EAS System Types
Jan 23, 2018

If the application of the detection signal to distinguish, can be divided into radio systems, electromagnetic systems, microwave systems, frequency systems, smart systems and acoustic systems.

Acoustic system

Tuning fork resonance only when the same oscillation frequency. Acusto Magnetic applies this physical principle to achieve virtually zero false positives. Acoustic magnetic tags fixed to the product resonate when they enter the detection area of the system, but only when the receiver receives After four consecutive resonance signals (once every 1/50 second), an alarm is issued.

Acoustic magnetic system features a high rate of anti-theft detection, almost zero false positives, good anti-interference, the protection of the export width of up to 3.5 meters, there are two kinds of anti-theft tag hardware and software, the mall can protect most types of goods , But also repeated demagnetization, even in POS cash register next to the system still work properly.

Acoustic and magnetic systems, including vertical systems, channel systems and concealed systems of different types, with more than 10 kinds of models to choose from, can be widely used in department stores, supermarkets, stores, audio-visual shops, grocery stores, pharmacies, can also be used Office buildings and other environments.

Radio system

Radio Frequency (RF) uses radio waves as the transmit and receive signals with a detection frequency range of seven. x ~ 8. x megahertz. The biggest advantage of radio system is the system cost is very low, easy to install. However, due to its anti-theft tag ring coil, so the system vulnerable to the interference of some items, such as cash registers and other electronic products, metal objects, etc., causing the system to false or unreported.

Radio system has soft and hard two kinds of labels, you can protect most of the items in the mall. The distance between the two supports can not be greater than 0 9 meters. It is usually used in a mall with only one entrance and exit. There are two vertical and channel radio system for the protection of department stores, clothing stores, supermarkets and so on.

Electromagnetic wave system

Electromagnetic system (Electromagnetic System) using electromagnetic waves as the detection signal.

Electromagnetic wave system has the smallest label, the label price is also cheap, repeated degaussing, but susceptible to magnetic or metallic substances resulting in false positives. Protection of the export width is generally about 0 9 meters. The system does not affect magnetic objects (such as audio tapes, video tapes, magnetic cards).

A new generation of channel electromagnetic wave system is a software-controlled electronic anti-theft system, using digital processing technology and degaussing system, cashier monitoring, CCTV monitoring system into one. The use of degaussing board, can degaussing repeatedly, the system cost is high. Electromagnetic wave system has vertical and channel two kinds. Application environment and more in the library, bookstore, sound stores, hotels, supermarkets and so on.

Microwave system

The microwave system uses microwave as a detection signal and is not easily disturbed by the surrounding environment. It can be flexibly and concealedly installed (such as under the carpet or suspended on the ceiling), and has the advantages of being suitable for interior decoration and appearance. However, due to the scope of Sheng should not be arranged in a certain region of goods, which for the land of gold, such as businesses, will limit the use of space, it is suitable for large department stores and stores larger music stores, boutiques use.

Frequency division system

SplitFrequency is an anti-theft system using high-tech crossover and ultra-low frequency radio signals. When an anti-theft tag enters the detection area, the tag receives the signal from the transmitting device and splits it into half and then sends half the information back to the receiver, only halfway through the receiver Alarm, can effectively avoid the interference of other radio waves.

Intelligent system

Intelligent system application of unique technology, is an internal control by the integrated circuit, battery-driven, set hard tags and alarm group as a whole system. When the tag was prized or with the goods were taken out of the mall, the system will automatically send an alarm.

The system enables the entire mall within the protection of goods, no error, the labels can be reused, without damaging the goods. Used to protect valuables, such as fashion, leather, fur clothing and so on.

Damage principle system

Anti-theft system destruction principle is a hard label or magnetic lock. The hard label contains ink, and when the thief attempts to remove the hard label, the hard label will jet ink, contaminate the product and the burglar's body. Magnetic lock is not easy to remove, forcibly removed will destroy the product, it is easy to use, has a very good deterrent effect, and low cost, used in clothing, glasses, jewelry, neckties, silk and other goods. Tags can be reused.
