Senstar FiberPatrol-PR fibre optic fence-mounted sensor now offers extended detection range

Senstar, a manufacturer of perimeter intrusion detection systems (PIDS), announced that FiberPatrol-PR, its fibre optic fence-mounted sensor for perimeter applications, now provides up to 50 km (31 mi) of protection per processor, more than doubling the system’s previous detection range capability of 24 km (14.9 mi). The intrusion locating accuracy of the system has also improved to within 4 m (13 ft.) from the previous 8 m (26 ft.).

Perimeter protection

“This is the second time in just over a year we have implemented extended range capabilities for FiberPatrol-PR,” said Product Manager Stewart Dewar. “By enhancing the system, we are able to provide customers greater protection and more accurate locating with less infrastructure. This results in more economical deployments for long perimeter sites, including borders.”

FiberPatrol-PR uses proven fibre optic technology to detect and locate intrusions. The system has a reduced nuisance alarm rate because it can differentiate between disturbances caused by real intrusions and environmental disturbances such as wind and rain.

Accurately locating intrusions

FiberPatrol-PR can detect and accurately locate intrusions even when there are multiple simultaneous intrusions or in the presence of spatially-distributed environmental noise that would mask the detection capability of other long-range fibre optic sensors. As well, the system’s resilient design allows detection to continue right up to the point of a cut in the sensor cable. The system can also be deployed in a cut-immune configuration.

FiberPatrol-PR requires no powered or conductive items in the field, making the sensor completely immune to EMI and lightning and intrinsically safe in the presence of explosive atmospheres.
