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.
(Digital) 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, Digital 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 dome supports the power off memory capability with the predefined resume time. It allows
the dome to resume its previous position after power is restored.
Park Action
This feature allows the dome to start a predefined action automatically after a period of inactivity.
User Management
The dome allows you to edit users with different levels of permission, in the admin login status.
Multiple users are allowed to access and control the same network PTZ via network
simultaneously.
3D Digital Noise Reduction (DNR)
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.
