Setting the Slow Shutter
The shutter speed setting determines how long the image sensor is exposed to light. To see a
clear image in a dark environment, it is recommended you enable the Digital Slow Shutter
function and select a slower shutter speed. Slow Shutter is set to
OFF by default.
If the Digital Slow Shutter function is enabled, the HDZ Series Analogue PTZ Dome will
automatically adjust the shutter speed based on the light condition of the camera installation
environment. Digital Slow Shutters enables users to see objects in a dark environment below
0.1 lux.
Setting the Digital Noise Reduction
With 2D / 3D Digital Noise Reduction (DNR), the camera processor analyzes pixel by pixel and
frame by frame to eliminate environmental noise so that the highest quality image can be
produced, even in low light conditions. In comparison with 2D-DNR, 3D-DNR eliminates more
noise from the image.
Note See Recommended WDR and DNR Settings By Scene Type on page 94 for more
information on the best scenes for enabling/disabling 2D/3D NR.
Select D.N.R. and press IRIS+ to open the Noise Reduction submenu (see Figure 4-6 ). From
this menu to can set 2D noise reduction ON or OFF . You can also set the 3D noise reduction to
a setting from 1 – 5 , or OFF (default setting). Select EXIT+SAVE and press IRIS+ to return to
the previous menu.
Note 3D noise reduction is strong in reducing noise around static objects, but may
cause trails behind fast moving objects in the video under low light.

horizontally (see Figure 4-7 ). Occasions to employ the function include conferences,
demonstration, testing, etc. The default setting is OFF .
Application Users can see the displayed images, for example, when a dome is placed on a
desktop in a conference room (as shown in Figure 4-7 ).
