Security life: electronic anti-theft system and function (1)

Electronic anti-theft system (EAS, Electronic Article Surveillance, hereinafter referred to as EAS) in small volume, value, easy stolen goods accompanied by an electronic anti-theft labels, in the shopping centre of the outlet with a check valve, when the thief get labeled merchandise through inspection door will immediately alert (like the airport entrance check-check), and good shopping after the cashier will enable labels fail, no alarm.

EAS system consists of soft labels system and hard tag system

1, soft label system: the detection antenna (transmitter and receiver), decoder and soft labels.

Use as long as the goods on soft label, you can achieve the purpose of the protection of the goods. When someone attempts to steal with label merchandise, goods after testing channel, detection antenna will detect the signal of labels on goods, simultaneously the alarm sound, timely alert security personnel, so as to achieve the security reasons. Normal purchase, a salesperson at checkout, anti-theft tag decoding, the customer can then "security". Soft tag system is mainly used for books, audio-visual products, cleaning products, cultural articles, such as shopping malls, soft label one-time use.

2. hard tag system: the detection antenna, detacher and various types of hard tags.

When you use the label will be hard goods (hand cannot take down), customer payment once a salesperson took down with detacher, hard tags with hard label merchandise through the detection antenna detection area, also raises an alert sound. Hard tag system is widely used for all types of clothing, shoes, shops and boutiques. Hard tag can be used over and over again.

Commodities electronic anti-theft alarm system overview

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. At present, 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.

Supermarket goods classification of electronic anti-theft alarm system

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, adapting to department stores, supermarkets, stores, libraries, and other needs of the different types of stores.

If the electronic anti-theft system from securing further broken down on the form, can be divided into vertical systems, concealed system and channel system.

Vertical system for detecting device prominently at the entrances of shopping centres, in addition to detection capabilities also has a significant deterrent effect.

Covert system was installed in the system hidden exports carpets or ceiling, and does not affect the overall environment in the store will also be able to play the 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.

If, in its application how to distinguish between heartbeats can be divided into radio systems, electromagnetic systems, microwave systems, frequency system, intelligent systems and magnetic system.

Acousto-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), after the 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 merchandise are 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, over more than 10 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.
