䢇 This product comes with a built-in AGC circuit. When using this product with AGC set to AMidB, AHighB or ASuperB, the sensitivity level increases when the image is dark, and the screen may appear grainy as a result.

However, this is not a malfunction.

䢇 When using this product with the white balance set to AATWB, the displayed color may differ slightly from the actual color according to the condition of the object due to the principle of the automatic tracking white balance circuit. This is not a malfunction.

䢇 The electronic shutter of this product is set to

A1/30B by default. For regions with a commercial power supply frequency of 50 Hz, switch to the flickerless mode during use under fluorescent lights (excluding inverter lighting equipment) to prevent flickers.

䢇 When the Black-and-white mode (VN-V26U) or Easy Day and Night mode (VN-V25U) is enabled, the image becomes black-and-white in a dark place. As the sensitivity level is increased in this case, the screen may appear grainy and more white spots may appear. When switching between color and black-and-white images, the brighter area on the screen is emphasized, which may reduce the visibility. However, this is not a malfunction.

䢇 If the power supply voltage is momentarily cut off or reduced due to lightning, turning on of the air conditioner’s power, etc., the image may be disrupted or noise interference may occur.

䢇 When using multicast, make use of a

IGMPv2-compliant network switch.

䢇 In the case of VN-V26U, the image and sound may not synchronize when playing back using built-in viewer. This is not a malfunction.

䢇 When VN-V26U is sending high bitrate, the image and sound can be paused during

Black-and-white mode changing. This is not a malfunction.

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.

● 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.

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.

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.

The maximum number of distributions varies with the bit rate settings as well as the client’s requested frame rate. Up to 20 streams can be distributed (including multicast). The total frame rate refers to the sum of these frame rates.

24

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:

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

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.

You can specify an estimated bit rate for both

VBR and CBR. (64 kbps - 8000 kbps)

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

VN-V26U.

(Example)

When VN-V26U sends out 2 audio streams and receives 1 audio stream, data volume will be as follows.

64 kbps x 3 = 192 kbps

VN-V25U_26U_EN.book Page 25 Friday, January 18, 2008 2:56 PM

Restrictions on the Number of

Distributions for VN-V25U/26U

The maximum number of distributions for

VN-V25U/26U 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.

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.

There may be a longer delay or interruption in the audio.

Network Delay

When the client acquires JPEG via TCP,

VN-V25U/26U 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.

Audio may be interrupted.

Decrease in the frame rate due to network delays can be eliminated by receiving data via multicast.

Network Jitter

When there is considerable network jitter, delay time may be prolonged and the image frame rate may drop. In the case of MPEG4, noise interference may occur and playback may fail.

Audio may be interrupted.

Packet Loss

When acquiring images from VN-V25U/26U via

TCP, packet loss may be recovered by TCP transmission. When there is considerable delay in the network, however, missing data may occur and the image frame rate may drop. In the case of MPEG4, noise interference may occur and playback may fail.

Audio may be interrupted.

When packet loss occurs during multicast sending from VN-V25U/26U, the image frame rate may drop. In the case of MPEG4, noise interference may occur and playback may fail.

Audio may be interrupted.

Setting the IP address for VN-V25U/26U

There are two methods to set the IP address for

VN-V25U/26U as follows.

(A) Assigning an IP address to VN-V25U/26U from the DHCP server

(B) Assigning a static IP address to VN-V25U/

26U

(A) Assigning an IP address from the

DHCP server

● 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.

● For details on IP addresses assigned to

VN-V25U/26U, consult your network administrator.

You can look up the IP address of VN-V25U/

26U using the search tool in the supplied

CD-ROM.

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.

(B) Assigning a static IP address

System configuration required for setting

IP address

The default setting for VN-V25U/26U is ADHCP

Enable B (DHCP client feature is turned on).

Upon starting up in LAN without DHCP server,

VN-V25U/26U starts running with the following

IP address after time out of DHCP.

IP address

Subnet mask

: 192.168.0.2

: 255.255.255.0

Default gateway : Nil

Note:

● 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.

Set up the computer for setting the IP address.

Minimum computer specifications for setting

OS : Windows XP (Professional or

Home Edition) (SP2)

Web browser : Internet Explorer

Version 6.0

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.

● The screen appears grainy at dark locations when the AGC feature is in use.

This feature is used to raise the sensitivity level by lengthening the exposure time.

You can specify the number of times by which the sensitivity level is to be increased automatically when the object becomes dark. When Ax32B is selected, the sensitivity is automatically and continuously increased to 32 times of the level when AOffB is selected. When the sensitivity level increases, the shutter speed slows down, and motion becomes unnatural.

When set to AOffB, [Sense Up] is disabled.

[Set values: Off, x2, x4, x8, x16, x32, x62]

Note:

● Upon raising the sensitivity level, the screen may appear grainy or white, or white defects may occur. However, this is not a malfunction.

● When [Sense Up] is set to a value other than AOffB, flickers occur under the light of fluorescent or mercury lamps. This is not a malfunction of the camera, but is due to principles related to [Sense Up].

● When the shutter is set to a value between 1/50 to 1/10000, set

[Sense Up] to AOffB.

For setting the priority of ALC (feature for maintaining the video level according to the brightness of the object). You can select whether to assign priority to the motion or picture quality when the object becomes dark.

Motion : Assigns priority to motion.

When the object becomes dark, priority is given to AGC

(automatic gain control), and therefore this is suitable for shooting fast-moving objects.

Quality : Assigns priority to picture quality.

When the object becomes dark, priority is given to the

[Sense Up] feature, and therefore this is suitable for shooting objects requiring a high picture quality.

E Frame Rate For setting the MPEG4 frame rate.

[Setting range: 1 fps - 30 fps]

F

I Frame Interval For setting the I-frame interval. MPEG4 starts encoding from the I-frame.

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 set the MPEG4 rate control mode to CBR (Constant

Bit Rate) or VBR (Variable Bit Rate).

CBR : Encoding is performed at a fixed bit rate regardless of the condition of the input video signals. Enables easy forecast of the bit rate.

VBR : Changes the bit rate according to the condition of the input video signals. Picture quality is stable, but forecast of the bit rate is difficult.

For selecting whether to assign priority to the frame rate or picture quality during MPEG4 encoding.

FPS : Assigns priority to frame rate. Select this setting to enable smooth monitoring of motion images.

Quality : Assigns priority to picture quality.

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, this will be denoted as “www.victor.co.jp” in FQDN.

For setting the FTP environment when [FTP] is specified as an action on the

Alarm page. This is common with the FTP environment when using the periodic FTP on 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 corresponding directory name in [Directory].

Delimit the directory using “/”.

Example: subdir1/subdir2

Destination directory of FTP transfer will be dependent on the FTP server if

“/” is added at the beginning.

Setting [Periodic FTP] to AOnB enables transfer of the latest JPEG images to the FTP server at regular intervals. Specify the interval in seconds for

[Periodic FTP Interval].

File name: Select a type from the two types of periodic FTP file names.

When AAutoB is selected, images are generated from the year, month, day, hour, minute, second, and number.

Example: 20071114161032-001-2.jpg

When AManualB is selected, you can select a file name generation method from the following.

● File name containing only the character string entered in [User-definedname]

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.

When a multicast address is specified and AallowB is selected, VN-V25U/

26U will only accept transmission to this multicast address and deny transmission to multicast addresses that are not stated in the [IP Address] field.

Caution:

● Note that when AallowB is selected and all IP address fields are left blank, JPEG/MPEG4 acquisition by all IP addresses will be denied.

Restrictions are not imposed on access to the Web Settings page.

Additionally, VN-V25U/26U will also deny access when instructions for transmission to the specified IP address are sent via API.

Note:

● To specify a specific IP address range, enter a combination of the IP address and subnet mask in the [IP Address] field.

● Define the subnet mask using a length between 8 ~ 30 bits.

For example, a range between 192.168.0.0 to 192.168.0.255 is denoted as 192.168.0.0/

24 ([IP Address]/[bit length of subnet mask]).

The web page of VN-V25U/

26U cannot be displayed

The built-in viewer cannot be installed

Authentication by Verisign appears during installation of the built-in viewer

TCP images cannot be played back

Causes and Countermeasures

● DHCP is AEnableB in default settings. IP address will be provided from DHCP server.

● If there is no DHCP server, VN-V25U/26U will start using default IP address, 192.168.0.2, and default subnet mask, 255.255.255.0.

● Search tool in attached CD-ROM is available to find VN-V25U/26U from a PC in the same LAN.

Check the Internet Explorer settings.

When a proxy server is in use, configure the proxy server settings of the Internet Explorer accordingly.

Check the Internet Explorer settings.

The built-in viewer consists of a software component called ActiveX.

The ActiveX is usually installed when the built-in viewer is used for the first time. However, installation may be rejected depending on the Anti-virus software settings. In this case, change the settings of the Anti-virus software before installing the built-in viewer.

Verisign’s electronic signature is stored in the builtin viewer.

For computers with a network environment that is connected to the Internet, the authenticity of the viewer can be verified via authentication by

Verisign.

The built-in viewer consists of a software component called ActiveX.

The ActiveX is usually installed when the built-in viewer is used for the first time. However, installation may be rejected depending on the Anti-virus software settings. In this case, change the settings of the Anti-virus software before installing the built-in viewer.

The maximum number of images that can be sent by

VN-V25U/26U via TCP is 20, and up to 20 built-in viewers can be connected to each VN-V25U/26U unit.
