We don't do much surveillance so I'm a little ignorant with some of these details. Customer wants doorbell cam "like Ring". Will install NVR for several other cameras in house. Wants the following:

View door remotely with iPhone.
Receive notification when doorbell is activated - allow talkback.
Add doorbell cam feed to unused channel on NVR.
Lock/unlock deadbolt remotely with app.
Wants above deadbolt to also have numeric keypad for keyless entry.

Does Ring or Doorbird(or other) meet all requirements?
Is there any NVR that should be considered or avoided to ensure it can be integrated?
Which deadbolt integrates best? What other interface is required for deadbolt control?

House is being gutted so any wiring requirements can be met. Thanks for any insight.
