 Which is the same permission error that the shutil.copyfile() was
producing. This tells me that there is nothing wrong with the script
itself. The problem appears to be on the NAS side -- since it IS accepting
operations that provide a file name, but then refuses to accept the actual
file data.

 Restore the script to the version using RAMname for the capture, and
with the .copyfile() back in place. When it dies do the following and
cut&paste the results into a message:

ls -l /run/shm

cp /run/shm/*.h264 /mnt/CCTV/PiZero

rm -f /run/shm/*.h264

{Note: the last line is going to clean out old files from /run/shm -- cp &
rm together produce the effect of

mv -f /run/shm/*.h264 /mnt/CCTV/PiZero
}
