Warning
Mounting to the Housing
Using the Inner Tripod Base
● Special attention is required when mounting
the camera to a wall or ceiling. Users
should get professional contractors to
perform mounting operations instead of
doing it themselves. Failure to do so may
cause the camera to fall off and result in
injuries or accidents.
● When mounting the camera to a fixer or
rotating platform, ensure that the camera is
firmly mounted by using the anti-rotation
holes to prevent it from falling off.
This product comes with an inner tripod base at
the bottom surface. You can use the inner tripod
base by removing the camera mounting bracket
that is attached to the bottom surface. Mount this
product to the miniature housing using the screw
hole of the inner tripod base.
● To prevent the camera from falling off,
ensure that it is connected to a firm place
(ceiling slab or channel) using a fall
prevention wire.
● Pay also careful attention to the length,
strength, wiring, and material (insulating
properties) of the fall prevention wire to be
used. The length used should be as short
as possible within the permissible range of
the mounting length. The wire should be
strong enough to withstand the total weight
of this product and the fixer. (Pay also
attention to the finishing at the end of the
wire.)
Inner Tripod Base
● Mount the fall prevention wire using the
black screw at the rear of the camera unit.
● Designated screw for fastening of fall

For example, when 10 fps is requested by two
clients, and in addition, multicast is transmitted
at a rate of 10 fps, the total frame rate will be:
Network Requirements
●
Ensure that there is sufficient network
bandwidth for the data volume to be sent out
by VN-V25U/26U. Do not send multicast
stream that exceeds the bandwidth. If the
entire bandwidth is used by the multicast
stream, control of this camera via the network
may fail.
10 + 10 + 10 = 30 fps
If the JPEG file size per frame is 30 KB, then the
total bit rate will be:
30 KB x 30 fps = 900 KB/s = Approx. 7.2 Mbps
Bit Rate of MPEG4 Stream
●
●
Data volume to be sent by VN-V25U/26U varies
with the settings and number of distributions.
The maximum bit rate for transmission is
about 20 Mbps.
You can select either the Variable Bit Rate
(VBR) or Constant Bit Rate (CBR) system for
MPEG4 stream.
When the VBR system is selected, the bit rate
varies according to the condition of the input video
signals. The VBR system delivers a stable picture
quality, but forecast of the bit rate is difficult.
When the CBR system is selected, encoding is
performed at a fixed bit rate regardless of the
condition of the input video signals. The picture
quality varies under the CBR system, but the bit
rate can be easily forecast.
Estimation of Total Bit Rate
The total JPEG bit rate from VN-V25U/26U is
determined by the VN-V25U/26U settings,
number of clients, and the client’s requested
number of frames. The total MPEG4 bit rate
from VN-V25U/26U is determined by the number
of distributions. Develop a design upon taking
the above into consideration.
You can specify an estimated bit rate for both
VBR and CBR. (64 kbps - 8000 kbps)
Bit Rate of JPEG Stream
The JPEG file size per frame varies with the
encoding settings as well as input video signals.
The following table may be used as a reference.
When VFS is selected, the quantization table
during JPEG encoding will be maintained, and the
file size will increase/decrease according to the
input signals. When AFS is selected, encoding will
be performed such that the target file size is the
average size of multiple JPEG images.
Bit Rate of Audio (VN-V26U only)
Up to 2 audio data streams can be sent by VN-
V26U.
Only 1 audio data stream can be recieved. Data
volume for 1 audio stream is 64 kbps. Audio data
volume may be calculated using the following
formula.
64 kbps x no. of streams
The number of streams is the total number of
streams sent via TCP (number of clients), streams
sent via multicast, and stream received by

When both JPEG and MPEG4 images are
distributed simultaneously, distribution up to two
clients for JPEG and MPEG4 respectively is
possible. However, distribution requests that
exceed a total bit rate of 20 Mbps will be denied.

Note:
DHCP server
● To set a static IP address for VN-V25U/26U,
connect VN-V25U/26U, the switching hub
and the computer for setting using a straight
LAN cable of Category 5 and above.
● VN-V25U/26U is set to ADHCP EnableB (the
DHCP client feature is on) by default. To
assign an IP address from the DHCP server,
connect VN-V25U/26U to LAN with DHCP
server, and turn on VN-V25U/26U. Allowing
the DHCP server to assign the same IP
address to VN-V25U/26U every time eases
access to VN-V25U/26U.
ⅷ Set up the computer for setting the IP
address.
● Minimum computer specifications for
setting
● For details on IP addresses assigned to
VN-V25U/26U, consult your network
administrator.
OS

Home Edition) (SP2)
You can look up the IP address of VN-V25U/
26U using the search tool in the supplied
CD-ROM.
Web browser : Internet Explorer
Version 6.0
For details, please refer to AReadmeB file in
the CD-ROM.
Caution:
● Set the DHCP server such that the same IP
address is always assigned to the MAC
address of VN-V25U/26U by the DHCP
server. Connection may fail if the above
setting is not performed.
Caution:
● When setting the IP address for VN-V25U/
26U, do so by using a network that is made
up only of VN-V25U/26U, the computer for
setting and the switching hub.
● Using a hub connected to other network
devices or networks via a LAN cable for
setting can cause problems.

Shortening the interval stabilizes the picture quality even when there are
rapid changes in the video image. However, the picture quality for images
with little change will deteriorate. In addition, when multicast packet loss
occurs, the time interval required to restore the image is shorter.
[Set values: 30, 60, 90, 120, 150]
G Priority
For selecting whether to assign priority to the frame rate or picture quality
during MPEG4 encoding.
FPS

● File name containing only the character string entered in [User-defined-
name]
Example: Camera1.jpg
● File name with the year, month, day, hour, minute, and second added to
[User-defined-name]
Example: Camera1_20071114161032001.jpg
The name of the file to be transmitted via FTP is made up of the action
number, year, month, day, hour, minute, second, number and trigger flag.
Example: 01-20070711152904-001-0.jpg
The first two digits are the action number, and the following 14 digits denote
the year, month, day, hour, minute and second.
The three digits after the first hyphen is the number of the series of JPEG
files to be sent via the FTP. The number starts from “000”. The last digit
denotes the trigger flag. This is displayed as “1” only for the JPEG file during
a trigger input, and as “0” if otherwise.
