Doorbell technology

There's been a lack of decent door bell systems to choose from. Finally there a simple solution for those who want to know who is calling. Ring is a standalone system which allows the homeowner to view who is calling directly from camera built into the doorbell. It's possible to speak to whoever is at the door are well... whether you are home or not. This is great if you've got a delivery or unwanted visitor. It can be paired up with other ring cameras to allow full 360% surveillance of the property. Its great... although as a stand alone system we'd want to see if it can be tied into other features around the home. It would be great, for example, to see this tied in to a smart lock so you could unlock your front door too.
