XDNR (eXcellent Dynamic Noise Reduction)

XDNR is our noise reduction technology for network security cameras. XDNR utilizes 2D and 3D noise reduction methods adaptively to scenes. 2D noise reduction (2DNR) reduces noise on the image by maintaining a smooth edge on moving objects, while 3D noise reduction (3DNR) drastically reduces noise on the image of still objects. Under low-light conditions, XDNR provides clear images for both moving objects and still portions of the image, using 2DNR and 3DNR respectively. This method provides clear images while minimizing motion blur, which is a typical challenge in outdoor surveillance monitoring applications such as in parking lots.
