Good day,

Thanks a lot for your time and patience.

Sorry for the delay.

For your case, would you please help me check the following details:

1. What is the model number of your NVR?
2. Would there be any error message when Tapo C200 failed to work with NVR?
3. Are you able to remote control the Tapo C200 on the 4G via Tapo APP?
4. By the way, what is the model number of your home rouyer?

Thanks a lot.

Hello,

Here are the answers to your questions :

1) Zxtech MN401PN

2) No messages, just "connecting" and never any stream loading, compared to other cameras.

3) Yes, the Tapo C200 works fine over 4G/5G remotely

4) Technicolor TC7210

Thank you
