I put together a system to record video in the cockpit.

You will want to mute the sounds - too noisy. Not sure what I'll do about that yet.
The system is open-loop. I only see what I got after I shut the thing down and download the video to a computer... no video screen in the system. Yet.
The system consists of an outdoor "bullet" or "lipstick" camera connected to a small security system video recorder that writes the data to an SD card. The camera is powered by a 12V battery made up of 8 D-Cells. Recorder runs off of two AA's.
Recorder and battery are housed in a pelican box stowed in a convenient place.
I have some more video I plan to post later. Eventually I hope to come come up with something more interesting that two guys moving back and forth across a boat... any ideas for camera views are encouraged.
