What kind of good anti-theft access control in supermarket
For supermarket anti-theft access control, there are currently two types of supermarket anti-theft access control systems on the market, namely radio-frequency access control systems and acoustic-magnetic anti-theft access control systems.
What kind of supermarket anti-theft access control is good, each system has a targeted difference, and its functions are different.
线电射频门禁系统 ，采用的是无线电波作为发射接收的信号，检测频率范围为7． For the radio frequency access control system , radio waves are used as the transmitted and received signals, and the detection frequency range is 7. x ～ 8. x MHz. The transmitted signal is a radio signal, which is the same signal as a mobile phone and a radio, but with different frequencies. The biggest advantage of the radio system is that the system cost is very low and the installation is convenient. However, because the matching anti-theft tag is a toroidal coil type, the radio frequency access control system is susceptible to interference by some items, such as cash registers, electronics, metal objects, etc. These have a greater impact on the radio frequency access control system.
The radio frequency access control system should be used with both soft and hard tags to protect most items in the mall. The distance between the two supports is generally not greater than 1.2 meters, and is usually used in shopping malls with only one entrance or exit. There are two types of radio systems, vertical and aisle, used to protect department stores, clothing stores, supermarkets, etc.
For the acoustic magnetic anti-theft access control system, the function is that the tuning fork only causes resonance under the same oscillation frequency. Acoustomagnetic anti-theft access control system uses this physical principle to achieve almost zero false alarm operation. When an acoustic magnetic system tag fixed on a product enters the detection area of the system, resonance will occur, but only when the receiver receives continuous The alarm is issued after four resonance signals (every 1 / 50th of a second).
Acoustic and magnetic anti-theft access control system features high anti-theft detection rate, almost zero false positives, good anti-interference, and a protected exit width of up to 3.5 meters. There are two types of anti-theft labels, hard and soft. It can be protected and can be demagnetized repeatedly. The system can work normally even near the POS register.
Acoustomagnetic systems include different types of vertical systems, channel systems, and concealed systems.There are more than 10 models to choose from, which can be widely used in department stores, supermarkets, specialty stores, audiovisual stores, grocery stores, drug stores, and can also be used in Office buildings and other environments.
It is recommended to use radio frequency systems for supermarket anti-theft access control, because many goods in the supermarket require anti-theft soft labels, such as washing powder, shower gel, shampoo, etc., all use anti-theft soft labels, and radio frequency access control systems are the most popular. Good supporting anti-theft equipment.
