Webcam Watcher

Website: http://www.webcam-watcher.com/wcw_code.html
License: Freeware (previously shareware but now development is "abandoned" and a key for all to use has been released)

Webcam watcher was originally shareware but the author has released it as freeware and posted a key usable by all on his website listed above. Webcam watcher will monitor multiple images for changes with built in motion detection.

For those without always on internet connections the ability to continue to capture while traveling would be useful.
