move the position to the center and allow the rectangle area to zoom in. Use the left key of
mouse to drag a rectangle area in the upper left direction to move the position to the center and
allow the rectangle area to zoom out.
Proportional Pan/Tilt
Proportional pan/tilt automatically reduces or increases the pan and tilt speeds according to the
amount of zoom. At telephoto zoom settings, the pan and tilt 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.
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 speed dome supports the power off memory capability with the predefined resume time. It
allows the speed dome to resume its previous position after power is restored.
