AM EAS Anti-theft system Manufacturers

EAS is also known as an electronic product aft system, is one of the currently used commodity security measures in the retail industry.

The so-called acousto-magnetic is a resonance phenomenon generated by the principle of tuning forks. When the frequency of the transmitted signal (alternating magnetic field) is consistent with the oscillation frequency of the acousto-magnetic tag, the acousto-magnetic tag will cause resonance similar to the tuning fork and generate a resonance signal (alternating magnetic field); After the receiver detects 4-8 consecutive (adjustable) resonance signals (once every 1/50 second), the receiving system will issue an alarm.

The library anti-theft system is somewhat different from the clothing and supermarket anti-theft systems, and the system configuration is more complicated. Therefore, the problems that can be solved in the clothing and supermarket anti-theft systems may not be solved in the library anti-theft system. And most library anti-theft systems belong to electromagnetic wave systems, so the principle is completely different. Here are some problems and solutions that library anti-theft will encounter.

When many customers choose anti-theft devices, they think that all anti-theft devices have similar performance, so which one is cheaper to choose! As everyone knows, the quality of the anti-theft device mainly depends on the motherboard. It seems that the appearance is similar, but because of the different motherboards, the performance varies greatly! The customer's biggest feeling about the quality of the anti-theft device is whether the anti-theft device can work normally after it is installed! If you spend a lot of money to install it but it doesn't work, you will lose a lot! In the end, you can only spend another sum of money to re-purchase! This seemingly small probability thing is always happening!
