I have 2 active vision active baluns that I can't get to display the video from my everfocus ptz. I can get two active vision passive baluns to display the video (though not as crisp) so I know it's not the video wire, power to the ptz, or anything outside the balun. I am pretty sure it has to do with the grounding of the balun, which I have tried a few ways also. I get the power light to come on, but the video light comes on sporadically, mostly never. What is the proper way to wire an active balun?

Thanks

I believe your distance at least be 1.2km apart, could be theres a break in the cat5 cable. Maybe if you have spare pair you may want to try connect and see if the power source still Intermittent.

I would be using a TDR to check the lines

I don't believe there is anything wrong with the cat5, as I get a picture using passive baluns at 1000'. I believe it has something to do with the grounding, will it not pick up the video without proper grounding?

Thanks
