and panorama scanning. The scanning speed can be set by OSD menu from level 1 to 40, with the
corresponding speed ranging from/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, time, 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.
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.
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.
DAY/NIGHT Auto-switch
The speed dome delivers color images during the day; as light diminishes at night, it switches to
night mode and delivers black and white images with high quality. You can also switch it to NIGHT
mode manually to increase the sensitivity in low light conditions.
Wide Dynamic Range (WDR)
The wide dynamic range function helps the speed dome 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
White balance is the white rendition function of the speed dome to adjust the color temperature
according to the environment automatically. It can remove the unrealistic color casts in the image.
Patrol
The high speed dome support patrols. In each patrol, user is allowed to specify the scanning track
by a group of user-defined presets, with the scanning speed between two presets and the dwell
time at the preset separately programmable.
Pattern
A pattern is a memorized, repeating series of pan, tilt, zoom, and preset functions that can be
