How many clothing anti-theft systems should be installed? [Bohang]
The bosses of many clothing stores have to ask when consulting: How to design the door distance of our clothing store, it is more appropriate to install several antennas. The number of installations of the anti-theft door is quite sophisticated. It is necessary to understand the actual situation before designing the most correct installation plan.
The door distance of the anti-theft device is an important technical indicator for installing the antenna. Generally speaking, 90-200 cm is a common installation door distance. The installation distance will be determined according to the detection distance of the antenna and the situation of the store. Usually, the detection distance will be reduced during the design and installation to install, because the anti-theft door is in the reduced detection range, the anti-theft device works in an ideal state, and the detection accuracy is accurate. Will be higher. Of course, in the end every clothing store exactly how wide to be installed, but also the janitor from the size of the electromagnetic field surrounding environment is satisfactory, clothing store entrance location aesthetic requirements and so on, so the installation is best to let a professional engineer design and installation.
Under the premise of the same electromagnetic field environment and the same effect, the difference of the gate distances of different detection antennas can be used as a parameter to judge the advantages and disadvantages. Any EAS system detection antenna has an alarm dead zone within its detection range, and the same tag signal When entering the detection range in different directions, the alarm dead zone of the antenna is different. I think the smaller the range of the blind zone, the better the working state of the system. Of course, for the thief, no matter how big the blind zone is, they dare not hold it. With a good luck, I will try my best.
