iSpy - Turn your computer into a surveillance system

Very interesting open-source application - though they charge a small subscription fee for additional features available through the web site - which uses your web or IP cameras, microphones etc. to monitor movements and activity in your home, business or any other building. Video feeds and alerts are available remotely from virtually any point in the Universe with an internet connection. Awesome!

Here is how it works:
