A dashboard camera acquires video data from a camera that captures the surroundings of a vehicle, acquires sensor data including at least one of acceleration, speed, and angular velocity of the vehicle, gives time information indicating time of acquisition to each of the video data and the sensor data, and transmits the sensor data to a data analysis server when an event occurs in the vehicle, the data analysis server identifies the content of the event occurred in the vehicle based on the sensor data and transmits an identification result to the dashboard camera, and when the identified event is determined to be the predetermined event, the dashboard camera specifies video data to which time information same as the time information given to the sensor data used for the identification is given, and transmits the specified video data to a video accumulation server.
