Abstract:
A vehicle-mounted device for capturing video imagery in response to a triggering event, comprising:a housing; an image sensor mounted to said housing, said image sensor sensing optical phenomena representing said video imagery; a data sensor circuit within said housing and in part responsive to said triggering event; and a capture circuit within said housing; said capture circuit comprising: a non-volatile memory; a volatile, random-access memory configured as a continuous-loop buffer, said volatile memory coupled to said non-volatile memory and coupled to said image sensor; said volatile memory capturing a signal representing said video imagery from said image sensor in a first-in, first-overwritten manner, and, responsive to said data sensor circuit sensing a triggering event, terminating capture of said signal and copying the captured signal representing said a video imagery to said non-volatile memory.
