How to choose a suitable anti-theft system for electronic goods


1. System design
According to the layout and format of the shopping mall, choosing the correct system design scheme can achieve the best anti-theft effect and price ratio. Generally speaking, convenience stores, specialty stores, specialty stores, including clothing stores, audio-visual stores, and other stores with a business area of several hundred square meters, adopt the method of total export inspection and protection. However, large-scale comprehensive supermarkets, shopping centers, warehouse-style shopping malls, etc., are suitable for the use of cashier channel detection and protection methods. In both ways, the installation of anti-theft can be invested in the required business area, including equipment investment and loss prevention personnel, within a certain range, and the deterrent effect of anti-theft can be significantly increased. According to our experience, the investment of EAS anti-theft equipment per square meter of business area is controlled within 100 yuan. The larger the business area, the lower the equipment investment cost.
2. An important index to measure the performance of EAS equipment
The physical technologies used by EAS are divided into the three most commonly used types: radio frequency technology, acousto-magnetic technology, and electromagnetic technology. But not every physical technology is perfect, they have their inherent advantages and disadvantages. The detection rate and false alarm rate of the system are the two most important indicators to measure the performance of the technology and equipment. The detection rate refers to the ability of the EAS detection antenna to detect tags of a certain size within the designed installation width. The field distribution of the detection antenna is not uniform, and the detection rate of a normal system should be above 85%. The concept of false alarm rate has always been relatively vague. The explanation that is usually more suitable for shopping malls is: the number of false alarms caused by the environment or non-anti-theft tag objects in a unit of time under normal use of the detection antenna. In daily real life, an object with similar physical characteristics as an electronic anti-theft tag can often be found, and when the object passes through the detection antenna, a false alarm will inevitably be generated. In terms of the false alarm rate, shopping malls are often the easiest to be misled by equipment suppliers. With any technical EAS, it is impossible for the false alarms to be zero.
3. Advanced technology
To improve the absolute indicators of EAS detectors: that is, the detection rate is high, but the false alarm rate is low. At present, only EAS with smart digital technology can meet the requirements. This technology uses the analog signal received by the EAS antenna to perform high-speed A/D conversion, and the digital signal is processed by a computer, using artificial intelligence to identify the characteristics of the electronic tag. Only EAS with this intelligent digital technology can be used in various electromagnetic environments, which can improve the detection rate of the system and reduce false alarms. Only a few companies in the world currently have this technology. It is very gratifying that products with this technology are now also launched in China. This has brought good news to our entire retail industry in terms of commercial loss prevention.
Fourth, price factors
The price of EAS equipment is a very important factor. Now more and more self-selected shopping malls have considered EAS as a necessary facility, and they are also very concerned about the investment in EAS equipment and the return on the actual anti-theft effect. The current EAS equipment leasing plan for chain commercial enterprises can meet the needs of most chain commercial enterprise customers for commercial loss prevention facilities. It is also a concrete manifestation of the company's corporate mission to contribute to the domestic retail industry.
5. Compatibility of system technology
When we choose EAS equipment, don't forget its compatibility. There are two aspects to pay attention to here: First, if we are a commercial chain company, we must pay attention to the use of EAS devices with the same physical characteristics in each store. This will bring convenience and benefits to future label purchases, system maintenance, and upgrades. Second, when shopping malls use EAS equipment, one of the most important expenses is the long-term purchase of consumable materials. We must remind all merchants to pay attention to the choice of EAS technology compatibility to avoid the market monopoly of anti-theft tags and the increased cost of anti-theft tags.
6. Comprehensive supporting capabilities of the system
When choosing an EAS supplier, you must consider its comprehensive system capabilities. Because the entire EAS system, in addition to the detector, also includes a soft label decoder and various types of soft and hard labels. If the performance of the soft tag decoder is not good, the soft tag may not be killed accurately, and the customer will cause an alarm when the antenna is detected by the EAS, which will bring embarrassment and unfavorable situation to the customer and the merchant. The decoding speed of the soft label decoder is also a comprehensive consideration. A good soft label decoder should have the characteristics of scanning frequency bandwidth, high decoding height and fast decoding speed. Soft labels are still mainly imported. Domestic soft labels with some physical technologies have begun to be produced, and their performance needs to be substantially improved. When shopping malls, pay attention to the phenomenon of shoddy goods. The performance indicators of hard tags are often overlooked. When purchasing, pay attention to its tensile strength and Q value, as well as whether the steel nails are easily rotated out (mainly for non-slotted light nails). Hard labels with poor quality are more likely to be destroyed. Therefore, when selecting an EAS equipment supplier, its comprehensive system capabilities should be considered.
Seven, product standards and quality system
The EAS industry is a small but emerging industry. Some manufacturers, especially some domestic manufacturers, often ignore their product standards and quality systems. The products they produce have neither product standards nor quality assurance. Who dares to use such products? When we choose EAS, we can no longer blindly listen to the supplier's self-introduction. We must examine its product standards and quality system, including the quality system in terms of engineering installation.
8. Experienced and long-term stable and high-quality service system
Merchants who have used EAS know that EAS is a project with relatively high service requirements. The equipment cannot work normally, which immediately leads to an increase in the loss of goods. Misreporting of equipment can cause embarrassment to customers, and serious consequences such as customer complaints, media exposure, and legal proceedings to merchants.
I hope you can better choose the anti-theft system for electronic goods after getting to know it, and buy your favorite products.
