speeds will be slower than at wide zoom settings. This keeps the image from moving
too fast on the live view image 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 domes deliver color images during the day. And 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 will automatically slow down 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 BLC (Backlight Compensation) function can compensate light to the
object in the front to make it clear, but this causes the over-exposure 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 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.
Note: This feature varies depending on speed dome models.
 White Balance (WB)
White balance can remove the unrealistic color casts. White balance is the white
rendition function of the camera to adjust the color temperature according to the
environment automatically.
 Patrol
A patrol is a memorized series of pre-defined preset function. The scanning speed
between two presets and the dwell time at the preset are programmable.
 Pattern
A pattern is a memorized series of pan, tilt, zoom, and preset functions. By default
the focus and iris are in auto status during the pattern is being memorized.
 Power Off Memory
The dome supports the power off memory capability. It allows the dome to resume
its previous position after power is restored.
 Park Action
This feature allows the dome to start a predefined action automatically after a period
of inactivity.
 User Management
The dome allows you to edit users with different levels of permission, in the admin
login status. Multiple users are allowed to access and control the same network
speed dome via network simultaneously.
