Motioneye Privacy Mask for Weather Underground

Weather Underground PWS IPENNANT2

 

 

Create a motion mask using Motioneye tool as needed for the purpose of camera view privacy

Copy the created file (mask_1.pgm) with a new file name (privacy_mask.pgm) as -

              cp /data/etc/mask_1.pgm /home/ftp/sdcard/privacy_mask.pgm

Then add this line to video device Extra Motion Options as -

              mask_privacy /home/ftp/sdcard/privacy_mask.pgm

 

 

 

 

 

Setting up my webserver using Motioneye on a Raspberry Pi Zero W

 

I installed the MotionEyeOS complete system image using the tutorial by Julian Silver as per the link below

https://randomnerdtutorials.com/cctv-raspberry-pi-based-system-storage-motioneyeos/

of particular use was the instruction at section 2 -

"2. Installing MotionEyeOS on the RPi Zero W boards"

This points to the base MotionEyeOS image applicable to the Pi Zero W - "raspberrypi-xxxxxxxx.img.gz".

Of particular note is the important step of creating the Wpa_supplicant.conf file to set the country code "AU in my case" and the wireless network credentials.

Having setup my system and connected the camera, I then configured the ftp to upload images to my Weather underground PWS site. That is address webcam.wunderground.com port 21 and location /.

So the next step was to create a privacy mask so as not to indrude on any of my neibours in the camera field of view. Even though the camera has a very wide angle lens and the upload image is not high resolution I felt it important to black out any sections of the image that might captured the neighbours backgarden.

So to create the privacy mask

I read a description on github that suggested using the motion mask for this purpose. See-

https://github.com/ccrisan/motioneyeos/issues/1910

Sounded easy, but for a relative novice like me it took a while to implement.

So in motioneye under motion detection I switched on Mask

Then chose Mask type editable

and selected "Edit Mask"

I then tagged the squares in the image at locations I wanted to screen and pressed save.

I then initiated an SSH connection to my Pi and logged in. Then used the command line to perform the tasks required.

After much reading and testing I found the newly created motion mask at file location -

/data/etc/  with file name mask_1.pgm

I then copied this file with a new file name (privacy_mask.pgm) to the preferred location for the privacy mask

cp /data/etc/mask_1.pgm /home/ftp/sdcard/privacy_mask.pgm

Then entered the suggested line to video device Extra Motion Options

 

mask_privacy /home/ftp/sdcard/privacy_mask.pgm

 

In this way I created my desired privacy mask in Motioneye to be add to all my snap shot pictures before upload to Weather underground.

 

Usefull commands that I used in Raspberry Pi -

find / -name *.pgm - to find the initial mask file in the first instance when I did not know its location

cp - to copy file with new file name

cd /data/etc/ - Change to the required directory to view the motion mask file

cd /home/ftp/sdcard/ - Change to the required directory to view the privacy mask file

find / -name privacy_mask.pgm - to find my newly created privacy mask file to check it was in the desired location

ls list files

ls -l list files and attributes to check the latest version

rm deletes files

fdisk --l viewing hard disk partitions
