I have a 4K POE security system. I just bought a state of the art 4k camera to add to my camera system. I had to run it further than the 60 foot Poe cables that came with the system. This cable was much easier to pull through the wall since it's flat. I wanted to use the full potential of the picture quality so I bought this cable and it didn't disappoint. The camera I connected it to worked straight away when powered by this cable and the image quality on it is incredible. This Ethernet cable easily handles massive data transfer speeds. The file size of 4K videos is very large and you definitely don't want to compromise with cheap cables. I highly recommend this cable!
