The Gefen EXT-CAT5-5600HD is a sophisticated dual-display KVM extender system engineered to remotely operate a computer from a distance of up to 500 feet using standard Category 5e or higher cabling. This system transmits high-resolution video from two independent monitor outputs, along with full USB 2.0 peripheral connectivity and stereo audio, over a single twisted-pair cable. It is designed for mission-critical environments such as broadcast control rooms, security command centers, financial trading floors, and industrial settings where the computer hardware must be secured in a separate, controlled location while user access is provided from a clean, quiet, and ergonomic workstation. The system consists of a compact transmitter unit that connects locally to the computer's video, USB, and audio ports and a receiver unit that connects to the remote user's dual monitors, keyboard, mouse, and speakers.

A key technological feature is its ability to support extended dual-display configurations, including independent resolutions up to 1920x1200 per display, allowing for complex multi-monitor desktop environments to be fully replicated at the remote station. The system employs advanced digital video encoding and compression to fit the substantial bandwidth of two high-resolution video streams onto the network cable while maintaining visual fidelity and responsive, real-time control. The integrated USB hub functionality allows the remote user to not only operate the computer with a keyboard and mouse but also connect and use other peripherals like flash drives, printers, or hardware dongles as if they were directly plugged into the host PC, providing complete functional transparency.

The extender operates on a point-to-point basis and is typically powered from the receiver side via a standard power adapter, with power being sent over the same Cat5 cable to the transmitter, simplifying installation by eliminating the need for a local power outlet at the computer location. It is a hardware-based solution that requires no software drivers on the host computer, ensuring broad compatibility and enhanced security. By consolidating video, data, and control signals onto a single, affordable cable type, the EXT-CAT5-5600HD provides a robust, high-performance extension solution that dramatically increases installation flexibility, reduces clutter, and enhances operational security in professional and institutional settings.
