For this HDMI extender, a single cat-5E/cat6 cable is enough instead of an HDMI cable, so the device can extend the 4K@30Hz signal up to a distance of 120 meters. PoC (Power over Cable) function is supported, that is, if the transmitter or the receiver receives an active power supply from a 12V/1A network adapter, the other device does not need a power supply. With a point-to-point connection designed to bridge long distances. The hdmi output on the transmitter unit provides a so-called (loop out) option, with which you can connect the signal source directly to the display by connecting an HDMI cable, so you can also place a display device at the beginning of the long distance and thus provide two displays at the same time. Features - HDMI 1.4/HDCP1.4 support; - Local loop-out support; - Signal transmission support up to 120 m away - Low consumption, low temperature and high level of security; - Transmitter (TX) and receiver (RX) support with 3.5mm left and right audio output; - IR control support; - POC support;
