5.5.
DAY & NIGHT
DAY/NIGHT is used to control the setting during day-time and night-time operation. Select the
mode according to the light condition.
5.5.1.
EXTERN (Not supported)
DAY or NIGHT is determined by the built-in light photo sensor.
5.5.2.
AUTO
Used when DAY or NIGHT is determined by light level through the lens and DAY from/to NIGHT is
switched automatically by the scene brightness. It is controlled by the AGC threshold level, AGC
margin and delay time.
5.5.2.1.
SMART IR (Available only with the built-in LED model)
SMART IR can be set to reduce the saturation of strong IR illumination in the night in any
menu of EXT, AUTO and B/W (NIGHT). Set to ON, SMART IR is enabled and ANTI-SAT. level
is controlled.
5.5.2.2.
ANTI-SAT. (Available only with the SMART IR is ON)
Sets the anti-saturation level 0~20. Setting high level avoids the saturation but the corners
of the image will be darker accordingly.
5.5.2.3.
AGC THRES
AGC (Auto Gain Control) is a threshold level which determines when to switch DAY from/to
NIGHT in AUTO mode. Higher value makes the camera switch DAY from/to NIGHT at brighter
illumination.
5.5.2.4.
AGC MARGIN
Sets the gap level switching from/to DAY (color) or NIGHT (B/W).
5.5.2.5.
DELAY
D
→
N DELAY is timed in seconds while camera maintains its status before Day to Night
switches.
DELAY Used to avoid the unwanted/frivolous switching by a short term lights such as light
from the passing car. Sets delay term low, middle or high.
