The backlight compensation level ranges from 000 to 100.
NOTE: If this function is enabled, the WDR function (for
23× model only) will
be disabled automatically. For details, refer to section 3.3.19 WDR Setting

3.3.3 FOCUS
Automatically adjusts the focus position to maximize the high frequency content of the
picture in a central measurement area, taking into consideration the high luminance
and strong contrast components. The focus on the PTZ camera can be operated in
two modes: Manual focus mode and auto focus mode. Different settings for the
various models are described below.
18×/26× Model:
• AUTO
The optimum focus is achieved using the internal digital circuit. There are 3
modes for users to select for different conditions.
Normal AF (auto focus) mode: The PTZ camera will automatically adjust the
focus of the picture.
Zoom trigger mode: When the zoom ratio is changed using the TELE or
WIDE buttons on the control keyboard or another control unit, the PTZ camera
will automatically adjust the focus again after a period of time (the preset value
is initially set to five seconds).
Interval AF mode: This mode is used for AF movements carried out at
particular intervals. If users pan/tilt the PTZ camera, the PTZ camera will
focus automatically after a period of time. The preset value is five seconds.
