Physical Description Rear Panel Ethernet 10/100 socket Connect to Ethernet network with a UTP category 5 cable that cannot exceed 100 meters. Once the Ethernet cable is connected without error, Network Camera will utilize Ethernet interface regardless of modem connection. COM port This RS232 serial port can connect with a modem or included null modem cable to utilize dial-up network when Ethernet is not available.
General I/O terminal block 1 Å DI+ INPUT 2 Å DI- INPUT 3 Å SW_COMMON OUTPUT (short with NC at initial state) 4 Å SW_NOPEN (Max. 1A, 24VDC or 0.5A, 125VAC) 5 Å RS485 B (inverting) 6 Å RS485 A (non-inverting) (Max. 50mA, 12VDC) OUTPUT Network Camera provides a very flexible general I/O interface to combine with the user’s security devices such as sensors, alarms, lighting or door locks. The general I/O terminal block has six pins for device control.
Status LEDs Each time Network Camera starts, it will perform a Power-On Self Test, abbreviated as POST hereafter, to examine every hardware module. As soon as the administrator plugs in the power adapter, both LEDs under the network LED will flash one by one until the POST is done. If any module fails, both LEDs will indicate to the users the error according to the pattern listed in Appendix A. If the result is good, both LEDs will turn off for a while and then follows the pattern below.
Restore button There is a button hidden in the box for restoring the system factory default settings. When the system fails to install or operates abnormally, use the included assistant stick in the package and follow the following procedures to reset the system back to its original status. Poke the assistant stick into the hole to press down on the restore button. Restart the system by unplugging and re-plugging the power jack.
How to Install To easily fit into various environments, Network Camera automatically detects the attached interfaces and configures itself to the best condition. Therefore users need not care how to select the network between Ethernet and modem, and whether the Ethernet speed is 10Mbps or 100 Mbps. The high performance built-in CCD and lens always give users delicate image quality. Network Camera supports Ethernet and modem interfaces according to the user's existing network.
Ethernet Environment Hardware installation Before installing multiple Network Cameras at the well-chosen locations, the administrator should memorize the serial numbers on the packages respectively for future use. Cable connection Shut down all the peripheral devices prior to connection. Connect the supplied cables from Network Camera to related devices according to the following steps. Note that the power adaptor must be kept unplugged until other cables are firmly connected. 13 www.vivotek.
Power on Make sure all cables are correctly and firmly connected before turning on Network Camera. Turn on cameras, sensors, alarm devices, and then attach the power adaptor of Network Camera to the electric power socket*. After the POST (power-on self test) is complete and the result is successful, Network Camera is ready for software configuration as described in this manual. At this stage, network speed and video modulation type are automatically detected.
Software configuration Easy way with installer program In order to configure Network Cameras remotely, administrators should keep the serial numbers of the new Network Cameras for identification and initial passwords. After successfully mounting Network Cameras in the proper position, run the Installer program on the appropriate PC to locate the newly installed Network Cameras. Network Cameras also support manual setup procedures to non-Windows based environments. The manual procedure is described next.
The IP address shown in "Current IP Address" field is for the administrator's reference. If the administrator wants to use another IP address, modify the IP text field below the list window. If the administrator wants to fix the IP address of the unit, check the option "Use this IP whenever system boots" to skip future installation procedures. Otherwise the unit will need installation whenever it is restarted. When IP and options are O.K., click on .
IP address is valid. If the IP is not taken by another network device in the network, the Installer program will continue with the setup. Otherwise another message window will warn that the assigned IP conflicts. In this case, administrators should ask the network supervisor for a vacant IP address. 17 www.vivotek.
After successful notification, administrators may keep the address information for user’s request. After clicking on on , the "Assigned" field will be labeled "Yes". Administrators may click directly to access the newly installed server in the default browser. While checking “Use this IP whenever system boots”, a dialog window may pop out to ask for “Server 18 www.vivotek.
FTP Port” and “Root Password” because they are already changed to other than default settings. If the settings are lost, restore default settings and use installer to install again. Once installation is complete, administrators should follow the actions in the "First access to VisualServer" section for necessary checks and configurations. Experienced administrators may use the customized config.ini script file to perform a quick setup via FTP.
Manual way with existing programs For those environments such as MAC, Linux, Unix or other operating systems, whose installer is not yet available, some common network tools including ARP and PING can be used to install Network Camera. Make sure ARP and PING programs exist in your operating system. First, type arp –s “assigned IP address” “Ethernet address” to add an entity in the system’s name table.
First access to Network Camera When connecting to Network Camera for the first time, administrators should check security and network settings on the configuration page. For complete protection from illegal usage, Network Camera provides two privileges and always needs user name and password before access. The standard level is the USER mode that consists of twenty user profiles. Each user is able to access Network Camera except for system configuration.
installation procedure every time the system boots up. Details about configurations are described in the "How to Use" section. Related figures are attached for easy reference. 22 www.vivotek.
Modem Environment Hardware installation Before installing Network Camera, the administrator should memorize the serial numbers on the packages respectively for the initial passwords. To use a dial-up network, the Ethernet socket should be left disconnected since Ethernet is the first priority among available interfaces. After powering up, Network Camera will detect if any external modem is connected to the modem port. Once a modem is detected, the heartbeat LED will flash periodically.
Cable connection Shut down the peripheral devices prior to connection. Connect the supplied cables from Network Camera to the related devices according to following steps. Note that power adaptor must be kept unplugged until other cables are firmly connected. For the first access to Network Camera without Ethernet, administrators may use the included null modem cable to connect to COM for direct connection.
Software configuration For the first time, users should connect the included null modem cable between the COM port of Network Camera and any COM port of the PC for initial setup. Install a new modem Open the control panel and double click the modems icon. Check "Don't detect my modem......" item and click on to install a new modem. 25 www.vivotek.

Double click the newly setup connection. A dialing information window will pop up. Enter “root” as user name and the serial number labeled on the bottom side of the box as the password and click on . The user name and password are identical to what is used in web access and may be changed by administrators after successful installation. Notice that the letters in the serial number should be capital form. For example, type 'A' instead of 'a'.
First access to Network Camera Through direct connection by null modem cable administrators can open the default web browser and type in 200.1.1.1 as the address and press enter. Note that 200.1.1.1 will be the default IP address in a dial-in connection and 200.1.1.100 will be the given IP address for the user's PC by Network Camera. The user name and password are the same as what was entered during installation.
the administrator should add these user profiles in the Security option. When Network Camera accepts dial-in connection and acts as a server, the user name and password used in dialing are the same as what was stored in the user database managed for web access. Any managed user can be authorized during PPP negotiation and access web pages. However only administrators can access the configuration page. There is more information needed for correct modem operation.
How to Use Network Camera is a well-designed stand-alone network camera. With the built-in web server, authorized users may use web browser Internet Explorer to watch the video and hear the audio captured by Network Camera. The powerful video compression processes up to 30 frames per second and makes the scene in your browser as real-time display. The powerful audio compression processes the real-time audio and makes the synchronization of video and audio correctly.
Authentication After opening the Web browser and typing in the URL of Network Camera, a dialogue window will pop up to request a username and password. For administrator’s initial usage of Network Camera, enter the username as “root” and the password as the serial number in capital letters.

If the network performance is worst, please select the ”UDP protocol“ as the communication protocol in “client setting” After everything is set, click on . A warning message will pop up. Click on to confirm. Network Camera will automatically restart. If "Reset network at next boot" is kept checked, run the installer procedure again. Otherwise Network Camera will restart automatically.
Video codec parameters Options on this page will affect the image on the main page seen by users. "Text on Video" will be displayed above the video window with a timestamp. The timestamp is captured from date and time of Network Camera that is maintained by a built-in real-time clock. "Size" option allows users to adjust the image size taking into consideration bandwidth and visual effect. Three options are available including half, half×2 and normal.
is far less than JPEG in normal cases but it still depends on the level of difference between every two sequential images. There are three dependent parameters provided for adjustment. "Maximum Frame Rate" limits the maximal refresh frame rate that can be combined with the "Video Quality Control" to optimize the bandwidth utilization and video quality. If users want to fix the bandwidth utilization regardless of the video quality, choose "Fix Bit Rate" and select the desired bandwidth.
To adjust image settings for best visual quality, press and a motion picture window will pop up for your reference. There are four fields including "Brightness", "Contrast", "Hue" and "Saturation" for video compensation. . Each field has eleven levels ranged from -5 to +5. The user may press settings or to fine-tune the image. When the image is O.K., press to memorize the image to recall the original settings. If parameters are changed without saving, they will be used until the next system startup.
Motion detection Please note that the option "Enable Motion Detection" on the video page must be enabled to make detection effective. Network Camera allows administrators to define at most three detection windows to cover different areas. To monitor a specific area, click to add a new window. The typed text in "Window Name" will show at the top of the window. Use the mouse to drag the border to the desired size or title bar for location.
The following figure shows the screen when is clicked. The monitoring windows will be marked by red squares. 52 www.vivotek.
Camera positioning device configuration Since Network Camera can be used in either PPP network or Ethernet network, the single serial port can control either external serial port devices like camera positioning devices or a data modem. While in PPP interface, go to Modem page for modem configuration. Options on this page will be ignored. To control the external PT positioning device, “Enable camera control” must be checked and the control panel or buttons will thus display on the main page.
more commands, a comma ‘,’ should be inserted to separate each command. Each comma represents 200 milliseconds. For instance, a command to pan left may be “01000305” and a command to stop panning may be “01000300”. The user may edit the applicable command as “01000305,01000300” in the “Move Left” field. This means the camera will pan left for 200 milliseconds. The maximal length of a command string is 60 which is equivalent to 30 hexadecimal bytes.
Modem and dialup settings In PPP interface, a modem option will work instead of camera control. Configurations include modem initialization and outside dial-up server. If the users will setup with external sensors and alarms for property security, dial-out is needed to send some snapshot-attached e-mails when the preset conditions are triggered. In such applications, also remember to choose Network option to enter mail server address and recipient's e-mail address.
on the connection for the specific period. The range of this period is from 1 to 240 minutes, with 0 indicating a continuous connection. Administrators may let Network Camera keep the connection for a while to allow connections from outside. The IP address given by the ISP can be taken from the connection log that is mailed or uploaded when dial-up connection is successful. Setting the value to zero will make Network Camera always keep the connection.
Application Administrators can use combinations of options on the application page to perform many useful security applications. The sending method is selected at the bottom of the page. Both e-mail and FTP use the network settings on the network page. To use FTP to upload snapshots, a timestamp file name can help administrators identify the event. If "FTP put snapshot with date and time suffix" is disabled, the up-to-date snapshot will overwrite the file.
The other "Event operation" can be used to combine motion detection with devices attached to digital input, to drive devices attached to digital output, or send out snapshots for evidence. It helps users establish an easy security system. Administrators may choose any combination of conditions to form special applications according to their personal needs. Network Camera will continuously monitor the channel and digital input every half second.
Homepage layout settings Administrators may give Network Camera a different presence of homepage. The "logo graph" for the system logo in the upper-left corner can be hidden; or the default image from the system memory can be used; or an external resource can be used by assigning a URL. "background graph" is similar. Default images from system memory are quick to get but limited by memory size. Images from external resources can be larger and more beautiful but will need more time to load.
One-shot fast configuration via FTP For quick setup of Network Camera, the administrator can utilize the default CONFIG.INI that may be downloaded from the FTP daemon of Network Camera. To log into the FTP daemon, enter “root” as the user name and the same password used when connecting to the Web server. The serial number of Network Camera is the password for the initial access. Then administrators only need to modify necessary fields and then upload the file to Network Camera with the file name “CONFIG.

Appendix A. POST procedure After the power has been turned on, Network Camera will perform a self-diagnostic to locate any possible hardware defects. If the power indicator is dim at the beginning, the power fails to proceed further. While the POST is proceeding, the status LED indicators will keep blinking interchanged until finished or any fatal error happens. If either status LED indicator is dim at the beginning, the LED may be broken.
B. Frequently asked questions Q. What if I forget my password? A. Every access to Network Camera needs authentication. If you are one of the managed users, you have to ask the administrators for the password. If you are the administrators, there is no way to recover the root password. The only way to regain access to Network Camera is to utilize the default setting button on the rear panel to restore the factory settings and reinstall it. Q.
snapshots into memory upon events occurring. Q. How does Network Camera detect the supported PTZ cameras automatically? A. If there is no camera detected, Network Camera will monitor the CTS of the camera control cable continuously. As long as the CTS is detected, Network Camera will try to handshake with supported cameras until a supported camera is found. There is no more camera detection once a PTZ camera is recognized. Q. How many users are allowed to watch Network Camera at the same time? A.
A. Network Camera provides a custom camera command interface to control the cameras that are not supported. The details are described in the manual. Be sure the COM port settings are applied to the camera specification. The camera control cable included is shown in the package content. Prepare your own cable if necessary. The general PTZ command is composed of one start command and one stop command. When editing both commands in the edit box of the configuration page, use comma(s) to separate commands.
