What type of sensor is an interior following zone?

An interior following zone specifically utilizes motion detectors. This type of sensor is designed to detect movement within a specific area inside a facility. The purpose of an interior following zone is to monitor spaces where motion might indicate unauthorized entry or unusual activity, thus allowing for a rapid response to potential security breaches.

Motion detectors function by sensing changes in the environment, usually through methods such as passive infrared sensing, microwave detection, or dual technology combining both. This makes them particularly effective in an interior environment where continuous surveillance is crucial, as they can differentiate between authorized movements (like residents or employees) and unauthorized intruders.

While glass break sensors are useful for detecting the shattering of glass and can alert for perimeter breaches, they do not monitor entire interior spaces. Magnetic sensors are typically employed on doors and windows to indicate open or closed states. Heat detectors focus on changes in thermal energy and are ideal for fire detection rather than security monitoring. Therefore, motion detectors best fit the description of an interior following zone in a security context.
