  • On-demand system and method for retrieving video from a commercial vehicle
    Patent number: 10204159
    Abstract: An apparatus for use with a commercial vehicle comprises a media recorder configured to receive video from one or more cameras. The media recorder comprises a memory configured to store a loop of the video as a circular buffer having a predetermined duration. A transceiver is communicatively coupled to the media recorder and configured to receive a video request command generated at a central office. An event detector is configured to communicate with a vehicle computer and detect predetermined events occurring during vehicle operation. The media recorder is configured to retrieve a portion of the loop of video stored in the memory and the transceiver is configured to transmit the portion of the loop of video to the central office in response to the video request command.
