With the introduction of these six new products, Nest doubles its hardware portfolio for the second time in a year.

Nest Secure alarm system is a home security system designed for ease of use. The Nest Secure starter pack includes:

Nest Guard, an all-in-one security base that provides the alarm, keypad and a motion sensor, and a voice.

Nest Detect is being marketed as a category first: a sensor that detects both motion and open or close movement in one compact, battery-powered product. Put it on a window and it will know when it opens. Stick it on a wall and it senses motion in a room. Place it on a door and it can do both.

Nest Tag is a convenient fob that can attach to a keychain, allowing you to easily arm and disarm Nest Secure without a passcode.

Nest Hello video doorbell and Nest Cam IQ outdoor security camera, a purpose-built outdoor security camera that protects homes with best-in-class imaging and intelligence, and tamper resistant, weatherproof components.

"Today, Nest is delivering on the next phase of our strategy to create the thoughtful home," said Marwan Fawaz, chief executive officer of Nest. “We’ve had quite a year so far, expanding into 11 more countries, growing our product portfolio with the successful launches of Nest Cam IQ indoor and the Nest Thermostat E, and today we’re disrupting yet another product industry: home security. By building product experiences our customers love, Nest has experienced more than 60% growth on devices shipped in recent years and continues to expand to millions of homes around the world.”
