Exposure
On this page, you can configure the Exposure measurement window, Exposure level, Exposure
mode, Exposure time, Gain control, and Day/Night mode settings. You can configure two sets of
Exposure settings: one for normal situations, the other for special situations, such as the day/night/
schedule mode.
Sensor mode:
► Panorama: By default, the firmware adopts the Panorama mode and tries its best to stitch the
imaging results from different sensors to form a coherent 180º panoramic view.
► Region: If you select the Region mode, the firmware will ignore the incoherence among images
and display 4 regional views according to their individual lighting conditions. You can select each
image sensor #1 to #4 using their specific check circle to configure the exposure configuration
individually.
Measurement Window: This function allows users to configure measurement window(s) for low
light compensation. For example, where low-light objects are posed against an extremely bright
background. You may want to exclude the bright sunlight shining through a building's corridor.
■ Full view: System calculates the full range of view and provides appropriate light compensation.
■ Custom: This option allows you to manually add customized windows as inclusive or exclusive
regions. A total of 10 windows can be configured. Please refer to the next page for detailed
illustration.
