Perimeter Protection
Microphonic Cable Intrusion Detection Sensor
|
|
NVS will install and intergrate the new Intelli-FLEX™ system to the existing fencing structure.
Intelli-FLEX™ is a unique microphonic intrusion detection system for outdoor, fence-mounted perimeter
security applications. By analyzing signals generated by the minute flexing of a proprietary triboelectric
coaxial sensor cable, specific characteristic intrusion signatures are analysed by a powerful digital Signal
Processor. Raising alert to the control room and activating a PTZ camera.
Installation is quick and simple.
Inexpensive UV-resistant tie
wraps secure the sensor cable
to the fence at 30 cm (1.0 ft.)
intervals. The Intelli-FLEX Signal
Processor can monitor two
independent zones, each with a
maximum of 305 m (1000 ft.)
of sensor cable.

• Low cost
• Quick and Easy to Install
• Digital Signal Processing
• High Probability of Detection
• Independent Detection of
Fence Cutting and Climbing

A programmable microprocessor enables the user to set the operating parameters for each zone
using a simple plug-in Configuration Module. Separate parameters are set for cut and climb detection,
resulting in independent alarm processing to optimize detection and minimize false alarms. Since the
coaxial sensor cable is microphonic, an optional plug-in audio module enables the user to “listen-in” to
the fence activity. This feature provides an additional low-cost tool for assessing the nature of an
intrusion attempt. More systems are available on request.
