Here you go: https://stty.io/2020/07/31/lamp-control-based-on-video-confe...

I’ve been using this for ~1 and it’s been more reliable than I expected - no maintenance required even with the update to Big Sur.

To save you a click:

log show --predicate 'subsystem == "com.apple.VDCAssistant" && \ eventMessage CONTAINS[c] "kCameraStream"' --last 1m --no-debug --no-pager \ --style compact | tail -n +2)

#or log stream ... # streaming is better to generate events
