DAY NIGHT AUTO Factory Default Descriptions
DELAY
5
DELAY is the duration which should maintain its status before making the
D –> N or N –> D switches. Camera checks the light level seamlessly if it
crosses over the threshold levels of D –> N LEVEL or N –> D LEVEL. To make
switching, the state must maintain unchanged for longer than DELAY time.
DELAY can avoid the unwanted/frivolous switching by a short term lights
such like the light from the passing car.
D –> N LEVEL
35
D –> N LEVEL is a threshold level to switch from DAY to NIGHT.
Higher value makes camera entered NIGHT at brighter light level.
TO ENTER NIGHT MODE AT LOWER ILLUMINATION, DECREASE it and vice
versa.
Try NOT to make the gap too small between D –> N LEVEL and N –> D
LEVEL to avoid the switch repeating.
N –> D LEVEL
85
N –> D LEVEL is a threshold level to switch from NIGHT to DAY.
Higher value makes camera exited NIGHT at brighter light level.
TO EXIT NIGHT MODE AT BRIGHTER ILLUMINATION, INCREASE it and vice
versa.
Try NOT to make the gap too small between D –> N LEVEL and N –> D
LEVEL to avoid the switch repeating.
NIGHT MODE
B/W
• If set to B/W, camera outputs B/W video at NIGHT.
In B/W mode, BURST can be set to OFF (default)/ON in DAY/NIGHT
B/W menu. BURST OFF shows sharper and better resolution but some
equipments may have a problem with BURST OFF.
• If set to COLOR, video is in colour at NIGHT when DAY/NIGHT in main menu
is AUTO.
For ICR versions, ICR switches out at NIGHT for both mode but its colour
may be inaccurate because IR spectrum couldn’t be cut out.
The settings for BURST will also affect any NIGHT mode.
IMPORTANT !!!
DAY -> NIGHT and NIGHT -> DAY operations must be examined and verified at the final step of the
installation. Block the lens for a few seconds for NIGHT mode and release and let it return to DAY mode.
If camera stays at NIGHT mode more than 10sec, decrease N –> D LEVEL a little and repeat the fore-
mentioned steps. If the scene is too dim or lens iris was adjusted near close, it may not return to DAY.
CAUTION
1) DAY/NIGHT AUTO menu is strongly recommended to be adjusted for the actual object after completing
all settings of lens and P/T/Z.
2) If the gap between D –> N LEVEL and N –> D-LEVEL becomes too small, it is easy to repeat switching
DAY from/to NIGHT.
Gap is recommended bigger than 45.
If the switching between DAY and NIGHT repeats, decrease D –> N and increase N –> D a little in turn
until the repeating stops.
