7. Day/night cameras only: Set the Day Exposure Time and the Night Exposure Time.
Day Exposure Time: This setting is the maximum time in milliseconds that an image is exposed during daytime conditions. Decreasing
exposure time decreases the light sensitivity of the scene and reduces the streaking of fast moving objects (motion blur); however, it
increases the amount of noise in the scene. The day maximum exposure time range is 1 to 500 msec; the default setting is 33.3 msec.
Night Exposure Time: This setting is the maximum time in milliseconds that an image is exposed during nighttime (black-white)
conditions. Increase the exposure time to increase light sensitivity of the scene. The night maximum exposure time range is 1 to 500 msec;
the default setting is 120 msec.
8. Day/night cameras only: Set the Day Night mode to Auto or Manual.
Auto: Automatically controls the IR cut filter determined by the Transition Level and the Transition Detect settings.
Manual: Sets the IR filter to a fixed position. The filter can be set to the Day (color) position or the Night (black-white) position.
