The ST121UTPHD2 HDMI® over Cat5 Extender Kit can extend the audio and video signal output from an HDMI®-equipped device by up to 330 feet (100 Meters), over a single CAT5 cable, or up to 165 Feet (50 Meters) over a single CAT6 cable. The extender supports full High-Definition video (4K and 1080p) and HD 3D, and also extends the accompanying digital audio signal.

For convenient, time-saving control of the media source, the CAT5 HDMI extender offers bi-directional RS232 serial and Infrared (IR) interfaces, which enable you to control the HDMI audio-video source from either end of the connection.

To help ensure seamless performance without any unexpected or unnecessary interruptions, the HDMI Ethernet transmitter and receiver units are fully compliant with High Speed HDMI® and HDCP standards, and each unit features lockable power connectors to prevent accidental disconnections.
