Model: Tapo C500   Tapo C200  
Hardware Version:
Firmware Version:

I have 1 C500 and 2 C200 cameras (latest firmware) on my network.

Cameras are set up for UTC-5 (eastern time). All times on cameras are OK.

After I installed a Tenda N3L-8H V1 (firmware 12.1.8.10), I connected 1 C500 and 1 C200 to the NVR.

NVR is also configured for UTC-5 (eastern time).

The time displayed on the C500 and the connected C200 changed.  (-10 hours)

The time on the other C200 stays the correct time.

When I look at the recording, the NVR shows the correct time, but the time on the recording is -10 hours.

I have read various reported problem on the forum but nothing seems to fit my problem.

 

Any help would be appreciated.

 

Thanks.

 

Raymond

  @Wayne-TP 

Received an e-mail from Cleon (system engineer) who indicated a new firmware had been created for my C500 camera.

I downloaded it and tested.

PROBLEM FIXED ON THE C500.

He said that if the firmware fixed my problem, they would create a new firmware for my C200 camera.

GREAT work and GREAT support.

 

Regards.

Try to disconnect the NVR and restart the camera, check if the time re-syncs correctly. 

 

What are the hardware and firmware versions on your cameras?

C500 version 1.0 firmware 1.3.4 Build 250228 Rel.66111n

C200 version 5.0 firmware 1.1.8 Build 250310 Rel.73289n

 

If I unplug my NVR and restart my camera, the time comes back  ok.

As soon as I plug the NVR, the time changes (goes back 10 hours).

If I restart a camera while watching the NVR display, the camera goes offline

ant the time is OK for 1 second and then goes back 10 hours.

 

Regards

I have set "DIAGNOSTIC ON" in the setting and restarted the camera. On the restart, you see the proper time at startup and then the time goes back 10 hours.

How can I include the log file in the forum.

 

Thank you

 

Raymond
