What is PoE (Power over Ethernet)?  
This is a function that enables operation of a  
LAN equipment without a power cable by  
supplying power simultaneously with the data  
using a LAN cable.  
When electricity is supplied to the camera,  
the power indicator lights up for a moment,  
starts blinking during startup, and lights up  
when startup is complete.  
Caution:  
Make sure to select only one mode of  
electrical supply. Connecting the power cord  
and the LAN cable for the PoE at the same  
time may result in failure or malfunction of the  
camera.

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:

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

Note:  
(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.  
Set up the computer for setting the IP  
address.

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

Select either VGA (640 
ן
 480) or QVGA (320 
ן
 240) as the frame size.  
For specifying the rate control mode and target file size.  
When AVFS1B to AVFS7B is selected, the quantization table during JPEG  
encoding will be maintained and the file size will increase/decrease  
according to the input signals. Stipulated values will be displayed for the  
target file size. When recording JPEG data to a recorder with limited  
capacity, pay attention when making a selection for this item as the  
maximum recording time varies accordingly when the file size increases/  
decreases. In this case, encoding is performed such that the average size of  
multiple JPEG images becomes the target file size when AAFSB is  
selected.(When AAFSB is selected, input of target file size will be enabled.)  
CFPS  
For specifying the number of frames to encode per second. VN-C20 is  
limited in its processing capacity and the specified frame rate may not be  
realized depending on the settings of [Frame Size] and [Quality/Size]. In  
particular, when the specified target file size is large, the upper limit of the  
frame rate drops.  
An example of settings for which a total frame rate of 30 fps can be realized  
is as follows.

(The maximum bit rate from VN-C20 is about 9 Mbps.)  
DFine  
Each video frame is made up of 2 fields.  
When Fine is set to AOnB, the 2 fields can be used as is.  
When Fine is set to AOffB, the frame is formed using only one of the fields,  
hence preventing the image from blurring even when the object is moving.

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.

via TCP and noise occurs due to losses during packet reception via  
multicast.To use this feature with inversion set to AOnB, make sure that  
you use a computer with adequate performance, or reduce the  
processing load by adjusting the [Encoding] settings (file size, frame rate,

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  
when packet loss occurs. VN-C20 may be monitored using multiple  
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.
