Electronic commodity anti-theft system (EAS) has a variety of forms and scale of deployment, in order to satisfy a particular business security. In the retail environment for you to choose EAS system, the need to consider the following eight factors:
First, the detection rate
Detection rate refers to the monitoring area, in all directions of the average detection rate, degaussing label which is measured EAS system is reliable and a good performance. Low detection rate is often also means that the high rate of false positives. For EAS system, the most commonly used three kinds of technology in the near acoustic magnetic technology benchmark average detection rate is over 95%, rf system for 60-80%, electromagnetic is 50-70%.
Second, the rate of false positives
From different EAS label system often causes miss alarm. Without correct demagnetizing tag can also cause false alarms. High rate of false positives can make employees to intervene on security matters, then make the conflict between customers and stores. Although not completely ruled out false alarm, the rate of false positives and measure a good indicator of system performance.
Third, anti interference ability
Interference can make the system automatically send alarm, the alarm has nothing to do with security tags. In the case of power failure or high ambient noise, may appear this kind of circumstance. Radio frequency system are particularly vulnerable to the interference of environment. Electromagnetic systems are also vulnerable to environmental disturbance, especially the interference of magnetic field. However, sound magnetic EAS system because of using computer control, and USES the unique resonance technology, so show strong resistance to environmental disturbance.
Fourth, the shielding
The shielding effect of metal can be about the detection of security label. This role include the use of metal objects, such as metal foil packing food, cigarettes, cosmetics, medicines, and metal products, such as battery, CD/DVD, hairdressing supplies and hardware tools. Even metal shopping cart and shopping basket will shield security system. Rf system are particularly vulnerable to the influence of shielding, large area of the metallic object will affect the electromagnetic system. Sound and magnetic EAS system because of adopting the low frequency magnetic coupling, generally only under the influence of all metal products, such as cooking utensils, etc., for the most part for other goods are very safe.
Fifth, strict security and smooth flow
Strong the EAS system need to consider the security needs and retail store traffic demands. Overly sensitive system affect shopping mood, lack of sensitivity of the system will reduce the profitability of the store.
Sixth, protection of the different types of goods
Retail goods generally can be divided into two categories. For soft commodities, such as clothing, footwear and textile goods, can be able to reuse of EAS hard tags to protect it. Another kind of hard goods, such as cosmetics, food, and shampoo, can be made of EAS disposable soft label to protect it.
Seventh, EAS soft label and hard label - the key is applicability
EAS soft label and hard label is an integral part of any EAS system, the performance of the whole security system also depends on the correct tags used appropriately. Especially is important to note that some labels easy be affected with damp be affected with damp and damage, some can't bend. In addition, some tags can be easily hidden in a box of goods, while others will affect the packaging of goods.
Eighth, EAS in addition to the punch and eraser
In the whole security link, EAS in addition to the punch and the reliability of the eraser and convenience is also an important factor. Senior EAS degaussing device adopts non-contact degaussing, to maximize the efficiency of cashier, speed up the checkout to traffic.
