Hi,

Same network as camera

Checked that IP didn't change

Address reservation is set (with open ports)

No other software is used when testing

DVR running latest firmware

Didn't subscribe to Tapo service care

No SD card.

Thanks,

This is the reply from them,

 
"Thanks for contacting us. This is Alex from ANNKE Technical Support.
 

The DVR can connect IP camera. But the IP camera should meet the two requirements below.

1. The IP camera must support the ONVIF protocol.

2. The IP camera's resolution had better equal to or lower than the resolution DVR.

3. The camera should be connected to the router, by cable, or by wifi. Therefore, a wireless camera is also OK.

After checking, the resolution of the camera is 3mp, but the DVR is 2mp, I am afraid it is not compatible with the DVR.

 
I am looking forward to your reply.
Any other problems, please feel free to reach out."
 

I have got it to work on a HIKVISION NVR but I have a weird issue on that one, the recording stops randomly and then starts at a random time, even thou it is set to record continuously.
