Buy Hardware to Build Hardware

For this project a pair of A2200 Canon cameras will be used. Choice for them was made because they are light, cheap, have a 14 MP sensor, can shoot 720p (HD) video and come in red & blue colors.

But most importantly, since this is Canon (and that is why we love them for it), they can be used with an third-party firmware called CHDK (Canon Hacking Development Kit), granting full control over the cameras including running scripts on them and controlling them remotely trough a computer.
