Functions overview
This section gives an overview of the functions offered by the speed dome camera.
Note: The availability of the functions may vary depending on the model of the camera.
Limit stops
The dome can be programmed to move within limit stops (left/right, up/down).
Scan modes
The dome provides five scan modes: auto scan, tilt scan, frame scan, random scan and
panorama scan.
Presets
A preset is a predefined image position. When the preset is called, the dome automatically
moves to the defined position. Presets can be added, modified, deleted and called.
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. It also guarantees that a
masked area is not revealed when the dome is moving to a preset.
Patrol
A patrol is a memorised series of predefined preset function. The scanning speed between two
presets and the dwell time at the preset are programmable.
Pattern
A pattern is a memorised series of pan, tilt, zoom, and preset functions. By default, the focus
and iris are in autostatus when the pattern is being memorised.
Label display
The on-screen label of the preset title, azimuth/elevation, zoom, time and dome name can be
displayed on the monitor. The displays of time and speed dome name can be programmed.
Autoflips
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 realised by auto mirror image, depending on different camera models.
Privacy mask
This function allows you to block or mask certain areas of a scene to prevent the personal
privacy from being violated by recording or live viewing. A masked area will move with pan
and tilt functions and will automatically adjust in size as the lens goes to telephoto and wide
angle.
3D Positioning
In the client software, use the left mouse button to click on the desired position in the video
image and drag a rectangle area in the lower right direction. The dome system will move the
position to the centre and allow the rectangle area to zoom in. Use the left mouse button to
drag a rectangle area in the upper left direction to move the position to the centre and allow
the rectangle area to zoom out.
