Amazon is rolling out a new feature for its Echo smart speaker devices called Alexa Guard. Alexa Guard turns your Echo into a mini-home security device. It will listen out for noises like smoke alarms going off or smashed glass, and send alerts to your phone including audio clips and a video feed (if your Echo has a camera).
Following a beta test last year, the feature will soon be available to all Echo owners in the United States. You can start using it by enabling Guard in the Alexa app.
