Motion Capture with... Motion!

If you are considering a video security system, don't bother buying a special security video tape recorder. Instead, install Linux on an old PC, and set up a great piece of software called Motion.

I installed Motion on an old K6-233 running Linux Mandrake 10.1, and configured it to capture frames from a Lorex Video Camera. Unlike regular webcam software, Motion only saves images if it detects motion in the frame. Once you have the images, you can do anything you want with them (like browse them through a web browser).

I wrote a couple of bash scripts that take a full day's set of motion capture images and create a time-lapsed QuickTime movie of the day's activity. Pretty cool to watch a movie of a full day pass in just a few minutes!
