I've been driving for over a decade, and the pixel quality of dash cams is quite a practical matter. The mainstream market now mostly offers 1080p full HD, with a resolution of about 2 megapixels, which is sufficient for daily driving to clearly see license plates and road condition details. If you frequently drive long distances or at night, I recommend opting for a higher pixel count, such as 1440p or 4K, with 3-4 megapixels, to avoid blurry images in low light. However, too high a pixel count also has drawbacks—video files are larger, requiring at least a 64GB memory card for adequate storage; otherwise, the card fills up quickly and may miss recording critical moments. From my experience, don't just chase pixel numbers—check the lens's wide-angle and night vision capabilities, and choose based on your driving habits. Safety comes first, saving money second.
