System description
Principles of operation
The FiberPatrol FP1150 fence-mounted perimeter intrusion detection system detects and locates
intruders using fiber optic technology. 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.
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.
The FiberPatrol system includes Windows-based configuration and alarm display software, which
is used to setup and calibrate the system. The configuration software can also serve as an
operator interface to the system for alarm monitoring. The configuration software enables sensor
calibration, detection parameter adjustments, system configuration settings and alarm processing.
FiberPatrol can operate as a standalone sensor, which communicates alarm conditions via
optional relay output modules. A PC-based security management system, such as the Network
Manager’s Alarm Integration Module, or StarNet 2, can serve as the primary operator interface for
a FiberPatrol system. FiberPatrol can also report alarms to 3rd party security management
systems (SMS) via the Network Manager Service. The security management system monitors the
FiberPatrol sensor, and can report alarms to an operator on a graphic site-map.
