User Manual of Thermal Network Speed dome 3
speed domes switch to night mode and deliver black and white images with high quality.
 Slow Shutter
In slow shutter mode, the shutter speed will automatically slow down in low illumination
conditions to maintain clear video images by extending the exposure time. The feature can
be enabled or disabled.
 Backlight Compensation (BLC)
If you focus on an object against strong backlight, the object will be too dark to be seen
clearly. The BLC (Backlight Compensation) function can compensate light to the object in
the front to make it clear, but this causes the over-exposure of the background where the
light is strong.
 Wide Dynamic Range (WDR)
The wide dynamic range (WDR) function helps the camera provide clear images even
under back light circumstances. When there are both very bright and very dark areas
simultaneously in the field of view, WDR balances the brightness level of the whole image
and provide clear images with details.
 White Balance (WB)
White balance can remove the unrealistic color casts. White balance is the white rendition
function of the camera to adjust the color temperature according to the environment
automatically.
 Patrol
A patrol is a memorized series of pre-defined preset function. The scanning speed
between two presets and the dwell time at the preset are programmable.
 Pattern
A pattern is a memorized series of pan, tilt, zoom, and preset functions. By default the
focus and iris are in auto status during the pattern is being memorized.
 Power Off Memory
The speed dome supports the power off memory capability with the predefined resume
time. It allows the speed dome to resume its previous position after power is restored.
 Scheduled Task
A time task is a preconfigured action that can be performed automatically at a specific
date and time. The programmable actions include: auto scan, random scan, patrol
1-8 ,pattern 1-4, preset 1-8,frame scan, panorama scan, tilt scan, day, night, reboot, PT
adjust, Aux Output, etc.
 Park Action
This feature allows the speed dome to start a predefined action automatically after a
period of inactivity.
 3D Digital Noise Reduction
Comparing with the general 2D digital noise reduction, the 3D digital noise reduction
function processes the noise between two frames besides processing the noise in one
frame. The noise will be much less and the video will be clearer.
