Thanks for the above code, and when I run it , it returns this, when
movement is detected,:

Traceback (most recent call last)
  File "intruder_recmotion.py",  line 37, in 
   shutil.copyfile(RAMname, NASname)
  File "/usr/lib/python 2.7/shutil.py", line 83, in copyfile with
open(dst, 'wb') as fdst:
IOError: [Errno 2] No such file or directory:
'/192.168.0.22/mnt/CCTV/PiZero/2018-16-16_11.25.36.h264'

I have checked the path to the PiZero folder or dataset on my FreeNAS
box and it is correct.

Thanks again
