Problem with video quality over Cat6

Recommended Posts

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 ?

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) ?

Thanks vector18, that did the trick nicely - see result

 

Hi Sir,

 

Can you please post the isolator picture and advice the model that you used.

Thanks
