Now the new one is their Nest Hello, a video doorbell that's basically a nest cam for your front door or back door that's the answer to the popular ring doorbell. It looks nice and compact and will be available in 2018 with no pricing just yet. Now Nest also introduced their own modular home security system called Nest Secure, with a central hub called the Nest Guard. And a variety of sensors, and even a tag that can arm or disarm the system as you come and go. Now the starter pack costs $499 and ships in November. Plus there's a new Nest Thermostat E, that has most of the functionality of the current line, but comes in a more affordable $169 package with a frosted plastic design.

San Francisco, CA — September 20, 2017 — Nest Labs, Inc. (nest.com), architect of the thoughtful home, today announced a home security solution that includes the Nest Secure alarm system, Nest Hello video doorbell, Nest Cam IQ outdoor security camera, and corresponding software and services.

• Nest Secure alarm system – A home security system designed to be tough on intruders and easy on you. The Nest Secure starter pack includes these products:

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

• • Nest Detect is 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 Tags are easy to share with family members and trusted people who regularly enter the home, like dog walkers.

• Nest Hello video doorbell – Nest’s first video doorbell combines the trusted security and intelligence of a Nest Cam with the familiar convenience of a doorbell.

• Nest Cam IQ outdoor security camera – Purpose-built outdoor security camera that protects homes with best-in-class imaging and intelligence, and tamper resistant, weatherproof components.
