How to select the electronic anti-theft system?
Table of Contents
When purchasing electronic anti-theft system, we should pay attention to product performance, price and after-sales service. What factors must be considered by businesses when choosing EAS.
Which factors are the reference indexes for selection can be analyzed from three aspects: EAS performance, price and after-sales service.
Performance of electronic anti-theft system
At present, there are three electronic anti-theft systems with different principles in the market, namely, acoustic magnetic system, radio frequency system and electromagnetic system. The so-called different principles are actually based on the carrier media of electronic signals. For example, the carrier of radio / RF system is radio waves. Due to the different characteristics of signal carrier media, the performance of the system varies greatly.
System detection rate refers to the number of alarms when a unit number of effective labels pass through different positions in the system detection area in different directions. The detection rate of the ideal electronic anti-theft system should reach 100%, and the electronic anti-theft system that can be used can not reach the ideal value. The detection rate of electromagnetic wave system is generally about 50% to 70%, that of radio / RF system is generally 60% to 80%, and that of acoustic magnetic system is generally more than 95%, which is close to the ideal value.
The false alarm of the system triggered by the non anti-theft label is called system false alarm. It is an important performance index that is more concerned by businesses than the detection rate, because the alarm of the anti-theft system is the basis for the judgment of the staff of the mall. If other non labeled items trigger the system alarm, it will bring difficulties to the judgment and handling, and it is more likely to cause the conflict between customers and the mall. Limited by the principle, some systems still eliminate false positives despite taking some measures. For the radio / RF system, it may be disturbed by coil like objects and give false alarm. Electromagnetic wave system will be affected by magnetic and metal articles and give false alarm. The acoustic magnetic system uses the physical principle of resonance caused by the same oscillation frequency, so it is almost zero false alarm. Although the current common systems do not rule out the possibility of false positives, there are great differences between the principles. It is best to go to the mall where the electronic anti-theft system has been installed to understand the actual use.
The degree of shielding by metal objects. There are many kinds of commodities with metal objects in department stores and supermarkets. In addition, the mall also provides metal shopping carts and shopping baskets. The impact of these metal containing objects on the anti-theft system is mainly the shielding effect on the induction label, and the detection sensitivity of the detection device decreases, so the system will not send an alarm. The most seriously affected by metal shielding is the radio / RF system. The electromagnetic wave system is also affected by metals. The anti influence ability of the acoustic magnetic system is much better than the above two systems. The acoustic magnetic labels of common metal items in shopping malls can work normally, and only pure iron products can affect it.
Price of electronic anti-theft system
Generally, the price of the electronic anti-theft system is cheap, and the performance will be affected to a certain extent. Sometimes, choosing a system with good performance will be restricted by economic ability. Therefore, shopping malls should pay attention to the reasonable performance price ratio when choosing electronic anti-theft system. Since most of the anti-theft systems are imported products from abroad, the cost is relatively high. For many shopping malls, if affected by price factors, the step-by-step method can be considered. Large department stores can adopt local anti-theft methods in conditional floors or areas. Storage supermarkets may first consider anti-theft protection for some commodities.
After sales service includes: service response time, professional level of technicians, problem-solving ability, etc. If it is a cross regional operation, the after-sales service is unlikely to be well guaranteed. It is best to choose a system brand with good reputation in the region, fixed agents and professional technical maintenance personnel.
In addition to some objective factors, there are also some subjective factors that affect the popularization and use of anti-theft system. For example, the installation of anti-theft system is used to catch thieves; The anti-theft system cannot guarantee that 100% of the goods will not be lost; Using the anti-theft system, you can rest assured; The return on investment is not obvious, etc. There is also a unclear understanding of the performance of the system, such as detection rate, false alarm, shielding, export protection width, type and scope of protected commodities, etc. If the equipment is selected according to the above indicators, errors can be avoided and the role of anti-theft system can be played.
