LNK-4KH-FL is a video extension device that can transmit high-definition audio and video signals over a single network cable (or fiber optic cable) at long distances, and can simultaneously transmit one high-definition signal in both directions.

This product supports one local loop-out of the video signal, supports RS232 serial port, supports OSD function, supports independent audio input and output; it has the characteristics of long transmission distance, low usage cost, convenient installation, good compatibility, and is a stable and efficient transmission product. This product adopts a pure network system architecture and combines a modular design concept, not only has the advantage of stable and efficient hardware architecture, but also can support various interface and business module combinations, meeting different application scenarios, and the transmission distance between each node is not limited.

Designed for the application needs of intelligent, full-function control and command centers, it is suitable for energy and power, judicial and prison, smart cities, government services, water conservancy and hydrology, meteorology and seismology, enterprise management, metallurgy and steel, banking and finance, transportation, exhibition and display, production scheduling, broadcasting and television, education and scientific research and other fields. This product focuses on long-distance transmission control but is not limited to transmission control, and is a new solution for modern control centers.

Interoperability

►     The platform can seamlessly connect and interoperate with various front-end devices, without any restrictions on the network operators.

►     Through TCP/IP networks, the platform can collect audio, video, and sensor data from front-end devices without requiring fixed IP addresses, and display real-time control management through visualization.

Multiple signal outputs

►     The platform can simultaneously output to various display terminals (such as LCD panels, monitors, LED matrix screens, advertising screens, projectors, etc.)

l Audio processing

►     Support HDMI audio input and output and independent audio input and output.

l Signal switching

►     Integrated audio and video matrix function

►     Multiple signal sources can be merged into a grid and displayed in equal parts on a single window, or a single signal can be displayed full-screen.

Multi-system compatibility

►     To ensure system stability, the core of the system uses an embedded Linux solution.

High-definition access

►     Remote signals can be captured and displayed on the wall through the network, and the signal processing is free of ghosting, distortion, and lag. The lag cannot exceed 0.2 seconds.

►     Each large screen display wall should be able to share, select, and display any input signal.

Signal display

►    The output signal is processed in real-time at 4K@30Hz resolution, without any frame rate reduction internally, to ensure clear and smooth output images, high color fidelity, and compatibility with input and output customization, meeting the true point-to-point requirements.
