Ring Doorbell is a Wi-Fi enabled doorbell that allows you to see and speak with visitors at your door, from anywhere. Each doorbell is equipped with an HD camera (720P) with night vision and smart motion detection. Even better is that it works with ADT Pulse. You can see it in your ADT Pulse App. And if you use the Ring app you can use that to also control your ADT system and ADT Pulse Deadbolt. The Ring Pro new 1080p version is also available for only $50 more and is smaller but requires hardwired power.
When someone walks in front of the doorbell or pushes the button it will alert you and let you see and talk to them from anywhere. If you want to have the video clips recorded you will need to set up a subscription with Ring that is only $3/mo or $30/year.
The Ring Doorbell works with ADT Pulse, but you are not able to see live video from the camera whenever you want. Only when there is motion or someone pushes the doorbell. The motion option also lets you set up zones.( see image below of motion zones)
You can install it to replace your existing doorbell (and use the two wires that are there) or you can install it in addition to the existing doorbell. It is a quick and relatively easy install. It comes with a rechargeable battery that lasts around 3-6 months. ( I just took mine off and charged it for most of the day and the original charge lasted 10 weeks. We'll see 10 weeks from now if I am in the same boat or better)
It comes in 4 different colors.
