MOVE Action is an open source application that monitors your webcam and can take some action when movement is detected. The action could be to Lock your PC (requiring a password to reactive it), save a JPG image to disk, play a WAV sound file or run an external application. It checks the webcam at particular intervals and compares the current image with the previous one, or against a "base image" that you Capture by clicking a button. If there is a significant change detected Between images the program will take the configured action(s).
