FenSense is an innovative, integrated perimeter security system where the fence itself acts as part of the sensing mechanism. Utilizing the FICID (Fence Impedance Characterization for Intrusion Detection) algorithm (patent pending), the system continuously monitors changes in the signal passing through the fence to detect any attempted cuts or climbing intrusions. This unique fence security sensor integrates the fence structure—such as mesh and razor coils—into the sensing system, making it completely discreet without the need for visible additional alarm sensors.
