rkolb86 0 Posted November 30, 2011 Is it run parallel to a/c for any long distance? Share this post Link to post Share on other sites
rkolb86 0 Posted December 1, 2011 I could just be settings (video format or something else), could be the baluns, could be the cat5 to the camera. I'm no camera expert, but I don know structured wiring. You shouldn't run that cat5 parallel to a/c within 12 inches for any more than a few feet. This could be the problem.

indboonies 0 Posted December 2, 2011 Try powering the camera locally at the building it is hanging on. If the power wire goes all the way back to your shop you could be having uncommon grounding issues with the buildings. I have run into that in the past and powering locally to the building has cleared it up. Share this post Link to post Share on other sites

rkolb86 0 Posted December 6, 2011 Did you determine that electrical interference was the issue? If the electrical interference is the issue, I doubt PVC will do anything to fix that. The metal (steel?) electrical conduit might do it, but that is a shot in the dark as well. Also, using shielded twisted pair (instead of UTP) may also help resolve the issue.

tomcctv 189 Posted December 6, 2011 will running the camera wires in pvc conduit stop electrical interferance in cctv videos i have run cat 5 for camera wire 650 foot from our shop to the main building .the picture is good at the source and am using a powered utp thats 200m power down cat 5. under powered cameras can give the same effect as electrical interferance. are you running 12 or 24v what amps and what camera are you using Share this post Link to post Share on other sites
