A webcam allows digital cameras to capture and transfer still images and video over the internet. Higher frame rates of at least 15 frames per second are needed for streaming video. Webcams are used to monitor homes, watch pets, and let families remotely see babies and grandparents. Software allows video calls and conferencing between users. New 3D webcams like the Minoru use two spaced cameras and glasses to provide 3D images for a more natural video chat experience, though some question the professionalism of using glasses.
