We are installing our first HD-CVI system indoors and it looks like the fluorescent lights are giving the image some subtle revolving lines. We ran all coax for these cameras through a drop ceiling, so I don't think the problem is coming from the wiring. There are quite a few lights in the area that where we are installing the cameras. Is anybody else having this issue?  It seems that the lines are less visible during playback.

Are any of the cables going over a Ballast? I have seen this with Analog cameras.

I have seen the issue before. Some cameras are more susceptible to them but it is the lights. The gas rolling through the tube is actually what is showing up. I am willing to bet if you turn the lights off or watch playback at night time you will not see the lines.

Try keeping any coax at least 3 feet from fixtures up there. Put some space between them and see if the pictures clear up.

It could be both interference from a ballast being that the cables are close to it as well as the fluorescent lamps like Daniel Mentioned.

Here is a video of how the fluorescent lamp looks. To the naked eye you will not see this unless the lamp is on its last days of life.

It looks like the monitor we were using was giving off the rolling lines. Thanks for the input though.
