What is the best resolution for a dash cam?

1 Answers

The optimal resolution for a dash cam is 1080P. Compared to other resolutions, 1080P records clearer videos than 720P but is slightly inferior to 1200P. However, higher resolution results in larger video file sizes, with 1200P files being larger than 1080P. Therefore, 1080P is currently the best resolution for dash cams. Dash cams are designed to record driving processes, and the clarity of the recorded video is crucial. The most important performance indicator for video clarity is resolution, which refers to the number of pixels per inch. Thus, the resolution depends on the pixel size. Generally, when the display size of a dash cam is fixed, larger pixels result in higher resolution and clearer images. For dash cam pixels, the front cameras of dual-lens dash cams typically have 5 megapixels or 12 megapixels, while the rear cameras usually have 2 megapixels or 5 megapixels. Clarity is mainly divided into standard definition and high definition, with high-definition dash cams offering resolutions such as 720P, 1080P, and 1200P. The specific resolution can be chosen based on the memory card capacity. Larger capacities allow for higher resolutions. For example, a 16GB memory card can record approximately 200 minutes of video at 720P resolution, but only about 100 minutes at 1080P. Larger memory cards store more videos for longer durations. When purchasing a memory card, it is recommended to choose one with a read/write speed of Class6 or higher, preferably Class10, to ensure better video quality. Additionally, opt for genuine, reputable brands for better quality and reliability.
