The I-frame interval determines the size of a video GOP, which is a group of consecutive pictures. In addition, a motion detection backtracking duration is set, and the backtracking duration is set to be an integral multiple of the time interval of the I frame, namely n × g seconds, which also means that n × g seconds are backtracked forward when motion detection is triggered to record, wherein n is an integer greater than or equal to 1. A trace back buffer is also provided, the size of which depends on the above parameters, e.g. the size of the trace back buffer can be set to n × g × f frames.

If two or more trace back buffers are provided, these trace back buffers are defined as sub trace back buffers. When the recorded current video is stored, whether the stored amount of the current sub-backtracking buffer reaches a second preset threshold value is detected, if not, the current video is continuously stored in the sub-backtracking buffer, if so, whether a blank sub-backtracking buffer exists is detected, if so, the current video is stored in the blank sub-backtracking buffer, if not, the sub-backtracking buffer with the earliest storage time is searched in all the sub-backtracking buffers and is used as a target sub-backtracking buffer to be covered, the recorded current video is covered on the stored video with the earliest storage time in the target sub-backtracking buffer, and the backtracking buffer is set to be a circular storage rule when two or more. The second preset threshold is the maximum value of the storage capacity of the sub-traceback buffer area preset according to the size of the sub-traceback buffer area.

after the mobile detection video is recorded and the backtracking video is obtained, the mobile detection video and the backtracking video are processed, namely, the backtracking video is in front, and the mobile detection video is spliced after the backtracking video is in back, so that a complete mobile detection video file is obtained. The mobile detection video file comprises a backtracking video with preset backtracking duration and a mobile detection video, so that the influence of the delay problem of the mobile detection video is avoided, the key information is prevented from being missed, and the monitoring is safer.
