Proportional pan/tilt
Proportional pan/tilt automatically reduces or increases the pan and tilt speeds according to
the amount of zoom. In telephoto zoom mode, the pan and tilt speeds are slower than in wide
angle zoom mode. This keeps the image from moving too fast on the live view image when
there is a large amount of zoom.
Autofocus
The autofocus function enables the camera to focus automatically to maintain clear video
images.
Day/Night autoswitch
The speed domes deliver colour images during the day. As light diminishes at night, the speed
domes switch to night mode and deliver black and white images with high quality.
Slow shutter
In slow shutter mode, the shutter speed is automatically reduced in low illumination
conditions to maintain clear video images by extending the exposure time. The feature can be
enabled or disabled.
Backlight compensation (BLC)
If you focus on an object against strong backlight, the object will be too dark to be seen
clearly. The backlight compensation (BLC) function can compensate the light in front of the
object to make it clear, but this causes overexposure of the background where the light is
strong.
Wide dynamic range (WDR)
The wide dynamic range (WDR) function helps the camera provide clear images even under
difficult 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.
Note: This feature varies depending on the speed dome model.
White balance (WB)
White balance can remove unrealistic colour casts. White balance is the white rendition
function of the camera to automatically adjust the colour temperature according to the
environment.
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.
Time 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, and other actions.
Park action
This feature allows the dome to start a predefined action automatically after a period of
inactivity.
