The tension fence detection system is a physical defense fence thatcombines technical and physical defense. The system adopts a fully sealedUnited-Y15 sensor, which is based on the principle of tension detection anda special electrical signal processing method. It can effectively detect theintrusion behavior of illegally crossing the tension fence and sense theelectromechanical device assembly that transmits (alarms) tension, compression, and cutting obstacle information. It is currently the safest,most reliable, environmentally friendly, and digitally intelligent perimeterintrusion prevention alarm system in the world.The system supportsalarms for all detection units
