4-wire video intercom indoor monitors are communication devices designed for secure and clear video and audio interaction within buildings, using a dedicated four-wire connection for power, video, and audio signals. This wiring method separates the transmission paths to enhance signal quality and reduce interference, making these monitors ideal for medium to large residential complexes, commercial buildings, and multi-tenant facilities.
Equipped with high-resolution displays and two-way audio capabilities, 4-wire video intercom indoor monitors enable occupants to see and communicate with visitors before granting access. They often include features like door release control, call history, volume adjustment, and easy user interfaces. The separate wiring provides stable performance and compatibility with a wide range of intercom systems, ensuring reliable security and communication throughout the property.
