Digital Vibration Detector

Type: AS-971A


Related: Alarm Dectector


AS-971 digital vibration detector adopts the international advanced photoelectric vibration sensing principle, combining the vibration sensor and vibration analyzer, with the CPU processing technology, induces the degree of vibration damage through the vibration of the sound source wavelength and frequency.
It is applicable to various models ATM automatic teller machines, vaults and different sizes of safe and other equipment to detect, effectively prevent hit, drill, pry and other destructive behavior on the equipment. It has been used for the major banks ATM automatic teller machines and other equipment.
