1.3 Functions
- Multi-lingual OSD Menu
The dome provides multi-lingual OSD menu for display of system information and setting of dome parameters.
-
Self-adaptive to Multiple Protocols
The dome is compatible with PELCO-D, PELCO-P, PRIVATE-Code, VICON and KALATEL-32 protocol, etc., and is capable of
being self-adaptive to these protocols without need of selecting protocol by DIP switch settings.
-
Keyboard Control
The pan/tilt movement and zoom actions of dome can be controlled by the control keyboard, DVR, matrix, etc.
-
Limit Stops
The dome can be programmed to move within the limit stops (left/right, up/down) which are configurable by the control keybo-
ard, DVR or client application software.
-
Auto Scan
The dome provides 5 scanning modes: pan scanning, tilt scanning, frame scanning, random scanning and panorama scanning.
The scanning speed can be set by OSD menu from level 1 to 40, with the corresponding speed ranging from 1°/second to
40°/second.
-
Preset Freeze Frame
This feature freezes the scene on the monitor when going to a preset. This allows for smooth transition from one preset scene
to another and also guarantees that masked area will not be revealed when going to a preset.
-
Presets
Each of the user-definable presets can be programmed to use pan, tilt, camera settings and other settings. When preset is cal-
led, the dome will automatically move to the defined position. User is allowed to add, modify, delete and call each preset.
-
Label Display
The on-screen label of the preset title, azimuth/elevation, zoom and other operations can be programmed by menu and displa-
yed on the monitor.
-
Auto Flip
In manual tracking mode, when a target object goes directly beneath the dome, the dome will automatically rotate 180 degrees
in horizontal direction to maintain continuity of tracking. When the dome rotates (flips), the camera starts moving upward as long
as you continue to hold the joystick in the down position. This function can be realized by image center flip depending on dif-
ferent camera models. The feature can be enabled/disabled through the menu.
-
Privacy Mask
The privacy mask allows a user to program user-defined areas that cannot be viewed by the operator of the dome system. A
masked area will move with pan and tilt functions and automatically adjust in size as the lens zooms telephoto and wide.
-
3D Intelligent Positioning
The dome can be controlled with the 2 buttons and scroll of mouse can be used under PRIVATE-Code protocols with devices
and client software. Click on a certain area and the device will move to the scene with corresponding point as the center. When
a rectangular area is selected by left-clicking the mouse, device will move to its center and enlarge it. With right-clicking, the
lens will zoom in, and the scroll can easily make the lens zooming, and mouse operation automatically incorporates zooming
effect.
-
Proportional Pan
Proportional pan automatically reduces or increases the pan and tilt speeds in proportion to the amount of zoom. At telephoto
zoom settings, the pan and tilt speeds will be slower for a given amount of joystick deflection than at wide zoom settings. This
keeps the image from moving too fast on the monitor when there is a large amount of zoom.
-
Auto Focus
The auto focus enables the camera to focus automatically to maintain clear video images.
-
IR Cut Filter
The IR cut filter can be set to Auto, Day and Night. In auto mode, the camera is capable of automatically switching Black & White
mode (Night) and Color mode (Day) with regard to environment lightening conditions. In manual switch mode, user can increase
sensitivity in low light conditions by switching to Black & White mode, while the Color mode is preferred in normal lighting con-
ditions.
- Low Light Electronic Shutter
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/disabled by the menu.
- Backlight Compensation (BLC)
If a bright backlight is present, the subjects in the picture may appear dark or as a silhouette. Backlight compensation (BLC) en-
hances objects in the center of the picture. The dome uses the center of the picture to adjust the iris. If there is a bright light
source outside of this area, it will wash out to white. The camera will adjust the iris so that the object in the sensitive area is pro-
perly exposed.
