Wide Dynamic Vision Card
Introduction
The Wide Dynamic Vision Card provides four extra functions to the huperDVR 2400
surveillance system, which include night vision, sharpness adjustment, noise reduction and size
filtering of moving objects. These features are optional to be applied on video sources that are
connected to the Wide Dynamic Vision Card.
Functions Description
Visibility Makes the video visible even though the field of view is in a low illuminated
Enhancement environment, especially for night and backlighted situations.
Sharpness Sharpens blurred images or text caused by loss of focus.
Noise Reduction Reduces video signal noise to improve the video quality and minimize the
record size.
Size Filtering Detects moving objects that match the specified size criteria to reduce false
alarm activations.
