Day/Night Delay (seconds): Set the delay time, in seconds, before the Day/Night mode switch
l
is made once the set threshold is reached.
Enable IR LED: You can manually enable or disable the IR illuminators that are installed on the
l
camera.
Enable Adaptive IR Compensation: You can enable automatic infrared adjustments through
l
Adaptive IR Compensation. This allows the camera to automatically adjust the video image for
saturation caused by IR illumination.
Show Auto Contrast ROI: Enabling this option allows you view and select the region of
l
interest. The contrast is automatically adjusted based on the selected region.
Enable Night Visibility Check: You can manually enable or disable the night visibility check on
l
a camera. The night visibility check, when enabled, performs a periodic test switching between
day/night mode to check if there is sufficient light level to switch from night mode to day mode.
When disabled, the camera will use a less optimal method to determine if the light level is
sufficient to switch to day mode.
Note: Disabling the night visibility check could delay the camera from transitioning
between night and day modes and make the transition time less optimal. For example,
the camera stays in night mode 30 minutes longer than it needs to.
5. To adjust the exposure of the image, adjust the Exposure Settings:
Flicker Control: If your video image flickers because of fluorescent lights around the camera,
l
you can reduce the effects of the light by setting the Flicker Control to the same frequency as
your lights. Generally, Europe is 50Hz and North America is 60Hz.
Note: Resetting this control will stop the video stream for a few seconds.
Enable Wide Dynamic Range: You can enable automatic color adjustments through Wide
l
Dynamic Range (WDR). This allows the camera to adjust the video image to accommodate
scenes where bright light and dark shadow are clearly visible.
Exposure: You can allow the camera to control the exposure by selecting Automatic, or you
l
can set a specific exposure rate.
Note: Increasing the manual exposure time may affect the image rate.
