BURST
determines whether a colour burst signal keeps output or eliminated when
camera switches to B/W.
If set to ON, B/W video signal contains colour burst signal and is compatible
with the colour equipment but shows the same resolution as colour video.
If set OFF, the colour burst signal is removed from B/W video and shows better
resolution but rarely the compatibility problem may occur with the colour
equipment.
DELAY CNT

DELAY CNT
is time in second while camera maintains its status before Day <–>
Night switches. DELAY can avoid the unwanted/frivolous switching by a short
term lights such as light from the passing car.
DAY –> NIGHT
005
DAY –> NIGHT
is a threshold level which determines to switch from DAY to NIGHT.

If it stays in Day (Colour) mode at night time, increase DAY –> NIGHT threshold
value until it just switches to Night.

CAUTION: If the gap between DAY –> NIGHT and NIGHT –> DAY is not big
enough, camera may repeat Day <–> Night switches.
