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. 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. If you don't want to attempt the installation yourself, the company can connect you with a Nest Pro. But if your existing doorbell's power supply is up to snuff, the process isn't terribly complicated. Facial RecognitionUnlike most video doorbells, the Nest Hello has facial recognition technology. Once you teach it the names of frequent visitors, the companion app available for both Android and iOS will start to name them in the push notifications.
