With 2D / 3D Digital Noise Reduction (D.N.R.), the processor analyzes pixel by pixel and frame
by frame to eliminate environmental noise signal so that the highest quality image can be
produced even in low light conditions. In comparison with 2D D.N.R., 3D D.N.R. generates
better de-noising effects.

Auto Focus
The focus of the camera can be set in three different modes: Constant, Manual and Spot.
Constant
Select <CONSTANT> and the camera will adjust the focus automatically and continuously in
any condition.
Manual
Select <MANUAL> to adjust the focus manually via the control keyboard.
Spot
When <SPOT> is selected, the camera will only activate Auto Focus after it stops movement.
Once the camera is focused, Auto Focus is inactive until the camera moves again.
Digital Zoom
You can enable Digital Zoom from <2x> to <12x>. The Digital Zoom will be activated after the
full Optical Zoom level is reached. The default setting is <OFF>.
Notice!
The difference between optical and digital zoom is that optical zoom uses the lens within the
camera to draw the image closer via zoom in or out to achieve the desired effect. Optical
zoom remains the same quality and full resolution of the zoomed image. On the other hand,
Digital zoom takes a portion of an image and expands the partial image to the full size of the
original image. Therefore, the image quality will be reduced.
