However, since there is no further charging in the parking mode, the black box is driven only by the vehicle battery, There is a problem that the vehicle battery is discharged when the battery is consumed a lot.

A conventional video surveillance apparatus is disclosed in Patent Document 1. Such a video surveillance apparatus includes a vehicle battery; A low power auxiliary power supply for supplying power from the vehicle battery to the low power auxiliary power; An impact sensor driven by a low-power auxiliary power source of the low-power auxiliary power supply and detecting an impact from the outside when the vehicle is impacted and outputting a main power supply start signal; A main power supply unit for supplying power supplied from the vehicle battery to the main power in response to a main power supply start signal of the impact sensor; A control unit operating in a parking recording mode by a main power supply of the main power supply unit and outputting a photographing start control signal in the parking recording mode and storing an input video signal; An image sensor for photographing a predetermined area in response to an image pickup start control signal of the control unit and outputting an image pickup signal; An image signal processing unit for processing the photographing signal input from the image sensor in response to the photographing start control signal of the control unit, converting the photographing signal into a video signal, and transmitting the signal to the control unit; A storage unit for storing the video signal under the control of the controller; And an alarm unit for generating an alarm sound in response to the alarm sound generation control signal of the control unit, wherein the storage unit comprises: a first storage unit for storing a recording video signal generated in the normal recording mode; And a second storage unit for storing signals. However, when an external impact is applied to the vehicle, it is switched to the recording mode to record the surrounding environment of the vehicle. Thus, there is a problem that the image before the external shock is applied can not be confirmed.
