Supermarket security door principle seven anti-theft principle makes your anti-theft system more secure

With the development of science and technology and the quest for efficiency, today's traditional theft prevention methods for retail stores with human monitoring of shopping malls are no longer appropriate. The application of supermarket theft prevention systems is very common. So, what is the principle of supermarket security door , the following small series to introduce you to the principle of supermarket security system.

Supermarket security door principle

Divided by the detection signal method applied by the supermarket anti-theft system, it can be roughly divided into a radio system, an electromagnetic wave system, a microwave system, a frequency division system, a smart system, and an acousto-magnetic system.

1. Acoustic and Magnetic System

The tuning fork only causes resonance if the oscillation frequency is the same. Acusto Magnetic (Acusto Magnetic) is the application of this physical principle, to achieve almost zero false alarm operation, the sound and magnetic system tag fixed on the goods will enter the system's detection area, it will generate resonance, but only at the receiver to receive The alarm is issued only after four consecutive resonance signals (once every 1/50th of a second).

Acoustic and magnetic system features high anti-theft detection rate, almost zero false positives, good anti-interference, and the protection of the export width of up to 3.5 meters, there are two hard and soft anti-theft tags, most types of goods can be protected on the mall , And can repeat degaussing, even at the POS cash register next to the system can still work.

The acousto-magnetic system includes vertical system, channel system and concealed system. There are more than 10 models to choose from, which can be widely used in department stores, supermarkets, specialty stores, audio and video stores, grocery stores, pharmacies, etc. Office buildings and other environments.

2 , radio system

The radio frequency (RF) uses radio waves as the signal for transmission and reception, and the detection frequency range is 7. x~8. X megahertz. The biggest advantage of the radio system is the very low system cost and easy installation. However, since its anti-theft tag is a toroidal coil type, the system is susceptible to interference from some articles, such as cash registers and other electronic products, metal objects, etc., causing false alarms or non-reports of the system.

The radio system has two labels, soft and hard, that can protect most items in the mall. The distance between two bearings can not be more than 0 9 meters, usually used in a shopping mall with only one import and export. The radio system has two types, vertical and channel, and is used to protect department stores, clothing stores, and supermarkets.

3 , electromagnetic wave system

The Electromagnetic System uses electromagnetic waves as detection signals.

The electromagnetic wave system has the smallest label, the label price is also low, and the demagnetization can be repeated, but it is susceptible to the occurrence of false positives due to the influence of magnetic or metallic substances. The width of the protected outlet is generally around 0-9 meters. The system will not affect magnetic objects (such as audio tapes, video tapes, magnetic cards).

The new generation of channel-type electromagnetic wave system is a software-controlled electronic anti-theft system, using digital processing technology and degaussing system, cashier monitoring, closed-circuit television monitoring system. The use of fast degaussing plates enables repeated demagnetization and high system costs. There are two types of electromagnetic wave systems: vertical and channel. The application environment is mostly in libraries, bookstores, sound shops, hotels, supermarkets, etc.

4 、Microwave system

The Microwave System uses microwaves as a detection signal, which is not easily disturbed by the surrounding environment. It can be installed in a concealed manner (such as concealed under a carpet or suspended from a ceiling), which is suitable for interior decoration and aesthetics. However, due to the large scope of Shengying, it is impossible to arrange products in a certain area. This would limit the use of space for merchants with a high price of land. Therefore, it is suitable for use in large department stores and large music stores and fashion stores.

5 , frequency dividing system

Split Frequency is an anti-theft system using high-frequency crossover technology and ultra-low frequency radio wave signals. When a security tag enters the detection area, the tag receives the signal transmitted by the transmitting device, divides it into half, and then transmits the divided information to the receiver. Only when the receiver receives half the signal Sending an alarm can effectively avoid interference from other radio waves.

The system is light in label, small in size, cheap in price, stable in performance, high in detection rate, good in anti-interference, and less likely to cause false alarms. There are two types of vertical and concealed products. It is an ideal anti-theft system for clothing and apparel shops.

6 , smart system

The unique technology of the smart system application is a system that integrates the integrated circuit control, battery drive, and hard tags and alarms. When the tag is picked up or taken out of the store along with the product, the system will automatically issue an alarm.

The system enables the entire store to be protected, with no errors, and the labels can be reused without damaging the merchandise. It is used to protect valuables, such as fashion, leather, and clothing.

7. Destruction principle system

The anti-theft system of the principle of destruction is a hard tag or magnetic lock. In the hard tag, ink is contained. When the thief tries to remove the hard tag, the hard tag will eject ink and contaminate the goods and the body of the burglar. Magnetic lock is very difficult to dismantle, forcibly dismantling will destroy the goods, it is easy to use, has a good deterrent effect, and the cost is very low, used in clothing, glasses, jewelry, ties, silk and other goods. Tags can be reused.

What is the principle of supermarket anti-theft system, the above is the introduction of the principle of supermarket anti-theft system. Installing a supermarket anti-theft system can reduce the loss of goods, reduce employees, assist in management, and increase profits. For more information on anti-theft, please continue to pay attention to information on this site.
