    Cameras fading in and out????

    I used an 18 camera 12DCV power box. Not sure of the mA's on it, but I've never had this same problem with any of the other systems I used the same power supply on. Not saying that it's not the problem, just haven't had the fading issue before. The one thing I did do different on this system is split the VGA monitor using a VGA splitter/transformer. The only difference I noticed in that was a slight decrease in resolution on both monitors. I'll be going to this job on Sunday afternoon and will first look at the connections and if the cameras have any settings on them for flicker. I don't remember any setting switches though. And if that doesn't work, I'll try replacing one of the cameras with a new one and see if that makes a difference. Thanks again for all the comments and suggestions....I really do appreciate it all.

    Soundy and Ted, thanks for the info. I used RG59 cable and twist-on ends (which if you use a wrench are a bit easier on the hands). I don't know of any grounding issues with 5 different lines, and all 16 of the cameras are run from one 12V power box. I will try to redo a few of the ends with crimp-on connectors and see if that makes a difference. I don't remember any flicker switches on the camera boards, but I'll check for those also. Thanks for the advice. I'll also try checking the cameras on my handheld test monitor and see if I still get flicker from the cameras. Funny part is this issue didn't arise until the cameras had been in service for about 2 months. Thanks again guys and I'll let ya know what I find.

    Cameras fading in and out????

    I'm at my wits end! I am fairly new to this whole thing and have been doing little side jobs here and there. I just installed 16 cameras in a store and I have a problem with 5 of them fading. Not to black, but just lighter and darker and changing color slightly. It's causing motion activation and eating up the hard drive....and it's just annoying and making my customers doubt my work. All the cameras are interior vari-focal dome type, and all are mounted @ 1-2 feet from fluorescent fixtures (cause issues?), and all are less then 100' runs using RG cable and twist on ends. Any ideas or recommendations on how I can fix this?
