following:

>pi@raspberrypi:/mnt $ sudo chown -R 777 /mnt/CCTV

 Unless you have a user named "777" those parameters are wrong.
http://www.linfo.org/chown.html
"""
 The basic syntax for using chown to change owners is

    chown [options] new_owner object(s)
"""


>drwxr-xr-x 3 777 root 4096 Jun  5 09:50 CCTV
              ^^^ ^^^^

^^^ user name
^^^^ group name

 Try

chown -R pi /mnt/CCTV

 Or (untried) create a new group (call it NASuser), chown the mount
point to that group, and then add pi user to the new group.


 That 777 looks like you are trying to set permission levels (the rwx
stuff you see on the left). That command is chmod

chmod/
