All-in-one retail store electronic anti-theft alarm system (1)

In science and technology increasingly developed, all cost-effective today, retail store to human monitoring of traditional security methods are no longer appropriate, replaced by would be the application of high technology electronic goods anti-theft system.

Retail goods stolen phenomenon is a worldwide problem, according to foreign generally relevant statistics show that lost an only 9. 34 USD, $ 849 needs to be done to restore the loss of turnover. The loss of the goods has undoubtedly increased the burden on enterprises, to this end, loss prevention gradually as the leader of domestic enterprises. As early as the late 1960s, the United States appeared the first set of electronic goods anti-theft system EAS (Electronic Article Surveilance). Fundamentally changed in the past, everything for the customer to monitor security means. Introduction to commodity anti-theft monitoring to avoid consumer resistance, this anti-theft deterrent has to a large number of retailers by consensus. Currently, the world's large retail enterprises are using electronic anti-theft devices. EAS system 10 years ago began to Asian countries, Japan, Singapore, Korea and Hong Kong and Taiwan regions machine rate is increasing. China Enterprise accepts electronic anti-theft system is in the 1990s, in Beijing, Shanghai, Guangzhou, Shenzhen and other commercial developed cities began shopping centre EAS system installed.

Electronic anti-theft system after 40 years of development, from early in the development of a single principle of a single product to a wide variety of different principles now situation, adapt to department stores, supermarkets, stores, libraries, and other needs of the different types of stores.

1. from further broken down on the forms of protection, can be divided into vertical systems, concealed system and channel system.

Vertical system for detecting device prominently at the Mall entrance, with the exception of detection capabilities also has a significant deterrent effect.

Covert system was installed in the system hidden exports carpets or ceiling, does not affect the overall environment of the store, it can play a role of anti-theft protection, meet the shopkeeper is both beautiful and security needs.

Channel-type system in the supermarket outlet to EAS system with the cashier integrated, constitute the channel protection, is an effective way of supermarket burglary.

2. in its application of heartbeat to distinguish between, can be divided into radio systems, electromagnetic systems, microwave systems, frequency system, intelligent systems and magnetic system.

(1) sound magnetic system

Tuning fork only in the oscillation frequency is the same as the circumstances causing resonance.

Acousto-magnetic system (Acusto Magnetic) is the application of this principle, achieving almost physics with zero false positives, fixed merchandise sound magnetic system labels into the system of detection area, produces resonance, but only in the receiver receives fourth consecutive by resonance signal (every 1/50 seconds), it emits a beep.

Acoustic characteristics of the magnetic system is an intrusion detection rate is high, nearly zero false positives, immunity, protect's exports width up to 3. 5 m, there are two kinds of hardware and software, on the Mall anti-theft tag most types of goods can be protected, and can repeat degaussing, even in the POS cash drawer side system is still functioning.

Sound magnetic system including the vertical system, channel type system and covert system of different kinds, more than 10 kinds of models to choose from, can be widely used in department stores, supermarkets, stores, video stores, grocery stores, drug stores, also available in the Office building and the environment.

(2) radio system

Radio systems (Radio Frequency, RF) using radio waves as the emission of the signal received, the detection in the frequency range of the electromagnetic wave 8.8MHz 7.4-, center frequency is caused by the label 8.2MHz in 8.5MHz interference, thereby triggering the alert.

The biggest advantage of radio system is a system cost is very low, easy to install. However, due to its anti-theft tag for the loop type, so the system vulnerable to interference of some items, such as cash drawer, and other electronic products, metal, etc., caused by a system of false positive or not.

Radio system with soft and hard two labels, you can protect most of the items in the shopping centre.

Two bearing distance between generally cannot be greater than 0. 9 m, usually used in only one import and export of shopping malls. Radio system with vertical and channel-both for the protection of the Department stores, clothing stores, supermarkets, etc.
