Hi Folks!
I think I have most of my problems solved, thanks to Roger and Mark for
their suggestions (and patience!). The cause of the problem seemed to be
multiple ? which doesn?t simplify troubleshooting.
First issued seemed to be with the wall wart. Replaced an approved
wallwart (5.1v @ 3,000 mA) with another approved wallwart (5.1 @ 3.0A ?
same ratings) and my gray glitchings mostly went away! I?m not ambitious
to check if the original power supply droops under load, though I do
have it marked to test later ? probably is fine except under a heavy
load of two USB cameras.
The other item seemed to be I was ?starving? the CPU of memory. With the
RPi4 it seems the graphics memory doesn?t need to be all that much. I
had set gpu_mem to 256 MB and had some glitching; reduced to the current
128 MB seemed to have eliminated the glitchings.
I had also reduced the framerate from 15 to 10 to finally 5. I?m not
sure if the framerate needs to be this low but for security-type
recordings/monitoring the outside seems adequate. I had also played with
framerate and memory settings sort of concurrently so my results are
intermixed.
And of course just as all was going well Summer hit and I lost the
cameras when the Storage Area (Attic) got warm. Measured ?on? the camera
104?F (non-contact thermometer?s red dot on one camera ? thanks to Roger
for reminding me of distance/more generalized reading detail!). I did
contact the seller/manufacturer and replied the operating temperature of
the camera is -20 to 70?C (-4 to 158?F). Hmmmm: both of mine don?t seem
to like much over 100.
Roger suggested white tape to reflect heat; I?m not so sure that?s going
to work here. Going to Rube Goldberg things a bit and try Peltier
Junctions on the back panels (cameras are in a metal case). Probably end
up with pictures of frost! <g> If that doesn?t work will have to either
move the cameras to a cooler location or try some rated for high heat
conditions.
Barry

I have to agree with Jack. The config of motion is so easy and it's
dependencies are so trivial that there is no decent technical reason to
isolate it into its own vm.
I have used my KVM guests to do my taxes and it is only up once in while,
no reason to keep it up.

Just use a Raspberry Pi.
It's a $35 solution and can run 24/7 using a minimal amount of electricity.
