For example, 10 km / h.

The threshold value for the distance, the threshold value for the impact value, and the threshold value for the speed change amount for each driving speed may be set by a user, a vehicle manufacturer, or a provider of a vehicle monitoring system.

When it is determined that the collision is determined by the determination unit 810, data temporarily stored in the buffer unit 840 for a predetermined time, for example, 30 seconds, before the collision is transferred to the data storage unit 850, and at the same time, the control unit The data stream from 830 is delivered directly to the data storage 850 and combined with the data transmitted from the buffer 840 to be stored in real time.

Data stored in the data storage unit 850 may be transmitted to the vehicle monitoring server 200 through the data transmission unit 860 to check the stored data.

The data transmitter 860 transmits the data stored in the data storage 850 to the vehicle monitoring server 200.
