X-10 Support: Camera audio quality

[kentcook]

X-10 Support and any wired camera owners

I have five wired camers - three Anaconda &
two Nightwatch.  I recenty decided to
connect the audio outputs.  None of the cams
produce anything but scratches, snaps,
clicks and pops with a loud hum.  I've tried
testing by connecting them individually to
my home theater amp with a phono y-adapter
and to my pc sound card with a phono to
stereo mini-phone adapter.  I get
irritatingly loud clicks hen switching the
camera on and off and no useable audio.  Are
all five cameras faulty or is the wired
camera audio feature really bad.  I've read
in other posts that some users get good
audio, but I think they have wireless cams.
