Perimeter intrusion detection

A perimeter intrusion detection system (PIDS) is a device or sensor that detects the presence of an intruder attempting to breach the physical perimeter of a property, building, or other secured area. A PIDS is typically deployed as part of an overall security system and are often found in high-security environments such as correctional facilities, airports, military bases, and nuclear plants.

Types of PIDS

A wide range of intrusion detection technologies exist in the current marketplace. The U.S. Army, as part of their reference material for personnel responsible for planning and executing security programs, divides PIDS technologies into the following categories:

• Passive IR
• Active IR
• Microwave detectors
• Near-IR beam break
• Fence-mounted
• Taut wire
• Ground motion
• Ported coaxial cable
• Seismic
• Acoustic
• Magnetic
• Break wire
• Electrostatic field
