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.
