Raspberry Pi Camera sends Pictures to ownCloud

Of course, there are many variants to take pictures with your raspberry pi camera and save them somewhere.

I use my raspberry pi camera to observe my flat when I am away. I want to do this in a as secure way as possible, i.e., I do not want to open any special ports on my router nor do I want to send unencrypted images over the web.

Inspired by  http://blog.davidsingleton.org/raspberry-pi-webcam-a-gentle-intro-to-crontab/  my idea was to take a photo every 5 or 10 minutes and save them to my ownCloud server via WebDAV with SSL encryption.

Step by step:

1.) Make sure you have a raspberry pi with a camera module and an owncloud installation reachable over https  somewhere out in the web (with picture app activated).

2.) Mount your owncloud drive on your raspberry pi: Create the directory /home/pi/owncloud  and add the following line to fstab:

https://[your.owncloud.domain.name]/remote.php/webdav/ /home/pi/owncloud davfs rw,noexec,noauto,user,async,_netdev,uid=pi,gid=pi 0 0

then mount the drive by calling mount owncloud/  or by calling echo -e “y” | mount owncloud/   if your server has a self-signed certificate as mine has.

3.) My idea is to take a picture, say, every 10 minutes, and take them for 24 hours with any need to remove them manually. So, write a script like the following, name it “take_photo.sh” and make it executable:

filename="/home/pi/owncloud/myflat_$(date +%H%M).jpg"
raspistill -o /home/pi/image.jpg
mv /home/pi/image.jpg $filename

4.) Set up the crontab by calling crontab -e  and add the following line:

*/10 * * * * /home/pi/take_photo.sh

5.) You are finished. Raspberry pi will take every 10 minutes a photo and save them to your ownCloud where you have a beautiful picture viewer that you can access wherever you are on whatever for a device.
