The Google Nest Doorbell (Battery) is a smart video doorbell that lets you see, hear, and speak to visitors from anywhere using your smartphone — even when you're not home. It detects and identifies people, packages, animals, and vehicles, sending tailored alerts so you know exactly what's happening at your door. With 960p HDR video, a head-to-toe wide field of view, and night vision, it captures the full picture of every visitor. Battery-powered installation requires no wiring, making it easy to fit on any door or gate without an electrician.
