Can the Supermarket EAS Anti-theft System Really Work? [Bohang China]
Supermarket anti-theft devices are inevitable in the development of the times. Today's consumer demand is a lot. Unlike before, we buy very few things every month, buy household items for almost a year, and so on. Nowadays, almost everything has to be purchased, so there is a lot of demand for shopping scenes. The requirements for supermarket anti-theft devices are very high, and the operators are relieved of a lot of pressure. Speaking of supermarket anti-theft devices, many people believe that it is the kind of device used by inspectors to detect the presence or absence of metal objects, also known as metal detector doors. But today, the supermarket anti-theft device is also called the anti-theft antenna. It uses the principle and technology of acoustic magnetic induction or radio frequency induction to protect the goods in the supermarket from being stolen. So can the supermarket anti-theft device really play the role of anti-theft?
First we understand the principle of the supermarket eas anti-theft system. The supermarket anti-theft device is generally composed of a transmitter and a receiver. The transmitter transmits the scanning band and forms an area between the transmitting antenna and the receiving antenna. The receiver then brings the frequency back, and uses the principle of electromagnetic wave resonance to detect this. Whether there is a valid tag in the area, if it is present, an alarm is triggered, and a "drip" alarm sounds.Let's take a look at how specific theft is.
A complete set of supermarket anti-theft security door system consists of anti-theft antenna, anti-theft tag, nail remover / decoder. It mainly uses the principle of magnetic field induction to prevent theft. The anti-theft antenna installed at the door has a magnetic sensor with an alarm function. If the label installed on the product has not undergone regular degaussing or nail removal operation, the supermarket eas anti-theft system will emit a “drip” alarm sound when passing through the supermarket door. Only after the customer pays the purchased product, the cashier can perform the nail removal operation on the hard label on the product, or degauss the soft label attached to some products, the customer can take the purchased product smoothly through the supermarket. The anti-theft antenna for export.
After understanding the working principle of the supermarket eas anti-theft system, I believe that everyone is beginning to worry about the performance of the product. I want to know if the product can accurately report the alarm during the work process, whether it will be missed/false positive. Now the supermarket anti-theft device uses a high-end DSP processor, special anti-power interference technology, to achieve high stability, high alarm, the detection rate of 99%, almost zero false positives, false negatives. Since different anti-theft antennas are used with different anti-theft tags, the width of the detection area is different. Therefore, when installing the anti-theft device to the customer, the professional will be arranged to conduct on-site investigation, and the final anti-theft solution will be given according to the actual situation of the shop. Plays a good anti-theft effect.
