In manual tracking mode, when a target object goes directly beneath the dome, the video will
automatically flips 180 degrees in horizontal direction to maintain continuity of tracking. This
function can also be realized by
auto mirror image depending on different camera models.

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 slowdown 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
