Amazon Echo can now make a noise like a dog barking if you're not home — here's how to set it up - CNBC

Among other things, your Amazon Echo can make it sound like a dog is barking inside your house if your security cameras sense movement when you're not home.

Guard Plus can also alert you to any sounds in your home using your Amazon Echo and sound a siren if activity is detected inside.
