These are web cameras with IP addresses, which send a continuous stream of pictures in the Motion JPEG format. These feeds are checked every three hours or so. 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.
These videos are most likely copyrighted by whoever owns the cameras. The snapshots you see here appear as fair use according to copyright law. However, if a picture from your webcam appears here and you object to that, let us know and it will be removed.
