intercom system
Two-way voice link
An intercom system is a network of audio or video devices allowing communication between different rooms or areas within a building.
Offices, apartment buildings, and homes use intercom systems so people can speak without physically meeting: The receptionist buzzed me in through the intercom system.
Modern versions may include video screens and remote door controls.
