What can be monitored?



The intrusion detection system PeriGuard is a security system based on fiber optic sensing technology and is designed for short and medium perimeter applications with up to eight detection zones. All zones operate autonomously; a sensing cable failure or an intruder on any zone will not affect the performance on any other zone.

The PeriGuard GS intrusion detection system consists of two main components: the sensing cable and the reading unit. This setup can be used as a buried, fence, wall or roof installation.

Fiber optic sensing cables do not contain any metal parts and as a result they can not be detected when burried or embedded in the wall.

The whole setup is passive and immune to EMI/RFI.
