Locating fence-mounted intrusion detection sensor

FlexZone is a cable-based fence-mounted system that detects and locates any attempt to cut, climb or otherwise break through the fence. FlexZone adapts to a wide variety of fence types and is ideal for sites of all sizes.

Features and benefits

  • Detects and locates intrusions over a distance of up to 600 m (1968 ft) per processor
  • Pinpoints intrusions within 3 m (10 ft)
  • Accurately locates intrusions even when there are multiple simultaneous intrusions and in the presence of background environmental noise
  • Flexible software-based zoning (up to 60 distinct zones per processor)
  • Minimal infrastructure requirements – power and data run over sensor cables
  • Differentiates between point disturbances caused by real intrusions and spatially distributed disturbances such as wind and rain
  • Continues protection even in the event of a cable cut
  • Easy to install and maintain
  • Wireless Gate Sensor option

How it works

Using signals generated by the minute flexing of its loose tube coaxial sensor cable, FlexZone detects and locates movement of the fence. High-speed sampling ensures that the FlexZone processor captures a precise picture of the fence signal and enables advanced algorithms to discriminate between intrusion signals and environmental noise. This maximizes the probability of detection while virtually eliminating nuisance alarms caused by environmental effects such as wind or rain.

FlexZone® Wireless Gate Sensor

A simplified intrusion detection solution for sliding and swinging gates, the FlexZone Wireless Gate Sensor detects attempts to open, cut, climb or otherwise break through sliding and swinging gates and complements the coverage of the FlexZone fence-mounted sensor.

Features and benefits

  • Eliminates complex routing of cable from fence to moving gate panels
  • On-board auxiliary input for monitoring gate contact
  • Available in solar-powered and battery versions
  • Easy to install and maintain

How it works

The FlexZone Wireless Gate Sensor is a small, all-weather accelerometer-based sensor module which is attached directly to the gate fabric and sends alarms over an encrypted RF link to a nearby FlexZone processor.


Fiber optic cable intrusion detection sensor

Using fiber optic sensing cable, IntelliFIBER detects attempts to cut, climbing on or lifting the fence fabric by analyzing the signals generated by flexing the cable.

Features and benefits

  • Detects intrusions for up to 1 km (3,280 ft) per processor
  • Powerful Digital Signal Processing (DSP) (available in single or dual zone configuration) monitors independent zones
  • Available in 2-core cable version for sensing only, 4-core version for sensing and data communication and 4-core with integrated power for combined sensing, data communications and power distribution
  • Immune to EMI and RFI

How it works

IntelliFIBER’s unique signal processing incorporates a set of non-volatile programs called adaptive algorithms. This adjustable firmware allows features such as ambient compensation and common mode rejection to interpret the nature of the disturbance, virtually eliminating alarms caused by natural or environmental events. An optional weather sensor is available to provide each signal processor with independent verification of the current weather conditions affecting its performance. IntelliFIBER will adapt to these conditions without sacrificing detection sensitivity.
