Selection of sound and magnetic anti-theft devices

I believe that many merchants will be confused when purchasing acousto-magnetic anti-theft equipment, because this clothing anti-theft device is not available everywhere, after all, I may have heard from friends around me, but which brand has good quality and which brand of service. Well, many customers are not very clear. What problems should be paid attention to when purchasing acousto-magnetic anti-theft equipment?
The so-called acousto-magnetic system uses the resonance phenomenon generated by the tuning fork principle to complete the operation with almost zero false alarms. When the frequency of the transmitted signal is consistent with the oscillation frequency of the acousto-magnetic tag, the acousto-magnetic tag is similar to a tuning fork, which will cause resonance and generate a resonance signal; when the receiver detects the resonance signal for 4-8 consecutive times, the receiving system will issue an alarm. Based on this alarm feature, the use of acoustic and magnetic anti-theft equipment greatly reduces false alarms, and the interval between door detection devices is relatively wider. Generally, the interval between the devices is about 1.2-3 meters in the maintenance channel (the anti-theft labels are different). Of course, The price is also relatively high, generally around 2000-5000 yuan per unit. High-end shopping malls, brand stores, and image flagship stores are more commonly used.

If you have an understanding of the acoustic and magnetic anti-theft equipment, the following should be paid attention to is the product quality and after-sales service. With the rapid development of the Internet, more and more businesses have also put acousto-magnetic anti-theft devices on Taobao, Tmall and Jingdong for sale. The biggest advantage of selling online is that the price seems to be cheaper. However, Xiao Bian does not recommend online shopping, but requires professional construction personnel to carry out professional installations. As long as the equipment is debugged according to the magnetic field environment of each store’s specific site, it can be used more stably; once there is a problem during the installation process, it is difficult to After a phone call, it brought endless troubles to the buyer, no refund, no repair, no use.
