Controls a media player from up to 130 ft. away and extends 4K HDMI video, USB and IR signals that same distance (230 ft. for 1080p). This extender kit includes a transmitter (local unit) and a receiver (remote unit) that work in tandem to extend and distribute HDMI audio/video, USB and IR (infrared) remote signals. Using Cat6 cabling (sold separately), the B013-HU-4K transmits 1080p video from a computer, Blu-ray player or other media center to an HDMI display or interactive whiteboard located up to 230 feet away. By connecting a keyboard and mouse to the receiver’s dual USB ports, you can also control the source device from that same distance.
