A webcam is a video camera that feeds or transmits your image in real time to a computer or through a computer. When "captured" by the computer, the video stream can be saved, viewed or sent to other networks through systems such as the Internet, and sent by email as an attachment. When sent to a remote location, the video stream can be saved, viewed, or sent there. Unlike an IP camera (which connects via Ethernet or Wi-Fi), a webcam is usually connected via a USB cable, or similar cable, or built into computer hardware such as laptops.
The term "webcam" (a trimmed compound) can also be used in its original sense for a video camera connected to the Web continuously for an indefinite period, rather than for a particular session, generally providing a view for anyone who visits your page Web through the Internet. Some of them, for example, those used as online traffic cameras, are costly and robust professional video cameras.
