SECTION 1: OVERVIEW
Day/Night Auto Switch
The cameras deliver color images during the day. And as light diminishes at night, the cameras 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 camera supports the power off memory capability with the predefined resume time. It allows the camera to resume its previous
position after power is restored.
