This GoPro housing uses ONE cable to provide power to the GoPro camera (Hero2,3,3+,4) AND it has live video feed out from the camera to your monitor on land in standard definition. We were able to figure out how to get up to 300 FEET of cable length! Camera records as it normally does in HD. You provide a 12v power supply DC and the housing converts to 5v USB internally.
