Raspberry Pi is a quite powerful, versatile board and it offers a lot for the $35 price. I bought & configured one for a NAS + miniDLNA server and it works surprisingly well.

Because I wanted to be able to access the video stream from pc & mobile, I went for an implementation with Node.js as server and a responsive web page as client.
The project is designed as an end to end solution that, besides offering a live video stream, also actively monitors for movement with the help of a PIR sensor: if an Alarm is triggered, you get a SMS notification on your phone and the snapshots taken during the Alarm time span (customizable) are uploaded via FTP to your server.
