A new guy @CCTV. I've searched and read a lot of the posts here, and have either missed or not finding an answer.
I purchased a Hik DSQ 16ch DVR. Ran cat6 UTP, terminated with baluns (ferrules at camera ends & DVR ends). PS is a 10amp transformer. Cameras are generic 12VDC HD-TVI 1080p ones. So far, I put 7 cameras on the PS.
I am getting these vertical rainbow colored bars, about 3/4 inch wide; that scrolled from left or right (not all channels scrolled in the same direction).
Made sure that the cables are away from house wirings. I went as far as moving the cat6 around/jiggled and re-cutting the ends and re-crimped with new ferrules.
These bars appeared only during the day. IR at night is fine, although it may be that it's not as obvious in B&W.
What is odd is one camera is doing fine. The other 6 are showing these bars in varying severity.
Any hints on what to look for?
