tdenson 0 Posted February 6, 2013 I am using a pair of video/Cat5 converter boxes (passive) over a run of about 60 metres of Cat6. The attached image shows the picture quality. I am getting a horizontal white bar that moves from bottom to top, also generally waviness of the image. Is this more likely to be some interference or my connections ? Also, as a subsidiary question, I have a telephone cable (3 twisted pairs) running over the same route carrying an RS485 signal for PTZ - can I use one of the pairs of this with Baluns in the same way as CAT5/6 ? https://dl.dropbox.com/u/2351913/Church/photo.PNG Share this post Link to post Share on other sites
vector18 1 Posted February 6, 2013 Can you get your hands on a balun with a built in ground loop isolator? Share this post Link to post Share on other sites
tdenson 0 Posted February 6, 2013 Can you get your hands on a balun with a built in ground loop isolator? Just bought one off eBay, seems a handy thing to have anyway. I assume I only need one (just at one end) ? Share this post Link to post Share on other sites
