 | A camera connected to a computer or server that allows anyone connected to the internet to view still pictures or motion video of a user. The term webcam is also used to describe the low-resolution digital video cameras designed for such purposes, but which can also be used to record in a non-real-time fashion. .
Webcam software typically captures the images as JPEG or MPEG files and uploads them to the Web server either continuously or at regular intervals.
Videoconferencing cameras typically take the form of a small camera connected directly to a PC. Analog cameras are also sometimes used (often of the sort used for closed-circuit television), connected to a video capture card and then directly or indirectly to the internet. |
