The Nest Doorbells give you a sharp, vivid view of your front doorstep. HDR helps you spot the details, rain or shine, while night vision helps you see in the dark. Use your phone or smart display to chat through the doorbell. Let a friend know that you're on your way, or tell a delivery person where to leave a package. Nest Doorbells have a 145° diagonal view. This means you can see people in full, and deliveries left on the ground stay within view. If you miss a notification, you can go back and see what happened. Nest Doorbells come with 3 hours of video history included. And if your Wi-Fi goes down, your doorbell will still record for one hour.
