Virtual perimeter security (VPS) in a physical protection system

There is a need to provide response force personnel with advanced warning of intruder activity in rough terrain outside the traditional facility perimeter. Often the land surrounding a high consequence facility is remote and difficult to sensor with conventional long-range detection systems. In order to combat this difficult problem, Sandia has investigated, developed, and fielded a wireless sensor network that demonstrated the value of providing advanced information of adversary activities. The project used wireless technologies to detect and assess intruders in remote "un-engineered" terrain around a fixed facility. In the time since the wireless intrusion detection system was fielded, minimal time has been spent on maintenance and no batteries required replacement. Sandia's wireless sensor network provides advanced warning of intruder activities and its installation will improve the security posture of a facility
