Day/Night Switch
Day/Night Switch provides options for 'Auto', 'Day' and 'Night'.
Auto
Depending on the light conditions, the camera switches between day and night mode automatically. The
sensitivity can be set between 0 and 7.
Day
In this mode, the camera only outputs colour pictures.
Please note:
Only use this mode if the light conditions remain constant.
Night
In this mode, the camera only outputs black/white pictures.
Please note:
Only use this mode if the light conditions are poor.
Schedule
Sensitivity
Setting for the switching threshold for automatic day/night switching (0–7).
A lower value means that there is a lower lighting level for switching to night mode.
Delay Time
Setting a delay time between recognising that a switching is required and carrying out the process.
Smart IR
This function can reduce the cross-fade of the video image, in the event that light is reflected from nearby
objects.
Backlight Settings
WDR
With the aid of the WDR function, the camera can return clear pictures even in disadvantageous backlight
conditions. If there are both very bright and very dark areas in the picture area, the brightness level of the
overall picture is balanced to provide a clear, detailed image.
Click on the checkbox to enable or disable the WDR function.
Set the Wide Dynamic Level higher to enhance the WDR function.
