High-tech electronic goods anti-theft system introduction and application of

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.

(3) the electromagnetic systems

Electromagnetic wave systems (Electromagnetic System) using electromagnetic waves as the heartbeat.

Electromagnetic wave system label smallest, label the price is cheap, can duplicate the degauss, but vulnerable to magnetic or metallic substances in which produce false positives. Protection of width is generally 0. 9 meters. The system will not be on magnetic materials (such as audio and video tapes, magnetic card). The new generation of channel-type electromagnetic systems is a software-controlled electronic anti-theft system, using a digital processing techniques and degaussing systems, cash register monitoring, closed circuit television monitoring system integration. Use the quick degaussing plate, can duplicate the degauss, system cost. Electromagnetic systems have vertical and channel two. Application environment more in libraries, bookstores, music stores, hotels, supermarkets, etc.

(4) microwave systems

Microwave systems (Microwave System) using microwave as heartbeat, insensitive to ambient interference, its flexibility to covert installation (such as hidden under the carpet or hanging on the ceiling), suitable for shop decorative and attractive benefits.

But because of the large range of the receptacle shall, in a certain region cannot arrange merchandise, this gold to the inch, the businessmen will limit the use of space, therefore suitable for large department stores and store larger music shops, boutiques.

(5) frequency system

Frequency-division system (SplitFrequency) is made of high-tech low frequency radio frequency technology and signal security system.

When a detection zone anti-theft tag entry, label receivedReceive the Launcher passes signal, and put it into half, and then has been divided into half of the information transmitted to the receiver, the receiver has received only half a signal when a beep, can effectively avoid interference from other radio waves. The system label light, small, cheap, stable performance, high rate of detection, anti-jammings well, does not cause false positives. Products are vertical and subtle type two, is a fashion shop more ideal anti-theft system.

(6) the intelligent system

Intelligent systems application unique technology, is an internally by IC control, battery-driven, set hard tags and alarm group as one of the system.

When the label was prized or with the goods being brought out shopping centre, the system will automatically alarm. The system can make the entire Mall-wide goods are protected, accurate report, tags can be reused, without damage of goods. Used to protect valuables, such as fashion, leather, fur coat, etc.

(7) the principle of system failure

Undermine the principle of the anti-theft system is a hard tags or magnetic locks.

Hard tag contains ink, when the thief trying to dismantle this hard tag, hard tags will emit ink, contaminated goods and thieves. Magnetic lock very easily dismantled, forcibly removed will destroy the goods, it is easy to use, has a very good deterrent effect, and the cost is very low, in clothing, glasses, jewelry, ties, silks and other goods, labels can be reused.

In addition to electronic goods anti-theft system, closely linked with the Mall Security are closed circuit television monitoring system (Closed-Circuir Television, CCTV).

Closed circuit television monitoring system can monitor Mall in situation and suspicious incidents, deter deterrent. Compared with electronic anti-theft system, their advantage is that it not only can effectively monitor the Mall, and take advantage of the video of the event or theft process documented as a basis for future tracing of forensics. Conditional shopping can make electronic anti-theft system in conjunction with CCTV, the more effective in the prevention of crime within and outside the thief, increase security, reduce retail merchandise effect.
