Privacy Mask
This function allows you to block or mask certain area of a scene, for preventing the
personal privacy from recording or live viewing. A masked area will move with pan
and tilt functions and automatically adjust in size as the lens zooms telephoto and
wide.
3D Positioning
In the client software, use the left key of mouse to click on the desired position in the
video image and drag a rectangle area in the lower right direction, then the dome
system will move the position to the center and allow the rectangle area to zoom in.
Use the left key of mouse to drag a rectangle area in the upper left direction to move
the position to the center and allow the rectangle area to zoom out.
Proportional Pan/Tilt
Proportional pan/tilt automatically reduces or increases the pan and tilt speeds
according to the amount of zoom. At telephoto zoom settings, the pan and tilt
speeds will be slower than at wide zoom settings. This keeps the image from moving
too fast on the live view image when there is a large amount of zoom.
Auto Focus
The auto focus enables the camera to focus automatically to maintain clear video
images.
Day/Night Auto Switch
The speed domes deliver color images during the day. And as light diminishes at night,
the 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.
This feature varies depending on speed dome models.
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
