SMAKN1 Pair 1080P VGA Signal 60M Extender Repeater Adapter Splitter Converter Single RJ45 CAT-5E/6 Ethernet Support 1080P Full 3D (1 Transmitter + 1 Receiver)

Using on 20m cat5e to display our security camera feed on a TV in the main office. Seems to work great thus far with a clear picture. At first I thought the ground was required as I was wiring it, but in the end, it seems to work without it. Not sure how this works on longer lengths, but it seems to be working fine for my applicationOnly thing I could draw as a negative is that it was lacking in documentation. Not a big deal as it was intuitive to set up and worked the first time, but i know i would have wanted some sort of documentation if it didn't work. quite right for some reason.
