7.5.7 WDR Function

The Wide Dynamic Range (WDR) function resolves high contrast or changing light issues in order to
enhance the video display. The WDR is adjustable from Low, Mid to Hi. A higher level of WDR
represents wider dynamic range, so that the IP camera can capture a greater scale of brightness.

7.5.8 Noise Reduction

Different level options for 3D Noise Reduction (3DNR) include Low, Mid and High. A higher level of
3DNR generates relatively enhanced noise reduction.
The proprietary Smart Picture Quality (SPQ) video processing method can drastically minimize
motion blur and provides clear images even in low-light environment. The combination of SPQ and
3DNR at different levels further yields exceptional video performance in various conditions.
The Noise Reduction function reduces image noise/snow, enabling the IP camera to deliver clearer
images in low-light conditions. The Noise Reduction is adjustable from 3DNR Low, 3DNR Mid, 3DNR
Hi, SPQ, SPQ + 3DNR Low, SPQ + 3DNR Mid, to SPQ + 3DNR Hi. Press <√> to confirm the new setting.
