Background technique

According to statistics, there are about 50,000 car thefts and 210,000 locomotive thefts in Taiwan each year, with an average of 30 autos and motorcycles stolen every hour. In addition to causing loss of property of the owner, vehicle theft often becomes a tool of crime and causes a blind spot for public security.

At present, there are various products (such as locks, anti-theft devices, etc.) and methods (such as body and parts branding) for anti-theft of vehicles on the market. These products and methods are all to provide an extra layer of protection against vehicle theft . Although there are many types of products and methods for vehicle anti-theft on the market, there is always a lack of an anti-theft device with complete functions to provide a comprehensive and complete protection for vehicle anti-theft.

In addition, with the increase of the anti-theft function, its price has also risen with the tide, making many consumers discouraged. Among them, the anti-theft device that reports the occurrence of the vehicle through the control center needs manpower to operate, which increases the burden of expenses.
