The quality of the image or video is one of the most important specifications that you should pay attention to when thinking about acquiring a webcam, as it is the guarantor of sending and receiving clear images. Noting that web cameras fall into two main categories in terms of image quality or resolution:
- Standard Definition camera; Usually the resolution of these cameras is modest, and in most standard cameras the resolution is 480 pixels for vertical scan lines, or 480 x 640 pixels for the overall resolution.
- High Definition Camera; As for the resolution of high-quality cameras, they are available in the market in two models, the first has a resolution of 720 pixels (or 720 × 1280 pixels for total resolution), and the second has a resolution of 1080 pixels (1080 × 1920 pixels for total resolution), which are cameras called full HD, for the lines Longitudinal scanning, noting that the resolution of the cameras and videos increases with the increase in the number for resolution, meaning that the cameras that have high resolution numbers give pictures and videos of higher quality and greater resolution.
