Semi-auto: The speed dome focuses automatically only once after panning, tilting and
zooming.
Manual: Use the "Focus -" and "Focus +" buttons on the PTZ control panel to focus
manually.
● Min. Focus distance is used to limit the minimum focus distance.
The minimum focus value varies depending on the model of the camera.
Day/Night Switch
To guarantee the image quality in different illuminations, the camera provides multiple sets of
parameters for the user to configure.
● The Day/Night Switch mode can be set to Auto, Day, Night, and Scheduled-Switch.
In Auto mode, the day mode and night mode can switch automatically according to the
light condition of the environment. The switching sensitivity can be set from 1 to 3.
In Day mode, the speed dome displays colour images. This mode is used for normal
lighting conditions.
In Night mode, the image is black and white. Night mode can increase the sensitivity in
low light conditions.
In Scheduled-Switch mode, you can set the time schedule by defining the start time and
end time for day mode. The camera will be in night mode for the remaining time in the
schedule.
● Smart Supplement Light: If the IR light is on and the image centre is overexposed, you
can enable this function.
● IRLightMode: In Auto mode, the brightness of the infrared light is adjusted
automatically.
● Brightness Limit: Move the slider to set a limit to the brightness of the infrared light.
Backlight Settings
If there’s a bright backlight, the subject in front of the backlight appears silhouetted or dark.
Backlight compensation (BLC) can correct the exposure of the subject. The backlight
environment will be washed out to white, however.
● BLC: Select an area from the list or set BLC to Auto.
● WDR: The wide dynamic range (WDR) function helps the camera provide clear images
when there are both very bright and very dark areas simultaneously in the field of view.
WDR balances the brightness level of the whole image to provide clear images with details.
Use the slider to set the WDR level. This function varies per camera model.
● HLC: Highlight compensation (HLC) makes the camera identify and suppress strong light
sources in a scene. This makes it possible to see image detail that would normally be
hidden.
