FiberPatrol FP1150

Fiber Optic Intrusion Detection System for Fence, Wall, and Buried Applications
Thumbnail Video Image

FiberPatrol FP1150 is a perimeter intrusion detection system that can be fence-mounted, buried, or deployed in a wall-top configuration. It can also be used to protect data conduits and buried pipelines. Advanced adaptive signal processing along with certified SMS/VMS integration options ensure the highest level of security and performance.

Detection Capabilities

  • Detects and locates perimeter intrusions over distances of up to 80 km (49.7 mi) per processor
  • Pinpoints intrusions with a +/-4 m (13 ft) accuracy
  • Flexible, software-based zoning
  • Accurately detects and locates multiple simultaneous intrusions
  • Reports alarms by zone number, cable distance and/or GPS coordinates.

Fiber Optic Benefits

  • No powered or conductive items required in the field
  • Immune to EMI and lightning, intrinsically safe in explosive atmospheres
  • Long sensor cable service life (25+ years)
  • Unused fibers can be reused for other applications
  • Possible to use sensor cable with fire ratings such as LSZH, fire retardant, and fire resistant

Experiential Intelligence

FiberPatrol FP1150 builds upon Senstar’s 40 years of perimeter intrusion detection experience to offer a system that detects and reports both common and sophisticated intrusion attempts almost instantly. Unlike generic AI systems that require extensive training and may fail when presented with unseen intrusion data, FiberPatrol is designed with intelligence built-in, works out of the box, and offers the highest levels of performance and system confidence.

How It Works

The FiberPatrol FP1150 works by transmitting pulses of laser light into a single-mode optical fiber and accurately measuring the minute light reflections that occur along its length. A disturbance of the fiber caused by fence vibrations changes the amount of light returned from that point. FiberPatrol’s reflectometry-based technology does not require the light to traverse the full length of cable. If a cable is cut, FiberPatrol retains the ability to detect and locate intrusions up to the point of the cut, thus enabling the system to support cut-immune configurations.


Cut Immunity

When the sensor cable is cut, either accidentally or in an attempt to defeat the sensor, FiberPatrol FP1150 immediately reports the incident, including its exact location. Moreover, the sensor retains the ability to detect and localize intrusions up to the point of the cut. When installed in the cut-immune configuration, the sensor continues to provide detection on the full perimeter even after a cable cut.

FiberPatrol FP1150 Features

Protect Sites with Confidence

With supported distances of up to 80 km (49.7 mi), FiberPatrol FP1150 is ideal for protecting a variety of sites, including airports, campuses, correctional institutions and petrochemical facilities. Complementary multi-layered detection algorithms minimize nuisance alarms generated by environmental effects like wind and rain:

  • Precise ranging provides for “environmental disaggregation”, which prevents randomly distributed disturbances within a zone from generating an alarm
  • Environmentally Derived Adaptive Processing Technology (EDAPT) adapts the detection process to compensate for the presence of sustained and extensive background noise caused by environmental effects, reducing false alarms and improving security

Enhance Existing Fence

FiberPatrol FP1150 works with chain-link, welded mesh and expanded metal mesh fences. A single pass of sensor cable provides effective protection for fences up to 4.3 m (14 ft) in height. The sensor may also be used on palisade-style fences depending on the specific characteristics of the fence.

Gate Protection

FiberPatrol FP1150 sensor cable can be installed on swinging gates to provide detection, and the gate area itself can be configured as an independent detection zone. Sliding gates are typically protected with Senstar’s Wireless Gate Sensor or UltraWave microwave sensor.

Buried Perimeter Detection Applications

When an intruder moves across the ground above a buried fiber optic sensor cable, whether walking, running, or crawling, characteristic vibrations are created. The system distinguishes these from background vibrations, and FiberPatrol FP1150 declares an alarm when the detection criteria are met.

High Availability

FiberPatrol’s FP1150’s redundancy configuration with automatic failover is transparent to the alarm system and end users. Each sensor unit also includes redundant hot swappable power supplies and SSDs.

Multi-Purpose Sensor Cables

FiberPatrol FP1150 uses single-mode fiber optic sensor within telecommunications-grade cable. In addition to having a nominal service life of 25+ years, unused fibers within the cable can be used for other purposes, including networking and providing communications to other sensors and security devices installed along the perimeter.

Networking and Integration

The integrated 4U sensor unit includes all necessary detection and gateway software – no separate integration server required. With built-in Ethernet and support for Senstar’s UltraLink family of I/O cards, FiberPatrol FP1150 can work with virtually any security system. Local and remote system management iis performed using a familiar Windows®-based GUI. For integration with third-party video, security, and physical security and information management (PSIM) applications, an SDK is freely available.

Wall-Top Applications

For walled perimeters, FiberPatrol FP1150’s sensor cable is mounted at the top corners of the wall. Any impact to the sensor cable by an intruder’s hands, feet, or climbing aid will be detected by the system. For highest security the sensor cable can be installed on both the inner and outer sides of the wall.

Common Platform

FiberPatrol FP1150 includes a built-in alarm display application and uses the same integration software as other Senstar products, reducing training requirements while increasing operational efficiencies. Running the Windows® operating system, the system is easy to configure and manage. Alarms, control, and status information can be managed by the Network Manager software, which provides a common unified interface for the Senstar Symphony Common Operating Platform as well as other industry-leading third-party systems.

Benefits of a fiber optic sensor

Fiber optic sensors are ideal for sites that are sensitive to electromagnetic energy. These sensors are immune to EMI and lightning, intrinsically safe in explosive atmospheres, and require no powered or conductive components in the field. Other benefits include: unused fibers can be reused for other applications, 25+ year cable service life, and cut-immune configurations (when supported by the sensor).
