Installation
Hardware Installation
Please verify that your product package contains all the accessories listed in the foregoing Package Contents. Depending on the user’s application, an Ethernet cable may be needed. The Ethernet cable should meet the specs of UTP Category 5 and not exceed 100 meters in length.
Connect the power adapter jack to the Network
Camera before plugging in to the power socket. This will reduce the risk of accidental electric shock.
Upon powering up, the device runs through a self-test procedure and the front LEDs will blink between green and red a few times. If self-test passes, the LEDs will shut off and the Network Camera will be on stand-by and ready for software installation. If self-test fails the red LED will blink several times. Refer to Appendix A for troubleshooting.
The 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 device and the state of voltage can be monitored from the initial state 'LOW'. The relay switches Pin 3 and Pin 4 can be used to turn on or off an external device.
Consult with the dealer of the peripherals for correct installation.
1 DI+ INPUT (Max. 50mA, 12VDC) 2 DI- INPUT (Initial state of DI is Low) 3 SW_COMMON OUTPUT (open from SW_OPEN at initial state) 4 SW_NOPEN OUTPUT (Max. 1A, 24V DC or 0.5A, 125VAC)

Software Installation
In this manual, "User" refers to whoever has access to the Network Camera, and "Administrator" refers to the person who can configure the Network Camera and grant user access to the camera.
At the end of the hardware installation, the Administrator must place the product software CD into the CD-ROM drive of the PC running in MS Windows. An auto-run program will pop up (If the program is not on auto-run, go to the root directory of the software CD and click on “autorun.exe”).
Click on “Software Utility” item, after the window contains changed, click on “Installation Wizard” to run Vivotek’s installation program.

www.vivotek.com
Upon Installation Wizard’s start up, a searching box will pop up. This program searches for Vivotek’s product on the same LAN:
After searching, Vivotek Video Servers or Network Cameras will be located by the Installation Wizard. There may be several entries shown in the window. The Administrator may differentiate the Network Cameras with the serial number.
- 9 -
www.vivotek.com
For the series number in the “Serial Number” field, please check the label on the bottom of the camera.
The IP addresses shown in the "Current IP Address" field re flect those on the local network. They may be from the DHCP server. If there is no DHCP server, the camera will try to find a free IP address (this takes from 15 second to 3 minutes, depending on the LAN status). The method of finding IP address is seeking from
192.168.0.99, to 192.168.0.254. If any of the address inside this range is free, the Network Camera will be assigned to this IP address, and its subnet mask would be
255.255.255.0. If none of the addresse s is free, the Network Camera will try the range from 192.168.0.2 to 192.168.0.98. After a n IP address is assigned to the camera, the “Activity” status LED blinks.
The Vivotek’s new UPnP function will always assign an IP address for the Network Camera. The Administrator can click on button “Link to selected device” to connect the I.E. to the camera. If the camera is not on the IP installer list, click on the “Search” button to search for the camera on the LAN.

Initial Access to the Network Camera
Check Network Settings
The Network Camera can be connected either before or immediately after software installation onto the Local Area Network. The Administrator should complete the network settings on the configuration page, including the correct subnet mask and IP address of gateway and DNS. Ask your network administrator or Internet service provider for the detail information. By default the Network Camera requires the Administrator to run installation every time it reboots. If the network settings are to remain unchanged, disable the Install option. Refer to “Netw ork settings” on the System Configuration page for details. If any setting is entered incorrectly and cannot proceed to setting up the Network Camera, restore the factory settings following the steps in the “T roubleshooting” chapter of the Appendix.
Add Password to prevent Unauthorized Access
The default Administrator’s password is blank and the Network Camera initially will not ask for any password. The Administrator should immediately implement a new password as a matter of prudent security practice. Once the Administrator’s password is saved, the Network Camera will ask for the user’s name and password before each access. The Administrator can set up a maximum of twenty (20) user accounts. Each user can access the Network Camera except to perform system configuration. Some critical functions are exclusive for the Administrator, such as system configuration, user administration, and software upgrades. The user name for the Administrator is permanently assigned as “root”. Once the password is changed, the browser will display an authentication window to ask for the new password. Once set, there is no provision to recover the Administrator’s
password. The only option is to restore to the original factory default
settings.

How to Use
Authentication
After opening the Web browser and typing in the URL of the Network Camera, a dialogue window pops up to request a username and password. Upon successful authentication, the following figure is displayed.
The foreground is the login window and the background shows the message if authentication fails. The user may check the option box to save the password for future convenience. This option is not available to the Administrator for obvious reason.

Permission request depends on the Internet security settings of the user’s PC or notebook. If the highest security level is set, the computer may prohibit any installation and execution attempt. This plug-in has been registered for certificate
and is used to display the video in the browser . Users may click on
to proceed.
If the web browser does not allow the user to continue to install, check the Internet security option and lower the security levels or contact your IT or networking supervisor for help.

Client Settings
At the initial access to the “Connection type” page in Windows, the web browser will
ask for a new plug-in installation, the plug-in being the Network Camera. This plug-in
has been registered for certification and can be used to change the parameters at the
client’s site. The user may click on
to install the plug-in. If the web browser
does not allow the user to complete the installation, check the Internet security to
lower the security level or contact your IT or networking supervisor.
There are two settings for the Client site. One is “Media Option” for the User to
determine if audio should be muted. The other is “Protocol Option” which allows
choices on connection protocol between client and server. There are three protocol
choices to optimize your usage - UDP, TCP and HTTP.
The UDP protocol allows for more real-time audio and video streams. However,
some packets may be lost due to network burst traffic and images may be obscured.
- 18 -
www.vivotek.com
The TCP protocol allows for less packet loss and produce a more accurate video
display . The downside with this protocol is that the real-time effect is worse than that
with the UDP protocol.
The HTTP protocol must be selected if the network is protected by a firewall and it
only allows HTTP Port (80) to be opened. In this mode, audio will not be sent and only
video is operational. If no special need is required, UDP protocol is recommended.
Generally speaking, the client’s choice will be in the order of UDP → TCP → HTTP.
After the Network Camera is connected successfully, “Protocol Option” will indicate
the selected protocol. The selected protocol will be recorded in the user's PC and will
be used for the next connection. If the network environment is changed, or the user
wants to let the web browser to detect again, manually select the UDP protocol, save,
and return HOME to re-connect.

Administrator’s Capabilities
Fine-tuning for Best Performance
There are a few choices the Administrator is allowed to maximize the capabilities of
the Network Camera. Best performance generally equates to the fastest image
refresh rate with the best video quality, and at the lowest network bandwidth as
possible. The three factors, “Maximum frame rate” , “Fix bit rate” , and “Fix quality” on
the Video Configuration page, are correlative to allow for achieving the best
performance possible.
For Best Real-time Video Images
To achieve good real-time visual effect, the network bandwidth should be large
enough to allow a transmission rate of greater than 20 image frames per second. If
the broadband network is over 1 Mbps, set the “Fix bit rate” to 1000Kbps or
1200Kbps, or set “Fix quality” at the highest quality . The maximum frame rate is 25
fps in a 50Hz system and 30 fps in a 60Hz system. If your network bandwidth is more
