Troubleshooting
1.
The
camera
can’t
be
accessed
or
access
is
slow
There
might
be
a
problem
with
the
network
cable.
To
confirm
that
the
cables
are
working,
ping
the
address
of
a
known
device
on
the
network.
If
the
cabling
is
OK
and
your
network
is
reachable,
you
should
receive
a
reply
similar
to
the
following
(…bytes
=
32
time
=
2
ms).
Another
possible
problem
may
be
that
the
network
device
such
as
a
hub
or
switch
utilized
by
the
Network
Camera
is
not
functioning
properly.
Please
confirm
the
power
for
the
devices
are
well
connected
and
functioning
properly.
2.
The
camera
can
be
accessed
locally
but
not
remotely
This
might
be
caused
by
a
firewall.
Check
the
Internet
firewall
with
your
system
administrator.
The
firewall
may
need
to
have
some
settings
changed
in
order
for
the
Network
Camera
to
be
accessible
outside
your
local
LAN.
For
more
information,
please
refer
to
the
section
about
installing
your
camera
behind
a
router.
Make
sure
that
the
Network
Camera
isn’t
conflicting
with
any
Web
server
you
may
have
running
on
your
network.
The
default
router
setting
might
be
a
possible
reason.
Check
that
the
configuration
of
the
router
settings
allow
the
Network
Camera
to
be
accessed
outside
your
local
LAN.
3.
White
vertical
lines
appear
on
the
image
from
the
camera
It
could
be
that
the
CMOS
sensor
(a
square
panel
situated
behind
the
lens
that
measures
the
light
signals
and
changes
it
into
a
digital
format
so
your
computer
can
present
it
into
an
image
that
you
are
familiar
with)
has
become
overloaded
when
it
has
been
exposed
to
bright
lights
such
as
direct
exposure
to
sunlight
or
halogen
lights.
Reposition
the
Network
Camera
into
a
more
shaded
area
immediately
as
prolonged
exposure
to
bright
lights
will
damage
the
CMOS
sensor.
4.
The
camera
images
are
‘noisy’
Often
if
the
camera
is
in
a
low
‐
light
environment,
the
images
can
contain
a
lot
of
noise.
Try
enabling
Night
mode
and
see
if
that
improves
the
image
quality.
Otherwise,
try
to
use
the
camera
in
a
location
where
there
is
a
bit
more
light
source.
5.
Video
can’t
be
viewed
through
the
web
browser
interface.
ActiveX
might
be
disabled.
If
you
are
viewing
the
images
from
Internet
Explorer
make
sure
ActiveX
has
been
enabled
in
the
Internet
Options
menu.
You
may
also
need
to
change
the
security
settings
on
your
browser
to
allow
the
ActiveX
plug
‐
in
to
be
installed.
If
you
are
using
Internet
Explorer
with
a
version
number
lower
than
6,
then
you
will
need
to
upgrade
your
Web
browser
software
in
order
to
view
the
streaming
video
transmitted
by
the
Network
Camera.
Try
also
viewing
the

Ensure
that
you
have
the
latest
version
of
Java
installed
before
you
do.
