WOW! This is slick. Logitech has published a sidebar gadget that works as a motion detector. When you click the play button it starts watching for motion. Any movement gets recorded as a video and placed in your videos folder. It works! Try it out! The only caveat I've found is to leave the resolution as default. I cranked it up to 800x600 and it crashed when I activated it. Resetting it to 320x240 fixed the glitch.
Now I can finally prove to my wife it's HER dog that chews up the garbage, not mine... 😉
