LG's DIY security device isn't a total novice

This is LG's $200 Smart Security Wireless Camera.

It has a built-in speaker and a microphone for two-way audio.

It also has a 93-decibel siren.

This 1080p live streaming camera will alert you if someone moves it.

It has an integrated Z-Wave hub so you can pair various Z-Wave devices.

This camera works with ADT's Canopy service, which delivers ADT's professional monitoring service and other features to products from other manufacturers on a month-to-month subscription basis.

You can also use the ADT Canopy Alexa Skill to control Z-Wave devices connected to your camera and say things like, "Alexa, record a video clip."
