l
External: The camera will open the IR cut filter and switch to monochrome mode based on the
digital input circuit state.
Note: The default digital input circuit state is configured on the Digital Inputs and
Outputs page. For more information, see
.
l
Enable IR: You can manually enable or disable the IR illuminators that are installed on the camera.
l
Enable Adaptive IR Compensation: You can enable automatic infrared adjustments through Adaptive
IR Compensation. This allows the camera to automatically adjust the video image for saturation
caused by IR illumination.
l
Show Auto Contrast ROI: Enabling this option allows you view and select the region of interest. The
contrast is automatically adjusted based on the selected region.
l
Enable Night Visibility Check: You can manually enable or disable the night visibility check on 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.
6. To adjust the exposure of the image, adjust the Exposure Settings:
l
Flicker Control: If your video image flickers because of fluorescent lights around the camera, 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.
l
Enable Wide Dynamic Range: You can enable automatic color adjustments through Wide Dynamic
Range (WDR). This allows the camera to adjust the video image to accommodate scenes where bright
light and dark shadow are clearly visible.
l
Exposure: You can allow the camera to control the exposure by selecting Automatic, or you can set a
specific exposure rate.
Note: Increasing the manual exposure time may affect the image rate.
