At present, there are two main types of GPS locators on the market based on their power supply: one is equipped with a built-in battery that does not require external power supply, and the other is equipped with a backup battery that mainly relies on vehicle power supply.

　　The advantage of having a built-in battery is self-evident, as it does not require wiring and can be placed in any corner of the vehicle, and can be used for personal or valuable item positioning. The disadvantage is that there is no continuous power supply, so after standby time, it needs to be recharged for continued use. Moreover, due to the need for charging, it is not convenient to place it in complex areas inside the vehicle, making each disassembly and assembly very time-consuming and laborious.

　　The wiring type needs to be connected to the vehicle's power supply line, so car thieves can search for the GPS locator along the power supply line and remove it. If other functions are installed, the installation position of the locator can be basically determined. Of course, there is no need to worry about GPS locators not functioning properly to prevent theft. If the vibration alarm function is installed, if the thief does not start the vehicle through the car key within a certain period of time after opening the car door or suddenly loses power, the GPS locator will send a vibration alarm to the owner through SMS and phone calls, achieving real-time anti-theft effect. Because it is through text messages and phone calls, even if the car owner is thousands of miles away, they can immediately learn about someone stealing a car and take relevant measures such as reporting to the police or remotely cutting off fuel and power to prevent car theft.
