A recording device comprising:

• a receiver configured to be connected to an ambient imaging device and an in-vehicle imaging device, the ambient imaging device generating ambient images of a vehicle in time series, the in-vehicle imaging device generating in-vehicle images of the vehicle in time series, the in-vehicle images including an image of an occupant of the vehicle;
• a recorder configured to record the ambient images and the in-vehicle images received by the receiver;
• and
• a display,
• wherein the recording device selects a first image from the recorded images, the recorded images including the ambient images recorded in the recorder and the in-vehicle images recorded in the recorder, the first image indicating a first behavior corresponding to an apparent risk to the vehicle, the first behavior including at least one of a behavior of the vehicle or a behavior of the occupant of the vehicle, and the apparent risk corresponding to a behavior change of the vehicle,
• wherein the recording device selects a second image from the in-vehicle images recorded in the recorder, the second image indicating a second behavior corresponding to a potential risk stemming from a behavior of the occupant of the vehicle, the potential risk not corresponding to the behavior change of the vehicle, the second behavior being classified into one of a first risk level or a second risk level different from the first risk, and
• wherein the display is configured to display the second image of the second behavior corresponding to the second risk level of the potential risk, and configured not to display the second image corresponding to first risk level of the potential risk.
