 If you actually implemented what I was describing, the camera file
should be created directly on the NAS via the mount point, and you do not
want to try copying or deleting what results.]

 Which sounds like it is creating the file entry in the directory, but
not copying data... But, again, if you made the changes I suggested, there
is no file in "RAMname" to be copied, and the file in "NASname" should
already exist (I don't know if copyfile() can replace an existing file).

 If the mount command worked, then "/mnt/CCTV/Pizero" (is that correct
-- Linux is case sensitive and in other places you use "PiZero"?) and the
NAS "PiZero" ARE THE SAME PHYSICAL DIRECTORY; any change in one should
appear in the other. At worst you might have to refresh any directory
display to see the changes (if you are using a GUI or web interface to view
the NAS).
