Ok, I'll have a look at that.

Anyways, this is what I have tried so far

pi@raspberrypi:~ $ chown -R pi /mnt
pi@raspberrypi:~ $ chown -R pi /mnt/CCTV
pi@raspberrypi:~ $ chown -R pi /mnt/CCTV/PiZero

pi@raspberrypi:~ $ cd Downloads
pi@raspberrypi:~/Downloads $ python intruder.py
Traceback (most recent call last):
   File "intruder.py", line 37, in 
     shutil.copyfile(RAMname, NASname)
   File "/usr/lib/python2.7/shutil.py", line 83, in copyfile
     with open(dst, 'wb') as fdst:
IOError: [Errno 13] Permission denied:
'/mnt/CCTV/PiZero/2018-06-14_17.35.31.h264'

pi@raspberrypi:~ $ chown -R pi:pi /mnt/CCTV/PiZero
chown: changing ownership of
'/mnt/CCTV/PiZero/2018-06-14_17.35.31.h264': Operation not permitted



pi@raspberrypi:~ $ sudo chmod -R pi=pi /mnt
chmod: invalid mode: ‘pi=pi’
Try 'chmod --help' for more information.


I have been googling this permissions problem and have tried what you
see from what others have said.

The main problem I have is no matter what I try or do, the permissions
do not change for the /mnt directory. This is owner and group of root.

The other child folder permissons are owned  by pi, and group pi, so
unless I can get the permissions changed for /mnt, Ill never get my
project finished.
