I cannot say enough about this item. Sorry I am limited to only 5 stars. * * * * * Here I will give it another 5 Worked right out of the box after setting the co/cpe switches. I have been trying to run security cameras 600 ft from the dvr with poor success. I tried 'balun' connectors but got waving pictures.
I put the 'co' unit behind my router and used cat5 cable that was in place, although I think it will work with almost any copper pair. 600 ft down the line I put the 'cpe' unit and connected to the dvr. Immediate success! There is so much you can do with this. You can add a bridge to extend your network or a router to create a new separate network.
Wish I would have come across this last year before wasting time and money. It's a little pricey, but well worth it and cheaper than others on the market. I could go on forever, I am so pleased with this.
