The downside of a wireless Ring Doorbell is that you need to charge the batteries now and then. But it's almost as easy as charging your phone or laptop.

If you see a white light flashing on the right, that means the doorbell is having problems connecting to the Ring Temporary Access Point, a temporary wireless connection used during the setup process.

Ring brings its 3D motion detection and Bird’s Eye View features to its most powerful battery-powered video doorbell, and it expects to fetch a pretty price for it.
