Google Nest Hello Video Doorbell (10-Pack)

Nest Hello lets you know who’s there, so you never miss a visitor or a package. It can tell the difference between a person and a thing, then alert you even if someone doesn’t ring the bell. With a Nest Aware subscription, it can also tell you if it’s a person you know or a stranger. You’ll also hear everything loud and clear thanks to HD Talk and Listen, which even suppresses background noise and reduces echoes. Nest Hello requires an existing wired Door Bell and chime, as well as 16-Volt AC to 24-Volt AC power and a 10VA transformer.
