Abstract
The present invention is related to a digital video recording method, and in particular, when a recording mode is audio detection, according to an audio signal transmitted from a mike mounted on a camera or a mike mounted separately, this method records the video taken by said camera during the time period for which a recording speed and video resolution is already set as super-high speed and high video resolution. After the elapse of an already set time period, when the audio signal is sensed, this method records the video by varying the recording speed and video resolution from super-high speed and high video resolution into low-speed and low video resolution at a time interval which is already set. Therefore, it becomes possible to obtain the specific information about the video data which is important in an unmanned security system.
