After 40 years of development, the anti-theft system has evolved from a single product with a single principle in the early days to a situation with a wide variety of different principles, adapting to the needs of different types of stores such as department stores, supermarkets, specialty stores, and libraries.
1. Subdivided from the protection form, it can be divided into vertical system, concealed system and channel system.
The detection device of the vertical system stands conspicuously at the entrance and exit of the shopping mall. In addition to the detection function, it also has an obvious deterrent effect.
The concealed system is to install the system concealed under the carpet or ceiling of the exit, which does not affect the overall environment of the store, and can also play a role of anti-theft protection, meeting the needs of the shop owner for both beauty and anti-theft.
The channel system is to integrate the EAS system with the checkout counter at the exit of the supermarket to form channel protection, which is an effective method to realize the anti-theft in the supermarket.
2. It can be distinguished by the detection signal method of its application, which can be roughly divided into radio system, electromagnetic wave system, microwave system, frequency division system, intelligent system and acousto-magnetic system.
