Home-device maker Nest Labs is adding Google's facial-recognition technology to a camera-equipped doorbell and rolling out a security system in an attempt to end its history of losses.
Nest's Hello doorbell comes with a built-in video camera and speakers that will make it seem like it can recognize and talk to people.
The doorbell will draw on Google's facial recognition technology, so it can warn a home's occupants when a stranger approaches.
Nest's usage of facial recognition hasn't yet sparked privacy concerns because it doesn't tap into Google's vast database of photos to automatically recognize people. Instead, a user of the Nest camera or doorbell must manually tag and name people before the device recognizes someone.
