    @tomcctv: I used what was advertized as HD-TVI baluns (has screw-in terminals you slide the wire in)

     

    Don't know if I am allowed to post links, but it is:

    or

    I used generic 1080p TVI domes, since I am doing a 15-camera setup for about 49 a piece. Happy with the image quality so far. The Cat6 is solid copper, thinking that in the future I won't have to run cables for IP camera upgrades. I ordered the ferrules from cable and ferrule gleaned from a post in this forum somewhere.

     

    thanks

    Hello all,

     

    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?

     

    thanks

    richard
