What are the reasons for the dash cam not working?

[DelGabriela]

The reason the dash cam is not working is due to a dead battery. Below is an introduction to the functions of a dash cam and considerations for purchasing one: Functions of a Dash Cam: A dash cam is a device that records images, sounds, and other relevant information during vehicle travel. After installation, it can record the entire driving process in video and audio, providing evidence in case of traffic accidents. Considerations for Purchasing a Dash Cam: A dash cam should have good camera clarity and night recording capabilities. High definition is determined by the main control chip of the dash cam, so owners should pay attention to the image processing solution used by the main control chip. Additionally, the dash cam should have sufficient storage space to enable long-term effective recording.

I've been driving for over a decade and encountered dash cam malfunctions several times. The main causes are usually loose cigarette lighter plugs or blown fuses in the power system - these are the most common yet easily overlooked issues. Secondly, storage card overflow or dirty card slots causing read failures can often be resolved by simply removing and reinserting the card followed by formatting. Hardware problems like damaged cameras or internal circuit failures are less common, but the device may automatically shut down for protection when overheating, especially noticeable in summer. Incorrect settings might also trigger malfunctions, such as forgetting to enable recording mode or setting the screen-off time too short. I recommend regularly cleaning device ports, backing up data, using a multimeter to check wiring integrity, and seeking professional repair when issues arise to ensure driving safety.

As an ordinary driver, I've found that when a dashcam malfunctions, it's often due to minor details. The most common issue is a loose power cable connection – a gentle tug on the plug can test this. Poor memory card compatibility can also cause problems; try switching to a high-speed card. Sometimes, forgetting to turn on the power switch or setting the resolution too high in the settings can lead to crashes, which can usually be fixed by restarting the device. Environmental factors like cold weather preventing the device from starting can be resolved by warming up the car before checking. It's advisable to keep a spare power adapter in the car and check if the indicator light is on before driving – simple maintenance can prevent major issues.

From a technical perspective, dashcam malfunctions are commonly caused by unstable power supply or signal interference. Insufficient cigarette lighter output or blown fuses should be prioritized for troubleshooting. Damaged or incompatible memory card formats can interrupt recording, which may be resolved by reformatting or firmware updates. Internal components such as faulty sensors or aging batteries also affect performance. It's recommended to test card read/write functions and replace hardware promptly to prevent unexpected failures.
