(1) The principle of high safety, high temperature resistance, low temperature resistance, and anti-interference. The principle of using the external vibration to generate the induced electromotive force generated by the cutting of magnetic lines of force by the movable conductor in the vibration cable, to realize the detection of intrusion in the defense zone.
(2) The longest distance of each defense zone can reach 400 meters.
(3) It is suitable for various complicated terrains, and can detect the irregular perimeter defense zone.
(4) It can be directly laid on various iron nets, iron art, plastic steel, brick walls and irregular fences.
(5) Long service life and low maintenance.
