I built this self-contained, motion detecting, remotely accessible CCTV system. Runs Ubuntu, built with super-low form-factor Raspberry pi system and lego. 2 x playstation3 eye cameras with 8 microphone array. "Motion" software running multi-threaded config. Stores snapshots and time-lapse locally and shares motion events via dropbox (for linux) from both cameras independently. Viewable remotely via iPhone app and web. Total cost: £50, nearest equivalent commercially available device: £300.
