WDR
To enhance video display, the wide dynamic range (WDR) function solves high contrast or
changing light issues by taking the best of two pictures with different exposure settings. WDR
is especially effective in solving indoor and outdoor contrast issues. The user can enable or
disable the WDR function, according to the application.
Inverse
With the Inverse function, the video in the camera preview can be rotated 180°.
Autocalibration
There is one horizontal and one vertical infrared ray check point in each dome. When the
dome camera's position is moved during installation or maintenance, the relative distance
between the original set point and the check point may change. When enabled, the
autocalibration function automatically detects this change and resets the point back to the
original position.
2DNR
With the 2D Noise Reduction function, the processor analyses pixel by pixel and frame by
frame to eliminate environmental noise signal so that a high quality image can be produced
even in low light conditions.
3DNR
In addition to 2D Noise Reduction, the HSD820H3 also includes 3DNR which generates
enhanced noise reduction.
Stabilizer
The HSD820H3 has a built-in image stabiliser to prevent vibrations from disrupting a camera
view or footage, such as those caused by wind in pole-mount installations. Enable this
function to provide stable pictures even at the highest zoom ratio.
