What is the drip of the driving recorder?

There are four reasons why the driving recorder drops: 1. The driving recorder battery is dead; 2. The data space in the driving recorder is insufficient; 3. The tachometer radar is detected by the driving recorder; 4. The car reversing radar sounds. Some driving recorders use batteries, so once the vehicle has no electricity, it will give an alarm to remind the owner that the battery needs to be replaced. If this happens, it is recommended to connect the driving recorder with the car cigarette lighter to avoid power failure. If insufficient memory leads to an alarm prompt, it is necessary to empty the memory space of the driving recorder in time. In addition, some driving recorders can detect the speed radar and give an alarm to remind drivers to pay attention to the speed and slow down. Million car purchase subsidy
