Deployment and Configuration Tips
The tips listed below are for your reference when using the Wide Dynamic Vision cards.
1. The minimum illumination for a camera is very important to make the Visibility Enhancement
effect most effective. In general, 0.1 LUX or below is recommended. In a closed environment
without any light sources, Visibility Enhancement applied to a general camera cannot work
the same way as an infrared camera.
2. If the field of view of a camera contains light sources or light reflection spots, mask them out
to get better Visibility Enhancement results.
3. If you are only interested in one portion of the camera view, apply Visibility Enhancement on
that portion only. The result will be better than applying Visibility Enhancement to the whole
camera view.
4. Sharpness adjustment helps sharpen a blurred field of view caused by focus loss, especially if
you want to sharpen blurred images or blurred text. Sharpness adjustment cannot further
enhance a clear field of view nor make it more visible.
5. Object size filtering during motion detection may have outstanding effects in certain cases. For
example, size filtering can be configured to ignore small-size objects such as flashing stars and
distant street lamps, and also configured to ignore camera shaking caused by wind blasting or
car passing by.
6. General camera devices in low lighting environments produce video signal noises. Video signal
noises always result in bad video quality and larger record size. Noise reduction helps eliminate
video signal noises to improve the video quality and minimize the record size.
Using Visibility Enhancement
The Visibility Enhancement option is available in the "Motion Detection" dialog box. Open the
"Motion Detection" dialog box to customize Visibility Enhancement settings. (See Figure 1)
