How to buy a supermarket anti-theft device? [Bohang China]


How to buy a supermarket anti-theft device? There are many types of security doors on the market, but there are only two types of anti-theft devices commonly used in supermarkets. One is the RF security door, and the other is the acoustic magnetic security door. The large feature of the AM eas anti-theft device is almost zero false alarm. When the anti-theft tag fixed on the product enters the detection area of the system, it will resonate, which will trigger the alarm of the supermarket anti-theft device.

Because of the principle of the acoustic magnetic anti-theft device, the acoustic magnetic anti-theft system can be highly resistant to interference, almost zero false positives, and the anti-theft detection rate is high. The width of the protected outlet is obviously longer than that of the radio frequency, and the highest can reach 2.7 meters. Both anti-theft tags and soft labels protect most of the contents of the supermarket and can be degaussed even in our cash register system. However, the disadvantage is that the production process and installation process of the sound magnetic supermarket anti-theft device is more complicated than the radio frequency, so the price is also more expensive than the radio frequency anti-theft device.


The advantages and disadvantages of the RF anti-theft device are just the opposite of the acoustic magnetic anti-theft device. Because the radio frequency anti-theft device uses radio waves as the signal for transmitting and receiving, the radio frequency anti-theft device is characterized by low price and convenient installation. Because the RF anti-theft tag is a coil type, many coil items or electronic products with similar tag frequency will trigger the system and generate false alarms. Therefore, compared with the acoustic magnetic anti-theft device, it is easy to generate false alarms. The detection rate of the device is generally around 80%.

RF system supermarket anti-theft device also has two kinds of hard tags and soft tags. It can also protect most of the goods in the supermarket. The sending and receiving distance can't be more than 1.2 meters. The other is that the RF system is shielded by metal foil paper. If the label is close to or pasted on the metal foil, the label will be invalidated, causing the system to miss the report, but these shortcomings can also be overcome.
