Update 3/24/16 - Ring has added “Live View” to their feature set. It allows you to access your Ring Doorbell any time you wish. This solves the problem with #3 as long as you are not on battery power. Obviously, it also lets you “dial in” any time you wish to check out your front or back yard (where ever your doorbell is). This is a feature that I like as every once in a while I just like to see if its raining or foggy at the house.
Getting this much capable home security hardware for $199 is an absolute bargain (the system became available for purchase today). Adding door/window sensors for $20 each and motion sensors for $30 is an absolute bargain. Paying $10 a month for professional monitoring and video storage in the cloud for an unlimited number of Ring security cameras is an absolute bargain. Ring Alarm will be a huge hit with people looking for a straightforward, easy-to-use home security system.
Ring’s motion sensors and contact sensors are much more traditional than Nest’s, which cleverly combine the two into a single device that also adds a nightlight. Nest’s base station also combines the keypad with it and adds even more motion detection sensors – Ring’s separate base station and keypad approach is almost clumsy in comparison. But it is possible to add multiple keypads to the Ring system, so you can have one at each entry way or in your bedroom if that’s a more convenient place for it. The keypad can be placed flat on a table or mounted to the wall, and uses a simple MicroUSB cable for power. Its internal battery lasts between six and twelve months, according to Ring, so it’s possible to install it in a location that doesn’t have an accessible power outlet and just charge it occasionally.
The other thing of note is its lack of smart home partners. Despite being owned by Amazon, Ring's system doesn't work with Alexa or any other major smart home platforms. If you want to arm and otherwise get the status of your home security system via voice commands, the Ring Alarm Security Kit isn't the right option for you. Ring does specify in its support section that it's working on these integrations for a future release.
So this Ring Video Doorbell worked for about 4 months. I came home one day and the door bell button was stuck in the down position and the unit burned out. I contacted Ring and customer service was receptive and sent me a replacement unit. Unfortunately the replacement unit had trouble connecting to my solid wi-fi and I was directed to reboot the unit by holding down the orange button for 20 seconds. After the unit was rebooted it connected to wi-fi but would not charge or ring my mechanical door chime. My unit was hardwired to my doorbell using a 16 volt transformer and mechanical door bell and the first unit worked fine until it burned out. I spent some time on chat with customer service going through all the troubleshooting when they eventually agreed to send another replacement unit.
