With the continuous development of the retail industry, open price and self-experience have become a favorite shopping method, but while merchants provide customers with this convenient shopping experience, product safety issues are also an important issue that plagues merchants. Because of a completely open shopping space, it is inevitable that products will be lost. Especially some small and refined products are often not of low value.
To deal with this problem, the first thing that merchants think of is to install monitoring, but monitoring is only a tool for finding problems afterwards, and cannot be processed in time, because there is not so much manpower and energy to always stare at the monitoring screen to see which customer has the problem. It can only be searched after the fact, but at this moment the product has been lost.
The most effective way to deal with it now is to install an electronic detection system for EAS products. This kind of product has timeliness. If there are unsettled products passing through the detection channel at the door, they can promptly report to the police and remind the sales personnel of the store.
Nowadays, there are two main types of supermarket security doors that are used a lot on the market. One is the frequency 8.2Mhz (commonly known as the radio frequency door), and the other is the 58khz (
acousto-magnetic security door). So which frequency is better? How should we choose? Let me give you a brief analysis from the following points:
1. At the technical level, most RF gates now use analog signals, while acoustic magnetic gates use digital transmission technology. Therefore, acoustic magnetic gates are relatively more sophisticated in signal recognition. The equipment is not simply interfered by other unrelated signals. Equipment stability is better.
2. Detect the channel width, now the effective maintenance of the radio frequency door, the channel interval soft label 90cm-120cm, hard label 120-200cm, acoustic magnetic door detection interval soft label 110-180cm, hard label 140-280cm, relatively speaking, acoustic magnetic door detection The interval should be wider, and the shopping mall installation will feel wider.
3. The types of products to be maintained. Because of the working principle of the radio frequency system, radio frequency tags are simply interfered and shielded by signals from the human body, tin foil, metal, etc., resulting in the inability to achieve maintenance functions on products of this type of material, while the sound and magnetic equipment is relatively It's much better, even in products made of tin foil and other raw materials, it can also have a theft-proof effect.
4. In terms of price, because of the earlier use of radio frequency equipment, the price is lower than that of acousto-magnetic equipment. However, with the continuous improvement and rapid development of acousto-magnetic equipment in recent years, the cost is gradually decreasing. Now the price distance between the two equipment is gradually increasing. Zoom out.
5. Appearance display effect and raw materials. Because of some problems in radio frequency equipment, there are fewer and fewer manufacturers investing in radio frequency equipment. Radio frequency equipment is not as good as acousto-magnetic equipment in terms of product innovation or development and implementation. .
