Google's Nest launches smart burglar alarm that can identify intruders

The company hasn't yet announced a price or release date

Google is packing its facial recognition and other tools into perhaps the smartest burglar alarm ever made.

Home device maker nest – which is owned by Google's parent company, Alphabet – build upon the company's smart thermostat and smoke alarms in an attempt to revive the troubled brand. The company has been selling much the same products since it started six years ago, but has finally rolled out a new suite of security products intended to keep people's home safe.

The central feature of the new alarm system is that it can recognise its owners but spot intruders, allowing it to smartly watch over the house.

Although Nest has been among the early leaders in the effort to make home appliances as intelligent as people's smartphones, it hasn't been able to make money to the frustration of its corporate parent, Alphabet. In an attempt to shake things up, Alphabet brought in cable industry veteran Marwan Fawaz to replace Nest founder Tony Fadell as CEO after Fadell stepped down 15 months ago.

Nest had been supplementing its existing product line with slightly different choices until Wednesday's move into entirely new categories.

The 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 upon Google's facial recognition technology so it can warn a home's occupants when a stranger approaches. Google bought Nest for $3.2 billion in 2014 and then spun it off after it hatched Alphabet as its parent company.

Nest is now lumped into a group of risky companies venturing into new areas of technology that have collectively lost $10.6 billion during the past three-and-half years alone. Alphabet hasn't disclosed how much Nest has contributed to it the losses in its "Other Bets" segment.

Nest isn't announcing a price for its new doorbell until it hits the market sometime during the first three months of next year.

Google's facial recognition technology is coming to the doorbell a few months after Nest introduced a more sophisticated indoor security camera featuring the same tool. Nest also announced Wednesday that the same facial recognition tools will be deployed on an outdoor security camera that will cost $349.

Apple is implanting a different form of facial recognition into its $1,000 iPhone X to unlock the device, telegraphing a future where cameras increasingly are going to be able to identify people within its lens' range. The new phone will be released in November.

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.

The Nest home security system is being billed as a simpler and more convenient way to protect a home than the alarms and other kinds of sensors that have long been sold by other vendors. Nest's "Secure" system will sell for $499 for its basic toolkit of devices.
