HDMI to RJ45 Network Cable Extender (30M)

HDMI to RJ45 Network Cable Extender (30M) provides a practical way to transmit high‑definition HDMI audio and video signals over standard Ethernet cabling. This HDMI over Ethernet extender kit includes a transmitter and receiver pair designed to deliver synchronized 1080P video with zero perceptible latency. By converting HDMI signals for transmission through a single CAT5e/CAT6 network cable, this signal extension module simplifies long‑distance display connections while maintaining stable picture quality. Compatibility with computing platforms and media devices such as Raspberry Pi, LattePanda, PCs, HDTVs, and projectors makes this AV transmission solution suitable for development setups, presentations, and multimedia installations.

1080P High‑Definition HDMI Transmission

This HDMI signal extension module supports full HD 1080P video output, preserving image clarity across extended cable runs. A transmitter and receiver architecture converts HDMI signals into a format suitable for network cable transmission, enabling stable audio‑video synchronization without noticeable delay. Such design makes the HDMI‑over‑Ethernet adapter pair appropriate for media playback, digital signage, demonstration environments, and development workstations requiring reliable high‑definition display output.

Long‑Distance Transmission over Standard CAT Cable

This HDMI extender solution transfers digital video signals through a single CAT6 network cable, enabling extension distances from 1 meter up to approximately 30 meters depending on cable type. A TX transmitter converts HDMI output from a computer or controller, while an RX receiver restores the signal at the display side. Such Ethernet‑based transmission significantly reduces installation complexity compared with long HDMI cables and supports flexible routing across workspaces, classrooms, and equipment racks.
