DC auto iris lens cable? I replaced a CCTV camera recently that was
installed by another individual that is no longer with my company.
The older unit had an auto iris lens that was wired to a single pole
wall switch (there are no additional outlets or electrical devices
attached to this wall switch). The wall switch allowed me to disable
the power to the auto iris lens, but continue recording the audio in
the room and the on-screen text information (time and date). The
older lens unit only had a red, white, and silver wire with the red

(control +), yellow (drive +), and orange (drive -). I have no idea

previously mentioned. I would like to turn off the wall switch and
have the auto iris close, and turn on the switch to have the iris
