Hardware Installation

Please verify that your product package contains all the accessories listed in the foregoing Package Contents. Depending of 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 IT750 (IT750W/IT750W-LR) 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 IT750 (IT750W/IT750W-LR) 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 red LED of the Network Camera will flash every second. Until the Network Camera is connected to the other wireless device, the red LED will become lighted. Operating in either network mode, the green LED will flash every second as heartbeat to indicate alive.

To install in Ethernet

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.

To install in wireless LAN (for IT750W and IT750W-LR wireless models only)

If the Ethernet is not available while power on, the IT750W (IT750W-LR) Network Camera will search for any access point with the SSID “default”. Once any access point is found, the LED will turn green to wait for installation. If the network environment cannot meet the default settings, install Network Camera in Ethernet to proceed with wireless LAN configuration.

The IT750 (IT750W/IT750W-LR) 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)

(close with SW_OPEN when set DO to ON)

4 SW_NOPEN OUTPUT (Max. 1A, 24VDC or 0.5A, 125VAC)

Software Installation

In this manual, "User" refers to whoever has access to the IT750 (IT750W/IT750W-LR) Network Camera, and "Administrator" refers to the person who can configure the IT750 (IT750W/IT750W-LR) 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 “Network Camera Wizard” item, after the window contains changed, click on “Installation Wizard” to run installation program.

Upon Installation Wizard’s start up, a searching box will pop up. This program searches for product on the same LAN:

After searching, 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 the bottom of the IT750 (IT750W/IT750W-LR) 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 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 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 new UPnP function will always assign an IP address for the IT750 (IT750W/IT750W-LR) 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 more detailed usage of the Installation Wizard, please refer to the user’s manual of the Installation Wizard.

Initial Access to the Network Camera

Installing Plug-in

For the initial access to the IT750 (IT750W/IT750W-LR) 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 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.

Check Network Settings

The IT750 (IT750W/IT750W-LR) 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 IT750 (IT750W/IT750W-LR) 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 IT750 (IT750W/IT750W-LR) 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.

How to Use

Authentication

After opening the web browser and typing in the URL of the IT750 (IT750W/IT750W-LR) 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.

“Configuration” Only the Administrator can access camera configurations.

The camera view

The information bar down of the IT750 (IT750W/IT750W-LR) camera view shows the assigned caption and the current date/time. The information bar at the bottom of the IT750 (IT750W/IT750W-LR) 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.

The camera view provides not only the live video, but also a way to aim the Network Camera to different target. Using mouse to click on the target inside the video will command the Network Camera to aim at the target and with the mouse wheel up or down, the camera view will zoom out or in.

The pan/tilt/zoom control buttons:

The direction buttons are for Left, Right, Up, Down, and Home functions. The Home button centers the camera.

“Go to” Once the Administrator has determined the preset positions; the User can aim the camera using this control.

“Pan speed”

This selection box sets the moving range of the “Left” and “Right” commands.

“Tilt speed”

This selection box sets the moving range of the “Up” and “Down” commands.

“Zoom speed”

This selection box sets the moving range of the “zoom in” and “zoom out” commands.

“Stop” This stops the “Auto Pan” command or “Auto Patrol” command.

The CCD control buttons:

The set of the buttons is for controlling focus, iris and zooming.

Client Settings

There are four settings for the client side.

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 audio 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 à HTTP. After the IT750 (IT750W/IT750W-LR) 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 update the JPEG image from server 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”.

Administrator’s Capabilities

Fine-tuning for Best Performance

There are a few choices the Administrator is allowed to maximize the capabilities of the IT750 (IT750W/IT750W-LR) 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 Configuration page à Video, 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 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 slow 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. Try 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

To 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.

Somewhere Between Real-time and Clear Images

If you have a broadband network, set “Fix quality” at ”Normal” or better, rather than setting “Fix bit rate”. You 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 IT750 (IT750W/IT750W-LR) Network Camera with Pan/Tilt/Zoom is a camera with dual video codec, they’re MPEG4 and MJPEG. 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 video quality and contents. Together with the frame rate selected, the administrator can control the bandwidth of each connection.

Opening Accounts for New Users

Protect Network Camera by Passwords

The IT750 (IT750W/IT750W-LR) 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. Type 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 IT750 (IT750W/IT750W-LR) 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 account has four kinds of privileges, which can be set individually. The “I/O access” privilege permits the user to access DI/DO of the server. The “Camera Control” privilege allows different control to pan/tilt functions of the Network Camera. The “Talk” privilege permits the user to send speech to the IT750 (IT750W/IT750W-LR) 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 IT750 (IT750W/IT750W-LR) 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 IT750 (IT750W/IT750W-LR) Network Camera can allow the "overload" viewers to see the snapshots in JPEG mode, on the homepage. These 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 IT750 (IT750W/IT750W-LR) Network Camera.

If the web space has FTP service

Set the Network Camera up as an FTP client to upload the pictures. The access to the IT750 (IT750W/IT750W-LR)Network Camera will be independent of the number of viewers and the picture quality will remain constant.

1. Click on “Configuration” on the homepage,

2. Click on “Mail & FTP” in the left column,

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 IT750 (IT750W/IT750W-LR) 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 IT750 (IT750W/IT750W-LR) 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 IT750 (IT750W/IT750W-LR) Network Camera and slows the response.

Example of an auto-refresh web page:

"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 IT750 (IT750W/IT750W-LR) Network Camera starts. Therefore, once the network settings, especially the IP address, have been entered correctly, select “Use fixed IP address” then the IT750 (IT750W/IT750W-LR) 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 IT750 (IT750W/IT750W-LR) 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

“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.

< NetworkCamera > is the domain name or original IP address of the IT750 (IT750W/IT750W-LR) Network Camera.

Video Codec Parameters

“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 the 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. To 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.

Image Settings

Click on “Image Settings” to pop up another window for tuning "Brightness", “Contrast”, “Hue” and "Saturation" for video compensation.

Each field has eleven levels ranged from -5 to +5. The User may press “Preview” to fine-tune the image. When the image is O.K., press “Save” to set the image settings. Click on “Restore” to recall the original settings without incorporating the changes.

CCD Settings

Click on “CCD Settings” button, the CCD settings window will pop up.

The default setting of the CCD is of auto-IRIS mode. Therefore the “Auto electronic shutter” (AES) option will be fixed at 1/60 (1/50) second. Once the shutter is selected as “Auto”, the IRIS of the CCD will become fixed. There are several selectable items for AES. Faster electronic shutter helps seeing fast moving objects more clearly.

“Auto tracking white balance” is usually applied when the Network Camera is aiming outdoor. Adjusting the 9 levels of white levels can help the camera capturing video with correct colors. On the other hand, select “White balance control” will disable “Auto tracking white balance”. It is usually applied indoor to adjust the video colors. The administrator can set different color temperatures (3200K~8000K) to get correct colors.

Checking “Low lux mode” helps seeing object in poor illuminative environment.

Turning on “Auto switch to B/W in low lux mode” together with “Low lux mode” being checked, the video will become black and white automatically if the camera is aiming at dark environment.

“Enable BLC” option is for back light compensation. Normally, objects in front of light source are difficult to be seen, checking this option and adjusting “BLC sens level” can help seeing the objects more clearly. The BLC sens level is about sensitivity of BLC detection.

Clicking on “BLC Area Selection”, a selecting window will pop up. As the window shows, the video is divided to 48 rectangle areas with the same size. Select the areas to enable BLC, if no area is selected, checking “Enable BLC” option makes the video no differences.

The picture illustrates the corresponding areas of the selecting window in the real video. “Select All” will check all the areas in the windows and “Clear All” will do vice versa. “Save” button can set the selected areas for BLC.

In the CCD settings window, click on “Preview” to see the effect of changing the options. Click on “Save” to set the CCD settings. Click on “Restore” to recall the original settings without incorporating the changes.

Audio

“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 IT750 (IT750W/IT750W-LR) 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 prevent 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.

“Zoom speed” This controls the range of the zooming. The greater the value, the greater viewing angle changed.

“Focus speed” This controls the range of the focus adjustment. The greater the value, the greater adjustment.

“Auto pan/patrol speed” This defines the speed of panning and patrol, the greater the value, the faster the speed.

2. Preset function area

“Current position” If the User wants to save the current view as a preset location, enters a name for each of the current video view at “Current position” and click on the “Add” button. The camera allows for ten preset locations.

The preset function is valid only in optical zoom mode.

“Preset position” This keeps a list for preset positions. Clicking on the “Delete” button will remove the current selected position from the preset list.

“Set as home” Click on the button will command the IT750 (IT750W/IT750W-LR) Network Camera to set the current aiming position as Home position. That is: when user click on the “Home” control in Camera control area or after the Network Camera rebooted, the aiming area will be moved to the current position.

“Default home” Click on the button will restore the “Home” definition to the original position.

“Dwelling time” The value set here specifies:

1. The stop time of each preset location during auto patrol of the IT750 (IT750W/IT750W-LR) Network Camera.

2. The stay time at the most left and the most right positions when the IT750 (IT750W/IT750W-LR) Network Camera is doing auto panning.

“Enable IR control” Checking this box allows the Administrator to enable the IR controller to move the aim of the camera. To allow controls only through URL commands or web pages, leave this box unchecked.

“Zoom times display” Checking this box allows the Administrator to display the zoom magnitude on the transmitted video. The information is described as the following table:

Text displayed	Meanings
Zoom X3	3 times optical zoom, the focal lens equals to 12.6 mm.
Zoom X10 xE2	10 times optical zoom with 2 times digital zoom, the focal lens equals to 84 mm.

“Patrol selection” After the User has saved a list of preset positions, the “Preset locations” box will also keep a list of the preset positions. And once the “Select>” button is clicked, the “Selected location” box will keep a list of the patrol stops. The “Remove” button removes the preset position from the patrol stops. The “UP”, “DOWN” buttons adjust the order of the patrol stops. Several preset positions can be added to the patrol stops. The camera can accept up to 20 patrol stops.

“Save” button is valid for “Pan speed”, “Tilt speed”, “Tilt speed”, “Auto pan/patrol speed”, “Enable IR control”, “Dwelling time” and “Patrol selections”. In other words, after changing these settings, and the “Save” button is not clicked, the new setting of the camera will not take effect.

B. Frequently Asked Questions

Q What if I forget my password?

A After the Administrator's password has been assigned, every access to the IT750 (IT750W/IT750W-LR) 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 IT750 (IT750W/IT750W-LR) Network Camera after it is authenticated?

A There are many possible scenarios regarding this problem,

1. If you have just installed the IT750 (IT750W/IT750W-LR) Network Camera and are unable to watch the video, 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 IT750 (IT750W/IT750W-LR) Network Camera is well installed and you are accessing the IT750 (IT750W/IT750W-LR) 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 IT750 (IT750W/IT750W-LR) 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 IT750 (IT750W/IT750W-LR) Network Camera. It is maintained by a real-time clock inside and can be automatically synchronized with the time-server if the IT750 (IT750W/IT750W-LR) 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?

For best results, the IT750 (IT750W/IT750W-LR) 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 server to host the retrieved contents from the IT750 (IT750W/IT750W-LR) Network Camera.

Q How fast is the video rate of the IT750 (IT750W/IT750W-LR) 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 approximately 10 to 20 pictures per second from a regular environment.

Q How can I keep the IT750 (IT750W/IT750W-LR) Network Camera as private as possible?

A The Network Camera is designed for surveillance purposes and has many flexible interfaces.
