Detector fences are a patented very high-security solution. The first function of these products is to physically prevent an intrusion. The fence panels mounted on the poles consist of two plates (with electric current running through each of them), isolated from each other. Any cutting or tearing-down attempts creates a short-circuit and triggers an alarm.
For optimum protection, it is possible to equip the top of the fence with an overhang system (with automatic reset) in order to detect climbing attempts.
