The Smart Fence Vibration Sensor

Main objective

To detect immediate intrusion attempts by climbing, cutting or lifting a perimeter fence, or by the cutting of the sensor line, or power / communication cabling. 


Applied Sensor Technology

Vibration sensors deployed along most types of physical barrier’s, which can include chain-link, welded mesh fences / concertina coils, gates & walls.  Up to 1,500 metres of sensor lines can be controlled by a single system controller. 

The VIPER-SENS is the most efficient intrusion detection system in Kenya & East Africa, it is able to convert a wide variety of physical barriers, Chain-link, Welded mesh fences, concertina coils and walls to an indicative Smart Fence which is then capable of real time detection of attempts to overpass, damage, cutting or short cutting the property perimeter. 

The VIPER-SENS system utilises proprietary vibration sensors for default ±10m detection resolution, providing 20 metre alarm zones across the entire perimeter. A single sensor covers up to 10 feet fence height. The VIPER-SENS uses a single control unit for up to 1.5 kilometres sensor lines, with optional layout of up to 10 kilometres on a single power and communication source which makes it the ideal perimeter detection system for sites which need a high quality field proven system.

The VIPER-SENS Smart Fence Vibration system is now available in Kenya & East Africa.
