With the development of science and technology and the quest for efficiency, today's traditional theft prevention methods for retail stores using human power to monitor shopping malls are no longer appropriate. Instead, high-tech electronic goods theft protection systems will be used instead. The theft of retail merchandise is a worldwide problem. According to statistics from abroad, the loss of a US$9.34 worth of goods requires US$849 in turnover to recover losses. The loss of commodities undoubtedly aggravated the burden on the company. For this reason, loss prevention has gradually become the focus of domestic business leaders.
As early as the late 1960s, the United States had the first
Electronic Article Surveillance (EAS) electronic article surveillance (Electronic Article Surveillance). Fundamentally changed all previous anti-theft measures aimed at customer monitoring. The implementation of anti-theft surveillance on commodities prevents consumer resistance and this anti-theft deterrence has been agreed by many retailers. At present, most large-scale retail companies in the world use electronic anti-theft devices. The installation rate of EAS systems that entered the Asian countries 10 years ago, Japan, Singapore, South Korea, and Hong Kong and Taiwan has been increasing year by year. After Chinese enterprises accepted electronic anti-theft systems in the 1990s, they began to install EAS systems in shopping malls in Beijing, Shanghai, Guangzhou, and Shenzhen.
After 40 years of development, the electronic anti-theft system has evolved from a single single-principle single product to a wide variety of different principles and adapts to the needs of different types of stores such as department stores, supermarkets, specialty stores, and libraries.
1. Subdividing from the form of protection can be divided into vertical system, concealed system and channel system.
The detection system of the vertical system stands proudly at the entrance and exit of the shopping mall and has a clear deterrent effect in addition to the detection function.
The concealed system conceals the system under the carpet under the exit or at the ceiling. It does not affect the overall environment of the store and can also function as a theft protection to meet the needs of the owner who is both beautiful and anti-theft.
The channel system integrates the
Eas System with the cash register at the exit of the supermarket to form a channel-type protection, which is an effective method to achieve theft prevention in the supermarket.
2. It can be divided into radio system, electromagnetic wave system, microwave system, frequency division system, intelligent system and acousto-magnetic system.
(1) Acoustic-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. When a sound-magnetic system tag fixed on a commodity enters the detection area of the system, it will generate resonance but it will only be received by the receiver. The alarm is issued only after four consecutive resonance signals (once every 1/50th of a second).
The characteristics of the acousto-magnetic system are high anti-theft detection rate, almost zero false alarms, good anti-interference, and the protection of the export width of up to 3.5 meters, there are two anti-theft labels soft and hard, for most types of shopping malls can be protected, and Demagnetization can be repeated, even if the system is still working at the POS cash register.
The acousto-magnetic system includes vertical system, channel system and concealed system different types. There are more than 10 models to choose from, which can be widely used in department stores, supermarkets, specialty stores, audio-visual shops, grocery stores, pharmacies, etc. Office buildings and other environments.
(2) Radio System (Radio Frequency, RF) uses radio waves as signals for transmission and reception, detects electromagnetic waves in the frequency range of 7.4-8.8 MHz, and has a center frequency of 8.2 MHz. Call the police. 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 items, such as electronic products such as cash registers and metal objects, which cause 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, for the protection of department stores, clothing stores, and supermarkets.
(3) Electromagnetic wave system Electromagnetic wave system (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 protected exit width is generally about 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 microwave as a detection signal and is not easily disturbed by the surrounding environment. It can be installed in a flexible and concealed manner (such as hidden under a carpet or suspended from a ceiling), and is suitable for interior decoration and aesthetics. The advantages. However, due to the large scale 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 division system Frequency division system (SplitFrequency) is a high-tech frequency division technology and ultra-low frequency radio wave signal anti-theft system. 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 kinds of vertical and concealed products, which is an ideal anti-theft system for clothing and apparel.
(6) Wisdom system The unique technology of the smart system application is an internal integrated circuit control, battery drive, hard tag and alarm group. When the tag is picked up or taken out of the store along with the product, the system automatically sends 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 The anti-theft system of the system destruction principle is a hard tag or magnetic lock. The ink is contained in a hard tag. When the thief attempts to remove the hard tag, the hard tag will eject ink, contaminating the body of the goods and the burglar. Magnetic lock is very difficult to dismantle, forcibly remove it will destroy the goods, it is easy to use, has a good deterrent effect, and the cost is very low, applied to clothing, glasses, jewelry, ties, silk and other goods, the label can be reused.
In addition to electronic article surveillance systems, closed-circuit television monitoring systems (Closed-Circuir Television, CCTV) are closely related to theft prevention in shopping malls. Closed-circuit television monitoring systems can monitor what is happening in shopping malls and discover suspicious events and act as deterrents to deter use. Compared with the electronic anti-theft system, the advantage is that it can not only effectively monitor the situation in the mall, and can use the video tape to record the incident or theft process, as the basis for the follow-up investigation and evidence collection. Conditional shopping malls can combine electronic anti-theft systems with CCTV. This can effectively prevent internal and external thief crimes, increase theft prevention effect, and reduce the loss of retail goods.
