with stepping motor lens.
Chances are while moving the lens around the surveillance area, focusing can be slow when
zooming in on a complex scene with no distinctive objects especially in the center of the eld
of view. If this occurs, you can select the Custom mode, and congure a Focus window in the
middle of the eld of view.
With a Focus window in the center or a place you prefer in the FOV, the camera can more
rapidly focus on an object of your interest while scanning through the entire surveillance area.

window within your current eld of view to acquire the best focus out of it.

window that is showing a consistent color or texture. This function will not take effect if you set
the focus window on a distant background.
