NVR not showing live preview

No, it's totally empty

I do not think your cameras are outputting a sub stream.
You will need to login to the camera and adjust sub stream settings.

I don't know how to go, since the options are only on the phone, via the App

 

[DS22051999]

i have tried but there is no option as far as the options you mention

 

[DS22051999]

I can send you an image of the options I have on the phone APP

How are they plugged into the NVR?
Does NVR have a built in switch or do you use a separate network switch?

You will need to use a computer to configure them.
ONVIF setup does not work with a phone app.
