• Control with the Google Home app. View live HD video, replay video recordings, talk to visitors, and more – all from the Google Home app. The Nest Doorbell (battery) requires a free Google Account and is not compatible with the Nest app or the home.nest.com site.
• 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.(1) It can even recognize familiar faces (2) 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. If you want more video history, you can add a Nest Aware Plus subscription for up to 60 days of event video history. (3) The Nest Doorbell (battery) does not record 24/7 video history, even with the optional wired installation. Learn more about the differences between event video history and 24/7 video history at g.co/nest/videohistory. The Nest Doorbell (wired), formerly known as Nest Hello, and other Nest cameras can record continuous video with a Nest Aware Plus subscription.(2)
• 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.(1)
• 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.
