What are the reasons for a dash cam constantly rebooting?

The reasons for a dash cam constantly rebooting are: 1. Power supply failure; 2. Wiring issues; 3. Memory card problems; 4. Issues with the dash cam itself. The solutions for a dash cam constantly rebooting are: 1. Unplug the dash cam's power supply and test with another device to check for power supply failure; 2. Reconnect the power cable; 3. Format the memory card or insert a piece of paper behind the memory card; 4. Reset the dash cam to factory settings. The functions of a dash cam are: 1. Protecting the car owner's legal rights and preventing fraud; 2. Determining liability in accidents; 3. Serving as a parking monitor; 4. Capturing scenic views.
When the dash cam keeps restarting, I suspect the power supply is the prime suspect; a loose cigarette lighter plug or a faulty charger causing unstable power can trigger the dash cam's restart protection mechanism. Memory card issues are also common; if the card is full, formatted incorrectly, or not fast enough, the dash cam fails to write data and enters a restart loop. Hardware failures, such as an aging built-in battery that can't start after parking power-off, or sensors falsely triggering a restart, are possible causes. Firmware problems, like unupdated software bugs or corrupted settings, may require a reset to resolve. Significant vehicle voltage fluctuations when turning on headlights or air conditioning can also cause restarts, and overheating in summer can trigger self-protection shutdowns and restarts. To troubleshoot, check the power connection first, format the memory card or replace it with a high-speed one, and update the dash cam's firmware version. Delayed action may result in missing critical recordings, so regular maintenance is essential for safety.
I've encountered situations where the dashcam keeps restarting, mostly due to power supply issues; poor contact in the cigarette lighter socket or a damaged car charger causing repeated power disconnections. The memory card is also a common culprit; when the card is full or damaged after prolonged use, write failures occur, prompting the dashcam to retry and get stuck in a reboot loop. On the hardware side, an aging dashcam with a failing battery may not restart after power loss, or overheating on hot days can trigger automatic reboots due to protection mechanisms. Voltage instability—such as during engine startup or when multiple electrical devices are in use—can also cause restarts. Troubleshooting steps include: securing the plug to prevent wobbling, clearing the card's contents or switching to a branded high-speed card, and placing the dashcam in a well-ventilated area to avoid overheating. Don’t underestimate this issue—if the recording stops during a reboot, you might lose critical evidence in case of an accident. Regular checks and maintenance are recommended to minimize malfunctions.
