--Get alerts that matter to you. The Nest Doorbell lets you see what’s happening at your door and answer it from anywhere. It knows the difference between a person, package, vehicle, and animal, and alerts you when there’s activity, so there’s no guessing. It can even recognize familiar faces and tell you who’s coming and going.

--Go back in time. If you miss a notification or other event, you can go back and see a recording of what happened over the last 3 hours with free event video history.

--See who’s there, even when you’re not.  A taller field of view and HDR let you see people clearly from head to toe,  and packages on the ground. If you miss something, 3 hours of free event video history lets you  go back and see what happened with the Google Home app.

--Designed for any door.  The Nest Doorbell is battery powered and wire-free, so it works with any door, whether you live in a house or an apartment. You can install it yourself. And it comes in a range of colors to make any doorstep more stylish.

--Protects your privacy. The Nest Doorbell uses encrypted video, two-step verification, and enhanced security through your Google Account to help protect your privacy. And a green LED light lets you know when the camera is processing or streaming video.
