Nest's newest security camera will take facial recognition to another level, with better sensors and software smart enough to detect the difference between family members, pets and potential intruders in the home.

The new $299 Nest Cam IQ is using AI algorithms that recognize familiar faces. The camera has an 8-megapixel image sensor and 12x digital zoom. That allows users, with a companion app, to zoom in on faces. With a $10-a-month Nest Aware subscription, they can enter their names, and the next time a person appears on camera, a smartphone alert will identify them.

The new hardware is an improvement from the camera's predecessor, Nest Cam Indoor, which has a 3-megapixel sensor and 8x digital zoom.

The camera will only identify people you select through Nest's app for iPhones and Android devices. For instance, you could program the device to recognize a child, friend or neighbor, after which it will send you a notifications about that person being in the home. It won't try to recognize anyone that an owner hasn't tagged.

Google purchased Nest for $3.2 billion in 2014, but in 2015, Google's founders renamed the parent company Alphabet and set up Google and Nest as separate divisions.

Nest said users can place orders for the Nest Cam IQ starting Wednesday. The cameras will ship a month from now and be sold in 11 countries, including the U.S.
