In modern society, opening a supermarket, I think it is almost indispensable to install a supermarket anti-theft system, because the anti-theft function of the supermarket anti-theft system in the supermarket is indispensable. So far, there is nothing to replace. But when the supermarket owners go to buy a supermarket anti-theft device, the salesperson will also ask you whether you want to choose an AM anti-theft system or a RF anti-theft system. How do you choose? The following suggestions will been given by Etagtron to the supermarket owners.
First of all, we must clearly know the difference between the AM anti-theft system and the RF anti-theft system.
1. From the perspective of price, the RF anti-theft system is cheaper than the AM anti-theft system.
2. From the aspect of anti-interference ability, the anti-interference ability of the RF anti-theft system is far less than that of the AM anti-theft system. The RF anti-theft system is extremely vulnerable to metal shielding (so the detection rate of the RF anti-theft system is not as good as that of the AM anti-theft system. High), metal objects nearby can easily interfere with the RF anti-theft system.
3. From the perspective of false alarm rate, the false alarm rate of the AM anti-theft system is extremely low, while the false alarm rate of the RF anti-theft system is slightly higher.
Secondly, when we understand the difference between the AM anti-theft system and the RF anti-theft system, we will consider whether to install the AM anti-theft system or the RF anti-theft system based on the situation of our own supermarket.
1. If your supermarket is a small supermarket with a relatively small area and not much passenger flow, then you can choose to install a RF anti-theft system, because a small supermarket requires fewer types of anti-theft products, so use a good-performance RF anti-theft The device can deal with the anti-theft problem. 2. If your supermarket has a large area and a large number of customers, it is better to install a sound and magnetic anti-theft system, because large supermarkets have more varieties of goods to be anti-theft, and supermarket anti-theft with a stronger detection rate is required. System to guard against theft.
3. Another point is the impact of the supermarket itself and the surrounding environment. Because the RF anti-theft system is very susceptible to metal interference, if you want to install the RF anti-theft system, there should be no large electronic equipment around the installation point of the anti-theft door in the supermarket. This will greatly affect the detection frequency of the tag and the accuracy of the detection.
4. If you have also installed a RF anti-theft system in the shops around your supermarket, you'd better not install a RF anti-theft system, because the use of the two together will greatly affect the detection performance.
Finally, consider installing a RF anti-theft system or an acoustic-magnetic anti-theft system. It is best to listen to the suggestions of professional supermarket anti-theft system technicians in the district and let them recommend a supermarket anti-theft system suitable for your supermarket. After all, it is a specific analysis in many cases. , And we need professional technicians to teach you how to use these supermarket anti-theft systems, so that the supermarket anti-theft system can exert its maximum effect.
