In many cases, for safety reasons, car companies need to install a GPS locator on their cars to prevent some criminals from using mortgages to purchase cars for car fraud and insurance fraud, and to avoid the situation of "people without a trace and cars without a trace". So what GPS locator should be installed on a mortgaged car?

　　Generally speaking, a wired device and multiple wireless devices are installed on the mortgaged car. The wired device is used for monitoring the daily behavior of the car, with a real-time upload frequency of 30s/time, to know the status and location of the vehicle at any time. Wireless devices are equipped with concealed alarm clock positioning mode and remote tracking mode in emergency situations, which can effectively prevent GPS locators from being blocked and disassembled. The combination of light and dark provides higher security and is a widely used and mature solution. Using this scheme can achieve:

　　1. Accurate positioning, always keeping track of the vehicle's location

　　Synchronize the reception of signals from Chinese Beidou and American GPS satellites, as well as base station signals, and combine multiple signals to quickly and accurately locate the vehicle's position, leaving no signal blind spots untouched. In addition, its strong anti-interference, waterproof, and dustproof capabilities are sufficient to cope with multiple environmental changes and ensure smooth signal reception.

　　2. Vehicle behavior monitoring, pre judging vehicle risks

　　In the context of big data, sending command short messages to GPS locator devices through mobile phones enables remote viewing of vehicle location, cutting off fuel and electricity, setting device positioning online frequency, and other functions, thereby achieving real-time positioning with increasing accuracy and an error range of less than 10m. Through the intelligent monitoring of the platform and GPS locator, based on the vehicle trajectory and commonly used parking addresses, combined with the provided information, the authenticity and validity of the information can be identified.

　　3. Multiple alarm functions, timely control of vehicle hazards

　　The car GPS locator is one of the essential risk control methods in the automotive finance industry. It can achieve comprehensive alarm monitoring through multiple alarm functions such as vibration, power outage, displacement, light sensing anti disassembly, interception, etc. It can also be combined with remote fuel and power outage control to start the vehicle, provide timely feedback and control of vehicle danger, and minimize risks.
