  • Patent number: 10668859
    Abstract: A commercial trailer camera interface for providing an apparatus and method for connecting video cameras and data buses from a trailer to the tow vehicle. The trailer camera interface generally includes a nose box, which affixes to the front of the trailer, a tail box which affixes inside the rear of the tow vehicle, and an umbilical cable which connects the nose box to the tail box. The nose box encodes the video signals, for example as differential signals, for transmission over the umbilical cable and the tail box decodes the received encoded signals to recover the video signals. The nose box and the tail box may each include a plurality of video camera connectors. The tail box may include a video handler to display or record or stream the video signals.
