DDMALL HE-20

These look quite cheap and unlikely to do the job but the opposite is true.Just completed a large CCTV installation and needed to send two separate streams to two separate TVs. Each TV was to show just a single camera out of a 22 camera setup.I used good quality CAT 6 cable and the cable run was probably 40 to 50 meters.One TV cable needed two couplers and the other a single coupler.These devices connect directly into the HDMI port of the CCTV recorder and into the TV. Making sure you have the transmitter in the recorder and the receiver in the TV, all you need do is connect the CAT 6 cable, choose your TV input source and off you go.Very simple setup and very good and quick results.It’s worth noting that I had tried a different product that required a power source and had a button you could press to determine cable length and best signal but they didn’t work well at all and the picture flickered and was very unstable.I will use these Devices again.

Worked without any problems, just plug and play. Used to have sky q box mounted remotely. Full HD was transmitted without any problems, highly recommend.

Generally worked ok but the fitting at one end is very loose and needs to be lodged in place to get the connection. Once this is done it works effectively.

I used this to mount my PS4 in a network cabinet across the room and then send the signal to the monitor.It sends the sound and video just as if it were a real cable.It's a great product.

More information about setting up, with the usb connecting to the receiver end first, would be good.Also the size of the units can not be used on a close fitting TV bracket with no side connections.Other than that the units worked perfectly ovd a Cat5e cable over 60m long.

I had 2 hdmi cables embedded into the wall ceiling and down the opposite wall to the tv. Both cables stopped working after 3 years. This solution worked perfectly with the cat5e cable - picture and sound is crystal clear.

I do not usually do reviews but this HDMI extender is excellent and gives excellent picture on a 7inch monitor some 10 metres from the source. It is being used to monitor a CCTV system. I did not consider cheaper versions after reading other reviews. A great bit of kit.

Excellent this thing jus works connected transmitter to my receiver then cat 6 cable to the receiver the other part of this device into my projector no long lengths of hdmi well happy thanks 👍🏻
