There are the following types of car anti-theft devices

1. Mechanical anti-theft device, such as steering wheel lock, padlock lock, etc. (Available at roadside shops, around 100-200 yuan)

2. Electronic anti-theft alarm (also known as microcomputer car anti-theft device) is an alarm that whistles when the car body touches or vibrates (available at roadside shops, about 100-200 yuan). Because the use frequency of this type of electronic anti-theft alarm is generally limited to the amateur band of 300 ~ 350MHz, and there are many sources of electronic wave interference in this band, radio waves, lightning, industrial welding, etc. and wind and grass will interfere with it and generate false alarms. Currently tending to be eliminated.

3. Network anti-theft system, this type of car anti-theft system is divided into satellite positioning tracking system (referred to as GPS) and the use of vehicle-mounted platform (interphone) through the central control center positioning monitoring system. This is a high-level anti-theft mode. Public Security likes you to install this type of anti-theft device and can charge a service fee.

4. Digital anti-theft device PATS microcrystalline identification password anti-theft system: (Fox standard anti-theft configuration) unique electronic passwords up to more than 50 billion types, when the password transmitter is installed with a car key inserted, the receiving module in the key hole Pass the password to the control module for interpretation. If it matches, the car engine can be started. The system does not use battery wires, and it can be ignited by wiring. If the control module does not lift the ban, the engine will not start. The digital anti-theft key integrates a miniaturized radio transmitter with a car key, and is equipped with a receiving reader in the hidden place of the steering wheel. When this car key is inserted into the ignition switch, a radio signal with 20 digital codes is emitted. After the reader receives it and confirms that it is correct, the ignition switch will start the vehicle. If the digital code does not match or no signal is sent, the vehicle will Unable to start ignition.
