In the era of smart homes, secure offices, and connected living, door intercom Market Size have evolved far beyond simple buzzers. Today, they serve as a critical layer of access control, enabling two-way communication, video verification, and integration with mobile apps or home automation platforms. Whether installed in residential buildings, corporate offices, or gated communities, door intercoms improve both security and convenience.

What is a Door Intercom System?

A door intercom system is an electronic communication solution that allows audio or video interaction between visitors at a building’s entrance and residents or security personnel inside. It enables individuals to screen visitors before granting entry—manually or automatically—via a button press, smartphone, or connected security system.

Key Components:

• Outdoor Unit (Door Station): Includes microphone, speaker, camera (for video models), call button, and sometimes a keypad or RFID reader

• Indoor Unit (Monitor Panel): Enables the resident to see, hear, and talk to visitors; may also unlock the door

• Control Hub/Power Supply: Manages signals and power distribution

• Mobile App or Cloud Access (in smart systems): Allows remote communication and access control
