SELECTING EXPOSURE SETTINGS
1. Place your mouse pointer over the Imaging tab.
2. Select Exposure from the drop-down menu.
3. Set the exposure priority to Noise or Frame Rate. Exposure priority allows you to select the desired behavior when auto exposure settings
conflict with the desired frame rate selected on the stream configuration page.
Noise: This setting prioritizes the best image quality in all conditions regardless of your desired frame rate.
Frame Rate: This setting prioritizes a guaranteed frame rate in all lighting conditions.
4. Move the slider to the left or right to change the following settings:
Max Exposure Time: Controls the maximum time in milliseconds that the sensor is exposed to the light. Move the slider to the left to
decrease the maximum exposure time, which decreases light sensitivity and reduces motion blurring. Move the slider to the right to
increase the maximum exposure time, which increases light sensitivity and motion blurring. The available range of maximum exposure
settings is 1 to 500 msec; the default setting is 33.3 msec.
Max Gain: Increasing the gain increases the brightness of the image, but it also increases the amount of noise in the image. Move the
slider to the desired position. The available gain settings are 0 to 100. The default setting is 100.
5. Set the Flicker Correction mode to Auto, On, or Off.
Auto: This setting automatically reduces rolling shutter flicker in scenes with low dynamic range, but it does not reduce picture flicker in
scenes with high dynamic range.
On: This setting reduces rolling shutter picture flicker, and it dramatically reduces the amount of dynamic range in the image.
Off: This setting maintains the maximum amount of dynamic range in the image, but it can produce rolling shutter picture flicker in scenes
with florescent or other oscillating light sources. Off is the default setting.
6. If required, click the Restore Settings to Defaults button to restore the default settings.
DAY NIGHT SETTINGS
The Day Night mode controls the position of the IR cut filter, which determines the color or black-white setting of the camera. The Day Night
mode settings change depending on the Exposure settings. If the Day Night mode is set to Auto, the transition settings are available. If the
camera is set to Manual mode, the only available Day Night mode setting is Position, which sets the IR filter to either the day (color) position or
the night (black-white) position.
SELECTING DAY NIGHT AUTO MODE
1. Place your mouse pointer over the Imaging tab.
2. Select Exposure from the drop-down menu.
3. Select Auto for the Day Night mode. The auto setting automatically controls the IR cut filter depending on the Transition Level setting.
4. Set the transition level to the Lighter, Default, or Darker setting. The Transition Detect Time setting determines when the device changes
from day mode (color) to night mode (black-white).
5. Move the Transition Detect Time slider to the desired position. The Transition Detect Time setting determines the frequency at which the
device checks for sufficient ambient light to transition to day mode or night mode. Detection times are 0 to 60 sec.; the default setting is
5sec.
6. If required, click the Restore Settings to Defaults button to restore the default settings.
SELECTING DAY NIGHT MANUAL MODE
1. Place your mouse pointer over the Imaging tab.
2. Select Exposure from the drop-down menu.
