Introduction

How to make the script run on startup: sudo nano /etc/rc.local

start cam with sudo CAMERA=opencv python3 run.py to open on restricted port 80

How to make the script run on startup: sudo nano /etc/rc.local insert: sudo CAMERA=opencv python3 run.py &

to start an OpenCV session from bash, you can do this:

$ CAMERA=opencv python3 run.py

From a Windows command prompt you can do the same as follows:

on windows run: $ python run.py CAMERA=opencv $ py -3.7 run.py CAMERA=opencv

or: $ set CAMERA=opencv $ python run.py $ py -3.7 run.py

or on linux with gunicorn:
