How do I setup a surveillance system for in my room?

Hello,

I’d like to turn my always-on Mac to a room-surveillance system. Like when it detects motion it starts recording the video to a folder, and when the motion stop, it stops recording.

So it must capture video, not only pictures, and with that video, it must record audio too!

In addition, I would like a kind of web-interface, like a activate/deactivate functionality protected with a password. This isn’t really necessary, but kind of fun.

Don’t ask me why I want this. This is personal.

Thanks, Davey.
