Why does the dash cam not turn off after the engine is shut down?
2 Answers
The reason why the dash cam does not turn off after the engine is shut down is that the dash cam itself has a built-in battery, allowing it to continue working even after parking. The function of the dash cam: A dash cam is an instrument that records images, sounds, and other relevant information during vehicle travel. After installing a dash cam, it can record the entire driving process of the car, including video images and sounds, which can provide evidence for traffic accidents. Classification of dash cams: Dash cams are mainly divided into two categories: portable travel recorders and aftermarket integrated DVD travel recorders. Portable travel recorders are further divided into rearview mirror travel recorders and data travel recorders. These recorders are characterized by good concealment, easy installation, mobility and replaceability, low cost, and ease of use.
I had similar trouble right after modifying my car. The dash cam kept working and the light kept flashing after the engine was turned off. It was mainly because the parking monitoring function wasn't turned off. Some models continuously monitor the surroundings for anti-theft purposes. Or it could be a power wiring issue—if it's directly connected to the battery without a low-voltage protector, it should automatically shut off when the battery is low, but device malfunctions or incorrect settings might prevent it from recognizing the shutdown signal. The best solution is to check the dash cam's menu settings and turn off parking mode, then use a multimeter to test the cable connections to ensure there's no residual current when the engine is off. Don’t forget to check the user manual—some brands have dedicated apps for remote management, which is super convenient. If the issue persists, the internal module might be damaged, and you should take it to a repair shop for testing. Don’t delay, as it could drain the battery and affect your car’s usability the next day.
