Definition of Electronic anti-theft device
Use modern electronic high-tech products to prevent all kinds of tangible property and intangible property from being maliciously taken, stolen, scraped, robbed and stolen by others. Mechanical anti-theft devices are devices that prevent car theft, but they do not prevent others from entering the cab, inside the car, opening the luggage compartment, hood, or starting the engine. At present, the car anti-theft device has been developed from the initial mechanical control to the car anti-theft system of key control – electronic password – remote call for help – information alarm, from the previous simple mechanical key anti-theft technology to electronic anti-theft and biometric electronic anti-theft.
Types of Electronic Security Systems
1. Key control type. By opening or locking the door lock with the key, the anti-theft system is set or released at the same time.
2. Remote control. The anti-theft system can remotely control the door lock to open or lock release.
3. Alarm type. When the anti-theft system encounters the car being stolen, it only alarms but does not prevent the car from moving.
4. With anti-theft alarm and anti-theft system to prevent vehicle movement. When there is a stolen car, in addition to the audio signal alarm, it can also cut off the car’s starting circuit, ignition circuit or oil circuit, etc., to prevent the car from moving.
5. Electronic tracking anti-theft system. The system is divided into satellite positioning and tracking system (referred to as GPS): and the use of walkie-talkies through the central control center positioning monitoring system.
The composition of commonly used anti-theft devices
The general anti-theft device consists of fuel cut-off device, steering lock, various electronic alarms, ignition system shut-off device, mechanical anti-theft locks of various external methods, and electronically controlled anti-theft systems.
Car anti-theft device installation precautions
Many cars are now pre-installed with a car computer anti-theft system before leaving the factory. When the data of the key chip matches the data stored in the on-board computer, the computer will notify the relevant system to start working and allow the engine to start. Cars with their own on-board computer anti-theft system do not need to install electronic anti-theft devices. If installed, it is easy to conflict with the anti-theft system installed in the original car; if you must install an additional electronic anti-theft device, please pay attention to separating it from the ignition system, otherwise it will cause the engine to fail to start and other failures. When there is a fault, you need to go to a professional car lock shop to use a professional decoder to clear the fault code.
