The supermarket burglar alarm system is generally divided into three major technologies. The following editor will give you a brief introduction to these three technologies.
1. Electronic product anti-theft system
The electronic commodity anti-theft system is referred to as the EAS system, which basically consists of three parts: the electronic induction card (or label), the decoder (or puller) and the detector (detection door). The detector is installed at the general entrance and exit of the shopping mall or the exit of the specially set customer passage.

In recent years, with the development of multimedia technology and computer image file processing technology, the video surveillance system has made great progress in realizing video alarm, automatic tracking, real-time processing, etc. has an important position.
