Design and InstallationThe Nest Hello video doorbell is sleek and slim, at 4. 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.
