Is the supermarket anti-theft eas alarm system in the supermarket really useful? [Bohang China]
In daily life, you can often see the presence of anti-theft devices at the door of supermarkets and clothing stores, and more and more businesses choose to install anti-theft systems in their own stores, but does it really work after installation? This problem has also plagued many people. Today, Bohang China came to share with you the correct answer of "Does the supermarket anti-theft eas alarm system really work?"
Judging whether the supermarket anti-theft eas alarm system is really useful, first of all, it is necessary to analyze its working principle. The two kinds of supermarket anti-theft devices commonly used in the market are the EAS AM anti-theft system and the radio frequency anti-theft system. The acoustic magnetic system is applied with the tuning fork in the same situation with the same oscillation frequency. The physical principle of resonance, so as to realize the alarm work, the characteristics of the EAS AM system are high detection rate, almost zero false alarm, good anti-interference, and wide exit width of protection.
There are two kinds of anti-theft tags for soft and hard. The product can be protected and can be degaussed even if the system is working properly next to the POS cash register. The radio frequency anti-theft system uses radio waves as the signal for transmitting and receiving. There is a stable electric field in the middle of the two antennas. The anti-theft tag is a resonant circuit. When the electric field between the antennas passes, the resonance point resonates and the electric field is instantaneous. The change occurs to trigger the alarm. The RF system has low cost and is easy to install, but the false alarm rate is high and the anti-interference performance is poor.
Whether it is a EAS AM anti-theft system or a radio frequency anti-theft system, as long as it is effective in a suitable installation environment, the size of the action is in cooperation with the loss prevention personnel of the supermarket, the layout of the anti-theft tag is placed, and the layout of the product is related. The real role of the supermarket anti-theft eas alarm system is not to catch thieves, but to scare and shock those who have theft, do not dare to steal in the supermarket, indirect coordination with security personnel to carry out theft is his real meaning of loss prevention . So the supermarket anti-theft eas alarm system is really useful!
