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. You can also set an automatic notification when that person arrives. The Nest Hello’s simple design utilizes your existing doorbell wiring, so you won’t have to worry about replacing batteries. The body of the unit is made of plastic and, while the exact dimensions haven’t been released, does look smaller than other products on the market. The Nest Hello has a 160 degree HD camera that has night vision capabilities and HDR imaging. When you open the app, the live view is front and center, and is crystal clear during the day and at night. One issue other products have is the limited range of the camera, but the Nest Hello allows you to see people approaching from head to toe, so there won’t be any questions about who came within view of the Hello. The doorbell is secured to your house via a metal base, so you don’t have to worry about anyone stealing your Nest Hello from your home.
