has anybody ever come across an open circuit board-type camera that didn't operate on 12vdc? i have an unknown board camera that an engineer gave me to play with, but no documentation.. i don't even know if it's color or b/w. it has no connectors soldered to it, just 3 wires (red, black, brown) i'm assuming the video signal ground is combined with the electrical ground on the black wire, red is power, brown is video signal.

Do you have a picture?

i figured it out, it is 12vdc. it's also black & white and very grainy... i suspect it's one of the first generation board cams.
