I know a guy who bought a three pack of Uniden security
cameras from a big box store for less than a couple hundred bucks which include IR night vision. He mounted them on the bow, masthead, and at the stern.
He said he used the bow one at night to navigate the ICW
. Showed us video of the stern camera facing our boat
behind him at the dock
