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. © 2007 IEEE.

Security system analytical performance analysis is generally based on the probability of system effectiveness. The probability of effectiveness is a function of the probabilities of interruption and neutralization. Interruption occurs if the response forces are notified in sufficient time to engage the adversary. Neutralization occurs if the adversary attack is defeated after the security forces have actively engaged the adversary. Both depend upon communications of data. This paper explores details of embedded communications functions that are often assumed to be inconsequential. It is the intent of the authors to bring focus to an issue in security system modeling that, if not well understood, has the potential to be a deciding factor in the overall system failure or effectiveness.
