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 resulting in clearer video.
3D Positioning
In the client software, use the click left mouse button on the desired position in the video image, and then drag a
rectangle area in the lower right direction. The dome system will move the position to the center and allow the rectangle
area to zoom in. Use the left key of the 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.
Auto Flips
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.
Auto Focus
The auto focus enables the camera to focus automatically to maintain clear video images.
Backlight Compensation
(BLC):
If you focus on an object against strong backlight, the object will be too dark to be seen clearly. The BLC function can
compensate light to the object in the front to make it clear. This can cause an over-exposure of the background where the
light is strong.
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.
Label Display
The on-screen label of the preset title, time and dome name can be displayed on the monitor. The displays of time and
speed dome name can be programmed.
Limit Stops: The dome can be programmed to move only within the limit stops (left/right, up/down).
Park Action This feature allows the dome to start a predefined action automatically after a period of inactivity.
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.
Preset Freezing:
This feature freezes the scene on the monitor when the dome is moving to a preset. This allows for smooth transition
from one preset scene to another. This also guarantees that a masked area will not be revealed when the dome is moving
to a preset.
Presets
A preset is a predefined image position. When the preset is called, the dome will automatically move to the defined
position. The presets can be added, modified, deleted and called.
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.
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.
Scan Modes: The dome provides five scan modes: auto scan, tilt scan, frame scan, random scan and panorama scan.
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.
