Ground Loop challenges

[ABLE1 <someone@xxxxxxxxxxx>]

Hey Guys!!

I have a camera install that is plagued with Ground Loop issues.

I have been installing individual BNC Ground Loop Insulators on
individual cameras that are the worst which cleans up the video for that
camera.

However, over time another camera gets bad, and then another, etc.

As I understand the problem is due to an imbalance in voltage at 60
cycles or ground reference between phases from the power company. And
that the video is very sensitive to the imbalance and causes the video
bars, bla bla bla.

My questions are as follows.

Is there a something device thingie that can be installed at the breaker
panel across the phases that can blend or sync the cycles, etc.??

Is there a something device thingie that has more than one individual
port that can be mounted at the head end (like a 8 or 16 port) that can
isolate the ground loop with out using all the dongles??

Thanks for any insight!!
