FlexPS ™ Microphonic Cable Intrusion Detection Sensor

Company: Fiber Guard (Pty) Ltd

Type: Sensors, Detection Equipment

FlexPS ™ is a mounted sensor providing assured detection of any attempt to cut, climb or otherwise break through the fence. Advanced digital signal processing allows it to adapt to a wide variety of fence types. FlexPS ™ builds upon Senstar’s wealth of experience with it’s Intelli-FLEX ™ and FPS fence sensors to deliver a sensor that is simple to install, provides networking capability for remote alarm reporting and configuration, and works reliably in the most extreme environments.


FlexPS ™ gives advanced warning of unwanted intrusions at the perimeter and is easily installed on most fences by attaching it’s lightweight sensor cable to the fence fabric with cable ties. The FlexPS ™ processor is outdoor rated and easily post mounted or fixed to any convenient supporting surface. Alarms can be reported locally at the processor via relays or communicated to a central location using optional networking capability. For extreme protection, the Armour-Flex ™ sensor cable adds a flexible steel conduit outer jacket to the standard cable.

How it works

Using signals generated by the minute flexing of its proprietary Microphonic Electret Xducer (MEX) cable, FlexPS ™ detects intruders climbing, cutting or lifting the fence. Each FlexPS ™ processor provides connection for two sensor cables that can be up to 300 m (984 ft.) long and act independently to provide two distinct detection zones. Alarm outputs and system status are communicated by relay outputs or over a data communications network to a remote security management system
