With VN-C30U Version 2, it has become possible to view images and to
perform various controls and settings of operations configurations via the
web browser.
This manual has been compiled in order to describe this new facility, which
is the “Control via Web Browser”. However, note that MPEG1 moving images
cannot be viewed and the image up-down inversion function is unavailable
via the web browser.

OPERATING ENVIRONMENT

The environment described below is necessary for operation of the VN-C30U
through a web browser.

A personal computer running the following web browser:

• The PC needs to satisfy the operational environment (P.10), which is
described in a separate volume of the manual.

•Web browser that has compatibility with Java Script and Frame:
Netscape Ver. 4.x or Internet Explorer Ver. 4.x, 5.x, 6.x is required.

• For the CPU performance and memory capacity requirements, refer to
the values recommended for the web browser in use.
To obtain smooth moving image displays on a large screen, a web
browser capacity above the recommended value is required.
Camera supplied images will not be displayed correctly in the 256­color mode.

In order to view a moving image with a Web browser, a JAVA VM is required.

CAUTION:

5If a Microsoft Corporation JAVA VM is not used to view a moving image, please

go to the following Homepage address for further advice.

http://www.jvc-victor.co.jp/english/pro/vnetworks/index-e.html

5A Microsoft VM is not provided with a WindowsXP SP1a.

LAN Environment

• The VN-C30U unit functions as a web server based on HTTP protocol.
Access linkage using a host name is possible if the environment allows
the DNS (Domain Name System) to be used.

• It is possible to connect a VN-C30U unit and a PC in a direct 1:1
connection by using a cross cable. (Certain LAN boards do not allow
the use of a cross cable, though this is a very rare case. Be sure to
check your LAN board.)

Web Page Illustrations Used in This Manual

Hereafter, the figures entitled VN-C30U Page show a display of the web
page data of the VN-C30U (including images captured by the cameras) by
the web page display function of the web browser.
Due to this mechanism, the format and character font of the displayed web
pages may be variable depending on the types and settings of the web
browser in use. Should the operation be hindered due to a lack of any of the
screen display items that should be displayed, adopt measures for displaying
all items by resizing the window, etc.
The figures in this manual are based on Netscape web page displays.

When the browser in use is Netscape

• When a moving image of the VN-C30U is displayed, the web page
display cannot be updated by changing the Netscape window size. In
this case, click on the <Update> button on the Netscape window to
update the web page display.

When the browser in use is Internet Explorer

• After the password has been changed, the password entry confirmation
window may ask for the password twice. In this case, enter the same
password twice.

• When the VN-C30U is connected through a proxy server, the correct
pan/tilt positions may sometimes not be enabled to be displayed. In
this case, click “Pan/Tilt” a few times until the correct display is obtained.

1-2 Changing the internal settings

Start the web browser.
In the web browser, specify the factory-set web page address of the
VN-C30U. (Direct specification of the factory-set web page address
enables the web browser to display the VN-C30U Top Page.)

http://192.168.0.2/index-e.html

Caution

If a proxy server is set for accessing the Internet, a direct specification
may not be permitted. In this case, change the proxy setting to permit
direct address specification.

Note:

● In this manual, the terms “Top page” and “Home page” are used as
described below:

Top page
Home page

: Indicates “index-e.html”
:•If the default page (See page 8) is set to valid, the

specified html page is indicated.

• If the default page is set to invalid, “index-e.html” is
indicated.

The VN-C30U Top page appears.

CAUTION

• The background changes to blue when the image mode of the VN-C30U
is set to the MPEG mode.

•The Top page will not appear if the “HTTP Viewing” is set to “Disable”
using the Setup Tool.
Instead the message “403 Forbidden” will be displayed.

Items in [Other Settings]

[DHCP] Set this to “Enable” when the DHCP is used.
[IP Address] To change to the IP address assigned to or approved for

the network administrator. (This is can be changed only
when DHCP is not used.)

[Subnet Mask] Similarly to the IP address, to set the value assigned to

or approved for the network administrator

[Default Gateway]

[Host Name] To specify the host name using up to 8 alphanumeric

[MAC Address] A physical address proper to each product.

To set the IP address of the default gateway
If this is not used, set “0.0.0.0”.

characters
This should be set when access linkage using a host
name is required in an environment allowing the use of
the DNS (Domain Name System). The host name is
displayed in the title bars of sub-windows including the
control windows.
Do not specify anything when the host name is not used
or unknown.

* This cannot be changed.

[Program Version] Program version of the firmware in the VN-C30U

unit.
* This cannot be changed.

[Password] To set the password using up to 8 alphanumeric

characters.
The same password should be entered twice at
each level for confirmation.

[Pan/Tilt Position] To select whether the current pan/tilt positions

are to be displayed in the control and
configuration windows. (This is ineffective with
the VN-C30U Ver. 2.)

[Cache Control] With a very small number of proxy servers that

caches cgi, the pan/tilt control may not function
correctly. In this case, inhibit the Cache operation
by checking the cache box.

[FTP Server Function] Set whether FTP Server is valid/invalid.

If this is set to valid, it will be possible to upload
various user HTML pages, GIF and JPEG image
files, etc. to this unit using common FTP client
software.
* Uploaded files will all be placed directly under

the “/user folder” directory.
Access from a web browser can be done by
inputting the URL such as http://192.168.0.2/
user/aaa.html
(When accessing “aaa.html” stored on FTP, the
“192.168.0.2” denotes the IP address of this
machine.)

* The FTP user name is fixed as “Administrator”.

For the FTP password, use the administrator
level password.

* When the “HTTP Viewing” is set to “Disable”

using the Setup Tool, it will not be able to
access the file uploaded with a Web browser.

CAUTION

• The allotted FTP user area is approximately 90 K bytes, however since
this unit’s file system is generated dynamically, the actual storable
capacity may be less than this in certain cases.

•Folders cannot be created on this FTP server. Only file upload/delete/
rename are possible.

[Default Page Set-up] If “invalid”, it will be set to the regular VN-C30U

Top Page.
If “valid”, the HTML file you set will be used as
the default page.

*Default Page refers to the page that is displayed when only the IP address

is specified.

ATTENTION

Even if the function is “valid”, if the HTML file specified here does not
exist then a message such as “404: Not Found” will be displayed by the
browser when “http://192.168.0.2/” is specified, so make sure that the
setting is made correctly.

[HTTP Port] It is possible to change the port number of the

HTTP Server on this unit to a number other than
the default port 80 to raise the level of security.
(Selectable range: 1-65535 excluding 20 and 21)
If the HTTP Port is changed, access from web
browser will be done as follows:
http://192.168.0.2:12345/ or http://

192.168.0.2:12345/index.html
(Example when Port 12345 is selected)
When you don’t know or forget the HTTP Port
number, use the provided Setup tool to check it.

[Default positioning] This enables setting the HTTP port automatically

in order to resume a specified position number
when the power is turned on or if the software is
reset. (It is necessary to register a position in
advance in the memory to enable this function.
Refer to page 19.)

Password protection

Access protection using a password is provided with the VN-C30U to
restrict other connecting browsers (users). The access protection function
provides three security levels, each of which is allowed to access the
kinds of pages as shown in the following table.
(For the configuration of the VN-C30U web pages, see page 14.)

Level Access Permission

User Image pages only.

Operator Web pages other than the configuration pages.

Administrator All web pages

CAUTION

•Never forget the current password for it cannot be canceled or changed
unless it matches the password set at the administrator level.

•Even when the user or operator level password is set, the password will
not be asked for unless the administrator level password is set.
