As part of a security system, the unit can help protect your home by detecting motion outside. The Nest Hello has plenty of fun and functional features, like “Quiet Time” that disables the doorbell function and only send a message through the app that someone is at your door. Another cool feature is pre programmed responses you can use called “Quick Response. ” Quick Response allows you to choose from built in responses to address people you know, or people you don’t know if you aren’t home or don’t want to be disturbed. Another reason Nest is the best doorbell camera is because of “Familiar Faces,” which recognized people who the camera has seen before. Once you mark them as known, the Nest Hello will let you know via text the name of the person when they arrive.

6 x 1. 7 x 1 inches, and has rounded corners. On its face is a round doorbell button lit by a blue ring, with the camera above it. Image credit: NestIts small size leaves no room for onboard power, which means the Nest Hello requires a wired connection with 16 to 24 volts of power. That power requirement can be an issue for older houses — I previously had to get the transformer on my 1946 built bungalow upgraded to get a Ring Pro doorbell with the same power requirements to work. The Ring Video Doorbell 2 and the August Doorbell Cam Pro run on batteries, which makes them easier to install.
