How to correctly choose clothing anti-theft access control equipment?

Clothing anti-theft doors are no longer a rare anti-theft device. Almost every shopping mall clothing store will see various types of anti-theft doors. So how to choose anti-theft doors? Below, we will briefly introduce several methods for choosing a clothing anti-theft door.

1. To understand a product, we first need to have a general understanding of the working principle of clothing anti-theft devices. Currently, all anti-theft devices on the market mainly use detection antennas installed at the main entrance and exit of the store, forming a protective channel with a width of about 1.2-2.2 meters. A fixed magnetic field is formed within the channel range, and then an electronic tag corresponding to it is added to the product to be protected in the store. When the labeled product passes through the protective channel, an induction alarm is triggered; Customers who make normal payments for purchased goods can use a dedicated demagnetization device to demagnetize the electronic tag at the checkout counter, and then the goods can be taken out of the store normally.

2. What are the main types of clothing anti-theft products currently available on the market? At present, there are mainly two types of devices based on frequency: 8.2MHz and 58KHz, also commonly known as radio frequency and acoustic magnetic anti-theft systems. What are the characteristics and differences between the two types of products? RF equipment appeared earlier in China compared to acoustic and magnetic equipment, and its price is relatively cheap. The general market price is about 800 to 3000 yuan per unit (depending on the motherboard type and rack material). Due to technical defects, the installation and detection distance of the equipment is not wide. Generally, the effective detection distance based on the tag type is 80cm-2 meters (depending on the size, quality, and motherboard of the electronic tag used). During use, it is easily affected by interference from large metal frames, LED light power adapters, children's rocking machines, Ethernet cables, active speakers, etc., and the equipment is prone to false alarms and missed alarms. Given this situation, the current main users are small shops, street side shops, and shops with low anti-theft requirements.

3. The so-called Acoustic Magnetic (AM) system utilizes the resonance phenomenon generated by the tuning fork principle to achieve almost zero false alarms. When the frequency of the emitted signal (alternating magnetic field) is consistent with the oscillation frequency of the acoustic magnetic tag, the acoustic magnetic tag, similar to a tuning fork, will resonate and generate a resonance signal (alternating magnetic field); When the receiver detects 4-8 consecutive (adjustable) resonance signals (once every 1/50 second), the receiving system will issue an alarm. Based on this alarm feature, the use of acoustic and magnetic devices greatly reduces false alarms, and anti-theft electronic tags can be made smaller than RF systems. The distance for door detection installation is relatively wider, usually around 1.2-3 meters for protective channels (suitable for different anti-theft tags). Of course, the price is relatively higher, usually around 2000-6000 yuan per unit. High end shopping malls, brand specialty stores, and image flagship stores are commonly used.

4. After understanding the principles of two types of devices on the market, I have gained a general understanding of the devices. The next thing to focus on is product quality and after-sales service. With the rapid development of the internet, more and more businesses are selling clothing anti-theft devices on Taobao, Tmall, and JD.com. The biggest advantage of online sales is that the price seems cheaper. However, based on experience, we do not recommend online shopping because this product is not like a TV, which can be used simply by plugging it in at home. But it requires professional construction personnel to carry out professional installation. Only equipment that has been debugged for the specific magnetic field environment of each store can be used more stably.

Zui suggests that when choosing clothing anti-theft equipment, in addition to paying attention to price, you should also pay attention to the quality of the product and after-sales service. What kind of service is provided, whether it is simply providing telephone consultation service or on-site service.
