(WEB CAMera) A video camera that attaches to a computer typically via USB or that is built into a laptop or desktop screen. It is used mostly for videophoning over networks such as Skype as well as to continuously monitor an activity and deliver the video to a Web server for public or private viewing. Webcams have been set up that stream video continuously to a Web site, capturing virtually anything, including a dorm room, a street corner, an interesting outdoor view and, of course, pornography, the latter inspiring programmers in the 1990s to greatly improve Webcam software.
Webcams purchased as separate peripherals generally have a microphone built into the camera body, or an external mike is part of the package. If a laptop or desktop computer comes with a Webcam, the microphone is included.
Webcam Vs. Network Camera
A Webcam attaches to a computer, whereas a "network camera" hooks into an Ethernet network. The network camera offers higher resolutions for the same applications as a Webcam, but tends to be more costly (see network camera). See lifecasting and spycam.
