Cannot View Playback Footage?

1. Check the recording settings to ensure they are configured correctly:

    

   Go to Main Menu > Setup > Record and verify that recording is enabled for the corresponding camera channels. Also, check if Recycle Record is turned on.

1. Check the recording mode on the live view interface:
   • If Start Record is selected, the system is set to 24/7 Continuous Recording by default.

• If Stop Record is selected, the system uses Alarm-Triggered Recording. In this case, go to Main Menu > Setup > Schedule and confirm that the recording schedule is set for the desired time periods.

1. 

   Verify the detection function settings:

    

   Go to Main Menu > Setup > Alarm and check that Motion Detection, Human Detection and Vehicle Detection are enabled as needed.

    

1. Check the hard drive status:

1. 

   Right-click on the live view to open the Main Menu, then go to Setup > Disk Management to check if the hard drive is recognized normally, with correct capacity and in a Read & Write state. If not, power off the NVR/DVR, open the casing, and re-plug the SATA and power cables of the hard drive.

2. If the hard drive is recognized but recording still fails:

1. Go to Disk Management and format the hard drive to clear existing playback data (note: this will delete all historical recordings).

2. If the issue persists, try replacing the hard drive inside the NVR/DVR.
