Administrator’s Capabilities
Fine-tuning for Best Performance
There are a few choices the Administrator is allowed to maximize the capabilities of the
Network Camera. Best performance generally equates to the fastest image refresh rate
with the best video quality, and at the lo west 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 Video Configuration page, are correlative to allow for
achieving the best performance possible.
For Best Real-time Video Images
To achieve good real-time visual effect, th e 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.
