Nest HelloInstead of the fisheye view you'd get from some doorbell cameras, Nest Hello combines a 160 degree field of view with a 4:3 aspect ratio. That gives you not only a wide angle view of the area around your front door, but a top to bottom view that lets you see the entire person approaching your door. It's also a handy view for spotting packages. Nest says the camera has HDR imaging for a clear picture, and there's a night vision feature, too. The camera doesn't just kick on when someone rings a doorbell. Motion sensors capture the image of anyone who approaches your door, and you're sent an alert on your phone. As with Nest Cam IQ, you can subscribe to Nest Aware to use the Familiar Faces feature and get continuous video storage. Out of the box, Nest Hello will capture three hours of snapshots from your front door and provide free person alerts. Nest Hello's app offers a head to toe view. Nest Hello features HD Talk and Listen so you can speak to whoever's outside. For those times when you're otherwise engaged, the Nest Hello app has a quick response feature, which plays a voice message.
