Automatically adjusts the focus position to maximize the high frequency content
of the picture in a center measurement area, taking into consideration the high
luminance and strong contrast components. The focus of the dome camera can be
operated in two modes: Manual Focus mode and Auto Focus mode. Different
settings for various models are described as follows.
