(World-Wide Web camera) Any video camera whose output is available for viewing via the Internet or an intranet. Typically a webcam would be a slow-scan CCD video camera connected to a video capture card in a computer. Images from the camera are captured periodically and made available on a web page.

Webcam(WEB CAMera) A video camera that faces the user. Webcams are built into laptops but are separate units that attach to the monitor of a desktop computer. A Webcam is used for video calling and taking selfies, and although most models include a microphone, many users opt to use headphones for better audio quality. Stand-alone microphones with greater sensitivity are also used for studio presentations.
Webcams, Network Cameras and Home Cams
A Webcam is attached to a computer, whereas network and connected cameras are stand-alone units used for monitoring. Typically a "network camera" is part of a complete surveillance system with several cameras for stores and offices (see network camera). A "home cam" plugs into the home network like a printer (see connected camera). See Webcamming, Webcam blocker, POV camera, lifecasting and spycam.
|Desktop and Laptop Webcams|
|Unless a desktop computer is an all-in-one, the Webcam is a separate unit that clamps onto the top of the monitor as in this example (top). Laptops come with camera and microphone at the top of the screen (bottom).|
