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.

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.
