Several months ago I posted about ftp problem with a PiZero, and it was
eventually solved by using a python script which was posted for me to use.
The said script worked well for a short while, until I stopped it
running for some reason.

Yesterday I booted up the PiZero, but it failed with some journal error
message. I copied the python script to my desktop before I re imaged the
sdcard, then copied the script back to the sdcard, insterted it into the
Pi and booted up.

After running the python script it failed with:
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 2] No such file or directory:
'//192.168.0.22/mnt/CCTV/PiZero/2018-06-06_17.26.37.h264'

Line 37 relates to
shutil.copyfile(RAMname, NASname)

I don't know about the shutil.py error and where it gets that old file
from which obviously doesn't exist

from picamera import PiCamera
import time
import os
import os.path
import shutil

from gpiozero import MotionSensor  #According to google motionsensor is
in gpio$

# Create object for PIR Sensor
# PIR Sensor is on GPIO-4 (Pin 7)
pir = MotionSensor(4)

# Create Object for Camera
camera = PiCamera()


while True:
     # Wait for motion being detected
     pir.wait_for_motion()
     triggerTime = time.time()

     #create base filename at time of motion trigger
     fname = time.strftime("%Y-%d-%d_%H.%M.%S.h264",
time.localtime(triggerTime))

     RAMname = os.path.join("/run/shm", fname)
     NASname = os.path.join("//192.168.0.22/mnt/CCTV/PiZero" , fname)

     camera.start_preview()

     #capture video to RAM device first
     camera.start_recording(RAMname)
     camera.wait_recording(10)
     camera.stop_recording()
     camera.stop_preview()

     #copy from RAM device to NAS device
     shutil.copyfile(RAMname, NASname)

     #delete file from RAM device
     os.unlink(RAMname)      #os.remove() is same function

     #set up next check time
     time.sleep((triggerTime + 30.0)
