An intercom system is a communication device that allows people to talk to one another within a building or across different rooms without needing to move. It typically includes a speaker and microphone in each unit, with the ability to transmit voice messages. Intercom systems are commonly used in homes, offices, and apartment buildings to communicate between rooms, entrances, or floors. Some systems also have video capabilities, allowing users to see who is speaking. They provide a convenient way to communicate, especially in larger buildings or when immediate contact is needed.
