Thanks for your advices, it was quite easy to setup the ftp using your instructions, I also created a new user and setup the user home directory inside /var/www/html/security_camera_storage.  The camera is saving new images each time there is motion, my only problem so far is how other users can access those images? 
 
I tried to create a php script to scan the directory where images are saved but it seems it fails as the directory is owned by user securitycam, and php is running with a different user. I want to setup some cronjobs to scan and delete old files (let's say, I will delete every image older than 3 days), I will also need to display the images in my dashboard, so I will definitely need to find a fix to this "issue"
 
The other files in html folder are owned by admin user.
 
Any advices on how to setup the ftp to save files that can be accessed by admin user, are welcome
 
Thank you.
 
UPDATE
 
I have added user admin to group secuirtycam, but still didn't help:
 
sudo usermod -a -G securitycam admin
sudo chgrp -R securitycam /var/www/html/security_camera_storage
 
After seeing that PHP still can't access that folder, I changed the permissions of that folder to 777. Is this such a bad thing? even if this bananaPi is a local device, obody else has access to this pi, just me.
 
sudo chmod -R 777 /var/www/html/security_camera_storage
 
This way it scans the folder, but unfortunately newly added files, are still not accessible, the main folder is accessible, PHP script is seeing all the files, even the new ones, but when I try to display them in a webpage, the images are not shown. So I still need to fix this, the proper way
 
Thank you.
