Auto Focus

Some USB cameras such as the Microsoft Cinema HD use autofocus which causes false alerts in the security log. To prevent this turn off the auto focus.

 v4l2-ctl --verbose --set-ctrl=focus_auto=0

This command might require you to set the proper video input. In some cases updated ivtv-utils might need to be installed to allow v4l2-ctl to properly set the controls.
