Older door bell

A doorbell is a device which is typically installed to or near a door. When a visitor presses a button, the bell rings inside the building, alerting the presence of the visitor.

History

Older doorbells were fully mechanical. Newer electrical doorbells were installed by wires and use a push-button to activate the sound. The latest doorbells have wireless connections.
