Overview
Orei builds this as a transmitter and two receiver set that moves one HDMI signal onto Cat6 network cable and back out to two displays at once. The transmitter also carries a local HDMI output, so a monitor beside the source stays wired directly. Power over cable runs voltage down the same cable, and an IR kit brings remote commands from the receiver end back to the source.
Reaching two screens in separate rooms usually means long HDMI runs or a second source, and this kit avoids both by putting the signal on Cat6. Resolution and distance trade against each other, so the longest runs only hold the lower formats. Everything is plug and play, with no software to install.
Who it's for
Rooms where one player or computer has to reach screens in two places, such as a bar with a second TV across the floor or a conference space with a display in the hall. The receivers need their own power path over the cable, so plain patch cables and a distant outlet will not do. Anyone wanting wireless casting or a matrix that routes different sources to different screens should look elsewhere.
Pros and cons
- Splits one source to two displays at once
- Local HDMI loop out on the transmitter
- Receivers draw power over the cable
- IR passback controls the source remotely
- Cat6 cable not included
- 4K limited to 30Hz
- Shielded Cat6 recommended for the run
- IR kit range not listed
Performance notes
Distance and resolution pull against each other: the link holds the higher format over shorter runs and drops to the lower format as the cable gets longer. Shielded Cat6 is recommended because the signal rides the cable rather than a wireless band, so cable quality and terminations decide whether the picture stays clean. Power over cable removes the need for an outlet at each receiver, which leaves the far end simple.

Frequently asked questions
How do I maintain the Orei HD12-EX165-K over time?
Leave the transmitter and receivers where air moves around them, and check the Cat6 terminations if the picture ever drops, since the signal rides the cable rather than a wireless band. Keep the IR emitters aimed at the source and the receiver eyes where a remote can see them. The kit carries a one year manufacturer warranty and lifetime tech support.
What comes in the Orei HD12-EX165-K box?
One sender unit, two receiver units, a user manual, a power adapter and the IR kit.
Can the Orei HD12-EX165-K feed a local monitor as well as the two remote displays?
Yes. The transmitter has an HDMI loop out alongside its two Cat6 outputs, so a monitor beside the source stays wired directly while the receivers serve the distant screens.
Does the Orei HD12-EX165-K need power at each receiver?
No. Power over cable sends voltage down the Cat6 run from the transmitter, so the receivers do not need their own adapters.
What cable should I run for the Orei HD12-EX165-K?
Cat6 or Cat7 ethernet cable, with shielded Cat6 recommended because the HDMI signal travels over the cable and cable quality shapes the result.
