MS Lifecam is the first consumer webcam to support 720p video at 30fps. That’s the full 1,280×720, unlike some other attempts at so called HD video for some 2 Megapixel webcam’s that only managed 960×720 which isn’t really HD.
Other features include a glass lens, auto focus, 4x digital zoom and a digital, noise-cancelling microphone that is mounted on the top of the camera. Microsoft has also implemented what it calls ClearFrame technology which is meant to deliver smooth, detailed video, although we’re not quite sure what this does.
