Z20 Disturbance Sensor

The Z20 Disturbance Sensor heightens perimeter security through the intelligent detection of vibration or movement of the fence structure. Alarms are generated when the disturbance meets predefined criteria.

From multi-technology, layered, security solutions which are fully integrated with Gallagher Command Centre, to simple perimeter systems requiring an uncomplicated form of detection, the Z20 Disturbance Sensor provides superior security detection.
