Owens li'll Webcams
Four cameras, monitoring three of my machines, and sometimes my cats, fish and apartment..
The three cameras attached to machines are RaspberryPI based, Octoprint and Laserweb controllers, using cheapie USB webcams and mjpeg_streamer.
I also have several Cheap-and-Cheerful ESP32 webcams running my own version of the example webcam software supplied by Expressif.
This much expanded version of the original example has better networking capabilities, light control, preference saving and more. It is actually quite popular on Github and Hackaday..
Disclaimer: Images update once per minute; these are not livestreams. And it's often night , or just boring..
