A webcam is a video camera that feeds or streams an image or video in real time to or through a computer network , such as the Internet. Webcams are typically small cameras that sit on a desk, attach to a user's monitor, or are built into the hardware. Webcams can be used during a video chat session involving two or more people, with conversations that include live audio and video. Webcam software enables users to record a video or stream the video on the Internet. As video streaming over the Internet requires much bandwidth , such streams usually use compressed formats.
