My free web cams
When "captured" by the computer, the video stream may be saved, viewed or sent on to other networks via systems such as the internet, and emailed as an attachment.When sent to a remote location, the video stream may be saved, viewed or on sent there.Explanation These are web cameras with IP addresses, which send a continuous stream of pictures in the Motion JPEG format. The first frame of the video is grabbed and resized as a thumbnail.The general location is at first guessed based on the IP number, but can be edited by whoever has better information.
Webcams have been used for augmented reality experiences online.
Unlike an IP camera (which connects using Ethernet or Wi-Fi), a webcam is generally connected by a USB cable, or similar cable, or built into computer hardware, such as laptops.
The term "webcam" (a clipped compound) may also be used in its original sense of a video camera connected to the Web continuously for an indefinite time, rather than for a particular session, generally supplying a view for anyone who visits its web page over the Internet.
For example, the position of a single light source can be tracked and used to emulate a mouse pointer, a head-mounted light would enable hands-free computing and would greatly improve computer accessibility.
This can be applied to games, providing additional control, improved interactivity and immersiveness.
