Installing multiple outboard cameras for maneuvering safety

Ours goes through the Aladdin System and is adequate. It was a factory install...one rear camera, two side cameras and one inside camera. I also have a monitor in the bedroom that, when activated, activates the back up lights, dock lights and four exterior lights along with the cameras. Hear a noise and I can light up the night without ever leaving the bedroom.....the side cameras come on with the turn signals and the rear camera automatically comes on when shifted into reverse....Dennis
