What are the reasons for a dash cam screen distortion?
3 Answers
The reasons for a dash cam screen distortion include poor processing capability of the recorder itself, memory card failure, and hardware malfunction. Additionally, in most cases, screen distortion occurs because the light source frequency is not properly set, which needs to be adjusted according to the local power supply frequency. Generally, 50HZ should be selected in China, while 60HZ is chosen abroad. Below is a detailed analysis of the faults: Quality issues of the recorder: The most fundamental reason for dash cam screen distortion is the quality of the recorder itself. If the recorder's processing capability is too poor to keep up with the video processing speed, screen distortion will occur. Solution: Coordinate with the manufacturer to replace or repair the recorder. Memory card failure: Common quality issues like screen distortion, black screen, or lagging in dash cams are often due to the memory card's slow processing speed. Solution: Replace it with a high-speed memory card. Hardware malfunction: If neither of the above issues is present, the problem may be caused by hardware failure in the recorder. Solution: Check the reset button on the dash cam. If the problem persists after resetting, consider replacing it with a higher-version recorder.
I've encountered several instances of dashcam screen distortion while driving, with the most common cause being memory card issues. Problems like a full memory, damaged card, or improper formatting leading to read/write errors can result in mosaic-like images. Dust, fingerprints, or raindrops accumulating on the lens surface can also obstruct imaging, especially if not cleaned promptly during overcast or rainy weather, making the problem worse. Unstable power supply is another major factor—voltage fluctuations in the cigarette lighter or poor contact in the power cable can cause the dashcam to malfunction or even display distorted images. Outdated or faulty firmware can also lead to screen distortion, making regular software updates crucial. When temperatures are too high, the device's overheating protection may activate, causing the screen to distort, so remember to move it to a shaded area after parking. Simple routine maintenance can prevent these issues—clean the lens weekly, format the memory card monthly, check wire connections, and use high-quality branded cards. If screen distortion occurs, don't force it—first, park and restart the device. If that doesn't work, seek repairs. Small details can prevent big troubles.
As a daily driver, I think screen glitches in dash cams are usually no big deal. Most of the time, it's just the memory card being full or formatted incorrectly—simply reformat it or replace it with a new one. Dirty lenses are another common cause; oil or dust covering the lens can blur the image, so just wipe it clean with a soft cloth. Loose power cables or poor contact in the cigarette lighter plug can cause intermittent glitches—try reconnecting or switching to a higher-quality cable. Aging or physical damage to the dash cam might also lead to internal component issues, so handle it with care. In summer, parking in high temperatures can cause the device to overheat and affect the display, so try to avoid direct sunlight when parked. I recommend developing good habits: check the lens and memory card before each drive, and enable the auto-overwrite feature for old videos. If the problem persists, don't delay—take it to a professional shop to check the circuitry or replace parts. A small expense can ensure your safety.
