What is perimeter intrusion detection?

Perimeter intrusion detection refers to a technology specifically designed to monitor and detect unauthorized entries along the edges or boundaries of a property. This is crucial for a security system as it helps ensure the integrity of the premises by providing an initial layer of defense against potential intruders. The system can employ various technologies, such as sensors, motion detectors, and fencing with integrated security measures, to identify any attempts to breach the perimeter before they can escalate into more serious security threats.

This proactive approach not only helps in preventing unauthorized access but also enables security personnel to respond quickly to potential breaches, ultimately enhancing the safety of the property and its occupants. The ability to detect intrusions at the perimeter is vital for effective risk management and security planning.

The other options provided do not align with the concept of perimeter intrusion detection, as they focus more on internal monitoring, health assessments of security staff, or surveillance within buildings, rather than on the critical function of safeguarding the outer boundaries of a property.
