Replace your existing wired doorbell with the Google Nest Hello Video Doorbell, the doorbell you’ve been waiting for. It’s designed to show you everything at your doorstep, people head to toe or packages on the ground and with 24/7 streaming, you can check in anytime, or go back and look at a 3-hour snapshot history to see what happened. Nest Hello can tell the difference between a person and a thing, and then alert you, even if a visitor doesn’t ring the bell. With Nest Aware, it can also let you know if it spots a stranger or someone you know. HD Talk and Listen reduces ambient noise so visitors come through loud and clear. And when you can’t answer, quick responses let you reply to visitors with different pre-recorded messages.
