Knock! Knock!: The Ring Video Doorbell gives you one-way video and two-way audio so you can see and talk to who's at your door.

It's as easy as connecting the camera to a power source with the included USB cable and USB AC power supply. Then turn on the app and when the camera is ready it will read a barcode off the app, which will set it up on your existing WiFi network.
