third eye security

Hi guys, i am seeking some advise if possible. I have installed a 16ch DVR system. I have a monitor connected locally to the DVR but the site has a TV about 150m away. I have run a CAT5 cable and connected Baluns at each end. The problem im having is that the image on the TV is not stable. It flickers on and off and the picture quality is very very poor. On the TV side using a Balun i tried connected via bnc to scart, bnc to phono and cat5 to vga. All with the same results. I tried using 1 pair, 2 pair, 3 pair and 4 pair same result. I have tried replacing the baluns, same result. on the dvr side, if i plug 1 camera directly in the balun i get the 1 camera image on the TV. which indicates that the cable is fine. If i use a T BNC connector to split 1 camera feed i get the same problem as when connected to the video out for the DVR. So it seems when going via the DVR the picture gets distort. I am pulling my hair out now and i cant think what else it could be. Guys any help would be much appreciated. Thanking you in advance

SDM Group - not sure what you mean by check the termination on the DVR? can you change the output setting on the dvr?

The DVR only has 1 bnc output which it is connected to. yes baluns at both ends have the same colours going in to the same side left of the balun all strips right all colour. i have tried the scart input, vga input using a cat5 to vga converter and composite input the yellow 1. all have the same results. im running out of ideas on this...
