Does anyone know of a good program to record webcam footage? I'd like to get an iSight or other webcam and put it in the window beside my front door to record who comes up to the door. I've been having a problem with nosy neighbors messing with mail recently. I have a Mini I could dedicate to this project, basically what I want it to do is just record constantly to the hard drive, automatically erasing after, say, a week or so. Ideas?
