1. A vehicle event recorder system configured to couple with a vehicle, the system comprising:

  • a camera configured to acquire visual information representing a vehicle environment, the vehicle environment including spaces in and around an interior and an exterior of the vehicle;

    one or more vehicle systems transducers configured to generate output signals conveying vehicle usage information, the one or more vehicle systems transducers forming at least part of an on-board databus system, the vehicle usage information including information related to one or more of a drive-train, a transmission, an engine, brakes, or lights of the vehicle;

    a managed loop memory configured to electronically store information;

    a buffer memory configured to electronically store information;

    a transceiver configured to wirelessly transmit information to a remotely located server via a cellular communication network; and

    a microprocessor configured to;

    effectuate storage of the visual information and the vehicle usage information in the managed loop memory;

    responsive to physical anomaly event triggers, transfer the visual information and the vehicle usage information electronically stored by the managed loop memory to the buffer memory in detailed complete datasets that correspond to individual physical anomaly event triggers;

    compress and/or parse the detailed complete datasets into abbreviated datasets such that the abbreviated datasets comprise less bytes of data than the detailed complete datasets;

    effectuate storage of the abbreviated datasets in the buffer memory, andfacilitate wireless transmission of the detailed complete datasets and the abbreviated datasets via the transceiver,wherein transmission of the abbreviated datasets is prioritized over the detailed complete datasets such thata high priority individual abbreviated dataset associated with a single vehicle physical anomaly event trigger is transmitted instantly via the cellular communication network, and thena lower priority individual detailed complete dataset associated with the same physical anomaly event trigger event is transmitted responsive to a higher bandwidth link becoming available.
