The OREI KVM 4K HDMI Over Ethernet Extender Balun is designed to transmit high-definition video and USB signals over long distances using standard Cat6 or Cat7 cables. Supporting resolutions up to 4K at 60Hz, this unit reliably extends HDMI signals up to 230 feet while maintaining crisp picture clarity and smooth motion. The extender features two USB 1.1 ports, allowing keyboard and mouse connectivity at the remote location for convenient control of a connected source device.

An integrated HDMI loop-out port enables local monitoring while simultaneously sending the signal to a distant display. Power is delivered over the cable (PoC), meaning only one power adapter is needed at the transmitter side, simplifying installation and reducing clutter. Constructed with a durable metal housing, the extender balances heat dissipation and physical protection, suitable for both residential and commercial environments.

The unit is plug-and-play, requiring no additional software or drivers for basic operation. It supports 4K@60Hz 4:4:4 color depth, ensuring vivid color reproduction for presentations, digital signage, or home theater setups. Compatibility with Cat6 and Cat7 cables ensures future-proofing for existing network infrastructure.

From a technical perspective, the extender operates reliably at distances up to 230 feet, with stable signal transmission that minimizes latency and frame loss. The USB 1.1 interface is optimized for keyboard and mouse input, providing responsive control for applications such as remote workstations, security camera monitoring, or classroom teaching. The device also includes built-in surge protection to safeguard connected equipment.

In terms of usability, the compact form factor fits easily behind a desk or mounted on a wall, and the LED indicators provide quick status checks for power, link, and video signal. The extender is an affordable solution for extending KVM (keyboard, video, mouse) functionality without the cost and complexity of dedicated digital signage equipment. Its balance of performance and value makes it a practical choice for offices, schools, or home offices requiring reliable long-distance HDMI extension with USB pass-through.
