Insufficient network bandwidth
Network Requirements
When there is insufficient bandwidth, the number
of JPEG frames (frame rate) that the client can
acquire will decrease.
●
Ensure that there is sufficient network bandwidth
for the data volume to be sent out by VN-C20.
● Data volume to be sent by VN-C20 varies
with the settings and number of distributions.
The maximum bit rate from VN-C20 is about 9 Mbps.
●
Network Delay
Estimation of total bit rate
When the client acquires JPEG via TCP, VN-C20 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.
Network delay due to a drop in frame rate can be
eliminated by receiving data via multicast.
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.
Network Jitter
When there is considerable network jitter, delay
time may be prolonged and the image frame rate
may drop.

When acquiring images from VN-C20 via TCP,
packet loss may be recovered by resending from
TCP. When there is considerable delay during
resending, however, missing data may occur and
the image frame rate may drop.
When packet loss occurs during multicast sending
from VN-C20, the image frame rate may drop.

VN-C20 uses the protocols and port numbers
listed below. Ensure that these ports are allowed
through the firewall when a firewall is to be
installed.
VN-C20 accepts requests from up to a maximum of
5 clients. In addition, it also allows transmission of 1
multicast stream. The total frame rate refers to the
sum of these frame rates.
For example, when 10 fps is requested by 2
clients, and in addition multicast is transmitted at
a rate of 10 fps, the total frame rate will be:

Setting IP address with the default VN-
C20 settings
VN-C20 is set to ADHCP EnableB(the DHCP
client function is ON) by default. Upon starting
up in LAN without DHCP server, VN-C20 starts
running with the following IP address after time
out of DHCP.
There are 2 methods to set the IP address when
VN-C20 is in its default settings.
(A) Assigning an IP address to VN-C20 from
the DHCP server
IP address
: 192.168.0.2
Subnet mask
: 255.255.255.0
(B) Assigning a static IP address to VN-C20
Default gateway : None
Note:
Ⅵ (A) Assigning an IP address from the
DHCP server
● To set a static IP address for VN-C20,
connect VN-C20, switching hub and
computer for setting using a straight LAN
cable of Category 5 and above.
● VN-C20 is set toADHCP EnableB (the DHCP
client function is ON) by default. To assign an
IP address from DHCP server, connect VN-
C20 to LAN with DHCP server, and turn on
VN-C20. Allowing the DHCP server to assign
the same IP address to VN-C20 every time
eases access toVN-C20.
ⅷ Set up the computer for setting the IP
address.
● Minimum computer specifications for setting
● For details on IP addresses assigned to VN-
C20, please consult your network
administrator.
● You can look up the IP address of VN-C20

Caution:
● When setting the IP address for VN-C20, do
so by using a network that is made up only of
VN-C20, the computer for setting and the
switching hub.
● Using a hub connected to other network
devices can cause problems.
Caution:
● Set the DHCP server such that the IP
address assigned to MAC address of VN-
C20 from the DHCP server is the same each
time.Connection may fail if the above setting
is not performed.

AMail
For setting the mail environment when [Mail] is specified as an action of the
Alarm page.
[SMTP] and [POP] can be used. Configure only the SMTP settings in usual
circumstances.
Configure the POP settings as well if [POP before SMTP] is enabled. In
addition, if FQDN is set for [SMTP Server], etc., configure also the DNS
server settings on the [Basic] page.(A Page 44)
Note:
What is FQDN (Fully Qualified Domain Name)?
This is a fully qualified domain name that indicates a notation method of
describing the entire host or domain name on the TCP/IP network without
abbreviating.
For example, if the host name is www and the domain name is victor.co.jp,
BFTP
For setting the FTP environment when [FTP] is specified as an action of the
Alarm page.This is common with the FTP environment when using the
regular FTP within this page.
When [Directory] is left blank, FTP transfer will be performed to the home
directory of the FTP server. To enable FTP transfer to a directory below the
home directory, set the directory name in [Directory].
Delimit the directory using A/B.
Example: subdir1/subdir2
Destination directory of FTP transfer will be dependent on the FTP server if
A/B is added at the beginning.
Setting [Periodic FTP] to AOnB enables transfer of the latest images to the
FTP server at regular intervals. Specify the interval in units of seconds under
[Periodic FTP Interval]. Select a type from the two types of regular FTP file
names. When Automatic is selected, images are generated from the year,
month, day, hour, minute, second, and number.
Example: 20051114161032-001-2.jpg
When Custom is selected, images are generated from the user-defined
character string, year, month, day, hour, minute, second, and number.
Example: Camera1_20051114161032001.jpg
[Frame Rate] is constrained by the frame rate as set on the [Encoding] page.
(A Page 34)
The actual frame rate used for transmission will be the upper limit on the
[Encoding] page even if a value that is larger than the frame rate in the
[Encoding] page is specified. The upper limits of [Before Trigger] and [After
Trigger] are determined by settings on the [Encoding] page. In addition,
[Frame Rate] is in a trade-off relationship with [Before Trigger] and [After
Trigger]. 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 are the action number, and the following 14 digits denote the
year, month, day, hour, minute and second.
The 3 digits after the first hyphen is the number of the series of JPEG files to
be sent via that FTP. The first file is numbered A000B. The last digit denotes
the trigger flag. This is displayed as A1B only for the JPEG file during a trigger
input, and as A0B if otherwise.

EFrame Rate
For selecting the acquisition frame rate of the viewer.
In the case of a 1-to-1 connection between VN-C20 and the viewer, it is
recommended that the frame rate of the viewer and VN-C20 be set to the
same value. To play back multiple viewers at different frame rates, set the
frame rate accordingly at the individual viewer.
The frame rate set at the VN-C20 unit will be the upper limit to the
acquisition frame rate of the viewer.
For example, when VN-C20 is set to A15 fpsB, transmission will only be
possible at A15 fpsB even when the client requests for A30 fpsB.
Alternatively, when VN-C20 is set to A15 fpsB and A10 fpsB is requested by
the client, data will be sent at 7.5 fps to enable transmission at even
intervals.
When the frame rate set is smaller than that at the VN-C20 unit, the
frame rate during transmission from VN-C20 decreases 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-C20
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
computer on which the viewer is running.
Caution:
● This is different from the frame rate setting at the VN-C20 unit.
Set to a rate such that the CPU burden of the computer does not
exceed 80%. When the CPU is overloaded, the computer may not
function properly.
FTime Display Format Select the format for displaying time.
YYYY,MM,DD denote year, month and day respectively while HH,MM,SS
denote hour, minute and second respectively.
GStream
For selecting the protocol when the viewer acquires data from VN-C20.
When AHTTPB is selected, recovery will be performed via resending
viewers when AMulticastB is selected.
Additionally, start multicast sending on the Streaming page of the VN-
C20 unit when playing back via multicast.
Caution:
● When the built-in viewer is launched with AMulticastB specified, a
Windows firewall warning may be displayed. In this case, select
AUnblockB and proceed.
● If ABlockB is selected, the Windows firewall will block the multicast
streams and playback of multicast at the viewer will fail.
H
Multicast Address / Port For specifying the multicast address and port number.
This is enabled only when AMulticastB is selected for the [Stream] item.
Specify the same value as the parameter that is set on the [Streaming]
page of VN-C20. (A Page 46)
