    Hi all,

    Installed a system for a family member consisting of 3 cameras in an outside shed for watching animals calving etc. However, I am getting very bad interference problems that I can not seem to fix. First time working with cameras so any help would be greatly appreciated!

    So the system has 3 cameras. (2 dome IR and 1 bodied). These are inside 2 sheds and wired back to a central box using RG59 shotgun cable. (Carrying video and 12v power).

    Inside this box I have connected the 12v and crimped BNC plugs onto the RG59 cable. I have connected these BNC plugs into standard cat5 baluns and wired into a 10pair external cable that runs 80m to the house.

    Inside the house I have put baluns onto the cable and attached into DVR.

    On the monitor inside when viewing any camera I can see the images from the other cameras strobing across the screen. Looking online I can see what is refereed to as crossbleed or ghosting.

    Hope the picture below makes sense.

    Sounds like a cable or psu problem to me. 10 pair poly doesnt have the same level of twist as cat 5 which leaves it open to interference
