I beleive that the reason that the color response is weird is that it has no
IR filter, which I took to my advantage by adding infrared LED's ( I work in
an area with limited lighting). If you don't like this, you can put an IR
filter behind the lens and in front of the CCD (the housing comes off).
WARNING: mark where the housing WAS with a marker FIRST!!! I think you can
get plastic ones at a camera store and cut them down.

I cannot explain your ghost image at all, other than your video cable may be
suspect. Also, the camera is marked for a 12V input, but they give you a 6V
AC adapter; I run mine from 12V.
