OREI 4K HDMI over Ethernet Extender Over CAT5/CAT6/CAT7, with IR Upto 164 Feet - Loop Out - 4K @ 30Hz 1080P Full HD Signal Distribution (EX-170C)

Bought so I can run my POE cameras on 2 screens, one in a back office and one in the store. Works as advertised, had to use cat5e cable to run since the HDMI wire was a bit bulky and most likely would need a repeater to carry the signal all the way. This box elimated the repeater and the POE aspect of it makes it super simple and no extra plugs. The video quality seems to be great this far on my main screen, although my other TV is only 1080p I bought this 4k so I could upgrade the TV later and not have to worry about buying another product. Would recommend have had it running for a few days now and no complaints.

Great product, did exactly as it should. No special thing, just plug and play.

These things are great, easy to use and does what it says.....

Best HDMI extender I have used yet. I have 4 different HDMI Extenders, and this one was the coolest. It only requires power at the TX side. And it comes with an IR extender which is great for an LCD projector. I mix audio for corporate events and the LCD projector is often not accessible to me so the IR extender is a must have. This is also more compact than others. The power connector threads on so there's no risk it will get unplugged. Would definitely get this again if I needed to replace the other ones in my rig.

First time ever using one of these and after a little trial and error it works well! Using it so we can see the camera DVR in another room while we are watching tv. So yeah, it does work for a security camera DVR/NVR.

Works well. Sometime when yo unplug from the source and connect it back, no signal will be displayed. Works 90% of the time.

I bought this product to extend the HDMI signal from my Apple TV in front of the room to my Projector in the back of the room. The installation was very easy and the instructions were clear. The product works as advertised and delivers a crisp and clear picture and sound quality. I like the loop out feature that allows me to connect another monitor near the transmitter. The IR feature is also handy to control the laptop from the TV room. The only downside is that the product is a bit pricey, but I think it is worth it for the quality and performance. I would recommend this product to anyone who needs a reliable HDMI extender over Ethernet.

The OREI EX-170C is not actually sending Ethernet frames. It is using the copper pairs inside Cat5/6/7 cable as a point-to-point transport for HDMI signals. The manufacturer calls it “over Ethernet” only because it uses the same type of cabling and connectors, not because it speaks Ethernet or IP.This will not work through an Ethernet switch or anything that expects actual Ethernet frames. You will need to look at a different model that also includes the word "IP". This is ridiculous as Ethernet doesn't require IP to link to MAC addresses. However, it is now obvious that this device is merely a direct transmitter-to-receiver link. The devices on each end expect to be electrically connected over the twisted pairs.A switch, instead of passing along the proprietary signal, drops it because it doesn’t look like valid Ethernet traffic.If you want an HDMI extender that does work over a switch, you need one that explicitly supports IP transport (sometimes called “HDMI over IP” or “AV over IP”). Those encoders wrap the HDMI signal into real Ethernet/IP packets, which a switch can forward.This particular unit is more like an “HDMI balun” than an AV-over-ETHERNET device.
