Gallagher offers intelligent fence controllers and a range of sensor technologies, including Z10 Tension Sensor, Z20 Disturbance Sensor and Gallagher Fence Integrity Monitor. These technologies complement electric fence perimeter security, to detect intrusions without the deterrent electrical pulse. It can be used in conjunction with the networked Gallagher electric fence system as an added layer of detection, or it can be mounted on a standalone system for low-security sites which want to monitor activity without the deterrent pulse.
