Security perimeter

A security perimeter is the technology and physical barriers put in place to prevent unauthorized people from entering a building.

What is a security perimeter?

A security perimeter is all of the physical and technological barriers put in place to prevent unauthorized entry into a facility. Physical barriers include doors, fences, walls, and locks. Technological barriers include video alarms, access control systems, window alarms, etc. Security perimeters can be time dependent, for example excluding all people outside of normal operating hours or only allowing deliveries in the morning.

Why is a security perimeter important?

Maintaining a strong security perimeter is a key part of a loss prevention system. A company needs to understand who should be allowed to go where and when within their facility to prevent merchandise from being stolen or damaged. A security perimeter can also reduce liability by preventing injuries. Many worksites have dangerous equipment in use that requires specialized training. An unauthorized person entering such sites represents a liability to the company.

It is also important to understand how the different components of a security perimeter support each other. Video alarms can support physical locks on doors and windows by alerting owners and emergency personnel to unusual activity outside of entrances. It might take a burglar several minutes to open a door. While the access control system will alert authorities when the door is finally opened, video alarms can let you know that a person is already trying to gain entry into the building.
