I bought this 10 Channel 4K NVR and 6 Wi-Fi Cameras a few weeks ago. I also bought and add-on doorbell (WM-2DBWNPM). I am disappointed that the doorbell will not connect to the NVR as stated online. Overall, the system works as it should. Very nice clear picture.

That doorbell is compatible with your system. Please refer to your product manual at the link below. There is a section for Adding new devices to your recorder which details the steps.
