Your perimeter security features deliver three extremely important functions in your front line defence of your physical security plan; deter, detect and delay.
Deterrence: Your perimeter security should be designed to deter most would be thieves from picking your facility as their target of choice. Security professionals must remember that no facility is completely void of all would be thieves. The installation of signs, lighting, electronic devices and the use of security personnel all have an influence on those thinking about your facility as their next target. If your plan is implemented properly, those would be thieves who know very little of the prize that awaits inside your facility will move on.
Detection: The dedicated and desperate thief most likely will not be deterred. Detection of the thief is paramount in protecting your assets within. Where possible your perimeter detection devices should be placed as far away from the asset as possible. Detecting the thief’s intentions at the earliest possible point is crucial. The earlier the detection the greater amount of time given to security personnel and law enforcement responders to react.
Delay: Your perimeter should provide enough of a delay to the would be thieves even though detection has already occurred. Here is an example; metal bars on windows. If you don’t supplement these with a detection device the would be thieves can sit there all day working on defeating the metal bars. Your delay elements and detection elements should be configured together to be effective.
Your environment can greatly affect the design and use of your perimeter protection. Security professionals must consider the weather, wildlife, landscaping, and even your soil. Many devices can be affected by these things and more.
Security professionals can use a multitude of methods to install devices to reduce false alarms. The installation of dual technology, complimentary devices or simply combining different types of devices can help reduce or even eliminate false alarms. If these devices are installed incorrectly without the consideration of the environment not only may it lead to continuous false alarms but create a weakness in your perimeter.
Even though technology is getting better by the day, proper planning, testing and implementation of devices should be done with the consultation of a security professional.
Remember, you can’t stop crime but you can re-direct it.
