What to Do If the Dash Cam Frequently Restarts?
3 Answers
Format the memory card and then restore factory settings. Below is relevant information about dash cams: 1. Introduction: A dash cam is a device that records images, sounds, and other related information during vehicle travel. After installing a dash cam, it can record the entire driving process's video images and sounds, providing evidence for traffic accidents. For those who enjoy road trips, it can also be used to document the process of overcoming challenges. 2. Possible Causes: (1) The SD card may be faulty—try formatting it. (2) The dash cam's firmware may need updating—refer to the manual. (3) The battery may be faulty—try draining it completely and reconnecting. (4) There may be an issue with the wiring—try replacing the power cable.
During my last road trip, the dash cam kept restarting and almost made me miss the scenery. After struggling for a while, I realized it was a car charger issue. Poor contact in the cigarette lighter socket causes unstable power supply—switching to a dedicated car charger with spring contacts solved it immediately. Also, pay attention to the memory card; insufficient write speed can cause interrupted recording and trigger restarts. It's best to choose Class10 or higher. If restarts happen more frequently in hot summer, it's likely the device overheating triggering the protection mechanism—applying a heat-insulating film on the windshield can help. Oh, and firmware bugs can also cause erratic behavior, so remember to regularly check the official website for updates. Last time I updated the firmware, even the error codes disappeared.
Based on my 20 years of auto repair experience, dashcam restarts are 80% likely due to power supply issues. Aging car batteries with unstable output voltage are the main culprit, especially during winter startups when voltage drops drastically. The wiring check is straightforward: first replace with a three-core shielded cable to eliminate interference, then test if the cigarette lighter voltage is below 5V. Don't overlook the device side either - a swollen lithium battery can cause intermittent power cuts; if you pry open the back cover and see wrinkled battery skin, it's time for replacement. Storage issues are also easy to diagnose: memory cards with exhausted flash memory lifespan will repeatedly trigger system resets, and any card with read/write speeds below 10MB/s should be discarded immediately.
