WEB CAMERA
Definition of: Webcam
(WEB CAMera) A front-facing video camera that attaches to a computer typically via USB or that is built into a laptop or desktop screen. It is widely used for Skype and other video calling software as well as to continuously monitor an activity and send it to a Web server for public or private viewing. Webcams purchased as separate peripherals generally have a microphone built into the unit, or an external mike comes in the package.
Webcams Vs. Network Cameras
A Webcam attaches to, or is built into, the computer, whereas a "network camera" is a stand-alone unit that connects to an Ethernet network. While the Webcam is commonly used for videophoning with another user, network cameras are used to monitor locations such as stores and offices.
VIDEO CAMERA
A camera that takes continuous pictures and generates a signal for display or recording. It captures images by breaking them down into a series of lines. For example, NTSC, the U.S. and Canadian analog standard uses 525 scan lines. Each line is scanned one at a time, and the continuously varying intensities of red, green and blue light across the line are filtered out and converted into a variable signal, which is most often converted to digital.
Although many models of analog camcorders and equipment are still available, the industry has long since switched to digital for video capture.
