Description

A novel anti-theft system and its control method

technical field

The invention relates to an anti-theft system and a control method thereof, in particular to an anti-theft system and a control method thereof which perform different alarm and reminding modes according to different distances.

Background technique

With the continuous progress of society and the development of science and technology, people's awareness of their own property protection has been greatly improved. Some network operators have proposed corresponding countermeasures against the problem of anti-theft, such as adding fingerprints, voice recognition, video surveillance, GPS, Bluetooth , radio wave monitoring, etc. However, looking at these anti-theft functions, they can only passively prevent others from taking illegal means, without giving others time to consider or any alarm prompts, which are relatively negative in preventing financial loss. Some network operators have proposed corresponding countermeasures against the anti-theft problem, such as adding fingerprint, voice recognition, camera, GPS, Bluetooth, and wireless functions. But looking at these anti-theft functions, they can only passively prevent others from taking illegal means, which is negative and has no positive significance for preventing financial loss. At the same time, due to environmental interference, it often causes misoperation. Missing the opportunity to alert the police would do more damage.
