This HDMI® over dual CAT5 extender transmits your HDMI A/V signal with IR to a remote location up to 30 m (100 ft.) away over dual CAT5/CAT6 cables.

Control Your Video Source from the Remote Display

With IR extension built-in this HDMI transmitter and receiver kit offers remote infrared extension, enabling you to control your video source from the remote display, ensuring you can always see what you’re doing, even from a distance.

Crystal-clear 1080p Video

This HDMI extender maintains your 1080p picture quality, ensuring your remote picture is crystal clear. The extender also supports 7.1 audio for optimum sound quality.
