Mounting to the Housing  
Warning  
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.)  
Mount the fall prevention wire using the  
black screw at the rear of the camera unit.

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. 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.  
Data volume to be sent by VN-V25U varies  
with the settings and number of distributions.  
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  
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.  
Estimation of Total Bit Rate  
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.  
The total JPEG bit rate from VN-V25U is  
determined by the VN-V25U settings, number of  
clients, and the client’s requested number of  
frames. The total MPEG4 bit rate from VN-V25U  
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.  
Restrictions on the Number of  
Distributions for VN-V25U  
The maximum number of distributions for  
VN-V25U is determined by the settings as well  
as requirements from the client.  
When only JPEG images are distributed, the  
maximum number of distributions is determined  
based on the highest bit rate within the stream.  
When a distribution request that exceeds the  
maximum number of distributions is received,  
this request is denied. For example, if Client A  
requests for and receives data at 1 Mbps, while  
Client B requests for and receives data at  
5 Mbps, the maximum number of distributions is  
4 streams according to the table below.

List of Protocols and Port Numbers  
Used by VN-V25U  
When both JPEG and MPEG4 images are

clients for JPEG and MPEG4 respectively is  
possible. However, distribution requests that  
exceed a total bit rate of 20 Mbps will be denied.

Insufficient network bandwidth  
When there is insufficient bandwidth, the  
number of JPEG frames (frame rate) that the  
client can acquire will decrease. Delay will also  
occur in the distribution of images. In the case of  
MPEG4, noise interference may occur and  
playback may fail.

Network Delay  
When the client acquires JPEG via TCP,  
VN-V25U will send out data while checking the  
ACK from the client at the same time. For  
networks with considerable delay, data cannot  
be sent out until ACK is received, and therefore  
the frame rate will drop. In the case of MPEG4,  
noise interference may occur and playback may  
fail.  
Decrease in the frame rate due to network delays  
can be eliminated by receiving data via multicast.
