Recently, wireless cameras have started to appear. They consist of a camera at the back of the trailer linked wirelessly to a monitor in the tow vehicle. However, the system still isn't truly wireless because the camera needs to be powered as does the monitor. Therefore, all that is being eliminated is the wire running the length of the trailer, at the expense of more complicated wiring at both ends.
AmeriCam, based in Silicon Valley Calif., has now addressed the problem with its patented single cable installation technology. In essence, a discreet MicroBlock camera is mounted at the back of the trailer and a single 3/16-inch cable is fed to the front. A waterproof IP68 rated connector sits alongside the tow vehicle's standard 7 pin connector and the system control unit is mounted in the back of the tow vehicle. A similar small cable is fed to the front of the tow vehicle and connected to a high quality 3.5-inch monitor. The end result of this approach is a camera in the tow vehicle which is ideal for hitching up and daily use as a backup camera, and a second camera at the back of the trailer for an unobstructed view there. Both cameras work seamlessly and automatically depending on driver preference and configuration.
