: Possible Causes and Actions Taken
No video image. / Power does not turn on.
Is there any problem with the power cable for
connecting this product to the power supply unit?
(If the cable is too long or thin, this may increase
the resistance and prevent the voltage from being
properly supplied.)
N Connect using a cable with a thickness/length
specified for this product.
(A p.18 [Installation and Connection
Preparations] )
Is the port number to be used when the client
computer accesses to the camera via HTTP
correctly specified?
(If the port number is incorrect, the Built-in Viewer
menus will be displayed, but videos will not
appear, and a "Connection is failed" message will
be displayed instead.)
N Set the HTTP port value for the Built-in Viewer
to the same value specified for the HTTP
server port on the camera's Protocol page.
(A p.57 [[Protocol] Page] )
(A p.80 [[Unicast] Settings] )
The power does not turn on even when PoE
is used to supply power.
Is connection established using a PoE (compliant
with IEEE802.3af) power supply device and a
LAN cable of Category 5e or higher?
N Check the cable. For some PoE power supply
devices (such as a hub), power will not be
supplied when the number of PoE terminals
connected exceeds the limit of the total
electrical power that can be supplied. For
more information, please refer to the
instruction manual of the PoE power supply
device.
Power turns on, but shuts down once the
camera starts rotating.
Is there any problem with the power cable for

I do not know the IP address of the camera.
If no changes have been made to the factory
default settings, the IP address is 192.168.0.2,
and the subnet mask is 255.255.255.0.
If you have set the [IP Setting] to "DHCP
Enable" and if you start the camera on the LAN
where no DHCP server exists, you can start the
camera with the factory default IP address.
N If you have a computer connected to the same
LAN, search for the IP address using
"JVC-VN-SearchTool" on the computer.
I cannot display the Settings page of the
camera.
N Check the current settings of Internet
Explorer. When a proxy server is in use,
configure the proxy server settings of the
Internet Explorer accordingly.
Unable to install Built-in Viewer/a warning
message appears when I start the Built-in
Viewer.
N Check the current settings of Internet
Explorer. The Built-in Viewer consists of a
software component called ActiveX. The
ActiveX is usually installed when the Built-in
Viewer is used for the first time. However,
installation may be rejected depending on the
anti-virus software settings. In this case,
change the settings of the anti-virus software
before installing the Built-in Viewer.
When I install the Built-in Viewer,
authentication by VeriSign appears.
The Built-in Viewer has an electronic signature for
authentication by VeriSign.
If computers are connected to the Internet in the
network environment, the digital certificate of the
Built-in Viewer can be checked by VeriSign
authentication.
