First of all, let us briefly introduce the composition of the clothing anti-theft device, mainly by three parts:
1. The detection device is the detection gate that forms the protection channel installed at the entrance and exit of the shop.
2, clothing anti-theft magnetic buckle, clothes on the button
3, degaussing release device, used to solve the anti-theft buckle tool
Why does the anti-theft buckle pass the detector at the door and alarm? Because the clothing security door forms a fixed frequency magnetic field in the range of about 2 meters, the general radio frequency equipment is 8.2MHZ, the acoustic magnetic equipment is 58KHZ, and there is a coil or magnetic rod inside the clothing anti-theft buckle, its frequency is the door and the door. The security door is consistent, and when the anti-theft buckle passes through the magnetic field of the door, it will sense each other to trigger an alarm.
Understand the simple principle of clothing anti-theft, we will analyze the reasons for the poor use of anti-theft devices in some stores:
1. Electromagnetic signal interference, because the clothing security door is a natural frequency magnetic field, it is bound to be affected by some similar signal sources, mostly large metal frames, high-power appliances, such as large air-conditioning compressors, freezers, inverter elevators, Led light source power adapter, etc., in order to make the anti-theft device work stably, we must conduct a survey of the surrounding environment when installing the clothing anti-theft device, try to avoid possible interference sources.
2, power supply interference, there will be electromagnetic pulse interference on the power line, so the line that supplies power to the clothing anti-theft device should not share a line with other electric appliances. It must be independently powered from the distribution box, and the ground wire is required to be in good contact.
3, the same type of equipment interference, in the mall, almost all stores have anti-theft equipment installed, but the equipment of different manufacturers have different modes of transmitting and receiving signals, if the shop equipment is very close, you need to phase the equipment Synchronization with the launch cycle, otherwise it will affect each other and the device has problems.
4, there is also a major problem is the environmental factors of their own stores, some stores are very large, the store door is also very empty, there is no electrical interference or anti-theft buckle next to the anti-theft device, the channel distance of the anti-theft device installation Very wide, the detection effect is also very good, but there are some small shops, the store space is limited, the goods at the store door are also full, the goods with magnetic anti-theft buckle and the anti-theft device are only a dozen or twenty centimeters away, and some even Tightly squatting, all within the detection range of the equipment, the anti-theft device will inevitably report false alarms. At this time, the good solution to solve the problem is to remove the goods with anti-theft buckles by more than 1 meter, or within one meter. Do not nail the anti-theft buckle, otherwise the device can't work normally, because the sensitivity is lowered, there is no alarm when the label passes through the channel. If it is not turned down, the device will always report false alarms. If you want the anti-theft device to be blinded to the anti-theft around you, and it will not be able to buckle the eyes of the normal anti-theft.
