When someone presses the button or device outside the door, the signal triggers the chime or bell to sound, signaling to the person inside that someone is at the door. Door buzzers are commonly used in residential and commercial buildings as a simple and effective means of communication between visitors and occupants.

With advancements in technology, door buzzers can now also be connected to video intercom systems for added security.
