The Ring Video Doorbell 2 and the August Doorbell Cam Pro run on batteries, which makes them easier to install. In addition, Nest requires you to install a small module called the "chime connector" inside your doorbell's chime box, located inside the home. Installation isn't difficult, but it is another step. Nest includes everything you need to attach the doorbell to your house, even a huge drill bit in case you have to drill into stucco siding.
