answer:Although I’m not very familiar with them, there are a few apps for the Mac that allow you to quickly view the output of a connected webcam as a live video (particularly useful for the door) and it will continually take snapshots in the background every specified period (30 seconds? Useful for the front windows) saving them as images to your drive. This is particularly good, as a 24/7 running video would quickly become huge. My thinking is basically, use a very long USB cable (as an extender, to which the webcam is plugged in) to attach the device. An iSight would look particularly cool as a security camera, if you can get hold of one. If it’s not an iSight, then make sure that a Mac OS X driver is available for it. Not to mention, use a strong security cable to connect the Mac you use for security to the wall or floor (or at-least the external hard drive it’s saved on). The footage you gather is useless if you can’t get a burglary conviction because they took it with them. :) If I remember the name of the app I’ll post it here.
