A 2 wire video intercom system is an intelligent security device that combines video surveillance with two-way voice communication. It is widely used in residential buildings, gated communities, offices, hospitals, and schools to manage visitor access and enhance safety.
The system’s defining feature is its use of just two communication wires for both power and data transmission, ensuring reliable performance and simplified installation.
A typical 2-wire video intercom includes the following components:
A 2-wire video intercom system uses just two wires to transmit both power and digital audio/video signals. It upgrades old analog systems to HD IP video intercoms without the need for new wiring. Here’s how it works:
Call Initiation: The visitor presses the call button on the outdoor unit. The camera takes a live photo, and the system turns this into digital data.
Signal Transmission: The digital signal travels through the two wires to the indoor monitor, alerting the resident that someone is at the door.
Trudian’s two-wire video door intercom system uses existing wiring and modern digital technology to provide HD video calls, remote access, and smart home integration, all with low upgrade costs. Unlike traditional 4-wire or full rewiring solutions, it’s faster to install and more cost-effective. Digital signal transmission ensures stable performance and clear video quality. The system also supports remote door unlocking and works with popular smart home and security platforms, making it ideal for both homes and businesses.

Superior Video Quality: Equipped with 1080p or higher-resolution cameras, the two wire intercom system supports wide dynamic range (WDR) and night vision, ensuring clear visuals day and night.
User-Friendly Operation: Featuring a multilingual interface, the indoor monitor allows users to take photos, record videos, adjust volume, answer calls, hang up, and unlock doors remotely. A complete access log is automatically generated for easy tracking and security audits.
