18Gbps 4K60 HDMI over HDBaseT Extender Kit with PoC - 40m 4K / 70m 1080p
Power Both Ends from One Adaptor - 4K60 4:4:4 10-bit HDR, HDCP 2.2, Bi-Directional IR & RS-232 over a Single CAT6

Delivers 4K60 4:4:4 HDR from the rack or lectern to a display or projector up to 40 m (131 ft) away, with power needed at only one end of the run. The kit is a compact black metal transmitter and receiver, each 4.53 x 2.56 x 0.67 in (115 x 65 x 17 mm), linked by a single straight-through CAT6 cable that also carries 1080p to 70 m (230 ft). One 24V/1A adaptor plugged into either unit powers both over the cable, so a ceiling projector or a display above a fireplace needs no outlet. It is the right choice for classrooms, meeting rooms, hospitality venues and residential media rooms where a clean single-display run with full 18Gbps video and control matters more than eARC, USB or Ethernet extension.
The link is HDMI 2.0b at 18Gbps with HDCP 2.2 and 1.4. It passes 10-bit HDR and HBR audio, including Dolby TrueHD, DTS-HD Master Audio, Dolby Atmos and DTS:X, with CEC bypass. Two independent IR channels and bi-directional RS-232 on 3-pin Phoenix connectors share the same cable. A control system at the rack can drive the display, and a handheld remote at the display can still operate the source. Two IR emitter cables and two IR receiver cables are in the box, so both directions work out of the box. Nothing touches the network, so there is no IP addressing to plan and no IT sign-off to wait for. Link and HDCP status lamps on both units show at a glance whether the cable run or the source is the problem. The single strongest differentiator is Power over Cable from either end: the adaptor goes wherever the outlet is, at the source or at the display.
