What is the reason for the loss of monitoring video playback?

1, the set video is a motion detection video, which is recorded only when the picture is active and not recorded when there is no change, so the played back image is intermittent.

2. There is something wrong with the hard disk, and there is something wrong with writing or watching videos; Or the video host fails and restarts constantly, resulting in video discontinuity.

3. If it is a network video recorder, it may be that the network bandwidth is insufficient, and some images will be lost due to insufficient bandwidth, resulting in abnormal parking of video recorder images.
