occurs, meaning the IR sensor will deactivate, when the light sensor detects more light when in night
mode (i.e. a sunrise).
A time-based setting can be scheduled to activate/deactivate the IR sensor.
WDR (Wide Dynamic Range)
WDR helps with scenarios where illumination varies in the camera’s field of view. WDR will provide a
clear image in these scenarios.
The WDR Auto options are: Auto, Open, Close.
When Auto is selected, WDR will activate when the IP Camera is in Day mode (meaning the IR sensor is
deactivated) & will deactivate with the IP Camera is in Night mode. WDR is deactivated in night mode to
enhance the image quality when the IR sensor is activated.
When Open is selected, WDR is activated and WDR strength option can be adjusted to best suit the
environment.
When Close is selected, WDR is disabled.
The Light Adjust options are: Close, HLC, and BLC.
When Close is selected, the Light Adjust option is disabled.
When HLC is selected, the strength option is enabled. HLC, Highlight Compensation, is used when
there is overexposure on the IP Camera (i.e. car headlights pointing at the IP Camera). Enabling HLC will
reduce any glare from powerful light sources.
When BLC is selected, the strength option is also enabled. BLC, Backlight Compensation, is used when
there is natural light coming from behind an object or person. This results in dark image of the object or
person (i.e. silhouette). Enabling BLC will show the appropriate exposure of the object or person when
there is a strong background light source.
