11.6. IR Function
With the IR cut filter, the Camera can still catch a clear image at night time or in low light conditions.
For these cameras the following IR function modes are provided:
Auto :
The camera switches automatically from Colour mode to Black & White mode and back without switching on the
LEDs.
On :
The camera is always in B&W mode, the LEDs are always off.
Off :
The camera stays always in Colour mode.
Light Sensor Mode :
IR LED lights will be turned on/off depending on the light sensor.
Light On Mode :
In this mode, IR LED lights will always be on.
Light Off Mode :
In this mode, IR LED lights will always be off.
Smart Mode:
The Smart Mode enhances the monochrome/night mode stability in ascenario where IR illumination is dominant.
In this mode, when the external IR illuminator is turned on, the IR cut filter of the IP Camera will stay open (i.e.
monochrome/night mode), preventing the camera from returning to colour/day mode when the IR illumination is
dominant.
Additionally, the day/night IR switching mechanism will then depend on the ambient light level instead of the light
sensor (Light sensor mode) on the IR LED module.

11.7. WDR Function
The Wide Dynamic Range (WDR) function is for solving high contrast or changing light issues to improve the video
display. The WDR is adjustable from Low, Mid to Hi. A higher level of WDR represents a wider dynamic range, so
that the IP Camera can catch a greater scale of brightness.

11.8. Noise Reduction
The IP Camera provides multiple <Noise Reduction> options for delivering an optimised image quality especially
in extra low-light conditions.
The different level options for 3D Noise Reduction (3DNR) include Low, Mid and Hi. A higher level of 3DNR
generates relatively enhanced noise reduction.
