Perimeter and interior represent which categories of sensors?

The distinction between perimeter and interior sensors falls under major categories of intrusion detection systems. Perimeter sensors are designed to detect unauthorized access at the boundaries of a protected area, such as fences or walls. They often include devices like motion detectors or beam sensors. Interior sensors, on the other hand, are deployed within a building to monitor movements and activities, targeting areas after the perimeter has been breached.

Classifying sensors into major categories helps in effectively organizing and implementing security measures based on the unique requirements of a facility. Understanding these categories allows security professionals to choose appropriate sensor types based on the layout and security needs of the premises. This classification ultimately aids in the efficient allocation of resources to safeguard environments against potential intrusions.
