Which feature is designed to detect unauthorized entry at the exterior boundary?

• A. Perimeter Intrusion Detection Systems
• B. Panic buttons
• C. Access control
• D. Video Security

Answer: (A)

Perimeter Intrusion Detection Systems are designed to detect unauthorized entry at the exterior boundary. They place sensors along fences, walls, or other outer edges of a property to sense disturbances from climbing, cutting, or breaching the perimeter. When a breach is detected, the system immediately raises an alert for security to respond, often integrated with monitoring and other controls to speed up the reaction. This focused role on the outside boundary is why it’s the best choice for detecting intrusions before someone gets inside. Panic buttons are for triggering an alarm in an emergency from within or near a location. Access control manages who can enter at specific points, not the outer boundary itself. Video security provides visual monitoring and can help identify intruders after the fact, but it isn’t primarily built to detect boundary breaches in real time.
