Free Motion Sensor

Question

I'm planning to make DIY Home Surveillance. Now I'm looking for free motion sensor. I'm using webcam as a camera to detect whether there's a motion changes in my house. Does anyone know what is the best free motion sensor software? Also I want the software emailed me if someone tried to breach my house. Currently I'm using PC with Windows as its Operating System.

Thanks
