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 Ring Alarm system has three different modes, which can be set via the keypad or through the iOS and Android apps. There’s the standard disarmed mode that turns off all of the monitoring; an away mode that watches all of the installed sensors for intrusions; and then a “Home” mode, which by default will monitor sensors installed on entryways, but ignores motion inside the house. I’ve used the latter mode as basically a night or sleep setting, since during the day my family moves in and out of the house a lot and would constantly trip the door sensors.
3 - If you do not answer the alert fast enough, you are locked out-- even though someone is standing at your front door. You cannot "turn on" the camera from your phone or tablet. If someone is there and you do not have an "ACCEPT" button on the screen, there is just no way to see or talk to them. This is obviously a software flaw. You should always be able to "wake" a camera remotely and talk to a person at your front door. Or maybe you just want to see the view outside your front door. You should be able to access the camera / microphone and enjoy your front yard.
