Day/Night
Auto - the camera switches the IR cut-off filter on and off depending on the scene
illumination level.
Monochrome - the IR cut-off filter is removed, giving full IR sensitivity.
Color - the camera always produces a color signal regardless of light levels.
Automatic exposure
Select to let the camera automatically set the optimum shutter speed. The camera tries to
maintain the selected shutter speed as long as the light level of the scene permits.
–
Fixed exposure
Select the Fixed shutter [s] for fixed exposure. (The values available depend on the value
set for the ALC mode).
Day-to-night switchover
Adjust the slider to set the video level at which the camera in Auto mode switches from
color to monochrome operation (-15 to +15).
A low (negative) value means that the camera switches to monochrome at a lower light
level. A high (positive) value means that the camera switches to monochrome at a higher
light level.
Night-to-day switchover
Adjust the slider to set the video level at which the camera in Auto mode switches from
monochrome to color operation.
A low (negative) value means that the camera switches to color at a lower light level. A high
(positive) value means that the camera switches to color at a higher light level.
(The actual switch-over point might change automatically to avoid instable switching.)

Intelligent Dynamic Noise Reduction
Select On to activate intelligent Dynamic Noise Reduction (DNR) which reduces noise based
on motion and light levels.
Sharpness level
Adjusts the Sharpness level between -15 and +15. A low (negative) value makes the picture
less sharp. Increasing sharpness brings out more detail. Extra sharpness can enhance the
details of license plates, facial features and the edges of certain surfaces but can increase
bandwidth requirements.
Temporal noise filtering
Adjusts the Temporal noise filtering level between -15 and +15. The higher the value, the
more noise filtering.
Spatial noise filtering
Adjusts the Spatial noise filtering level between -15 and +15. The higher the value, the
more noise filtering.
Backlight compensation
Select Off to switch off backlight compensation.
Select On to capture details in high-contrast and extremely bright-dark conditions.
Contrast enhancement
Select On to increase the contrast in low contrast conditions.
