The Dahua VTNC1003C 2-Wire Video Door Station Controller simplifies the integration of intercom systems in modern residential and commercial installations, enabling direct connection to cameras and indoor units via standard two-wire cabling. Its compact design supports proprietary Dahua protocols for stable transmission of HD video, two-way audio and access control, ideal for multi-family or office buildings where secure remote monitoring is required. Equipped with interference-resistant interfaces, it ensures clear signal up to 100 metres without additional amplifiers, optimising installations without complex cabling.

Advanced Control Functionality

This controller manages up to 4 indoor units simultaneously with functions such as remote lock opening, real-time video call and event detection for push notifications on compatible mobile apps. Upgradable firmware incorporates AES encryption to protect communications against unauthorised access, while RS485 ports allow expansion to wider control systems such as alarms or home automation. Configurable programming via Dahua ConfigTool software adjusts parameters such as microphone sensitivity and image brightness to suit varying lighting environments.

Practical Installation and Compatibility

With small dimensions of 110x80x25 mm and surface or flush mounting, it facilitates deployments in outdoor panels exposed to the elements (IP65). Supports PoE or 12V DC power with low power consumption of 3W, integrating seamlessly into existing IP networks for remote viewing from kindergartens, car parks or vehicular access. Compatible with Dahua VTO series such as the 4th generation, this 2-wire module offers scalability for professional security projects without service interruptions.
