The Evolution of Doorbells: From Traditional to Smart and Beyond

A doorbell is a device that alerts you when someone is at your door. It typically consists of a button or switch on the outside of your home, and a bell or buzzer inside your home to signal that someone is at the door. Some doorbells also have additional features such as a camera or a speaker, allowing you to see and communicate with the person at the door from your phone or another device.
