Make sure you have a plan on how to attach the camera. If you want to just send it back to the dashboard, you can get an ethernet camera and wire it up to the radio. However, if you want to process it, you may want to get some sort of analog camera, since the C RIO only has two ethernet ports. I'm not sure if some sort of ethernet splitter would work, though.
Also whenever I see an apostrophe misused, I die a little. Actually, I just kind of cringe, which could be considered dieing.
