Alarm principle:
Clothing store burglar alarm is also called clothing burglar alarm system. At present, there are mainly two kinds of audio magnetic burglar alarm and radio frequency burglar alarm used in the market, and the audio magnetic system is actually the one that is used more at present.
It is based on the physical principle that the tuning fork only causes * * * vibration at the same oscillation frequency to prevent theft. When the anti-theft buckle fixed on clothes enters the detection area of the system, it will vibrate with the detection signal sent by the anti-theft device, and the * * * vibration signal will be amplified by the system and converted into an electrical signal to be connected to the audible and visual alarm, thus triggering an alarm.
In order to inform the staff in the store in time and achieve the purpose of anti-theft and stop loss, the acousto-magnetic anti-theft device has the characteristics of high anti-theft detection rate, less false alarm, good anti-interference and wide export protection. But its price is higher.
