The camera can't see the playback. What's going on here?

1. The reasons why the camera can't play back are as follows: If the surveillance camera is only connected to the monitor and not connected to the hard disk recorder, the video image is not stored, so it can only watch the real-time picture and can't play back. Although the surveillance camera is connected to a hard disk video recorder, the hard disk storing the video image is out of order and cannot be played back.

2. There may be several reasons why the camera can't play back: First, the hard disk is damaged. Check whether the hard disk status is wrong in the hard disk management menu. If there is no important video, you can format the hard disk, which may be repaired. Second, there is a software problem. When searching for video, the machine crashed, and it can be normal after restarting.

3. The reason why the monitor can't see the playback: the monitor camera is only connected to the monitor, not to the hard disk video recorder, and the video image is not stored, so it can only watch the real-time picture and can't be played back. The surveillance camera is connected to the hard disk video recorder, but the hard disk storing the video image has an internal fault and cannot be played back.

4. The storage device in the monitoring system is an important part of video playback. If the storage device fails, the reasons for the failure of the storage device may be hard disk damage, memory card damage, memory chip damage and so on. These failures will cause the storage device to be unable to read data, which will lead to the failure of monitoring and playback.
