Video Pro not able to set up

Bought video pro for new house. Installed NICOR PRCP1 digital doorbell that says compatible with Ring. I get 20vac at door where install to occur. When attached to wires, the doorbell begins ringing about every 45 - 60 seconds. I have a solid white light about three fourths around pushbutton. 9-12 quadrant dark. I tired hard reset and every other suggestion. Do I need to connect the power pack supplied with doorbell? I thought the digital doorbell eliminated the requirement for the powerpack. Never have been able to get a wifi signal or a flashing indicator light, but plenty of frustrating rings while reading install instruction repeatedly.
