Main Screen with Camera View

Snapshot: Opens a still picture of current view in new window.

Client Settings: Configures local Browser settings.


Provides access to all camera configuration options.

Camera View: Live streaming video.

Digital Zoom

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.

Click on Snapshot, web browser will pop up a new window to show the snapshot. Users can point at the snapshot and click the right mouse button to save it.

Client Settings

There are two settings for the client side:

Media Options to determine the type of media to be streamed and Protocol Optionswhich allows choice of connection protocol between client and server. There are two protocol choices to optimize your usage – UDP and TCP.

- 8 -


The UDP protocol allows for morereal-timeaudio and video streams. However, some packets may be lost due to network burst traffic and images may be obscured. TheTCP protocol allows for less packet loss and produces a more accurate video display. The downside with this protocol is that thereal-timeeffect is worse than that with the UDP protocol. If no special need is required, UDP protocol is recommended. Generally speaking, the client’s choice will be in the order of UDP – TCP.

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 detect again, manually select the UDP protocol, save, and return HOME tore-connect.

Digital Output

Click on ON, the digital output of the Network Camera will be triggered. Or, clicking onOFF can let the digital output turn into normal state.

Administrator’s Capability

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,Constant bit rate, andFix quality on the Audio and Video Configuration page, correlate to allow for achieving the best performance possible.

For Viewing by Mobile Phone

Most 3GPP cell phone supports media streaming with MPEG4 video and GSM-AMRaudio. Due to the limitation of the bandwidth for 3GPP, only 176x144 video solution will be supported for cell phone viewing. Select theConfigure for mobile viewing option will change the range of other related video settings.

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 theFix bit rate to 1000Kbps or 1200Kbps, and setFix quality at the highest quality. The maximum frame rate is 30. If your network bandwidth is more than 512Kbps, you can fix the bit rate according to your bandwidth and set the maximum frame rate to 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 20, 25, or 30 frames per second. If your network bandwidth is below 512 Kbps, set theFix bit rate according to your bandwidth and try to get the best performance byfine-tuningwith theMaximum frame rate. In a slow network, greater frame rate results in blur images. Anotherwork-aroundis to choose160x120 in theSize option for better images. 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 atDetailed orExcellent and adjust theMaximum frame rate to match your network’s bandwidth. If your network is slow and you receive “broken” pictures, go to the TCP protocol inConnection 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 atNormal or better, rather than settingFix 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 . The Network Camera can provide twenty accounts for your valuable customers or friends. You may delete some users from3 .

Build a Security Application

The Administrator can use the built-inmotion detection to monitor any movement and perform many useful security applications. To upload the snapshots, users can choose either email or FTP according to user’s needs. Bothe-mailand FTP use the network settings on the Email and FTP page.

1.Click on Configuration on homepage,

2.Click on Motion detection at the left column,

3.Check Enable motion detection,

4.Click on new to have a new window to monitor video,

5.Type in a name to identify the new window,

6.Use the mouse to click, hold, and drag the window corner to resize or the title bar to move,

7.Fine-tuneusing theSensitivity andPercentage fields to best suit the camera’s environment. HigherSensitivity detects the slighter motion. HigherPercentage discriminates smaller objects,

8.Clicking on Save enables the activity display. Green means the motion in the window is under the watermark set by Administrator and red means it is over the watermark,

9.Click on Application at the left column,

10.Check the weekdays as you need and give the time interval to monitor the motion detection every day,

11.Select the Trigger on Motion detection.

12.Set the delay before detecting next motion to avoid continuous false alarms following the original event,

13.Set the number of pre-eventandpost-eventimages to be uploaded, 14.Check the window name set in step 5,

15.Check the way to upload snapshot. 16.Click on save to validate.

Software Revision Upgrade

Customers can obtain the up-to-datesoftware from the web site of 4XEM. Aneasy-to-useUpgrade Wizard is provided to upgrade the Network Camera with just a few clicks. The upgrade function is opened to the Administrator only. To upgrade the system, follow the procedures below.

1.Download the firmware file from www.4xem.com.

2.Run the Upgrade Wizard and proceed following the prompts. Refer to the instructions of the Upgrade Wizard for details.

3.Or upgrade firmware from HTTP web page directly

3. The whole process will finish in a few minutes and it will automatically restart the system.

If power fails during the writing process of Flash memory, the program in the

memory of the Network Camera may be destroyed permanently. If the Network Camera cannot restart properly, call 4XEM Technical Support.

Only the Administrator can access system configuration. Each category in the left column will be explained in the following pages. The bold texts are the specific phrases on the Option pages. The Administrator may type the URL below the figure to directly enter the frame page of configuration. If the Administrator also wants to set certain options through the URL, read the reference appendix for details.
