1. In combination:

  • a vehicle; and

    an event recorder mounted to said vehicle comprising;

    a wave pattern detector for detection and recognition of the presence of a predetermined wave produced external said vehicle, and for producing a trigger signal denoting predetermined wave presence;

    a plurality of sensors, including;

    first image sensing means for sensing optical images and for producing a first image sensor signal representing the sensed images; and

    sound sensing means for sensing sound and for producing a sound sensor signal representing the received sound;

    a persistent memory device; and

    a capture circuit connected to said sensors for receiving and capturing the sensor signals therefrom, connected to said wave pattern detector for receiving a trigger signal therefrom and for terminating capture of the sensor signals within a predetermined time period upon receipt of a trigger signal therefrom, and connected to said persistent memory device for loading the captured sensor signals therein.
