5 Setup
Exposure
• Anti-flicker: Select the anti-flicker mode depending on the environment:
◦ Outdoor: The system will use the exposure mode to adjust for lighting.
◦ 50Hz: The system will compensate for lighting using 50Hz AC power (i.e. for
Europe).
◦ 60Hz: The system will compensate for lighting using 60Hz AC power (i.e. for
North America).
• Mode: Select the exposure mode:
◦ Auto: The system will automatically adjust the brightness and exposure based
on the environment.
◦ Gain Priority: The system will automatically adjust the gain to reduce the
amount of noise in the image. Set the minimum and maximum Gain Scope. In-
creasing the max gain will increase the noise reduction.
◦ Shutter Priority: The system will automatically adjust the shutter to reduce mo-
tion trails in the image. Set the minimum and maximum Shutter Scope.
◦ Manual: Configure manual exposure settings. Configure the Shutter Regulate
and Gain Scope.
• 3D NR: Select ON to enable 3D spatial noise reduction. Under 3D NR Level, click
+ / - or use the slider to set the noise reduction value. The higher the value, the
greater the noise reduction. 3D noise reduction accomplishes the same process for
moving objects as well, providing clearer images in low light conditions. Removing
noise from the camera image reduces your recording file size and makes videos
clearer and more detailed.

Backlight
• Mode:
◦ OFF: Turn off the backlight function.
◦ BLC (Backlight Compensation): The camera automatically adjusts the expo-
sure for a clearer image in the darkest areas of the video. Click Default to use
default settings or Customized to adjust the BLC area. The darker the area you
select, the brighter the image will be.
