CCTV Video issues

["S. Smith" <ChaosLogicXIII@xxxxxxxxx>]

It's a big job... so we figured we'd do it right, but when everything
was plugged in, it was so wrong.

We ran everything in CAT5E and used passive baluns to make the
connections.  Funny thing, the longest runs went outside of the
building to "box cameras". They look great!  But the domes inside
suffer from all kinds of distortion.  Even the closest camera at a mere
30ft!  We're powering them all from a 12VDC Altronix power supply.

My first thought was interference caused by electrical cables or
flourecent lighting.  But the outside cams take the same path as the
domes without side effects.  This leads me to believe that there may be
a power issue.  I'm wondering if the dome cameras don't have the "umph"
to push the signal back to the DVR cleanly.  Suggestions?

Lastly, I'm looking for a portable meter to measure video strength but
I don't know what it's called to even begin searching.  Help?!

Thanks!
