5 Inch Network High-definition Speed Dome User Manual

Limit Stops
The dome can be programmed to move within the limit stops (left/right, up/down) which are configurable by the control keyboard,
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 called, 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 displayed 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 different 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 speed 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.
Please refer to Section 4.2.2 3D Intelligent Positioning for the specific instructions.
Note:

Proportional Pan/Tilt
Proportional pan/tilt 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
conditions.

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)
