70% of the effect of the EAS anti-theft system is used for deterrence. According to the layout and business type 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, professional stores, including clothing stores, audio-visual stores and other stores with a business area of several hundred square meters, adopt the general export inspection and protection method. For large-scale comprehensive supermarkets, shopping centers, warehouse-style shopping malls, etc., it is suitable to adopt the cashier channel detection and protection method. Both methods can control the anti-theft investment for the unit business area, including the investment in equipment and loss prevention personnel, within a certain range, and the deterrent effect of anti-theft can be significantly increased.
2. Important indicators to measure the performance of EAS equipment
The physical technologies used in EAS are divided into three most commonly used types: radio frequency technology, acousto-magnetic technology, and electromagnetic technology. But not every physical technique is perfect, and they all have their inherent advantages and disadvantages. The system's detection rate and false alarm rate of tags are the two most important indicators to measure the performance of the technology and equipment. The detection rate refers to the detection ability of the EAS detection antenna to a certain size of the label within the design 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 positive rate has been relatively vague. The explanation that is usually more suitable for shopping malls is: the number of false alarms caused by the influence of the environment or non-anti-theft tag objects within a unit of time under normal use of the detection antenna. In daily real life, it is often possible to find objects with similar physical characteristics to electronic anti-theft tags, and when the object passes through the detection antenna, it will inevitably generate false alarms. On the concept of false alarm rate, shopping malls are often the most vulnerable to misleading equipment suppliers. It is impossible for any technical EAS to have zero false positives.
3. Technological advancement
To improve the absolute index of the EAS detector: that is, the detection rate is high and the false alarm rate is low. At present, only EAS with intelligent digital technology can meet the requirements. This technology adopts the high-speed A/D conversion of the analog signal received by the EAS antenna, and performs computer processing on the digital signal, and uses 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 reduce false alarms while improving the detection rate of the system. At present, only a few companies in the world have this technology. It is very gratifying that products of this technology are now also launched in China. This has been a boon for our commercial loss prevention business as a whole.
Four, the price factor
The price of EAS equipment is a very important factor. Now more and more self-selection shopping malls have considered EAS as a necessary facility, and they are also very concerned about the return on the investment of EAS equipment and the actual anti-theft effect. The EAS equipment rental plan for chain commercial enterprises launched now 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 purpose of contributing to the domestic retail industry.
5. Compatibility of system technology
When we choose EAS equipment, don't forget its compatibility. Here are two aspects to pay attention to: First, if we are a commercial chain company, we must pay attention to the selection of EAS equipment 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 very 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 monopoly phenomenon in the anti-theft label market and increase the cost of anti-theft labels.
6. Comprehensive supporting capabilities of the system
When choosing an EAS supplier, its comprehensive system supporting capabilities must be considered. Because the whole 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 label decoder is not good, the soft label may not be accurately killed, and the customer will cause an alarm when the antenna is detected by EAS, which will bring embarrassment and disadvantages to customers and businesses. The decoding speed of the soft label decoder is also a comprehensive consideration. A good soft label decoder should have the characteristics of wide scanning frequency, high decoding height and fast decoding speed. Soft labels are still mainly imported, and some physical technology soft labels have been produced in China, and their performance needs to be substantially improved. When shopping in shopping malls, pay attention to the phenomenon of shoddy goods. Hard-label performance metrics are often overlooked. When purchasing, pay attention to its tensile strength and Q value, and whether the steel nail is easy to be rotated out (mainly for smooth nails without grooves). Hard tags with poor quality are relatively easy to be damaged. Therefore, when choosing an EAS equipment supplier, its system comprehensive supporting capabilities should be considered.
Seven, product standards and quality system
The EAS industry is a small and emerging industry. Some manufacturers, especially domestic ones, tend to ignore their product standards and quality systems. The products they produce have neither product standards nor quality assurance. Who would dare 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 of engineering installation.
Eight, with experience 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. Equipment not functioning properly immediately brings increased loss of merchandise. False alarms on equipment can cause embarrassment to customers at least, and serious consequences such as customer complaints, media exposure, and legal proceedings to merchants.
I hope you can better choose the electronic product anti-theft system and buy your favorite products after understanding.
