Product Description
The Dahua HDMI Cable 20 Meter 4K is designed for extended-distance transmission of high-definition digital audio and video signals between HDMI-enabled devices such as TVs, monitors, laptops, gaming consoles, projectors, and DVR/NVR systems.
It supports 4K Ultra HD resolution, delivering sharp image quality, rich colors, and smooth video performance for both home entertainment and professional applications. The cable is engineered to maintain signal stability over long distances, helping reduce degradation commonly seen in standard copper HDMI cables at higher lengths.
The 20-meter length is ideal for large-scale installations such as conference halls, auditoriums, control rooms, and CCTV monitoring systems where devices are placed far apart. It is built with shielding to minimize electromagnetic interference and ensure consistent signal transmission.
For long HDMI runs like 20 meters, performance may depend on cable quality and installation environment, so professional-grade shielding and construction are essential for stable 4K output.
