisation’s security. In recent years, the market for security equipment has realized the immense merits of integrating different components in a security system. However, true integration may be offered by all the manufacturers in the field today. A truly integrated security system combines the various components and yet they are all part of a more sophisticated and bigger system.

Some people use the term 'integrated' to describe a multiplexer combining full screen and multi screen images. Or a control desk containing an integrated intruder alarm PC, an integrated fence alarm PC and an integrated CCTV PC sitting next to one another. This is not true integration.

It is possible to integrate components like a public address system, CCTV, fence alarms, intruder alarms, fire alarms (life safety) and access control system within a single system. The system can be multi-station networks or even a single PC. All these components should interact with one another as a single entity. For example, whenever the fire alarm gets activated, the screen of the Visual Display Unit should pop up a new text window where detailed instruction should be given on what to do next. Simultaneously, the integrated system may release the doors meant for fire exit and display those CCTV cameras, through which the operator can view the affected area so that the operator in question can engage in a communication with the other staff and do not have to take the help of any public address system.

It is not always necessary to purchase all of the components of a system from one supplier. Manufacturers of Security Management Systems realise that the customer wants choice and will often link to components from other specialist manufacturers. Many manufacturers provide integration modules and protocols such as BACnet and OPC, and data integration methodologies such as eXtensible Markup Language (XML), ActiveX and others, which can in theory link to almost any business system. You will need to talk to individual suppliers to discover what development tools such as Software Development Kits (SDK) and Application Programming Interfaces (API) are available for integrating systems. Yes, the system should be able to function with the help of a battery backup though the duration of this backup time may vary according to the type of panels used within it. In my experience this has not been an issue, but some manufacturers are very cautious to whom they release this information. If you are a competitor it is almost impossible.

Even when protocol has been received 90% of the time it is either incorrect, incomplete or even misleading! It is essential to test product before installation, I know it is an old fashioned idea but it is really nice to see the system actually working.

Opportunities of System integration

There are a number of advantages to be gained in both the security and commercial aspects of designing and adopting an integrated system. This section lists some of the advantages that may be considered when combining separate systems into an integrated solution.

Access Control Systems (ACS)

Access Control is typically specified to provide protection to both property and employees. Generally it is thought of in terms of managing doors. However, it often extends to public areas when coupled with turnstiles, gates and barriers, or highly sensitive areas when coupled with biometrics.  If the access control and intruder alarm systems are linked together, the access control system can be programmed to automatically change, based on the type of alarm that sounds. By integrating Access Control with other systems many advantages may be realized. For example:

Fire Alarm mustering – know where your employees are at a given time.

Know which doors / areas employees are entering, or trying to enter.

Link CCTV images with access control events.

Link Time & Attendance monitoring using the same badge / token software.

Link Visitor Monitoring with Access Control & CCTV using badge / token software.

Increase security through systems such as dual card access or access using a biometric technology.

Intruder & Hold up alarm system control functions can be managed by the Access Control system.

Logical Security

Logical access control is the brother of physical access control but is often limited to secure PC logon. Integrating these two elements can significantly increase your security. For instance, you can restrict PC access to only those who have a smart card and use this to logon to your IT network. Alternatively, you can inhibit network logon if the person is not in the building, further enhancing your security.

One example is to use the CCTV system and access system to monitor and lock doors during a denial of service (DOS) attack at the same time as sending a message to the security guards. Quite often physical and logical attacks go hand in hand.

Time & Attendance (TA) monitoring

The same badge/token used to identify a person in Access Control can register them on and off work with Time & Attendance monitoring. Also as more integrated software systems become available, use of the same software to handle Access Control, Time & Attendance and Visitor Monitoring can be achieved. Remember however, that just because a person went through an Access Control door does not mean they are registered for work, especially under Working Time Directive (WTD) rules. You will need separate T&A clocking stations, albeit on the same network, to monitor working hours and software to calculate employee hours, monitor absences and WTD hours and infringements.

Human Resources (HR) / Payroll

Why enter data twice? When a new employee joins a company his personnel details are often entered into both the appropriate HR system and then again into the security system. By integrating these two systems, a subset of the employee data can automatically be transferred into the Access Control System when an employee joins. Alternatively, when an employee leaves, his rights can be automatically deleted from the Access Control System, again reducing effort and increasing security.

CCTV Systems

By integrating CCTV and other systems such as Access Control, the benefits of more than one system can be coupled to provide a more efficient and usable solution for the end user. IP camera can be integrated with Motion Sensor not only that If IP camera has I/O port you can integrate with other systems like, Hooter, Auto dialer etc. Through Video management intelligent Software you can get face reorganization, license plate reorganization etc.  For example:

Live camera views can be integrated with the Access Control Software, equally Access Control or other data can be integrated with the CCTV system.

Access Control and other security detection systems can initiate pre and post-event video recording, linking the video recording with the event information. This makes searching for events on the DVR/NVR more effective as only the event needs to be searched, for example ‘Door forced – Stores Door’ or ‘Zone 1 – Perimeter breached.’

Track individuals and record their access details against the recording to track suspect users or stolen card users.

Initiate camera presets when specific pre-determined events occur, e.g. when entering a room in a bank, switch the camera to zoom into the door to identify the individual.

Use CCTV with Time & Attendance system to detect / eradicate ‘buddy-clocking’, a practice where employees clock each other on and off work.

Intruder Alarms Systems (IAS)

By integrating intruder with other systems, the benefits of more than one system can be coupled to provide a more efficient and usable solution for the end user. For example:

Set / unset the intruder system using an access reader. No need to use the intruder keypad.

No entry delay time if main door forced. The entry timer is bypassed thus providing an instant alarm.

Disabling of access readers when the intruder system is in the armed state, to prevent false alarms due to unauthorised entry into an armed area.

Using an occupancy count from another system, the Intruder & Hold Up Alarm system can be notified that there may be persons present in the building when the system is being set.

External Perimeter Detection

One of the fundamental objectives of a security system is to provide protection at the outermost perimeter of a property. A perimeter intruder detection system can be used, linked with CCTV to provide early warnings and increased security through verification in the event of a breach. For example, external doors could be automatically locked if the perimeter system detects an abnormal event.

Fire Detection & Alarm Systems

Fire protection / Detection systems have traditionally been isolated from other building management and security systems. By integrating fire with other systems, the benefits of more than one system can be coupled to provide a more efficient and usable solution for the end user. For example:

In the event of a fire all emergency exit doors on the fire escape route need to be automatically released from an electrical point of view, but physical quick release locks may be in place to maintain security and still allow people to escape. It is common practice to install a relay in series with the electric locking mechanism controlled by the fire panel. An alternative is to feed a fire input into the Access Control System, which then automatically releases the appropriate electric locking mechanisms. The proposed link between the Access Control System and the fire system should be evaluated as part of the fire risk assessment.

In addition to providing hardware control during a fire situation, it may be necessary to provide a ‘roll call’ or ‘muster’ report to list all people in the building at the time of the fire alarm.

PA system (PAS)

In general IP paging and intercom systems are used to direct people in emergencies, control doors and control other situations such as crowd control. However, integrating such systems with others leaves the door open to new uses and can push a technology to its full potential. For example, integrating a campus’ PA system with security systems such as video surveillance could give campus security operators more control over emergency communication. Paging can be integrated with IP camera systems. Small amplifiers are used to power speakers that can be used with the cameras.

It is also important that the video management software (VMS) supports the audio. Some VMS will provide an alert if they detect a button activation from the IP camera. The VMS then allows the security person to see what is happening and then talk to the person near the IP camera.

The Digital Acoustic intercom system is independent of the VMS and uses its own Windows paging software. In this case, the security person can receive an alert from an intercom and be notified on their Windows computer. The software also allows the security person to view a nearby IP camera. This is not quite as integrated as the first method, but can provide additional security.

PA Controller should be integrate with Fire Detection system, in case of fire PA system automatic start announcement to evac said area.

Visitor Management Systems (VMS)

For many companies and organizations, a manual paper-based VMS will suffice, providing visual identity of visitors. However, computerized systems linked to Access Control and Time & Attendance systems are the natural bedfellows for integrated security systems. These not only print ID passes, but can also incorporate biometric identification and the scanning of visitor/contractor documentation, licenses, certificates and insurance certificates.

Lift Control

By integrating lift control with the access control system, access to certain floors in a building may be

Restricted, particularly outside normal working hours or in multi-tenanted buildings. To monitor of lift you can fix CCTV Camera which is integrate with Access Control.

Car Park Management (CPM)

Where access to a car park is restricted, the ISMS can automatically monitor the number of spaces left for each tenant or department and regulate access accordingly. For example:

Visually through CCTV.

Audibly through an intercom system.

Automatic number plate recognition.

Access Control tokens.

Guard Tour System (GTS)

By using a guard tour package that integrates with the access door readers can be used to define and monitor a tour by a specific guard, providing a real time indication if the guard does not reach a set point in time (or even if he arrives too early) – equally integration with the CCTV system can provide visual verification of the guard’s location and wellbeing. Many Time & Attendance systems incorporate Guard tour functions as part of their software package.

Building Management Systems (BMS)

Building management systems are responsible for monitoring and controlling the environment of a building, for example lighting control, heating and ventilation (HVAC). In the current climate of energy saving, why leave lights on when an area is unoccupied? By integrating Access Control Systems with BMS systems, the lighting can be automatically controlled by recording when people access an area. The system can also be configured to control the heating by reducing the room temperature when no one is present rather than leaving it on all day and off at night.

Electronic Point of Sale (EPOS)

The logic of integrating security systems together is evident, however if information from systems such as EPOS can be interfaced then a powerful security solution for applications in the retail market and casinos can be deployed.

Data sent from an EPOS system can be overlaid on a live video display, allowing operators to view the camera feed and till transaction simultaneously. The transaction information and alarms enerated by the EPOS system can be bookmarked and recorded alongside the video. This facilitates visual identification of an incident in both real time and through post-event analysis. Powerful transaction analysis can be undertaken on the stored data, for example, finding out when a particular credit card was used by searching every till in a store or across all stores from the head office.

Conversely, recorded video can be searched using a thumbnail feature, which displays a video still image for every transaction, allowing the operator to quickly identify the relevant footage. Evidential quality video clips and associated transaction data can be exported for investigation or use in court.

Alarms generated by the EPOS system, such as ‘register drawer left open’, ‘refund’, or ‘large dollar amount’ can automatically trigger a number of events, including displaying the nearest camera to the specific till and pinpointing the alarm on an interactive map.
