szdiyCam project runs on top of a Raspberry Pi with its camera board. It takes a picture every 20sec and uploads it to a custom image API server and QiNiu. The pictures taken are stored away in a local folder for later retrieval. The project is a community project by SZDIY Hackers' Community.

##Default Directory The default directory can be changed in

  1. /tmp for temporary picture storage before moving to a archive location
  2. /home/pi/szdiy_img stores every pictures taken. They are sorted by date into different folders.


  1. Clone the project

     cd szdiyCam
  2. Setup virtual environment to ensure anything you did inside the directory does not pollute OS

     virtualenv venv
  3. Activate virtualenv

     source venv/bin/activate
  4. Install dependencies using pip

     pip install -r requirements.txt 
  5. (optional) EXIF support

    • Install pyexiv2 which is used to make sure exif data is copied over correctly

        sudo apt-get install python-pyexiv2        
    • Link the pyexiv2 library to virtual environment

        ln -s /usr/lib/python2.7/dist-packages/ venv/lib/python2.7/site-packages/
        ln -s /usr/lib/python2.7/dist-packages/pyexiv2 venv/lib/python2.7/site-packages/
  6. copy to You will need to arrange your own picture API server there. The sample used QiNiu and a custom written API image server backend which is not part of this project. But it can be easily extended for other image uploading service such as Imagur API by creating your own uploading functions.

  7. If you get a QiNiu API key successfully setup in step 6, you can now run without any issues

  8. (Optional) A clear archive script is added for maintenance. You can add it to crontab so it can run once everyday. $ crontab -e 0 0 * * * python /home/pi/szdiyCam/ 1>>/home/pi/szdiycam_cleararchive.log 2>> /home/pi/szdiycam_cleararchive.log &

###Wechat 微信 Wechat is integrated in the uploading process. Our backend server handles normal picture upload and Wechat API at a single URL endpoint (not included in this project).

uploadAFileToLinodeWithWXMediaID handles uploading image to the Wechat server as well as our backend server. It reports the Wechat server response to our backend. Our backend will use this info to redeliver captured images stored on Wechat server to a Wechat App. To use without Wechat, use uploadAFileToLinode instead.

###Setup as System Service

  1. put uploadingimage under /etc/init.d/uploadingimage

  2. Make it executable

     sudo chmod +x uploadingimage
  3. Make it run at startup

     update-rc.d uploadingimage defaults
  4. For debugging purpose, you can reconnect this session by running

     sudo screen -r 'uploading image'
