I got notifications of birds chirping first thing in the morning, when the neighborhood was otherwise quite quiet, but I didn't get notifications throughout the day about every car that went by. For motion, the camera can record a clip of all the motion it sees, but the app lets you choose to be notified only of people. This is a great feature — I certainly don't want a push notification every time a car goes by — and it worked very well. I never got a notification of a person that wasn't actually a person. Then, you can just open the app to see a timeline of all motion events, not just people. The Nest Hello has some other cool features worth mentioning:Pre recorded responses: If you can't even be bothered to speak to the person at the door, you can tap the Responses button that appears in the Nest app and choose one of three recordings that will play out of the doorbell's speaker.
