Push notifications for

[Zorra2]

Hi all,

I’m troubleshooting a Dahua NVR/DMSS issue after changing internet provider/router.

Setup:

• Camera 1: connected directly to the NVR PoE port
• Camera 2: connected via a separate switch/mesh point

What I fixed so far:

• Camera 2 was still on the old network
• Using the NVR “Modify IP” function, I changed camera 2
• Camera 2 now works when added manually in DMSS, so the camera itself seems reachable. Thank you @bigredfish

Current problem:

• Live view works.
• Motion detection notifications are received in DMSS.
• But when I tap the motion event, DMSS says: “Video not found”.
• In playback, the NVR only shows recordings up to around <span>14:49</span>; nothing newer appears. (it is 16:43 here)
• This problem is happening with camera 1, which was not moved to the new network. I only updated its firmware.

Settings checked:

• Recording schedule for channel 1 appears enabled for General/Motion/IVS across the day.
• Record control is set to Auto for main stream and sub stream.
• HDD status is Normal and Read/Write.
• HDD is full: <span>0 GB / 3.58 TB</span>.
• “HDD full” is set to Overwrite.
• Quota is disabled/off.
• NVR date/time is correct.
• IPC time synchronization is enabled.

Question:
What else should I check when live view and motion alerts work, but the NVR stops recording and playback only shows footage up to an earlier time?

Could this be a recording database/overwrite issue after firmware update? Should I reboot the NVR first, try manual recording, rebuild/repair the database, or format the HDD as a last resort?

Thanks in advance.

Always reboot first

I have had similar gaps in recording when switching cameras, and when a camera failed to get a time synch update from the NVR for hours before I noticed it...see if it resolves after the reboot and after midnight once the date changes
