Before You Use
Surveillance devices may be prohibited by law in your country. Though Network Camera is not only a high performance web equipped camera but also a flexible surveillance system, ensure that the operation of such devices are legal before installing this unit for surveillance.
It is important to carefully check the contents with the "Package Contents" chapter after opening the package. Fully read and follow the “Installation” chapter to prevent damage caused by abnormal usage and reduce most problems during usage.
Basically Network Camera is a network device and should be easy to use for those who already have basic network knowledge. If there is a system error and it does not recover easily due to erroneous configuration, refer to the appendix "Troubleshooting” for appropriate operation.
Network Camera has been designed to build various applications for video sharing, general security or demonstration purposes. Understanding the meaning of each parameter in “How to Use” chapter can best utilize Network Camera and ensure correct operations. To those creati ve and professional developers, chapter of "URL Commands of Network Camera" will be a very helpful reference to customiz e existing homepages or integrating with current web server.
Those paragr ap hs p r eced ed by should be fully understood and cautioned. Ignoring the warnings may result in serious hazards.

Installation
Hardware installation
All necessary accessories can be found in the product package except for the Ethernet cable that depends on the user’s environment. The Ethernet cab le should meet UTP category 5 that cannot exceed 100 meters.
Connect the jack of the power adapter to Network Camera prior to plugging the utility end into the utility power socket. It will reduce accidental electric surge shock.
As soon as the power adapter is plugged into the utility socket, the front LED will switch between green and red for several times. After passing the self -test, the LED will shut off and Network Camera will standby for software installation. Otherwise refer to Appendix A for troubleshooting.
Network Camera provides a general I/O terminal block with one digital input and one relay switch for device control. Pin 1 and pin 2 can be connected to an external sensor an d the state of voltage will be monitored from the initial state 'LOW'. The relay switch of pin 3 and pin 4 can be used to turn on or off the external device.
Consult with the dealer of the peripherals for correct installation.1

Software installation
In the following content, "user" refers to those who can access Network Camera and "administrator" refers to the supervisor who can configure Network Camera and grant users access.
When completing the hardware installation, administrators needs to put the product software CD into the CDROM drive of a PC running with MS Windows. An auto-run program will popup (If the program is not auto-run, please cli ck on the autorun.exe at the root directory of the software CD to in voke the program).
Click on the IP installer to invoke Vivotek’s installation program.
www.vivotek.com T: 886-2-22404099 F: 886-2-22404097
When the IP installer starts up, a searching box will popup, that is the program is searching Vivotek’s product on the same LAN:
After searching the LAN, the main window of IP installer will pop up.
The IP address shown in "Current IP Address" field depends on the local network. It may get from the DHCP server. If there is no DHCP server, the camera will try to find a free IP address for itself (this would take longer time, from 15 second to 3 minute, depends on your LAN status). After the IP address is assigned to the camera, The “Activity” status LED will blink.
www.vivotek.com T: 886-2-22404099 F: 886-2-22404097
Vivotek’s new uPnP function of the camera will always assign an IP address for the itself. Therefore, the administrator can click the “Link to selected device” to invoke I.E. to connect the camera. If the camera is not in the list of IP installer, click “Search” button to search camera on the LAN.
For the series number field, please check the label attached on the bottom of the camera.

First access to Network Camera
Check network settings even if connected already
Although Network Camera already can be connected after software installation from Local Area Network, administrators should complete the network settings in the configuration page including the correct subnet mask and IP address of gateway and DNS. Ask for the network administrator or Internet service provid er for the detail information. By default Network Camera will need administrator's installation every time it reboots. If the network settings are sure to work all the time, disable the install option. Refer to “Network settings” in sy stem configur ation page for details. Once any setting is entered incorrectly and thus hangs Network Camera, restore the factory settings according to the steps in troubleshooting.
Add password to protect from offense from strangers
Since the administrator’ s password is blank by default, Network Camera will not ask for any password. However the administrator should change the password as soon as possible to protect from network intruders. Once the administr ator’s password is saved, Network Camera always needs user name and password before access. The administrator can setup at most twenty user accounts. Each user is able to access Network Camera except for system configur ation. Some critical functions are limited only for administrators such as system configur ation, user administration and software upgrade. The user name of the administrator is assigned to “root” permanently. Once the password is changed, the browser will display an authentication window to ask for the new password. There is no way to discover administrator’s password . If the password is forgotten, only restoring factory defaults can help.

How to Use
Authentication
After opening the Web browser and typing in the URL of Network Camera, a dial og ue window may pop up to request a username and password except that the administrator does not save any password. Upon successful authentication, the main page will display like the figure below.
In the figure, the foreground is the login window and the background shows the message when authentication fails. The user may check the option to save the password for future convenience.

Installing plug-in
If it is initial access to Network Camera in Windows, the web browser may prompt for permission to install a new plug-in that is provided by Network Camera. Prompt or not and the prompt message depend on the Internet security settings of user’s PC or notebook. The highest security level may prohibit any installation and execution attempt even the plug-in is safe. This plug-in has been registered for certificate and is
used to display the motioned pictures in the browser. Users may click on
to
proceed. If the web browser does not allow the user to install, check the Internet security option to lower security levels or contact network supervisors.

“Digital Output” Click on the “On” or “Off” button can turn the Digital output to on or off status. “Client Settings” Click on the button would link to client setting pages, please check the following session for more details. “Configuration” Only administrator can access camera configurations. Direction buttons The buttons contain: Left, Right, Up, Down and Home function. The home button would command camera to the center of the camera. “Go to” Once the administrator set the preset posi tions, users can move the camera to the positions through this control.
“Pan speed” This button can set the moving range of “Left” and “Right” commands. “Tilt speed” This button can set the moving range of “Up” and “Down” commands. “Auto Pan” This button would command the camer a to pan from the current position
to the most left or most right, than to the opposite position. After reaching both vertical end position, the camera would stop at the same position as the one before pan.
“Stop” The button stops the “Auto Pan” command or “Auto Patrol” command. “Auto Patrol” This button would command the camera to patrol between the preset
positions in the patrol list that can be set on the “Camera control page”. After one patrol cycle, the camera woul d stop at the sam e position as the o ne before the patrol .

Client Settings
If it is the first access to “Connecti on type” page in Windows, the web browser will ask to install a new plug-in that is provided by Network Camera. This plug-in has been registered for certificate and is used to change the parameters at the cli ent side. Users
may click on
to install the plug-in. If the web browser does not allow the user
to install, check the Internet security to lower the security level or contact network supervisors.
There are two settings for the client side. One is “Media Option” for users to determine if the audio should be muted. The other is “Protocol Option” to choose the connection protocol between client and server. There are three protocols to op timize your usage - UDP, TCP and HTTP. With UDP protocol, audio and video streams can be
www.vivotek.com T: 886-2-22404099 F: 886-2-22404097
- 15 -
more real-time. But some packets may be lost due to network burst traffic and images will be obscure. If TCP protocol is selected, packet loss would not occur and video display will more accurate. But the real-time effect is worse than UDP protocol. If the network is protected by a firewall and it opens HTTP p ort (80) only , HTTP protocol must be selected. In this mode, audio will not be sent and you can see the vi deo only. If you have no special needs and no idea to choose one among them, simp ly choose UDP. Generally the client will automatically try these protocols by the following order, UDP → TCP → HTTP. After the client connects to the Network Camera successfully, “Protocol Option” will show the working protocol. The chosen protocol will be recorded in the user's PC and used for next connection. If the network environment is changed or users want to let web browser detect again, select UDP manually to save and then return HOME to connect again.

Administrator’s capability
Tune the best performance
The best performance means the image refresh rate shoul d be the fastest as possibl e and the video quality should be the best as possible at the lowest network bandwidth as possible. Three factors, “Maximum frame rate”, “Fix bit rate”, and “Fix quality” in the Video configuration page, are correlative to the performance.
My priority is real-time motioned images
To achieve the real-time visual effect, the network bandwidth should be large enough to transmit 20 image frames or more. If you are in the broadband network over 1 Mbps, you can fix the bit rate to 1000Kbps or 1200Kbps, or fix the quality to achieve the maximum frames. The maximum frame rate is 25 in 50Hz system and 30 in 60Hz system. If your network bandwidth is more than 384Kbps, you can fix the bit rate according to your bandwidth and set the maximum frame rate to 25 or 30. If the images vary dramatically in your environment, you may slow down the maximum
www.vivotek.com T: 886-2-22404099 F: 886-2-22404097
- 18 -
frame rate to 20 to decrease the transmitted data for better video quality since human could not easily tell the difference between 20 and 25 or 30 frames per second. If y our network bandwidth is below 384 Kbps, you should fix the bit rate according to your bandwidth and try out the best performance by tuning the maximum frame rate. The larger frame rate in slow network will blur the images. You may also try to choose “Half” in size option for better images or “Halfx2” for larger image size. Note that even you have well tuned the parameters, the performance may still vary from person to person when multiple users view at the same ti me. Because the network has burst constraint and everyone’ s en vironment is not the same, an y poor connecti on will drop the normal performance.
My priority is clear identification for each image
To have the best video quality, you should fix the quality to detailed or excellent and tune the maximum frame rate to suit for your network bandwidth. If you get some broken pictures in slow network, you can choose T CP protocol i n “Connection type” for more accurate transmission but the recei ved images may have certain time delay . Note that any slow connection in multiple users will drop the proper performance.
I want to compromise between real-time and clear images
If you have a broadband network, choose fix quality to normal or better r ather than fix bandwidth. Otherwise fix the bandwidth according to your actual network speed and set the frame rate to 30. If the images look bad, sel ect the lower frame rate abov e 15. If the images are not improved, select the lower bandwidth.
