Color
B/W
auto
switch:
The
camera
will
display
color
image
and
become
monochrome
automatically
at
night.
AGC:
When
the
object
being
shot
looks
dim,
please
turn
on
AGC
to
enhance
brightness.
To
output
standard
video
under
different
illumination,
the
range
of
auto
gain
control
must
be
large
enough.
When
under
low
illumination,
AGC
will
increase
camera’s
sensitivity,
and
output
bright
and
clear
video.
S/N
ratio:
It
is
the
ratio
of
Signal
voltage
and
noise
voltage.
If
the
ratio
is
larger,
the
effect
of
noise
is
less,
and
the
image
is
cleaner.
OSD
(On
Screen
Display):
The
camera
supports
user
‐
friendly
menu
interface
on
the
screen,
convenient
for
user
selecting
various
functions.
3
‐
axis
adjustment:
Advanced
3
‐
axis
mechanism
design
meets
different
mounting
requirement
by
flexibly
adjusting
the
lens
into
the
required
angle.
Synchronous
System:
Internal
synchronization
uses
synchronous
signal
which
is
generated
by
the
camera’s
crystal
oscillator
to
complete
synchronous
scan.
Power
synchronization
uses
synchronous
signal
which
is
generated
by
camera’s
adaptor
to
complete
synchronous
scan.
White
Balance:
A
camera
cannot
adjust
the
color
temperature
according
to
lighting
changes
as
well
the
human
eye;
this
causes
color
deviation.
White
balance
is
the
white
rendition
ability
of
the
camera
to
adjust
the
problem
according
to
the
environment
automatically.
ICR
Auto
Switch:
This
will
filter
infrared
light
during
the
daytime
and
change
to
normal
filter
at
night
to
ensure
a
high
sensitivity
and
clear
image.
BLC:
If
there
is
glaring
light
in
the
background
of
the
object
being
shot,
the
object
will
look
very
dim.
In
this
situation,
turning
on
the
BLC
function
will
make
the
object
look
bright
and
clear,
but
the
background
scene
will
be
overexposed.
