What is a Perimeter Intrusion Detection System (PIDS)? A Perimeter Intrusion Detection System (PIDS) is a security solution specifically designed to detect unauthorized access or intrusion attempts along the physical boundaries of a facility, such as a building, industrial site, military installation, or other sensitive area.The primary purpose of a PIDS is to provide early warning and detection of intruders, enabling security personnel to respond quickly and effectively to potential threats. PIDS can be implemented using a variety of techniques and methods, including: Fence-mounted sensors: These sensors detect attempts to climb or cross fences. Examples include vibration sensors, tension wire systems, and fiber optic sensors. Buried cable sensors: Buried cable systems detect pressure or movement associated with a person or vehicle crossing a buried cable, which is typically installed at the perimeter of a protected area. Video Analytics: Video surveillance cameras equipped with intelligent video analytics software can detect suspicious activity or movement in the perimeter and trigger an alarm or notification. Hybrid systems: PIDS can also combine different detection technologies to increase overall effectiveness and minimize false alarms. Once a PIDS detects a potential intrusion, it can take a variety of actions, such as: Send an alarm or notification to security personnel or a central monitoring station. Activate alarms, lights or other deterrents to stop intruders. Trigger video recording or live monitoring from video surveillance cameras.
