How does the supermarket anti-theft eas security gate work? [Bohang]


The supermarket anti-theft eas security gate RF system radio system uses radio waves as the signal for transmitting and receiving. The transmitted signal is a radio signal, which is the same signal as a mobile phone or a broadcast, but with different frequencies. Its advantage is that the system cost is very low and the installation is convenient. However, because the anti-theft tag is a toroidal coil type, the system is susceptible to interference from some items, such as electronic products such as cash registers, metal objects, etc., causing false positives or failures of the system.

Supermarket anti-theft eas security gate AM system tuning fork only causes resonance when the oscillation frequency is the same. Acoustic magnetic system is the application of this physical principle, to achieve almost zero false positive operation, when the acoustic magnetic system tag fixed on the commodity enters the detection area of the system, it will resonate, but only received four times in the receiver. The alarm is generated after the resonance signal (once every 1/50th of a second). The characteristics of the acousto-magnetic system are high anti-theft detection rate, almost zero false alarm, good anti-interference, and the protection export width can reach 3.5 m. There are two kinds of anti-theft tags, which can protect most types of goods in the mall. And can degaussing repeatedly, even if the system is still working properly next to the POS cash register.

The supermarket anti-theft eas security gate electromagnetic wave system electromagnetic wave system uses electromagnetic waves as the detection signal. The electromagnetic wave system has the smallest label, the label price is also cheap, and the degaussing can be repeated, but it is susceptible to false alarms due to the influence of magnetic or metallic substances. The width of the protected exit is generally around 0.9 meters. The system does not affect magnetic items. The new generation of channel-type electromagnetic wave system is a software-controlled electronic anti-theft system that uses digital processing technology and degaussing system, cashier monitoring and closed-circuit television monitoring system. The use of a fast degaussing plate enables repeated degaussing and high system cost.
