This article presents four case studies emphasizing trends in requirements for perimeter intrusion detection systems.
Abstract
The traditional application for a perimeter intrusion detection system (PIDS) was securing an exterior recreational facility. However, today's PIDS are used in drug control, professional intrusion, early warning for administration areas, and even boot camp perimeter checks. The most popular PIDS technologies are beams (infrared and microwave), fence acoustic sensors, ground pressure sensors, and field disturbance sensors, the last being the focus of this article. The article presents four case studies drawn from examples in the United States, Canada, and Australia. The first study examines a new roof detection system. The second describes a wall-top application, combined with razor wire, to detect attempts at bridging the wall. In the third study, the PIDS is buried in the soil on the inner side of the recreational area fence and is used as an early detector to alert the central security office of an inmate's presence close to the fence area. The fourth study describes securing access to covered walkways. References
