Intelligent face-tracking software automatically follows you to keep you in view. It even zooms in so you can see details clearly. It's easy to add live video to all your IM sessions. The QuickCam Sphere also features a new 1.3 Megapixel sensor with RightLight technology to capture finer, more accurate details, achieving superior quality videos and pictures.
