An electronic fence is a perimeter intrusion alarm system consisting of a controller and a detection fence. The controller generates and receives high-voltage pulse signals, triggers an alarm when the detection fence is touched, short-circuited, or broken, and sends intrusion signals to the security alarm center. The detection fence forms a physical perimeter consisting of posts, metal wires, and other components. Multi-level networking can be configured through a control keypad or software. As an active intrusion deterrent, the electronic fence repels intruders and delays unauthorized entry without endangering human life. It also sends intrusion signals to security monitoring equipment, enabling personnel to promptly assess the affected area and respond quickly.
