Recording the type and time of alarm occurrence at the PC. Remote control of some external devices using the pass-through feature of VN-E4.

Preparation (continued)

2. Requirements for network using VN-E4

䡵2-1 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.

Input CH Frame Size

No. 1 CH1 VGA

No. 2 CH1 QVGA

No. 3 CH2 VGA

No. 4 CH2 QVGA

No. 5 CH3 VGA

No. 6 CH3 QVGA

No. 7 CH4 VGA

No. 8 CH4 QVGA

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.

Picture Quality Control Method VGA File Size QVGA File Size

1 (High) 80 KB 27 KB

2 60 KB 20 KB

3 40 KB 13 KB

VFS (Variable File Size)

AFS (Average File Size) CFS (Constant File Size)

● 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.

Preparation (continued)

䡵2-2 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.

䡵2-3 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.

䡵2-4 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.

䡵2-5 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.

3. IP Address Setting

䡵3-1 VN-E4 with Factory Default Settings

Refer to

START-UP GUIDE

on procedures for setting the IP address when VN-E4 is in the factory default settings.

䡵3-2 VN-E4 for which IP address is known

When the IP address of VN-E4 is known, it can be changed by accessing the built-in web page of VN-E4 via the PC’s Internet Explorer. See A5. Setting Using Internet ExplorerB.

䡵3-3 When IP address of VN-E4 is unknown

When IP address of VN-E4 is unknown, there are 3 methods to know IP address.

a) Use the search tool

The search tool in attached CD-ROM is available to know IP address of VN-E4. Refer readme file of the tool for detailed information.

b) Initialize VN-E4

Pushing [RESET] button on rear panel over 5 seconds initializes VN-E4 to factory default setting.

c) Capture packets on network

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.

This page is for setting JPEG encoding parameters.

A B C D

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 : 4 VGA set to ON Quality : AAverage File SizeB selected and set to A24KBB

Frame Rate : A30B(VN-E4U), A25B(VN-E4E)

The unit will function as follows if the frame rate is altered when data distribution is in progress.

on the AInputB page of the VN-E4 unit.

For selecting the acquisition frame rate of the viewer. 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. Set to a value such that the load of the PC on which the viewer is running does not exceed 80 %.

When AMakeB is selected, the AAlarmB button will light up when Make occurs in the alarm input of VN-E4. When ABreakB is selected, the AAlarmB button will light up when Break occurs in the alarm input of VN-E4.

For selecting the protocol when the viewer acquires data from VN-E4. When HTTP is selected, packet loss can be recovered by HTTP though number of clients is limited. Maximum number of HTTP streams is 10. When AMulticastB is selected, multiple viewers can monitor VN-E4 though packet loss causes noise or skip of data. Additionally, start multicast sending on the AStreamingB of the VN-E4 unit when playing back via AMulticastB. When the viewer is launched with AMulticastB specified, a Windows firewall warning may be displayed. When this occurs, proceed upon selecting “Unblock”. If “Block” is selected, the Windows firewall will block the multicast streams and playback of AMulticastB at the viewer will fail.

For specifying the multicast address and port number for 4 channel JPEG and audio. This is enabled only when AMulticastB is selected in the AStreamB selection. Specify the same value as the parameter that is set on the AStreamingB page of VN-E4.

Select AOnB to enable audio monitoring of VN-E4 using the viewer. The viewer will not acquire audio from VN-E4 when AOffB is selected.

For selecting the buffer volume of the viewer. To shorten the delay time, select a small buffer. To ensure stable playback on a network with unstable bandwidth and jitter, select a large buffer.

Upon registering the password, features of the ASpeech OnB and AControl CH1-CH4B buttons will be available for use.

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.

A warning message may appear when an anti-virus software is installed on the PC. To prevent the warning message from appearing, install the built-in viewer on a PC that does not have such anti-virus software installed.

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.

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.

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.

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.

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.
