Is there a way to change the focus of a local usb camera in ZoneMinder?
Or should "v4l2-ctl" be used from outside ZoneMinder?

Optical focus?
No, I believe you'll have to do that with external code.

Well, focus or other settings. I think the focus is the problem.
It look like it is possible to change it from cli:
v4l2-ctl --set-ctrl=focus_absolute=100
or
v4l2-ctl --set-ctrl=focus_auto=0
Example from an other application:
Focus — Focus is set to auto by default on the C930e Webcam. To manually adjust the Focus, click on the checkbox next to the Focus slider. Click and drag the slider to the right to increase and to the left to decrease, or set a value manually by typing a number in the box.
