Perfect companion to the Ring Video Doorbell. Sometimes I put my phone on silent and don’t hear if someone is at the door. With the chime, we hear a pleasing chime alerting us we have a visitor at the door. You can also set it to give you motion alerts too, but I prefer just to see motion on my phone and have the chime go off when someone is at the door. It’s your choice though and it’s great that it offers you the choice.

• Plug Ring Chime into any standard power outlet, and get instant alerts anywhere in your home.
• Plug and play: Plug it in, connect it to your Wi-Fi network and link it to your Ring devices. It’s that easy.
• Compatible with Ring Video Doorbell, Ring Pro and Stick Up Cam.
