How to use

Follow the instructions provided by the PyImageSearch link provided above. These will create a Python virtual environment with all the needed packages. Whenever you want to run the code, you will have to activate this virtual environment and finally launch:

python pi_surveillance.py -c conf.json

Note that the the conf.json file needs to be edited with the correct Dropbox token and URL to save the images.

Sample results

Images of Mika eating her treat sneakily after hiding under the blanket in a fully dark room can be found in the sampleResultImages directory.

VNC (Virtual Network Computing)

If you want to use VNC to run the application on a remote desktop, you have to enable VNC on the Raspberry Pi (run sudo raspi-config) and then follow the instructions on the official Raspberry page for VNC, which will ask you to install the VNC viewer on your desktop. Once logged in, remember to enable the virtual environment and then launch the application as described above.
