1. What is an Indoor Intercom System and How Does It Work?

An indoor intercom system is a communication device that allows people within a building to communicate with each other or with individuals at a building’s entrance. Commonly used in homes, apartment complexes, offices, and commercial facilities, these systems offer enhanced security, convenience, and internal communication.

How Indoor Intercom Systems Work

Indoor intercom systems are typically composed of:

• Master Unit: Installed in a central place, usually the entrance or reception area.
• Sub Units: Installed in rooms or individual apartments.
• Door Entry Panel: Installed at the main entrance, often with a camera.
• Power Supply & Wiring: Powers the system and connects units (for wired versions).
• Wireless Connectivity: For wireless or IP-based intercoms, using Wi-Fi or LAN.

The primary functionality includes:

• Audio communication (full-duplex or half-duplex)
• Video monitoring (camera-based systems)
• Door unlocking remotely
• Broadcasting or paging to multiple rooms

Residential	Room-to-room communication, front door video access
