Now I’m using two Microsoft LifeCam Cinema webcams with 720p resolution, one in my window facing east and one on the roof facing west (this one is connected to my server using a 20m active USB extension cable).

I’m using infinite focus, no white balance correction and auto exposure correction on my webcams. To set these settings, I’m using v4l2ctrl. It can export the current settings using v4l2ctrl -d /dev/video -s file, and after editing it can load it to the specified device: v4l2ctrl -d /dev/video -l file I’m using this file for […]
