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
