The VigilLink VLIP-VGH1G-ENC is part of a 4K UHD multi-function extension system that allows you to extend an HDMI signal along with KVM using the TCP/IP protocol over regular Cat.5e/6/7 network cable. This extender supports the transmission of Ultra High-Definition signals (up to 4K@30Hz RGB) with audio and USB up to 328 feet (100m) over a single cable. The transmission distance can be further extended (up to 328ft per segment) by using gigabit network switches, allowing the user to cascade the system without signal loss or introducing delay. When the extension system's units are in multicast mode, a single transmitter’s AV signal can be sent to a large number of receivers within the same local network (unicast limits extension routing to point-to-point only). Additionally, that same multicast signal can be used to create large multidisplay video walls with amazing simplicity. When combined with the optional IP Master Controller, the functionality of the system expands exponentially. Its centralized web-based interface greatly simplifies control and management of large distributed video matrix or video wall systems, adding to their flexibility in large home or commercial installations. This system also features bi-directional IR and RS-232 pass-through, analog line level in/out, and a microphone input (on the receiver), providing the user with a variety of audio options. The USB functionality allows the system to act like a remote USB hub, which provides a flexible remote KVM platform. Configuration information is provided via On Screen Display (OSD), and control is by WebGUI, IP Master Controller, Telnet, and front panel controls.
