2. Requirements for network using VN-E4
Ⅵ2-1 Network Bandwidth
Ensure that there is sufficient network bandwidth for the data volume to be transmitted by VN-E4. Data volume to be transmitted
by VN-E4 varies with the number of image or audio distributions.
● Data volume of images
VN-E4 enables creation of up to 8 different types of images.

VN-E4 allows distribution of each image to multiple destinations. Data of image to be transmitted by VN-E4 is therefore the
aggregate total of all these data.
Data volume of No. 1 L no. of distributions + data volume of No. 2 L no. of distributions +...+ data volume of No. 8 L no. of
distributions
The number of distributions shall be the total number of stream transmissions via TCP (number of clients) and multicast.
(Example)
Data volume will be calculated according to the formula below when 3 streams of No. 1 are sent.
JPEG file size per frame L frame rate L 3
If the JPEG file size per frame is 30 KB and frame rate is 30 fps, then data volume will be as follows.
30 KB L 30 fps L 3 = 2700 KB/sec = Approx. 21 Mbps
The JPEG file size per frame varies with the parameter set as well as input video signals. The following table may be used as a
reference.

● Audio data volume
Audio data transmitted by VN-E4 is at 64 kbps per stream. Audio data volume may be calculated using the following formula.
64 kbps L 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 VN-E4.
(Example)
When VN-E4 sends out 2 audio streams and receives 1 audio stream, data volume will be as follows.
64 kbps L 3 = 192 kbps
NOTE:
When there is insufficient network bandwidth, the number of JPEG frames (frame rate) that may be acquired by the client will
decrease.
In addition, delay time will be prolonged and interruptions will also occur in the audio data.

Download from Www.Somanuals.com. All Manuals Search And Download.
Ⅵ2-2 Network Delay
When the client acquires JPEG or audio via TCP, VN-E4 will be 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.
To operate VN-E4 and its built-in viewer using the factory settings, the frame rate will drop below 120 fps if the round trip time
exceeds 4 msec. Enlarging the window scale of the PC on which the built-in viewer is running may extend the round trip time for
which frame rate deteriorates to 20 msec. Refer to the section on A7. TroubleshootingB in AOthersB for details on the window scale.
Drop of frame rate by network delay can be eliminated by using multicast.
Ⅵ2-3 Network Jitter
When there is considerable network jitter, delay time may be prolonged, frame rate may drop and audio sound may be
interrupted.
There are 3 types of buffer that may be chosen for the built-in viewer, namely 0.3, 0.6 and 1.0 second. Influences of jitter may be
reduced by setting to a larger value. In this case, however, delay time will be prolonged.
Ⅵ2-4 Packet Loss
When acquiring images/audio from VN-E4 via TCP, packet loss may be recovered by resending from TCP. When there is
considerable delay during resending, however, image frame rate may drop and audio sound may be interrupted.
When packet loss occurs during multicast sending from VN-E4, image frame rate may drop and audio sound maybe interrupted.
Ⅵ2-5 Use of Multicast
Make use of a network that supports IGMP if multicast is to be used. When a network that does not support IGMP or multicast
routing is used, multicast data that is sent out from VN-E4 may not reach the recipient and playback may fail.

Perform following procedures to find out the IP address of VN-E4.
1. Configuration for looking up IP address
Set up a PC with the network monitor software installed on it. The network monitor software will capture and look up incoming
packets at the PC. An example of free network monitor software that may be obtained from the Internet is Ethereal.
Connect VN-E4, the switching hub and PC using a straight LAN cable of Category 5 and above. (Do not connect the DHCP
server to the switching hub.)
2. Capturing packets sent by VN-E4
Launch the network monitor software on the PC and start capturing.
Supply power to VN-E4 using the AC adaptor. Depending on the settings, the amount of time required for VN-E4 to start up may
vary from about 1 to 2 minutes. VN-E4 will start packet transmission during this interval, and capturing will end in about 2 minutes.
3. Looking up captured packets
● If ARP request is sent first by VN-E4
If the following ARP request is sent first by VN-E4, then the destination IP address of this packet will be the IP address of
VN-E4. (In this case, the subnet mask of VN-E4 is unknown.)
Packet type: ARP request
Source IP address: 100.100.254.169
This ARP request packet is used to check whether there are devices that possess a duplicate IP address with VN-E4. In this
case, ADHCPB and APPPoEB of VN-E4 are set to AOffB.
● If the DHCP Discover packet is sent first by VN-E4
The DHCP client function of VN-E4 is set to ON. In a LAN environment without a DHCP server, the DHCP will time out in
about 2 minutes after the power is turned on, and VN-E4 will be started up using the following IP address.
IP address 192.168.0.2
Subnet mask 255.255.255.0
Default gateway 192.168.0.254
● If the following broadcast packet is sent first by VN-E4
Destination MAC address 0xFFFFFFFFFFFF
Ethernet Type 0x8863
The APPPoEB of VN-E4 is set to AOnB. In a LAN environment without a PPPoE server, it will time out in about 2 minutes after
the power is turned on, and VN-E4 will be started up using the following IP address.
IP address 192.168.0.2
Subnet mask 255.255.255.0
Default gateway 192.168.0.254
4. IP address setting on PC
The subnet mask of VN-E4 is unknown when methods 1. to 3. are used to look up the IP address, and there is a possibility
that this may be 255.255.255.254.
Set the IP address of the PC such that it is in the same segment with VN-E4.
(Example 1) When the IP address of VN-E4 is 10.1.2.2
By setting the PC’s IP address to 10.1.2.3 and the subnet mask to 255.255.255.0, they will be in the same segment and
communication will be enabled even if the subnet mask of VN-E4 is 255.255.255.254.
(Example 2) When the IP address of VN-E4 is 10.1.2.3
By setting the PC’s IP address to 10.1.2.2 and the subnet mask to 255.255.255.0, they will be in the same segment and
communication will be enabled even if the subnet mask of VN-E4 is 255.255.255.254.
Whether communication is enabled may be determined by sending a Ping from the PC to the IP address of VN-E4.
For procedures on changing settings of VN-E4 via Internet Explorer on the PC, refer to A5. Setting Using Internet ExplorerB.

A
Encode Number
Up to 8 types of encoding are possible using different combinations of the input channel and
frame size. Turn on the check box for items to be used. Deselect unnecessary items to enable
effective allocation of the processing capacity of VN-E4.
B
Quality
For specifying the rate control mode and target file size.
When A1-high-B to A7-high-B is selected, the quantization table of JPEG encoding is fixed and the
file size will increase/decrease according to the input signals. Default value of each option is
displayed in the target file size. Be careful when recording JPEG data to a recorder with limited
recording capacity, as file sizes may increase or decrease, so the maximum recording time may
be changed (When AAverage File SizeB or AConstant File SizeB is selected, input of target file size
will be enabled.)
WhenAAverage File SizeB is selected, encoding is performed such that average file size of
multiple JPEG images becomes the target file size.
WhenAConstant File SizeB is selected, encoding is performed such that each JPEG file size
becomes the target file size. When AConstant File SizeB is selected, the processing load of
VN-E4 is heavy and the maximum frame rate becomes a quarter of the maximum frame rate in
other rate control modes
C
Frame Rate
For specifying the number of frames to encode per second. VN-E4 is limited in its processing
capacity and the specified frame rate may not be realized depending on the settings of
AEncode NumberB and AQualityB.
In particular, when AConstant File SizeB is selected or when the target file size is set to a large
value, the upper limit of AFrame RateB will be lowered.
An example of settings for which 120 fps (VN-E4U) or 100 fps (VN-E4E) can be realized is as
follows.
Encoding
Quality
: 4 VGA set to ON
: AAverage File SizeB selected and set to A24KBB

Interpolate
When AInterpolateB is off, video frame with 480 horizontal lines is encoded to JPEG. When
AInterpolateB is on, video field with 240 horizontal lines is interpoleted to 480 horizontal lines, and
encoded to JPEG. To get high resolution, AOffB is recommended. To avoid jaggy image caused
by fast moving objects, AOnB is recommended.

AFrame RateB will be constrained by the frame rate as set on the AEncodingB page. The actual
frame rate used for transmission will be the upper limit on the AEncodingB page even if a value
that is larger than the frame rate in the AEncodingB page is specified. The upper limits of ABefore
TriggerB and AAfter TriggerB are determined by settings on the AEncodingB page. In addition,
AFrame RateB is in a trade-off relationship with ABefore TriggerB and AAfter TriggerB. In the case of
a combination such that the input value cannot be realized, adjustments will be automatically
made on the item that is not specified.
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: 01-20050711152904-001-0.jpg
The first 2 digits indicate the action number. Next 14 digits after first hyphen indicate the year,
month, day, hour, minute and second. The 3 digits after the second hyphen is the number of the
series of JPEG files to be sent via that FTP. The first file is numbered 000. The last digit denotes
the trigger flag. 0 is assigned to JPEG files before and after a trigger and 1 for the file when

Frame Rate Selection For selecting the acquisition frame rate of the viewer.
List
The frame rate set at the VN-E4 unit will be the upper limit to which the viewer can acquire. For
example, when VN-E4 is set to A15 fpsB, transmission will only be possible at 15 fps even when
the client requests for 30 fps. Alternatively, when VN-E4 is set to A15 fpsB and 10 fps is requested
by the client, data will be sent at 7.5 fps to enable transmission at even intervals. In the case of a
1-to-1 connection between VN-E4 and the viewer, it is recommended that the frame rate of the
viewer and VN-E4 be set to the same value. To play back multiple viewers at different frame
rates, set the frame rate accordingly at the individual viewer.
NOTES:
● When the frame rate set is smaller than that at the VN-E4 unit, this will be reflected in the
frame rate during transmission from VN-E4 when acquisition is performed via HTTP.
● When acquisition is performed via multicast, data volume will not decrease even when a
frame rate that is smaller than that at the VN-E4 unit is set, and the built-in viewer will play
back images while skipping frames.
●
Selecting a large frame rate will increase the processing load of the PC on which the viewer is running.

Refer to ASTART-UP GUIDEB to check the Internet Explorer settings.
The built-in viewer cannot be
installed
Refer to ASTART-UP GUIDEB to check the Internet Explorer settings.
Installation of the built-in viewer may fail when an anti-virus software is installed on the PC.
Install the built-in viewer on a PC that does not have such anti-virus software installed.
An anti-virus software warning
A warning message may appear when an anti-virus software is installed on the PC. To
message appears upon starting prevent the warning message from appearing, install the built-in viewer on a PC that does
up the built-in viewer
not have such anti-virus software installed.
Authentication by Verisign
appears upon installing the
built-in viewer.
Verisign’s electronic signature is stored in the built-in viewer. For PCs that are connected to
WEB, the authenticity of the viewer can be verified by Verisign authentication server.
TCP image/audio cannot be
played back
Check the total bit rate and number of distributions on the AOperationB page of VN-E4.
Maximum bitrate from VN-E4 is 40 Mbps. New requests for distribution will be denied upon
exceeding 40 Mbps.
VN-E4 allows TCP transmission of up to 10 streams of JPEG or audio data. For example,
when acquiring 4 JPEG and 1 audio streams via TCP using the built-in viewer, a maximum
of 2 built-in viewers may be connected to one VN-E4. Make use of multicast for monitoring
by multiple viewers. VN-E4 allows multicast transmission of up to 10 streams.
Multicast image/audio cannot
be played back
Start multicast transmission manually from the AStreamingB page of VN-E4.
In the case of multicast reception at the built-in viewer, check that the multicast address
and port number of the built-in viewer settings coincide with those on the AStreamingB page
of VN-E4.
Make use of a network that supports IGMP for multicast transmission.
The frame rate of JPEG is low
Noise is heard in the audio
Check the settings on the AEncodingB page of the VN-E4 unit. Check the built-in viewer
settings as well when a built-in viewer is in use.
Frame rate will be constrained when the network bandwidth is narrow.
Frame rate will be constrained when there is prolonged network delay or when the data
volume sent from VN-E4 is high. When this occurs, enlarge the window scale of the PC on
which the viewer is running. The window scale can be altered by changing the Windows
registry. Refer to Windows manual on procedures to change the Windows registry.
Narrow network bandwidth or considerable jitter may cause failure of smooth transmission.
This can be remedied by reducing the transmission volume. Transmission volume can be
lowered by reducing the number of channels, frame rate and frame size of JPEG data to
acquire.
Audio output from the PC will pass through Windows’ sample rate conversion function. For
some PCs, sample rate conversion may not be performed properly and interruptions may
occur in the audio sound. To resolve this problem, perform the following procedures to
change the Windows settings.
Go to AControl PanelB - ASounds and Audio DevicesB - AAudioB Tab - AAdvancedB -
APerformanceB Tab, and change ASample rate conversion qualityB from ABestB to AGoodB.
For some PCs, sound quality may deteriorate when the Windows OS plays back audio files
such as beep sounds with ASample rate conversion qualityB set to AGoodB.
Sound Blaster is recommended for use with this product.
A white zone appears in the
built-in viewer.
For some PCs, a part of the Internet Explorer graphics may not appear and is left white
when the following IE setting is performed.
ARight-click on DesktopB - APropertiesB - ASettingsB - AAdvancedB - AGeneralB - ADPI settingB,
and selecting ALarge sizeB or ACustom sizeB
When this occurs, graphics will be properly restored by selecting ANomal sizeB instead of
ALarge sizeB and ACustom sizeB.
