The Genius WideCam F100 has a maximum video resolution of 1920 x 1080 pixels. That's over two times the video resolution of a 1280 x 720 pixels webcam, which is the most frequently found video resolution.
A 1920 x 1080 pixels maximum video resolution is actually the best video resolution amongst all similar spec webcams that have been around for more than two years.
A 640 x 480 pixels maximum video resolution is the worst video resolution across similar types of webcam.
We think you might also be interested in some of the other webcams that have a video resolution of 1920 x 1080 pixels currently available including the Logitech C910, or the Creative Labs Live! Cam Connect HD which has a better Rating.
