You can adjust the automatic settings.
BURST - This is a signal sent out by the camera even when no
color information is available. Some DVRs or security video capture
cards may require this to recognize the camera. Q-See security
DVRs do not need a burst signal and it may be turned off.
DELAY CNT - The time interval delay before switching from day
to night mode.
DAY NIGHT - Sets the threshold level for when the camera
should switch to night mode.
DAY/NIGHT MODE
This allows you to set the camera to switch automatically from day to night mode (the default) or to permanently set it to Color or B/W
operation. Please note that even when the camera is set to Color mode, it will switch to black and white night vision when there is no
longer enough ambient light to support color video.
NR (NOISE REDUCTION)
In low-light situations, there may be an increase in
“noise” (graininess or random speckles in the video).
Noise reduction can be turned off or set to reduce noise
in the black and white (Y) and/or color (C) portions
of the signal. The value ranges for both the Y and C
filters is 0-15. The higher the value, the more noise is
reduced, but this can reduce image sharpness.

IMPORTANT! The DAY NIGHT and NIGHT DAY operations should be tested during installation. Block the lens
for a few seconds to force a switch to night mode. Once the lens is unblocked, the camera should switch back to
day mode in less than 10 seconds. If it does not, slightly increase the threshold in the NIGHT DAY setting. A dimly
lit area or a very low iris setting may also prevent a return to day mode.
NIGHT
DAY - Sets the threshold level for when the camera should switch to day mode.
The value range for both thresholds is 0-255.
