I am playing around with the logitech c920 connected to a Raspberry Pi 4 and being used as a baby monitor. Hence I would like to turn off the blue status light if possible; preferably via unix command line.

Is that possible?

I actually found the answer in this blog. It might work with other logitech cameras too.

sudo apt-get install uvcdynctrl
sudo uvcdynctrl -i /usr/share/uvcdynctrl/data/046d/logitech.xml

# LED off
uvcdynctrl -s 'LED1 Mode' 0
# LED on
uvcdynctrl -s 'LED1 Mode' 1
# LED blinking
uvcdynctrl -s 'LED1 Mode' 2
# LED auto mode
uvcdynctrl -s 'LED1 Mode' 3
