5.3.7. SETUP MENU 1
The SETUP MENU 1 is shown below.
The zoom speed of the Dome Camera is fixed (Value: 8). Users can choose to activate functions like Digital Zoom,
Slow Shutter, Noise Reduction, Image Inverse and Image Freeze. Please refer to the following description for use
of each function.
DIGITAL ZOOM:
With this item, users can enable or disable the 12× Digital Zoom. The Digital Zoom will start to activate after the
full Optical Zoom level is reached. A maximum of 12× digital zoom is allowed to be carried out. The default setting
is <ON>.
NOTE: The difference between optical and digital zoom is that the optical zoom uses the lens within the camera to
draw the image closer via zooming in or out for achieving the desired effect. Optical zoom keeps the same
resolution in the zoomed image as there was in the original image, therefore the image quality stays the same. In
contrast, the Digital zoom takes one part of the image and expands that image to the full size of the screen, in
doing so the image quality will be reduced.
SLOW SHUTTER:
The shutter speed determines how long the image sensor is exposed to light. The Dome Camera will
automatically adjust the shutter speed based on the light condition of the operating environment. With the Slow
Shutter function, the camera will still produce a clear image in low light conditions under 0.1 lux.
DIGITAL NOISE REDUCTION (D.N.R.):
With 2D / 3D Noise Reduction, the processor analyses pixel by pixel and frame by frame to eliminate
environmental noise signals so that the highest quality image can be produced, even in low light conditions. In
comparison with 2D D.N.R., the 3D D.N.R generates better denoising effects.
IMAGE INVERSE:
Users can select <ON> to inverse the displayed image vertically and horizontally (please see the figures shown
below). Occasions to employ the function include conferences, demonstration, testing, etc. The default setting is
<OFF>. When this function is enabled, the preset mask(s) will be set off automatically.
