How to Use

Authentication

After opening the Web browser and typing in the URL of the Network Camera, a dialogue window pops up to request a username and password. Upon successful authentication, the following figure is displayed.

The foreground is the login window and the background shows the message if authentication fails. The user may check the option box to save the password for future convenience. This option is not available to the Administrator for obvious reason.

Installing plug-in

For the initial access to the Network Camera in Windows, the web browser may prompt for permission to install a new plug-infor the Network Camera. 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. Thisplug-inhas been registered for certificate and is used to display the video in the browser. Users may click onto proceed. If the web browser does not allow the user to continue to install, check the Internet security option to lower the security levels or contact your IT or networking supervisor for help.

Click on the magnifier icon under the camera view then the digital zoom control panel will be shown. Uncheck “Disable digital zoom” and use the slider control to change the zoom factors.

Digital Output

Clicking on the “On” or “Off” button turns the digital output to either on or off status.

Client settings

At the initial access to the “Connection type” page in Windows, the web browser will ask for a new plug-ininstallation, theplug-inbeing the Network Camera. Thisplug-inhas been registered for certification and can be used to change the parameters at the client’s site. The user may click onto install theplug-in.If the web browser does not allow the user to complete the installation, check the Internet security to lower the security level or contact your IT or networking supervisor.

There are two settings for the client side. One is “Media Option” for users to determine if audio should be muted. The other is “Protocol Option” which allows choices on connection protocol between client and server. There are three protocols choices to optimize your usage - UDP, TCP and HTTP.

The UDP protocol allows for more real-timeaudio and video streams. However, some packets may be lost due to network burst traffic and images may be obscured.

The TCP protocol allows for less packet loss and produces a more accurate video display. The downside with this protocol is that the real-timeeffect is worse than that with the

UDP protocol.

The HTTP protocol must be selected if the network is protected by a firewall and it only allows HTTP Port (80) to be opened. In this mode, audio will not be sent and only video is operational. If no special need is required, UDP protocol is recommended. Generally speaking, the client’s choice will be in the order of UDP → TCP → HTTP. After the Network Camera is connected successfully, “Protocol Option” will indicate the selected protocol. The selected protocol will be recorded in the user's PC and will be used for the next connection. If the network environment is changed, or the user wants to let the web browser to detect again, manually select the UDP protocol, save, and return HOME tore-connect.

<url> http://<Network Camera>/protocol.html

<Network Camera> is the domain name or the original IP address of the Network Camera.

Fine-tuningfor Best Performance

Best performance generally equates to the fastest image refresh rate with the best video quality, and at the lowest network bandwidth as possible. The three factors, “Maximum frame rate”, “Fix bit rate”, and “Fix quality” on the Video Configuration page, are correlative to allow for achieving the best performance possible.

For Best Real-timeVideo Images

To achieve good real-timevisual 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, and set “Fix quality” at the highest quality. The maximum frame rate is 25 in PAL system and 30 in NTSC 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 the images vary dramatically in your environment, 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-tuningwith the “Maximum frame rate”. In a slow network, greater frame rate results in blur images. Anotherwork-aroundis 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.

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 TCP protocol in “Connection type” and choose a more appropriate mode of transmission. The images may suffer a time delay due to a slower connection. The delay will also increase with added number of users.

Somewhere Between Real-timeand 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.

Opening accounts for new users

Protect Network Camera by passwords

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. Type a new word twice in ○1 to enable protection. This password is used to identify the administrator. Then add an account with user name and password for your friends in ○2 . 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. An option to access DI/DO is provided for each account. Some users may need to prohibit from controlling your attached devices. You may delete some

More flexible options for viewers 4

The first option allows anyone uses “demo” as the user name to view without password. The Administrator can also decide if more viewers are allowed to watch the video if the viewers exceed the limit. The overloaded viewers will have snapshot mode instead.
