Nest Hello lets you know who’s there, so you’ll never miss a thing. It replaces your existing wired doorbell, and delivers HD video and bright, crisp images, even at night. It’s designed to show you everything on your doorstep – people head to toe or parcels on the ground. And with 24/7 streaming, you can check in at any time. 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, then alert you. With Nest Aware, it can also let you know if it spots a stranger or someone you know. Say hello, even when you can’t. HD Talk and listen reduces ambient noise so that visitors come through loud and clear. And when you can’t answer, quick responses let you reply to visitors with different pre-recorded messages. 4:3 HD video designed to show people head to toe. The HDR video shows sharp details, even in bright and dark areas with a IPX4 rating. Your video stays safely in the cloud. We encrypt our connections. Keep data safe and private.
