  1. Hi there, I have an 8 channel IQ CCTV brand DVR. I have standard irish 'netopia' router. Having issues setting up remote access over the web for the dvr. I can get it working on local network, accessible by anything using the same router. Has anyone done this and can help me?

    CCTV ghosting problem

    Thanks for the reponses. Ran a cat5 cable across the ground today and sure enough it solved the problem! Twisted pairs ftw!

    CCTV ghosting problem

    Thanks guys. The 10 pair cable is buried underground so I really dont want to have to dig it up! Would doubling up wires cut down on crosstalk or would it just weaken the signal? Could it be related the a PSU problem? I have checked the power supply and its giving 12v properly on all wires and is more than rated for the job, amperage wise.

    CCTV ghosting problem

    As far as i can see wires are all straight within the plastic insulation. (not twisted or paired). There are 10 white wires and 10 other colors. By split pairs do you mean broken/damaged pairs?
  5. 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.
