The Nest Hello video doorbell and the Nest x Yale smart lock are finally available for sale beginning today on Nest's online store, but not on Amazon.
Nest's Hello, a $229 (roughly £165/AU$290 converted) hardwired buzzer with a built-in 1080p high-definition camera, first debuted in September 2017.
Like the Nest Cam IQ Outdoor and the Nest Cam IQ Indoor, the Hello has free livestreaming, motion detection and person alerts.
The doorbell's camera can also scan faces from a database you create in the Nest app -- and actually tell you if a friend or family member is at the front door.
Facial recognition requires a subscription to the Nest Aware cloud recording service, which starts at $5 per month.
