• Day/Night Switch
Day/Night Switch function can provide color images in te day mode and black/white images in night
mode. Switch mode is configurable.
 Day: The image is always in color.
 Night: The image is always black/white.
 Auto: The camera automatically switches between day mode and the night mode according to the
illumination.
• Scheduled-Switch: Set the Start Time and the End Time to define the duration for day mode.
• Triggered by Alarm Input: Two trigger modes are available: Day and Night. For example, if the trigger
mode is Night, the image turns black and white when the device receives an alarm input signal.
Day/Night Switch function varies by model.
• Grey Scale: You can choose the range of the Grey Scale as [0-255] or [16-235].
• Rotate: When enabled, the live view will rotate 90 ° counterclockwise. For example, 1280 × 720 is
rotated to 720 × 1280.
Enabling this function can change the effective range of monitoring in the vertical direction.
• Lens Distortion Correction: For devices equipped with a motorized lens, image may appear distorted to
some extent. Enable this function to correct the distortion.
This function is supported only by certain devices equipped with a motorized lens.
The edge of image will be lost if this function is enabled.
• BLC: If you focus on an object against a strong backlight, the object will be too dark to be seen clearly.
BLC (backlight compensation) compensates light to the object in the front to make it clear. If BLC mode
is set as Custom, you can draw a red rectangle on the live view image as the BLC area.
• WDR: The WDR (Wide Dynamic Range) function helps the camera provide clear images in environments
with strong illumination differences.
When there are both very bright and very dark areas simultaneously in the field of view, you
can enable the WDR function and set the level. WDR automatically balances the brightness
level of the whole image and provides clear images with more details.
When WDR is enabled, other functions may not be supported. Refer to actual interface.
• HLC: When the bright area of the image is over-exposed and the dark area is under-exposed, the HLC
(High Light Compression) function can be enabled to weaken the bright area and brighten the dark
area, so as to achieve the light balance of the overall picture.
• White Balance: White balance is the white rendition function of the camera. It is used to adjust the
color temperature according to the environment.
