External intrusion detection systems for critical facilities

A description is presented of the application of Sparton sensors and systems to perimeter intrusion detection around high-security military and civilian facilities. The system is primarily concerned with protection of approach areas, and assumes that other equipment or systems will be used for detection and identification within the physical boundaries of the secured facility. While Sparton equipment is designed for detection in open areas some sensors are quite suitable for internal detection as well. The system described is based on protection of a hypothetical power plant, and is chosen to illustrate how specific sensors can be used. Other facilities, such as military bases, precious or dangerous material storage areas, or national security buildings could utilize similar sensors. Using radio links, these systems can protect much larger areas such as airfields or national borders
