SAN FRANCISCO (AP) — Nest's new home security camera is supposed to be so smart that it can identify people it's been introduced to. That skill comes from facial-recognition technology made by Nest's sibling company, Google. The Nest Cam IQ camera is so slick that it carries a premium price — $300 — plus a $10 monthly subscription to run the facial-recognition program and other features, such as 10-day video storage.
