Abstract

The present invention relates to a vehicle black box system for photographing, storing, and storing driving information such as a speed and a brake condition, A black box for storing a video signal including a time before and after the occurrence of a collision in a predetermined amount of time, a keyboard provided with a plurality of keys, and a video signal to be photographed, And an output means for displaying a stored video signal. Therefore, when an accident occurs due to a collision between vehicles or between vehicles and a person, it is possible to clearly identify an error by checking an automatically recorded video signal and a driving state of the vehicle, thereby maximizing the function of the vehicle.
