◆How does the EAS commodity electronic loss prevention system work?
Generally speaking, the detection antenna is installed at the entrance and exit of the shopping mall to form a warning channel and does not affect the passage of customers; the anti-theft label is attached to the product, and the cashier removes the anti-theft label when the customer purchases the product; The tagged goods will alarm when they pass the detection antenna.
EAS commodity electronic loss prevention system includes the following components:
Detection antenna: including transmitting antenna and receiving antenna, used to generate warning field.
Anti-theft tags: including hard tags and soft tags, attached to the product, enter the antenna warning range, the antenna will alarm.
Decoding equipment: including hard label unlocking device and soft label decoder, used to remove anti-theft labels on commodities.
◆We have installed surveillance and many security arrangements are not effective. Can EAS catch the thief? Can I reduce my product loss rate? How much can be reduced?
Install video surveillance and arrange security personnel to patrol the premises. These loss prevention measures have been commonly adopted in retail stores. In fact, there are certain flaws and loopholes in the single-sided use of such anti-loss measures of the nature of air defense. For example, the tight surveillance environment caused by the overly strict civil defense and densely-packed cameras can easily make shopping malls feel unfriendly to customers; surveillance is prone to camera blind spots, coupled with the increasingly sophisticated and sophisticated techniques of modern thieves, so in the heyday of shopping malls It’s easy to guard against and so on. The EAS system uses technical means to give goods a kind of self-defense ability, so that the loss prevention measures are implemented on the concept of self-protection of goods, which can accurately and effectively prevent the theft of goods and improve the relationship between shopping malls and customers. Therefore, the EAS system is used as a material An important means of prevention has now become a necessary budget for loss prevention in major retail stores.
The number represented by the loss rate of goods can never be steadily reduced by relying on a mere loss prevention method. At present, the domestic retail industry loses 25 billion goods a year. Each retail store has its own loss prevention index, and 1.1% is already a very good index. In the past, retail stores were at most a security department, but now every family has its own loss prevention department. This is more than just a name change. We must explain that loss prevention management in the retail industry is a relatively complex subject, and it requires the comprehensive application of various loss prevention measures and scientific management to achieve a better effect. We will go all out to make outstanding contributions to your loss prevention management with high-quality EAS system and corresponding professional services.
◆How to make purchase evaluation for so many brands? Which is cheap and easy to use?
There are many EAS brands in China. Given their high technical content, there are really a bunch of suppliers who offer quotations, and procurement evaluation will be a very difficult thing. With many years of experience in operating the EAS system, here are some suggestions:
1. At present, there are two main types of EAS systems used in domestic retail owners: acousto-magnetic systems and radio frequency systems. There are machines with imported and domestic technology respectively. Acousto-magnetic systems are expensive and have corresponding patented technology, while various machines with radio frequency systems with 8.2MHz as the main frequency flood the EAS market, with mixed results.
2. Any kind of EAS system has technical defects, and there is no perfect machine. For example, the radio frequency system has the problem of metal shielding.
3. Purchasing EAS system takes good quality and stable performance as the first element, followed by the price advantage. Although we have built a very good procurement platform in the form of the first domestic EAS alliance and can achieve very beautiful prices, we still do not advocate vicious competition from suppliers. EAS products have considerable technical content, and a certain profit is an important prerequisite for suppliers to provide high-quality technical services.
4. In the EAS system, the technical content of the detection antenna is high, so the purchase of the detection antenna needs to be cautious, and the core technology of the receiving board, door distance, stability and other indicators need to be investigated; while the technical content of the decoding device and the anti-theft tag is relatively low. Said that the purchasing attitude is relatively loose. Decoding equipment mainly examines the decoding height, the strength and stability of the unlocking device, and the anti-theft label mainly examines the strength, appearance, resurrection rate and stability of the soft label.
5. Relatively speaking, it is easier to choose imported machines for detecting antennas. Although the price is expensive, the performance and quality will be better; and for domestic machines, we suggest to take cost-effectiveness as the key element, and the same or similar quality should be low price, the same or Similar prices take high quality. Through simple machine field tests and comparisons, it is easy to get an intuitive understanding. If there are difficulties in the purchase of decoding appliances and anti-theft labels, they can also be compared.
◆Is it okay to buy accessories and equipment separately? Is it worth the high cost to buy imported machines? Can domestic machines be substituted?
In the previous question, we have already mentioned that in the EAS system, it is easier to purchase imported equipment with relatively stable and excellent quality for the purchase of the high-tech detection antenna part. We believe that according to the use requirements of the store and the arrangement of the loss prevention budget, we can give priority to the selection of imported equipment for the detection antenna. On the basis of the price disparity, we can consider the use of high-quality domestic equipment; and in the decoding equipment, anti-theft For the purchase of labels, we can use domestically-made equipment and accessories, but we only need to choose the best cost-effective thing from a variety of different categories.
In terms of detecting the quality of antennas, it is difficult for domestic machines to replace imported machines. At present, domestic detection antennas in the EAS industry still have a large number of receiving motherboards with analog signal technology as the main body, and the application of digital technology is still in its infancy; while most of the digital intelligent processing of imported detection antennas has been done quite well, we represent Take the crosspoint detection antenna motherboard technology of the Dutch top-pole radio frequency technology as an example and analyze it to get an intuitive understanding:
This device is not comparable to domestic machines in terms of the detection range of the detection antenna, the resolution of the identification of the anti-theft tag signal (which can be called secondary identification technology), and the speed and stability of the identification of the anti-theft tag signal. , And these three indicators are very important procurement elements for a customer who understands EAS products and uses more demanding requirements.
◆Which machine has fewer false positives and false negatives? Which machine works stably?
Any kind of EAS system may have false alarms and false alarms, and the reasons for these two abnormal phenomena are very complicated, which may be the surrounding electromagnetic field interference, misoperation, lack of the ability of the motherboard technology to deal with interference, etc., so When we purchase EAS, we should adopt the principle of selecting the best in all important indicators of the detection antenna. Of course, on-site inspection and test comparison is the easiest way to identify.
We give a more accurate explanation of the two concepts of false positives and false negatives:
In the case of electromagnetic field interference, the EAS system may have abnormal working conditions: when there is no anti-theft tag signal of the allowed frequency of the system to pass through the working range of the equipment, the system still emits an audible and visual alarm, which is called system self-sounding. It is also called false alarm; when the anti-theft tag signal of the allowed frequency of the system passes through the working environment of the device, the system does not work, which is called system false alarm.
Generally, when purchasing the EAS system, merchants like to use these two concepts as a procurement standard. In fact, these two concepts only represent a state of use, and they are closely connected with the merchant’s attitude toward using the system. Make a clear judgment before using the system, and even if the judgment is clear, there is still a lot of room for misleading. If we are clear about these two concepts, then the technical indicators for testing antennas based on these two concepts are easier to judge the procurement ruler, and it is easier for us to gain intuitive understanding.
◆How wide can the anti-theft antenna be installed? Will there be blind spots in the alarm?
Door distance is an important technical indicator for detecting antennas. Generally speaking, 90cm is the most common installation door distance. Within the detection range of this distance, the working condition of the machine is ideal. Of course, how wide each store needs to be installed depends on whether it uses analog technology or digital processing motherboards, whether the surrounding electromagnetic field environment is ideal, and the aesthetic requirements of the entrance and exit of the store. Generally speaking, there is no clear figure to determine , Site survey is the best way to confirm the door distance. Under the premise of the same electromagnetic field environment and the same use effect, the difference between the gate distances of different detection antennas can be used as a parameter to judge the pros and cons.
Any EAS detection antenna has an alarm blind zone within its detection range, and when the same tag signal enters the detection range in different directions, the antenna’s alarm blind zone is different. The smaller the blind zone is, the better the system will work. . Of course, for thieves, no matter how big the blind spot is, they dare not try to “ring” with a fluke.
◆Is there no need to be afraid of thieves after buying an EAS system? Does every product have to be affixed with anti-theft labels?
The EAS system is an indispensable method in loss prevention management. Its intimidation and self-protection capabilities have a huge impact on your loss prevention management. However, the EAS system still needs to be used in conjunction with other loss prevention measures. Objectively speaking, the EAS system is currently the best hardware equipment and the best material defense method in loss prevention procurement. And your loss prevention management also needs to be diligent and go all out to seek progress. Therefore, with the EAS system installed, we still have to wait for the thieves to regain profits from the loss of goods.
In the anti-theft label accessories of the EAS system, the hard label is a one-time investment and can be reused, and the soft label is a consumable. Because the purchase cost is not low, not every product needs to be affixed with an anti-theft label. Generally speaking, we choose High-priced small items. In view of the intimidation effect of the EAS system, the anti-theft label can be combined with virtual and real, sometimes and sometimes not, so as to achieve the lowest use cost and the best use effect.
