What Are the Reasons Why Some Dash Cams Fail to Record?

Reasons for dash cam recording failures include issues with the main control chip, power supply, memory card, and the device itself. Main Control Chip Issues: Poor quality of the chip. Power Supply Issues: Intermittent power supply due to poor contact. Memory Card Issues: Slow read/write speed of the memory card. Device Issues: Poor device quality leading to lagging. Recording Failures: If the dash cam fails to record, the causes should be checked one by one. Since the recorder may lag during recording, causing missed recordings, you can choose to restart the device or restore it to factory settings. If it's not a power supply issue, it could be a problem with the memory card's read/write speed. If the memory card has a slow read/write speed, there is a possibility of missing data. It is recommended to use a memory card with C10 read/write speed.
I also encountered a situation last week where the dash cam suddenly stopped recording. Later, I found out the main issue was with the memory card. Many recording failures occur because the memory card is full and doesn't automatically overwrite old files, or because the card's speed class is too low to keep up with high-definition recording speeds, resulting in dropped frames. Another common issue is poor power connection, such as a loose cigarette lighter socket or improperly connected voltage reducer cable causing power interruptions. Some cheap dash cams may also freeze and stop working when the car interior temperature gets too high in summer. It's recommended to first try formatting the memory card, then check if the power cable and connectors are loose. For safety, it's best to clean the memory card once a month.
As a frequent long-distance driver, I've found that dashcam failures are mostly due to setup issues. Many people don't realize the loop recording function isn't activated, causing the device to stop recording when memory is full. Another common issue is overly sensitive G-sensors that lock files upon minor bumps, preventing overwrites. Outdated firmware may also cause incompatibility with new-format memory cards. My experience suggests resetting dashcam settings with each memory card update, regularly checking recording status via mobile app, and reducing resolution to 1080P to minimize malfunction risks.
