Common car anti-theft devices

"There are always people who better than you". The failure of the anti-theft device has caused many car owners to use various anti-theft tricks. According to Mr. Ye, the owner of the car, he added an oil circuit and a circuit dark circuit switch in a corner of his car. After a thief broke the window and entered the car, he did not start the car for nearly 20 minutes. Others took small parts such as ignitors with them when leaving the car.

Mr. Chen, a senior technician at a 4S shop, said that if it is only hoped that the anti-theft device will block all the thieves, it is definitely unrealistic to have more knowledge about car anti-theft and a little more awareness. According to technician Chen, if there is a problem with the quality of the automobile anti-theft device, or if it is blindly modified and the method of use is incorrect, the anti-theft effect will not be achieved. Therefore, when purchasing an anti-theft device, we must first pay attention to whether the anti-theft product has been tested by the Ministry of Public Security and whether the product's origin is indicated; vehicles that have installed an anti-theft system for vehicles do not need to install anti-theft products; In the end, if the conditions permit, you can consider to insure the vehicle.
