Physical Access Controls:

There are several types of physical access control methods that can be applied to administer, monitor, and manage access to a facility. These physical access control mechanisms range from deterrents to detection mechanisms. If facilities that have different sections, divisions, or areas that are designated as public, private, or restricted should have specialized physical access controls, monitoring, and prevention mechanisms for each of the designated areas.

These methods can be used to separate, isolate, and control access to the areas of the facility and include fences, gates, turnstiles and mantraps; security guards and guard dogs; badges, keys and locks; motion detectors and alarms; as well as adequate lighting.

A fence can be used to cordon off different areas and can include a wide range of components, materials, and construction methods. It can come in various constructs: painted stripes on the ground, chain link fences, barbed wire or cement walls. Various types of fences are effective in keeping out different types of intruders: fences that are 3 to 4 feet high hinder casual trespassers; fences that are 6 to 7 feet high are difficult to climb; and fences that are 8 feet high with three strands of barbed wire deter aggressive intruders.

Gates can be used to control entry and exit points in a fence. The deterrent of a gate must be equivalent to the deterrent level of the fence to maintain effective security of the fence as a whole. Additionally, hinges and locking mechanisms of the gate should be fortified to diminish tampering, destruction, or removal. And as an extra layer of security, gates can be protected by security guards, guard dogs or CCTV.

A turnstile is a specialized gate that allows only one person at a time from gaining entry to a building or room, and often permits entry but not exit or vice versa.
