Section ² - Configuration

“Best performance” means the image refresh rate should be the fastest possible and the video quality should be the

best possible at the lowest network bandwidth possible. Three factors, Maximum frame rate, Fixed bit rate, and Fixed

quality in the Video Configuration page, are related to performance.

Recording settings for real-time motion images

To achieve a real-time visual effect, the network bandwidth should be large enough to transmit 20 image frames per

second (fps) or more. If you are on a broadband network over 1 Mbps, you can set Fixed bit Rate to 1000Kbps or

1200Kbps, or set Fixed quality to achieve the maximum frames. The maximum frame rate is 25 in 50Hz system and

30 in 60Hz system. If your network bandwidth is more than 384Kbps, you can adjust Fixed bit rate according to your

bandwidth and set the maximum frame rate of 25 to 30.

If the images vary dramatically in your environment, you may slow down the maximum frame rate to 20 to decrease

the transmitted data for better video quality. Since the human eye can not easily differentiate between 20 and 25 or 30

frames per second, the slower frame rate will not be noticed. If your network bandwidth is below 384 Kbps, you should

adjust the bit rate according to your bandwidth and experiment to allow for the best frame rate that can be achieved.

The faster frame rate in a slow network will blur the images. You may also try to choose 320x240 in size option for better

images or 640x480 for larger image size. Because the network has burst constraints and everyone’s environment is

different, any poor connection will impair normal performance.

Recording settings for clear identification for each image

To have the best video quality, you should set Fixed quality to detailed or excellent and tune the Maximum frame rate to

suit

your network bandwidth. If you get some broken pictures in a slow network, you can set TCP protocol in Connection

type for a more accurate transmission but the received images may have a lag. Note that any slow connection with

multiple users will impair performance.

Recording settings to compromise between real-time and clear images

If you have a broadband network, set Fixed quality to Good image quality, or higher, instead of setting the Bit rate.

Otherwise, fix the bit rate according to your actual network speed and set the frame rate to 30. If the image quality is

low, select a lower frame rate above 15. If the image quality is still not improved, select a lower bit rate.
