Perimeter security types – Permanent and Temporary
Perimeter security has been around as long as people started owning property. Perimeter protection systems outline boundaries around the property and separate different zones in the facility from each other. Traditional perimeter protection systems were walls, fences, hedges, and other permanent barricades that defend your property against intruders and trespassers.
But today the perimeter is high-tech and reach skies with radars and sensors detecting even the smallest intrusion, however, this comes into play only in the defence sector. Most commercial facilities adopt access control systems and automatic gates to get active barrier security for their facility.
Modern perimeter security
Today, with the invention of the burglar or intruder alarm, the world has seen a dramatic shift away from perimeter security to internal building security. Domestic and business owners have relied on electronics to secure their buildings internally, which, over time reduced property owners and dwellers’ dependency on physical perimeter security.
However, buildings like ministries, military stations, embassies and other critical facilities continue to use tough barricades to stop intrusions using, bollard, road blockers and tyre killers etc. And these solutions too have gone through several evolutions and are today operated automatically with the use of sensors and automatic controls.
Passive barriers and active barriers:
Passive barriers are fixed barriers that act as fencing to block access to a vehicle or a person. Passive barriers include all of the following – fences, walls, moats, bollards, heavy trees, or even just big rocks.
Majority of them keep out all types of traffic. Meanwhile, active barriers are usually mechanised or automated. They act as gate/entry system that can control the flow of traffic manually or automatically.
Passive Barrier Types
As mentioned, passive barriers have no moving parts; their effectiveness depends on the deterrence they offer to stop incoming vehicles.
Walls, fences, wedges: Concrete walls are one of the most common perimeter protection system used by facilities to demarcate their areas. Terrains and landscapes can be used as an effective vehicle barrier as well. Another common perimeter barrier is bollards – they are short, vertical posts used to protect potentially vulnerable structures or objects from damage by moving vehicles.
Fixed Bollards: Fixed bollards are usually made of concrete or reinforced steel, their deterrence is rated in order of typical impact ratings (Eg: K-rating & M-rating). Fixed bollards are the most common type of bollards, they are permanent fixtures and provide strength and deterrence. They are built in steel and filled with concrete. Even though they provide better deterrence, they are not ideal for places like parking lots and garages where there might be a need for free passage at times.
Active barriers types
Active barriers usually work as access control points, are primarily found in a facility’s access control points. The main form of active barriers that most people associate with is the arm gates, automatic gates etc.
Access control systems: Access control systems serve to restrict entry only to authorized personnel. By a pin, fingerprint or biometric pattern identification system, access to the perimeter of the plant is allowed, preventing the access of intruders. It also serves to delimit the spaces of the factory that can be accessed by staff and to dispense with keys.
Automatic Bollard & Barriers: Retractable Bollards are another common type of active barriers. They are frequently used where there is mixed vehicular and pedestrian traffic. Automatically rising bollards rise and retract in and out of the ground-based on their control device and they are operated by either a hydraulic or electronic motor. They’re an efficient, versatile way to control traffic without any human interference. Made with steel, or other composite material, they provide different degrees of deterrence.
Do you need perimeter protection?
Vehicles: How do you decide, if you choose active or passive barriers for your facility. There are a few points you need to keep in mind. The first, most important point to take into consideration is if the site will have both pedestrian and vehicular traffic. The other important factor is knowing traffic patterns, types of vehicles, peak times, flow rates, access requirements and authorization level. Barriers can be either active like automatic boom gates or passive like a fixed bollard.
Pedestrians: If perimeter protection is required to block people on foot from entering the facility then, gates or turnstiles are the best options. One needs to understand foot flow patterns and mixed traffic possibilities. The vehicle barriers also have to be planned according to how they will allow pedestrian.
The stipulated clear gap between vehicle barriers along a perimeter within the PAS 68: 2013 standard is 1,200 mm.
Security provided by barriers has many different degrees of safety options. Safety access, the value of the secured property, and the risk of intrusion associated are all essential questions to look at while you decide on while you are planning for perimeter protection solutions.
