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.

Is the lens cap attached?
N
Remove the lens cap.
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.
The power does not turn on even when PoE Plus
is used to supply power.
Is connection established using a PoE Plus (compliant
with IEEE802.3at Type 2) power supply device and a
LAN cable of Category 5e or higher?
N
Check the cable. For some PoE Plus power supply
devices (such as a hub), power will not be supplied
when the number of PoE/PoE Plus 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
Plus power supply device.
The power of the camera turns off when
VN-H657WPU is used in an environment under
-10°C.
N
When power is supplied using PoE Plus, the heater
will not work. Connect the VN-H657WPU to an AC
24 V power supply when using it in an environment
under -10°C.
Power turns on, but shuts down once the camera
starts rotating.
Is the adhesive tape attached during shipment
detached? Is there any foreign object inside the
product that prevents the camera from rotating?
If the camera unit is unable to rotate when you try to
turn it, the power will shut down automatically to protect
the equipment.
N
Remove the adhesive tape attached during
shipment, and check whether the camera unit
rotates by turning it manually.
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.

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.
Cannot find the menu items and operating items
of the Built-in Viewer described in the instruction
manual.
Is the firmware updated?
N
Check out the latest firmware from our website and
update the firmware as necessary.
