Nest's new home security system aims to combine power with ease of use

[sincity]

Nest is taking home security to the next level with Nest Secure, a new alarm system that protects your abode with a hands-off approach that's just as effective at protecting against intruders. 

There are multiple components to the system, which Nest unveiled at an event in San Francisco, starting with Nest Guard. 

This is the brains of the operation, and acts as the alarm and keypad as well as a motion sensor. Shaped like a hockey puck and smaller than the Amazon Echo Dot, you tap your Nest Tag (which we'll get to in a bit) to arm and disarm the system. 

Guard will also utter a countdown clock of how much time you have to leave the house once you've armed it.

Nest Tag and Nest Guard

Then there's Nest Detect. This battery-powered motion detector is placed on the wall and will sense when doors or windows are open, and picks up movement in rooms (both when it's on a door). You can tap a button on Detect to disarm a door if, say, Fido needs to go outside.

The aforementioned Nest Tag is a little tile that can attach to your key chain. It allows you to arm and disarm your security system without needing to input a passcode. Just walk in the front door and touch your Tag to the Nest Guard.

Nest Detect

You can control the entire system from the Nest app, arming and disarming your alarm wherever you are and receiving alerts if something is detected. There's also an option to bypass the alarm through a featured called Quiet Open

It's all designed so you actually use it, rather than be turned off by complicated and intrusive systems that don't fit with the average person's lifestyle.

As for price, a Nest Secure starter pack costs $499 (about £370 / AU$620). This includes one Nest Guard, two Nest Detects and two Nest Tags. 

You can add on additional components as well, with each Nest Detect costing $59 (about £45/ AU$75) and additional Tags priced at $25 (about £20 / AU$30). Best Buy will also sell a package for $598.

The Nest Secure system is launching in the US this November, with availability in more countries coming next year.

New Nest IQ

Nest also introduced a new Nest IQ outdoor camera at its event today. 

The camera is weatherproof, Nest says, and uses facial recognition as well as motion detection to sense who's there. 

Nest also unveiled a smart doorbell, called Nest Hello. It too uses facial recognition to tell who's come a'knockin', can record in HDR, and has a night-vision mode. 

• Nest Cam IQ will soon feature Google Assistant
