Electronic commodity anti-theft systems have various forms and deployment scales to meet specific business security requirements. When choosing an EAS System for your retail environment, you need to consider the following eight factors:
The detection rate refers to the average detection rate of undemagnetized tags in all directions in the monitoring area, and is a good performance indicator to measure the reliability of the EAS system. A low detection rate usually means a high false alarm rate. For the three most commonly used technologies in EAS systems, the latest acousto-magnetic technology has a benchmark average detection rate of over 95%, radio frequency systems are 60-80%, and electromagnetic systems are 50-70%.
Tags from different EAS systems often cause false alarms. Tags that are not properly demagnetized can also cause false alarms. The high false alarm rate makes it difficult for employees to intervene in security incidents, resulting in conflicts between customers and stores. Although false alarms cannot be completely eliminated, the false alarm rate is also a good system performance indicator.
Interference will cause the system to automatically issue an alarm or reduce the detection rate of the device. The alarm or non-alarm has nothing to do with the Anti-Theft Tag. This situation may occur in the event of a power outage or excessive environmental noise. Radio frequency systems are particularly vulnerable to such environmental interference. Electromagnetic systems are also susceptible to environmental interference, especially magnetic interference. The acousto-magnetic EAS system has strong resistance to environmental interference due to the use of computer control and unique resonance technology.
The shielding effect of metal can interfere with the detection of safety tags. This role includes the use of metal items such as food, cigarettes, cosmetics, medicines, and metal products such as batteries, CD/DVD, hairdressing supplies, and hardware tools. Even metal shopping carts and shopping baskets can protect the security system. Radio frequency systems are particularly vulnerable to shielding, and large-area metal objects can also affect electromagnetic systems. Since the acousto-magnetic EAS system uses low-frequency magnetoelastic coupling, it generally only affects all-metal products, such as cookware, and is very safe for most other products.
A robust EAS system needs to consider the safety requirements of stores and the needs of retail traffic. A system that is too sensitive will affect shopping mood, while a system that is not sensitive enough will reduce the profitability of the store.
Retail goods can generally be divided into two categories. One is soft goods, such as clothing, footwear and textiles, which can be protected by EAS hard tags and can be reused. The other category is hard goods, such as cosmetics, food and shampoo, which can be protected by EAS disposable soft labels.
EAS Soft Tags and hard tags are an indispensable part of any EAS system, and the performance of the entire security system also depends on the correct and appropriate use of tags. It is important to note that some labels are easily damaged by moisture, and some cannot be bent. In addition, some labels are easy to hide in the box of the product, and some will affect the packaging of the product.
In the entire safety link, the reliability and convenience of the EAS degaussing device is also an important factor. The advanced EAS degaussing device uses non-contact degaussing, which maximizes the efficiency of the cash register and speeds up the passing speed of the cashier channel.
