Thanks to the Ring Chime, you can hear it throughout your home when someone rings your Ring doorbell. You plug the Chime into a socket. Without the Chime, you only receive a notification on your smartphone. With this doorbell, you'll know when someone is at the door even if you don't have a phone nearby. Via the Ring app, you can easily connect this device to all Ring doorbells and Ring security cameras. When a camera detects movement, the Chime provides a signal. As a result, you're always aware of activity in the rooms you've secured with a camera. A Ring doorbell needs a strong WiFi connection near the door. Is that an issue? Choose the Chime Pro, as it's a WiFi extender as well.
