Outdoor perimeter security typically requires the owner to take a holistic and complete assessment of the outdoor space. This enables the property owner to understand the challenges of the outdoor areas and deal with them accordingly. For instance, large trees that could conceal intruders will require pruning. Similarly, dense undergrowth in the lawn will require trimming too. Such measures could be useful for enhancing the perimeter security of the property. Ideally, the measures you use for securing the outdoor perimeter of the property should follow the 5D perimeter approach, namely:
Deterrence: The deter perimeter will be furthest from the asset location. As such, it will typically feature fences and lights. This perimeter will aim to deter the intruder from even attempting to breach the security system. It will utilise surveillance technology (including the drone thermal camera) for communicating a deterrent message to unauthorised individuals.
Detection: The objective of the detect perimeter is to monitor large areas for detecting the presence of intruders. The tools used for accomplishing this include megapixel cameras, among other surveillance camera technology.
Denial: The deny perimeter seeks to enable authorised personnel to enter the area, whilst keeping intruders out. This typically requires access control technology or manned security at the point of entry.
Delay: This perimeter seeks to slow down the intrusion sufficiently. This will serve to force the intruder to abort the intrusion. At the same time, it will give sufficient time for the security team to respond to the intrusion. The devices used for accomplishing this include interior locking doors and other physical barriers.
Defend: This perimeter comprises a security personnel response to the intrusion. The aim of this perimeter focuses on apprehending the intruder.
