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 Nest site. The Nest Doorbell works with other Nest products. Hear announcements on Nest Mini when someone is at the door. And Nest Hub will show you who’s there when someone rings the bell. If you miss a notification, go back over the last 3 hours with free event video history. If you want more, add Nest Aware Plus for up to 60 days of event video history. The Nest Doorbell (battery) does not record 24/7 video history, even with the optional wired installation. 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. Wire-free means installation is painless. You can put it at the vantage point that works best for your door. See key details in all kinds of light. HDR helps with bright, high-contrast sunlight, and night vision gives you a clear image even in low light and darkness.
