At 4.5 by 1.8 by 0.8 inches (HWD), the Ring Pro is slimmer and looks more like a traditional doorbell than the August Doorbell Cam Pro, the RemoBell, and the original Ring. It comes with four interchangeable faceplates (black, bronze, nickel, and white) to match the exterior of your home, a screwdriver, mounting screws and anchors, a Pro Power Kit for connecting to an existing chime box in case your existing doorbell wiring does not provide enough power, extension wires, and illustrated instructions. Ring also sells a battery-powered model, the Video Doorbell 2.

The picture isn’t quite as rosy if you’re also looking for a full-fledged smart home system. Ring Alarm is positively capable of being a great smart home controller. But it’s not that today. And to be fair, Ring isn’t promising that it ever will be—at least not officially. But they wouldn’t have built in Z-Wave, ZigBee, and whatever that third mystery radio is if they didn’t intend to go down that path.
Arming the system Away starts a 60-second countdown, delaying the armed state to give you time to exit the home without tripping any of the sensors. Opening a protected door while the system is armed also triggers a 60-second countdown, this one is to give you time to reach the keypad to disarm the system. If a sensor installed on a window is tripped while the system is armed, the alarm will go off instantly. That’s sensible: No one should be entering or leaving the home through a window while the system is armed.
Update 1/24/16 - I have found a fantastic use for the Ring Doorbell and Chime. My mother-in-law, now in her 90s, lives by herself. She has become hard-of-hearing and often does not hear the doorbell. By installing the Ring on her door, she now is bothered much less (solicitors tend to recognize it and don't seem to like it) and when someone rings the bell, the Chime, placed by her favorite chair, gives her a better chance of hearing someone at the door.
