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.
