The use of surveillance devices may be prohibited in your country by law. The
Network Camera is not only a high-performance web-ready camera but also can be
part of a flexible surveillance system. It is the user’s responsibility to ensure that the
operation of such devices is legal before installing this unit for its intended use.
It is important to first verify that all contents received are complete according to the
list in the "Package Contents" chapter. Take notice of the warnings in “Quick
Installation Guide” before the Network Camera is installed, then ca refully read and
follow the instructions in the “Install ation” chapter to avoid damages due to faulty
assembly and installation. This also ensures the product is used properly as intended.
The Network Camera is a network device and its use should be straightforward for
those who have basic network knowledge. The “Troubleshooting” chapter in the
Appendix provides remedies to the most common errors in set up and configuration.
You should consult this chapter first if you run into a system error.
The Network Camera is designed for various applications including video sharing,
general security/surveillance, etc. The “How to Use” chapter suggests ways to best
utilize the Network Camera and ensure proper operations. For the creative and
professional develope rs, the "URL Commands of the Network Camer a" chapter serves
to be a helpful reference to customize existing homepages or integrating with the
current web server.
For paragraphs preceded by the reader should use caution to understand
completely the warnings. Ignoring the warnings may result in serious hazards or
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 for 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 will first detect Ethernet. If it does not connect to Ethernet, the
Network Camera will try WLAN. During the searching and connecting process to the
wireless access point or station, the LED of the Network Camera will keep red. Until
the Network Camera is connected to the other wireless device, the LED will become
green and flash. Operating in either network mode, the green L ED will flash every
second as heartbeat to indicate alive.
Make sure the Ethernet is firmly connected to a switch hub. After attaching the
Ethernet cable plug in the power adapter . If the LED turns out to be steady green after
self-test, go to next paragraph “Software Installation” . If the Ethernet is not available,
the Network Camera will switch to wireless LAN mode.
The Network Camera provides a general I/O terminal block with one digital input and
one relay switch for device control. Pin 3 and Pin 4 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 1 and Pin 2 can be used to turn on or off an external device.
Consult with the dealer of the peripherals for correct installation.
1 SW_COMMON OUTPUT (open from SW_OPEN at initial state)
(close with SW_OPEN when set DO to ON)
2 SW_NOPEN OUTPUT (Max. 1A, 24VDC or 0.5A, 125VAC)
3 DI+ INPUT (Max. 50mA, 12VDC)
4 DI- INPUT (Initial state of DI is low)
The Network Camera also provides the auto iris lens connector . If the auto iris lens is
used, AES option in CCD settings must be turned OFF. And you also have to select
VIDEO drive or DC drive lens by select correct iris mode in CCD settings. The pin
assignment of the auto iris lens connector is as follows.
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 Wi ndows. 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.
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.
For the series number in the “Serial Number” field, please check the label on th e
bottom of the camera.
The IP addresses shown in the "Current IP Address" field reflect 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 o f the address in side thi s 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 addresses is free, the Network Camera will try the
range from 192.168.0.2 to 192.168.0.98. After an 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.
For the initial access to the Network Camera in Windows, the web browser may
prompt for permission to install a new plug-in for the Network Camera after a period
of time of downloading. 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 displ ay the video in the brows er. 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.
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 “Network 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 “Troubleshooting” 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
the password is set, there is no provision to recover the Administrator’s
password. The only option is to restore to the original factory default
settings.
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.
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.
The main page layout has two parts:
Configuration functions: The camera can be configured using these user
interfaces.
Camera View: What the camera sees.
“Digital Output”
Clicking on the “On” or “Off” b utton turns the digital output to either on or off
status.
“Snapshot”
Clicking on the “Snapshot” can get a JPEG format image of the current camera view
in another window.
“Client Settings”
Clicking on this button links you to the client setting page, please check the
following session for more details.
“Configuration” Only the Administrator can access camera configurations.
The camera view
The information bar at the top of the camera view shows the assigned caption and
the current date/time. The information bar at the bottom of the camera view shows
the current streaming mode and audio transmission mode. You can push/toggle
the talk button to talk to the remote server . The volume of speaker and microphone
can also be adjusted.
Media Options - For the User to determine whether to receive video, audio or
both.
Protocol Options – Which allows choosing on connection protocol between client
and server. There are two protocol choices to optimize your usage – UDP and HTTP.
The UDP protocol allows for more real-time au dio and video streams. However , some
packets may be lost due to network burst traffic and images may be obscured.
The HTTP protocol must be selected if the network is protected by a firewall which
allows only HTTP Port (80) to be opened. If there is no restriction, UDP protocol is
recommended. Generally speaking, the client’s choice will be in the order of UDP →
HTTP. After the Network Camera is connected successfully, “Protocol Options” 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 and save, then return to HOME to connect to the Network Camera.
Streaming Options – For users to select the video streaming types. Select
“Streaming Video” options, the video connection will keep alive to enable you to see
smooth video, while “Single JPEG” options will let you see the video in JPEG format
by client periodic updat e the JPEG image from serv er according to the “Frame rate”
settings.
Talk Button Control Style – For the User to determine whether to “click once and
talk” or “push to talk”.
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 six factors, “Size”, “Maximum frame rate”, “ Video codec type”, “Key
frame interval”, “Fix bit rate” , and “Fix quality” on the Video Configuration page, are
correlative to allow for achieving the best performance possible.
To achieve good real-time visual effect, the network bandwidth should be large
enough to allow a transmission rate of greater than 20 image fr ames 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 r ate is 25
fps in a 50Hz system and 30 fps in a 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 fps or 30 fps. If you are shooting fast-moving images, you
may want to slow the maximum frame rate down to 20 fps in order to lower the rate
of data transmission. This allows for better video quality and the human eyes cannot
readily detect the differences between those of 20, 25, or 30 frames per second. If
your network bandwidth is below 384 Kbps, set the “Fix bit rate” according to your
bandwidth and try to get the best performance by fine-tuning with the “ Maximum
frame rate”. In a slo w network, greater frame rate results in blur images. Another
work-around is to choose “Half” in the “Size” option for better images, or “Halfx2” for
a larger image view. Video quality performance will vary somewhat due to the
number of users viewing on the network; even when the parameters have initially
been finely tuned. Performance will also suffer due to poor connectivity because of
the network’s burst constraint.
In multi-user environment, the user who has poor network performance will receive
only the key frame in MPEG4 format. T ry to reduce the key frame interval can improve
the frame rate for poor network performance, but the penalty is the increasing of
network traffic. If the server is running on the Internet, select the “improve efficiency
in the multi-user environment” will improve the efficiency in the multi-user
environment.
Only Quality Images Will Do
T o have the best video quality , you should set “Fix quality” at “Detailed” or “Excellent”
and adjust the “Maximum frame rate” to match your network’s bandwidth. If your
network is slow and you receive “broken” pictures, go to the HTTP protocol in
“Connection type” and choose a more appropriate mode of transmission. The images
may suffer a time delay due to a slower connection.
If you have a broadband network, set “Fix quality” at ”Normal” or better, rather than
setting “Fix bit rate” . Y ou can also fix the bandwidth according to your actual network
speed and adjust the frame rate. Start from 30 fps down for best results but not
below 15 fps. If the image qualities are not improved, select a lower bandwidth
setting.
Select for Motion JPEG
The Network Camera is a camera with dual video codec, they’re MPEG4 and MJ PEG.
If MJPEG is selected, the camera will transmit video data in JPEG format. Therefore,
it requires higher bandwidth to view smooth video. General speaking, each normal
sized JPEG image would be 3k~12k bytes, depending on the selected vid eo quality
and contents. Together with the frame rate selected, the administrator can control
the bandwidth of each connection.
The Network Camera is shipped without any password by default. That means
everyone can access the Network Camera including the configuration as long as the
IP address is known. It is necessary to assign a password if the Network Camera is
intended to be accessed by others. T ype a new word twice in the first field to enable
protection. This password is used to identify the administrator. Then add an account
with user name and password for your friends in the second field. The Network
Camera can provide twenty accounts for your valuable customers or friends. Each
account identifies the access right rather than the real visitor. That allows multiple
visitors share the same account of different level. Each accou nt has four kinds of
privileges, which can be set individually . The “I/O access” privilege permits t he user
to access DI/DO of the server. The “Talk” privilege permits the user to send speech
to the Network Camera. The “Listen” privilege permits the user to listen sounds from
the server. You may edit or delete some users from the third field.
More Flexible Options for Viewers
If you want to have a guest account for viewers only, you just need to add a user
without password and disable all the privileges. Share the account to your friends to
access your camera.
Build a Multimedia Web Attraction Site
Demo on Multiple Sites – Mid-scale Service
The Network Camera can allow ten visitors on-line simultaneously. After Installation,
focus the Network Camera on any object you wish to share, and tell the visitors to
type in the web browser address. Caution: You may want to maintain your visitor’s list
in the security configuration page to block out unexpected visitors.
Product Demo for E-business – Large-scale Service
If the number of visitors has exceeded the limit, the Network Camera can allow the
"overload" view ers to see the snapsh ots in JPEG mode, o n the homepage. Thes e are
still images and will be refreshed periodically and automatically.
1. Click on “Client Settings” on the homepage,
2. Select “Single JPEG” in “Streaming Options”,
3. Set the snapshot interval to refresh the still image automatically. The longer the
snapshot interval, the better the snapshot mode works for multiple viewers.
If you want to expand to allow in more viewers, the host server should be able to
handle large network traffic, which must handle the picture refreshing from the
Network Camera.
Set the Network Camera up as an FTP client to upload the pictures. The access to the
Network Camera will be independent of the number of viewers and the picture quality
will remain constant.
3. Fill in the FTP related settings including server, server port, user name and
password, as well as the upload path if it is specified by the web space,
4. Click on “Save”,
5. Click on “Application” in the left column,
6. Select the day or days of the week in “Weekly schedule” you want to upload the
pictures,
7. Select “Sequential operation” and set the interval,
8. Unselect “FTP put snapshots with date and time suffix” as the upload method and
click on “Save”,
9. The image file uploaded to the web space is named “video.jpg” . Check if the file is
successfully uploaded to the correct folder,
10. Prepare a homepage with the embedded image reference to the image file
uploaded via FTP in advance.
If the web space has no FTP service
An auto-refresh homepage can be used to periodically poll the newest image from the
Network Camera. It is most efficient if using a free web space provider as the FTP
service may be limiting.
1. Prepare an auto-refresh homepage as the following example. The URL of image is
http://“IP address of the Network Camera”/cgi-bin/video.jpg. Modify the IP address
according to your Network Camera. Define the refresh interval according to your
network bandwidth for best result. If the refresh rate is too fast and there is a large
number of visitors, this may overload the Network Camera and slows the response.

The Administrator can combine options
on the application page to perform many
useful security applications. There are
two trigger sources coming from
attached devices, such as for motion
detection. There are also two kinds of
actions responding to such events,
including uploading snapshots over the
Internet and driving other attached
devices. To upload the snapshots, the
User can choose either email or FTP according to user’s needs. Both e-mail and FTP
use the network settings on the Mail & FTP pag e. Refer to the definition section for
detail configuration.
1. Click on “Configuration” on the
homepage,
2. Click on “Application” in the left
column,
3. Check the weekdays as you need and

"Get IP address automatically" & “Use fixed IP address”
The default status is “Get IP address automatically” . This can be tedious having to
perform software installation whenever the Network Camera starts. Therefore, once
the network settings, especially the IP address, have been entered correctly, select
“Use fixed IP address” then the Network Camera will skip installation at the next
boot. The Network Camera can automatically restart and operate normally after a
power outage. Users can run IP installer to check the IP address assigned to the
Network Camera if the IP address is forgotten or using the UPnP function provided by
the Network Camera (MS Windows XP provides UPnP function at My Network Place).
As for how to get IP address automatically, please refer to the section of Software
Installation.
General
“IP address” This is necessary for network identification.
“Subnet mask” It is used to determine if the destination is in the same subnet. The
default value is “255.255.255.0”.
“Default router” This is the gateway used to forward frames to destinations in
different subnet. Invalid router setting will fail the transmission to destinations in
different subnet.
“Primary DNS” The primary domain name server that translates hostnames into IP
addresses.
“Secondary DNS” The secondary domain name server that backups the Primary
DNS.
“HTTP port” This can be other than the default Port 80. Once the port is changed,
the User must be notified the change for the connection to be successful. For instance,
when the Administrator changes the HTTP port of the Network Camera whose IP
address is 192.168.0.100 from 80 to 8080, the User must type in the web browser
“http://192.168.0.100:8080” instead of “http://192.168.0.100”.
Streaming
“UDP audio channel port” This can be something other than the default port 5002
in order to work with the port opened by the firewall.
“UDP video channel port” This can be something other than the default port 5003
in order to work with the port opened by the firewall.
“Enable DDNS” This option turns on the DDNS function.
“Provider” The provider list contains four hosts that provide DDNS services. Please
connect to the service provider’s website to make sure the service charges.
“Host Name” If the User wants to use DDNS service, this field must be filled. Please
input the hostname that is registered in the DDNS server.
“Username/E-mail” The Username or E-mail field is necessary for logging in the
DDNS server or notify the User of the new IP address. Note: when this field is input
as “Username” the following field must be input as “Password”.
“Password/Key” Please input the password or key to get the DDNS service.
“Enable UPnP” This turns on or off the UPnP function. When UPnP is turned off , the
camera cannot be found through network neighbors in MS Windows XP. If the UPnP
network component is installed in Windows XP , the hostname of the Network Camera
will be shown with bracketed IP address in the Network neighbors. Ex: Network
Camera with Pan/Tilt (xxx.xxx.xxx.96). That is: The hostname of the Network
Camera is “Network Camera with Pan/Tilt”, and the IP address of the Network
Camera is xxx.xxx.xxx.96, depends on the last value of the IP address assigned to
the Network Camera.
“Enable UPnP Port Forwarding” This turns on or off the UPnP port forwarding
function. If your camera is behind an NAT router and your router supports UPnP port
forwarding, turn on this option will help you to access your camera.
“Save” Click on this button to save current settings for the DDNS service and UPnP
function.

change this value from 1 to 65535. After the change, the external FTP client program
must change the server port of connection accordingly.
“1st FTP server” The domain name or IP address of the external FTP server. The
following user settings must be correctly configured for remote acce ss.
“1st FTP server port” The port to access the external FTP server.
“1st FTP user name” Granted user name on the external FTP server.
“1st FTP password” Granted password on t h e external FTP server.
“1st FTP remote folder” Granted folder on the external FTP server. This folder is for
system log information and for images captured due to sequential operation or digital
input events. The string must conform to that of the external FTP server. Some FTP
servers cannot accept preceding slash symbol before the path without virtual path
mapping. Refer to the instructions for the external FTP server for details. The folder
privilege must be open for upload.
“1st FTP remote folder for motion detection” Granted folder on the external
FTP server. This folder is for images captured due to motion detection events. The
string must conform to that of the external FTP server. Some FTP servers cannot
accept preceding slash symbol before the path without virtual path mapping. R efer
to the instructions for the external FTP server for details. The folder privilege must
be open for upload.
“1st FTP passive mode” The Network Camera is located inside the network
protected by a firewall, data connection for FTP may be prohibited. By selecting
passive mode, the FTP can bypass the rule and allow snapshot upload to proceed. If
the passive mode is selected, the Network Camera can automatically attempt for
active mode, if the external FTP server does not support passive mode.
“2nd FTP server” The domain name or IP address of the backup FTP server.
“2nd FTP server port” The port to access the backup FTP server.
“2nd FTP user name” Granted user name on the backup FTP server.
“2nd FTP password” Granted password on the b a ckup FTP server.
“2nd FTP remote folder” Granted folder on the backup FTP server . This folder is for
system log information and for images captured due to sequential operation or digital
input events.
“2nd FTP remote folder for motion detection” Granted folder on the external
FTP server. This folder is for images captured due to motion detection events.
“2nd FTP passive mode” Passive mode setting for the backup FTP server.
“Text on video” The text will be displayed in the black bar above the video window
with a timestamp. The timestamp is captured from date and time of th e Network
Camera that is maintained by a built-in real-time clock.
“Color” Select either for color or monochrome video display.
"Size" There are five options for three video sizes. “Half” is the quarter size of
“Normal” and “Normal” is the quarter size of “Double”. “Half x 2” has the same video
size as “Normal” but of a lesser quality, while consuming less network bandwidth.
“Normal x 2” has the same size as “Double” but of a lesser quality.
“Video codec type” It can be either MJPEG or MPEG4. In MJPEG mode, the video
frames are independent. In MPEG4 mode, there are I frames and P frames. T o decode
a P frame need the information of previous frame. MPEG4 consumes much less
network bandwidth than MJPEG.
There are five dependent parameters provided for video performance adjustment.
"Maximum frame rate" This limits the maximal refresh frame rate, which can be
combined with the "Video quality control" to optimize the bandwidth utilization
and video quality. If the User wants to fix the bandwidth utilization regardless of the
video quality, choose "Fix bit rate" and select the desired bandwidth. MPEG4 video
are composed by I frames and P frames as the following sequence.
IPPPPPIPPPPPIPPPP… “Key frame interval” determines how many repeated P
frames will appear after one I frame. Large “Key frame interval” can reduce the bit
rate, but cause image corrupt longer if there is packet loss while transmission. “Fix bit rate” option and “Key frame interval” option are only available in “MPEG4”
mode. The video quality may be poor due to the sending of maximal frame rate within
the limited bandwidth when images are moving rapidly. Consequently, to ensure
detailed video quality (quantization rate) regardless of the network, it will utilize
more bandwidth to send the maximal frames when images change drastically.
"Flip" Vertically rotate the video.
"Mirror" Horizontally rotate the video. Check options both if the Network Camera is
installed upside down.
“Improve efficiency in the multi-user environment” Check this option to
improve efficiency in the multi-user environment when running in the low bandwidth
environment. But it will cause each connection slow a few minutes when connection
established.
“Time stamp on video” When selected the time stamp format is:
a) “Size” becomes Normal or Double, “Text on video
b) “Size” becomes half, “hh:mm:ss yyyy/mm/dd”

“Transmission mode” There are five options to select. For all the modes, only one
client can talk to the server at the same time.
“Full-duplex (Talk and listen simultaneously)” In this mode, the User can talk
to the server while listening sound from the server simultaneously.
“Half-duplex (Talk or listen, not at the same time)” In this mode, the User can
talk to the server or listen from the server, but not at the same time.
“Simplex – Talk only” In this mode, the User can only talk to the server.
“Simplex – Listen only” In this mode, the User can only listen from the server.
“Disable” In this mode, the audio is disabled in both directions.
“Send audio from the active client to all the other clients” In half duplex
transmission mode, select the option to talk to the server and broadcast your voice to
all the other clients.
“Improve audio quality in low bandwidth environment” If the Network Camera
works in versatile or low network bandwidth environment, the User can check this
option to improving audio quality by sacrificing some real-time synchronization.
“Audio source” Select source from external or built-in microphone.
“Acoustic echo cancellation” In full-duplex mode, the server can play sound from
the client and receive sound from the environment and send to client. Since the
sound from the client is played by server, it will also be received by the server’s
microphone and send back to client. That is the client will hear its echo. Select this
option can prev ent echo by sacrificing the video frame rate.
“Bit rate” There are three kinds of bit-rate for audio. 32Kbps and 24Kbps are
suitable for both music and speech like audio while 8Kbps are suitable for only speech
like audio.
“Enable motion detection” Check this option to turn on motion detection.
Click on this button to add a new window. At most three windows can exist
simultaneously. Use the mouse to click, hold and drag the window frame to resize or

default setting of this option is checked.
“Snapshot file name prefix” Specify the prefix name for the snapshot file. Please
check naming rule of snapshot file for more detail.
Event Operation
“Delay second(s) before detecting next event” Set the time delay before
restarting to check on the triggering condition when the current condition is
triggered.
“Send pre-event image(s) when event occurs” Specify how many pre-event
snapshot will be sent if events happen.
“Trigger condition” There are four conditions relative to the digital input and three
windows for motion detection. More than one condition can be selected at once.
Select the appropriate digital input condition that suits the characteristics of the
external device. “high”, “low” selects level-triggering via external voltage input.

condition can be selected at once. While choosing to trig ger an output alarm, the
digital output will short both pins and complete the external device’s circuit. The
normal state is open. Either email or FTP can be used to command uploading
snapshots. The date and time suffix may also be added as an option. Confirm the
external mail or FTP server settings in the network configuration.
“Reset output” Select and save this option to reset the external device at the digital
output to return to the original state.
Sequential Operation
“Snapshot interval” The Network Camera will send snapshots at the specified intervals to the external server.
“Send snapshots by email” This selects the uploading method following the
intervals set above. The snapshot will be attached in the email with the subject title
“Periodic snapshots”.
“Send snapshots by FTP” The snapshots will be uploaded to the external FTP
server with the file name defined in the next option. This can also be used to refresh
the captured images stored in the external web server to build creative homepages.
“FTP put snapshots with date and time suffix” This option sets up the snapshot
capture date and time, which can be used to easily differentiate the snapshot file
names in either the sequential or event operation. Please check naming rule of
snapshot file for more detail.

Q What if I forget my password?
A After the Administrator's password has been assigned, every access to the Network
Camera needs authentication. If you are one of the managed users, you have to ask
the Administrator for the password. If you are the Administrator, there is no way to
recover the root password except by restoring the factory default settings. Refer to
Appendix A for the procedures.
Q Why can I not watch video from the Network Camera after it is authenticated?
A There are many possible scenarios regarding this problem,
1. If you have just ins talled the Netw ork Camer a and are unable to w atch the vi deo,
check if the heartbeat LED is blinking or the lens cap is off. If the heartbeat LED is dim,
perform the software installation again.
2. If the Network Camera is well installed and you are accessing the Network Camera
for the first time using Internet Explorer , adjust the security level of Internet Explorer
to allow installation of plug-ins.
3. If the problem still exists after adjusting, and the message over the image window
is showing "connecting", the network traffic may be too crowded.
4. It there is only “A” shown below the image, check the media options in client
settings containing video.
Q What is the plug-in for?
A The plug-in provided by the Network Camera is used to display motion pictures and
audio in Internet Explorer. If your system does not allow installation of any plug-in
software, the security level of the web browser may need to be lowered. It is
recommended that you consult your network supervisors in your office regarding
adjustment of the security level. Software installation may be regulated in some
offices.
Q Why is the timestamp different from the system time of my PC or notebook?
A The timestamp is based on the system time of the Network Camera. It is
maintained by a real-time clock insi de and can be automaticall y synchronized with
the time-server if the Network Camera is connected to the Internet and the function
is enabled. Differences of several hours may result from the time zone setting.
Q Can I install it on ceiling?
A Yes. There are flip and mirror options in video configuration page to correct the
images for upside down installation.
Q The image is not clear enough.
A Rotate the lens to adjust the focus after the Network Camera has been installed in
the proper position. The image settings and white balance can be fine tuned to
achieve the best visual effect. Also notice the power line frequency must match the
local utility to synchronize and minimize the effect of flickering florescent lights.
Q Why does the image not refresh regularly?
A Some anti-virus programs filter the received web content. It takes time to perform
data examination and affect the streaming application such as that of Network
Camera. However, it only affects the HTTP mode of Network Camera. If the network
allows only HTTP mode, disable the web filtering function of the anti-virus program
temporarily. During this period, the User should be aware of the risk of malicious
network activity.
Q I have opened motion detection windows but it cannot work.
A If the motion detection windows are set up and names are given, check to see if the
function is checked on the first line. While it is enabled, adjust the sensitivity and
percentage to monitor the level indicator for best results.
Q I cannot hear any sound while watching.
A If there is "V" shown below the image, check the sound card in your PC and make
sure media options in client settings cont aining audio. If "AV" is shown, check the
audio source of the Network Camera, make sure you are using internal or external
microphone.
Q How many users are allowed to watch the Network Camera at the same time?
A T oo many users requesting the real-time multimedia content will jam the network.
For best results, the Network Camera is designed to accommodate a maximum of ten
(10) users to watch and listen for streaming video and audio at the same time. For a
larger number of users, it is recommended to build another web se rver to host the
retrieved contents from the Network Camera.
Q How fast is the video rate of the Network Camera?
A The MPEG4 codec engine can process up to 30 frames per second internally.
However the total performance is subject to many coefficients such as:
1. Network throughput,
2. Bandwidth share,
3. Number of users,
4. The complicated/detailed objects and movement in view,
5. The power of your PC or notebook that is responsible for displaying images.
In general, the transfer rate in a general local network environment can achieve over
200 kilobytes per second and approxima tely 10 to 20 pictures per second from a
regular environment.
Q How can I keep the Network Camera as private as possible?
A The Network Camera is designed for surveillance purposes and has m any flexible
interfaces. The user authentication and special confirmation in installation can keep
the Network Camera from unauthorized access. You may also change the HTTP port
to a non-public number. The demo accoun t is good to separate guests from normal
users and thus you can easily block guests anytime. You can check the system log to
examine any abnormal activities and trace the origins.
Q Why can I not access the Network Camera when I setup some options in the
application?
A Since the Netw ork Camera is a "network camera", any incorrect network settin gs
will make it inaccessible. If this happens, restore the factory default settings following
the procedures in Appendix A.
For some customers who already have their own web site or web control application,
Network Camera can be easily integrated through convenient URLs. This section lists
the commands in URL format corresponding to the basic functions of Network
Camera.
Overview
This section specifies the external HTTP based application programming interface.
The HTTP based camera interface provides the functionality to request a single image,
to control camera functions (output relay etc.) and to get and set internal parameter
values. The image and CGI-requests are handled by the built in Web server.
Style convention
In URL syntax and in descriptions of CGI parameters, a text in italic within angle
brackets denotes a content that is to be replaced with either a value or a string. When
replacing the text string also the angle brackets shall be replaced. An example of this
is the description of the name for the server, denoted with <servername> in the URL
syntax description below, that is replaced with the string myserver in the URL syntax
example, also below.
URL syntax' are written with the “Syntax:" word written in bold face followed by a
box with the referred syntax as seen below. The name of the server is written as
<servername>. This is intended to be replaced with the name of the actual server.
This can either be a name, e.g., "mywebcam" or "thecam.adomain.net" or the
associated IP number for the server, e.g., 192.168.0.220.
Description of returned data is written with "Return:" in bold face followed by the
returned data in a box. All data returned as HTTP formatted, i.e., starting with the
string HTTP is line separated with a Carriage Return and Line Feed (CRLF) printed as
\r\n.
Return:
HTTP/1.0 <HTTP code> <HTTP text>\r\n
URL syntax examples are written with "Example:" in bold face followed by a short
description and a light grey box with the example.
Example: request a single snapshot image
http://mywebserver/cgi-bin/video.jpg
General CGI URL syntax and parameters
CGI parameters are written in lower-case and as one word without any underscores
or other separators. When the CGI request includes internal camera parameters, the
internal parameters must be written exactly as they are named in the camera or
video server. The CGIs are organized in function related directories under the cgi-bin
directory. The file extension of the CGI is required.
Syntax:
http://<servername>/cgi-bin/<subdir>[/<subdir>...]/<cgi>.<ext>
[?<parameter>=<value>[&<parameter>=<value>...]]
Example: Setting digital output #1 to high
http://mywebserver/cgi-bin/setparam.cgi?do1=h
Get server parameter values
Note: This request require administrator access
Method: GET/POST
where the <parameter> should be <group>[_<name>] or <group>[.<name>] If
you do not specify the any parameters, all the parameters on the server will be
returned. If you specify only <group>, the parameters of related group will be
returned.
When query parameter values, the current parameter value are returned.
Successful control requests returns paramter pairs as follows.
Return:
