My Hikvision video doorbell won't register with the NVR either, I keep getting a message that the 'Certificate Verification Failed'
I have 3 EZ-Viz wireless cameras connected to the NVR... 2 of them are fine but the DB1C doorbell is not connecting... status shows "Certificate verification failed".
Under "Edit Device" on the NVR for the DB1C, I see there is a "Verify Certificate" button that is not checked?... tried checked/unchecked does not help... don't know if this was there in the V4.0 GUI.
The "Certificate verification failed" status occurred for both a Hikvision DS-HD2 and an EZ-Viz DB1C doorbell.
Even though I had "Verify Certificate" unchecked...

I have added the doorbells (hopefully temporarily) using the HIKVISION_RTSP protocol...
