System description
FiberPatrol Overview
The FiberPatrol FP1150 perimeter intrusion detection system detects and locates intruders using
fiber optic technology. For fence-mounted applications, FiberPatrol senses and locates minute
vibrations in the fence caused by climbing, cutting, lifting, or otherwise disturbing the fence fabric.
A fiber optic sensor cable is attached to the perimeter fence. The sensor unit (SU) transmits laser
light into two single-mode fibers in the sensor cable. The SU picks up the back-scatter reflections
caused by fence motion or vibrations in the fence fabric and processes the data to determine the
magnitude and location of each disturbance. The sensor unit triggers an alarm when a disturbance
meets the criteria for a valid intrusion. One FP1150 SU can monitor up to 80 km of perimeter
fence.
The FiberPatrol FP1150 can provide covert long-range protection against third party interference
(TPI) for buried pipelines or data conduit. In addition, the FP1150 can be configured to provide
intrusion detection of people, vehicles and tunneling activity. The FiberPatrol sensor detects and
locates minute vibrations in the ground. Depending on the application, the burial media and the
detection settings, FiberPatrol can detect digging, boring, or otherwise disturbing the ground near
a pipeline’s right of way, as well as nearby vehicles, human intruders and tunneling activity. One
FP1150 SU can monitor up to 100 km of buried pipeline or data conduit for TPI. To detect people
or tunneling activity, one FP1150 SU can monitor up to 80 km.
For fence-mounted applications the sensor cable is a communication-grade single-mode fiber
optic cable intended for outdoor installation. The cable includes two dedicated sensing fibers.
Depending on the particular fiber optic cable used, at least 10 dark fibers are available for other
perimeter applications (e.g., CCTV, data communication, etc.). The sensor cable is easily attached
to the fence with cable ties. However, all fiber connections require fusion splicing to telecom
industry standards. The sensor unit fiber optic connections use FC/APC type connectors.
For buried applications, and for fence-mounted applications which require additional protection
against accidental damage and vandalism, the sensor cable is an armored, communication-grade
single-mode fiber optic cable intended for direct burial in soil. The cable includes a dedicated
sensing fiber, and a number of dark fibers which are available for other applications. FiberPatrol
sensor cable requires professional installation using industry standard practices. High quality
fusion splices are required, and outdoor splices and fiber drop points are protected inside
weatherproof enclosures which are installed in buried vaults.
One FP1150 SU can monitor different types of sensor cable installations; for example, fence
mounted and buried cable. In this case, a 30 m (100 ft.) coil of sensor cable is recommended to
serve as a buffer at the transition between the different installation types.
