🏠 What is a 2-Way Intercom System and How Does It Work?

A 2-way intercom system is a communication solution that allows real-time audio (and sometimes video) transmission between two or more points within a building or property. In residential settings, these systems are often used for entry communication, room-to-room talking, or gate control.

Key Components of a 2-Way Intercom System:

Component	Function
Indoor Monitor	Installed inside the house; receives calls and allows two-way talk
Outdoor Intercom Unit	Near gates or doors; has call button, microphone, camera (if video)
Power Supply	Typically wired or PoE; some wireless models use batteries
Communication Protocol	Wired analog/digital or wireless (WiFi, DECT, RF)
Optional Accessories	Remote unlock relays, doorbell chimes, integration modules

How It Works:

1. A visitor presses the button on the outdoor unit.
2. The indoor monitor rings and displays video (if applicable).
3. The homeowner communicates with the visitor via the microphone/speaker.
4. Optionally, the user can unlock the door or gate remotely.

Types of Home Intercom Systems:

• Audio-only intercoms – Basic, cost-effective, used for simple voice communication.
• Video intercoms – Include a built-in camera for visual verification.
• Wireless systems – Easy to install, ideal for retrofitting.
• Wired systems – Higher reliability, ideal for new constructions or larger homes.
