VEDINDUST 4K30Hz HDMI Extender Over 131FT Transmitter and Receiver Over Cat5e/6/7 RJ45 HDMI Ethernet Adapter Support 4K 1080P HD 3D POC EDID

picture quality on these is ruined by Digital artifact pixelation. i tested them at 100m of CAT7 Cable the sound was good with no audio delay. but the picture was covered in Digital pixelation. i don't need them to work at this distance. i only need them to work at 30f so i tested them at this distance also with the same result. it's not the cable or connections to blame as I'm using CAT7 Shielded cable. and my other sender receivers i own for another part of the house can easily send the same signal from my Blu Ray player much further. even longer distances up to 120m without any issues. my other set cost more they are HDbaseT also can go by HDbitT. if your looking for good quality senders and receivers forget about these and purchase ones that are HDbaseT or HDbitT units. they will cost more but you'll be getting what you pay for. "you won't regret it". these ones however are not recommended. *update* i returned these 4k units for a full refund. then seller contacted me and sent me a replacement free of charge of the "HDMI Extender 1080p version" and these ones work perfectly with no issues. no Digital pixelation and perfect sound. Excellent seller. recommended

I buy these time and time again, they’re brilliant. Replaced very old ones with these and haven’t let me down.

I bought this with aa 30M CAT7 cable. About every 20 minutes the picture was lost at the RX end. If i removed power and then re-enabled power after about 5 seconds the picture was restored. Twice in a 40 minute stretch the picture crazed but recovered quickly My feeling, and it is only that, 30M is probably the max length you want to use, and then expect problems, I think you would do better to be thinking in the region of 20M perhaps 25M, but I have not tried these lengths. NOTE: I ran the ethernet away from any electrical interference and it was unravelled to its full extent. PS - The seller offered a refund due to the problems I experienced with the HDMI extender. This was very good of them, and suggests to me that the seller is trustworthy, and cares about their product and customers. I am leaving the review basically the same, just changing from 3 stars to 4 stars, but purely because of the seller.

I installed these in a car garage for a stand alone cctv camera they worked really well, I think the cable length between the camera and monitor was 40m and it works perfectly, recommended

Stopped working after a few months very light use unable to find a way to return waste of money also never worked at stated range had to make shorter runs on the Ethernet and find a shorter path requiring a lot more work to make it work at all.

Worked well

I'm using this to send an HDMI signal over a 7.5m CAT7 cable into a capture card, and it works flawlessly. Was sceptical because of the low price but the unit functions without any issues, easy to set up, and comes with mounting brackets if you want to secure it down.

Good product around 60 MTRS but definitely don't work within maximum distance as I found out to my suprise perfect product as I say around 60 MTRS had to send back and get a replacement.however this is still a sturdy product and good picture
