OREI4K HDMI over Ethernet Extender Over CAT5/CAT6/CAT7, with IR Upto 164 Feet - Loop Out - 4K @ 30Hz 1080P Full HD Signal Distribution (EX-170C)

Good extender, but beware that is a bit finicky with the type of cable you use.In my case i can run perfectly fine up to 10m (32ft) with cat5e/6 and tested it up to 20m (64ft) with cat7 in a ceiling with power lines, balun lights fixtures and AC ducts. Both cases with a good certified crimp.Also they don't have noticeable lag, and more importantly for my use case, the lag if any is the same for multiple units so you can use it for video walls.Cons are that they don't like bad DIY first time crimping RJ45 works. Also over 10m (32ft) i didn't have much luck if each pair is not shielded in electrically noisy enviroments.

Works perfectly as advertised. I managed to daisy-chain two of these together (HDMI output from one into HDMI input of the other) and was able to get security camera footage sent to two different offices across a 100ft CAT6 link. HDMI output from DVR into input of the first transmitter, and then the transmitter's HDMI output into the second transmitter's input. Great unit, highly recommend.

In its price point - it's the absolute best quality. Entirely plug and play - many churches I support with A/V stuff bought the cheap ones...they all now have these. They work. They just work with NO problems or issues.

Excellent products work as installed no problem at all, the price is also very reasonable. Good purchase!

Works pretty well, but not necessarily high-end unit

This works great. Using it with a 100ft cat5 cable from a sound booth to stage at a church hall.

Product worked right out of the box with not extra setup other than plugging everything in.

It works
