How to Solve the Reflection Problem in Dash Cams?
3 Answers
To address the reflection issue in dash cams, you can place a black cloth on the windshield to absorb light or adjust the angle of the dash cam. The reflection problem primarily occurs due to the principle of mirror reflection, where objects inside the car reflect off the windshield and onto the dash cam's lens. A dash cam is an instrument that records images, sounds, and related information during vehicle operation. After installation, it can capture the entire driving process in video and audio, providing evidence in case of traffic accidents. Dash cams are categorized into portable dash cams and aftermarket in-dash DVD dash cams.
The reflection in the dashcam is usually caused by the glass, especially the reflection of the interior parts or strong light from the windshield. The solution is simple: First, try adjusting the installation position of the dashcam, move it further away from the glass, or place it right below the rearview mirror to avoid direct light sources. Second, add an anti-glare hood or shading kit—there are many affordable accessories available online that can effectively block external light. Third, cleaning the glass is crucial—use a clean, soft cloth to remove dust and scratches to reduce reflections. I encountered a similar issue before—I initially thought the dashcam was broken, but later realized it was just poorly positioned. After adjusting it, the reflection was mostly gone. If these DIY methods don’t work, you can consider applying an automotive anti-reflection film or purchasing a dashcam model with a built-in polarizing lens. These options can enhance video clarity and ensure safer driving.
In my driving experience, dashcam reflection issues are quite common, especially on sunny days when blurry shadows appear on the screen and affect video quality. I've dealt with this multiple times: the first step is to reposition the device away from reflective surfaces like the dashboard or instrument panel; try moving it lower or closer to the edge of the window. Secondly, adding a simple sunshade helps—I once made a cardboard hood for my dashcam to block light. Additionally, ensure the windshield is thoroughly cleaned with automotive cleaner to remove grease stains. These low-cost methods deliver noticeable results, restoring clear footage and preventing driving distractions. Of course, if reflections persist, it might indicate subpar dashcam quality—consider upgrading to a model with anti-glare features for more reliable performance and greater peace of mind during daily drives.
