Why do doors of the same width have different numbers of supermarket anti-theft devices?

Many customers buy a supermarket anti-theft device for the first time, thinking that the store only needs to install a set of supermarket anti-theft device, one on the left and one on the right of the door. In fact, this is a misunderstanding! The number of sticks installed in the store is actually determined by the size of the store's facade and the detection distance of the anti-theft system.
Due to different systems and different styles of supermarket anti-theft devices with different anti-theft labels, the detection distance of the supermarket anti-theft devices will be affected. Taking an acrylic anti-theft device with a medium detection distance as an example, the detection distance without environmental interference:
1. DR anti-theft soft label: detection distance 1.6-1.8 meters

2. Small hammer anti-theft buckle: detection distance 1.8-2.0 meters

3. Big hammer anti-theft buckle: detection distance 2.6-2.8 meters
If the store products need to use soft labels, then the detection distance of the soft labels should be used to determine the installation distance before the two anti-theft devices. If a store facade is 1.6 meters wide, then only two anti-theft devices need to be installed. The distance of the security door is 1.6 meters. If a facade is 4.2 meters wide, then it is necessary to install 3 anti-theft devices, 2 mainframes, 1 auxiliary device, and the distance between the 2 supermarket anti-theft devices is 1.4 meters.
Due to the different scales of different supermarkets, clothing stores and other stores, the width of the facade is also different. In fact, the safest way is to consult a professional supermarket anti-theft device manufacturer, first tell us what store you are, how wide the door is, what is your budget, and what is nearby There is no interference source, etc., our salesman will give you the best installation plan based on your needs!
The performance of supermarket anti-theft devices produced by different manufacturers is different, which directly determines the installation distance of the anti-theft device. If you want to buy a supermarket anti-theft device with good performance at one time, you must remember to choose an industry-approved manufacturer! Hope this article helps you all!
