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 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-time Video Images

To achieve good real-time visual 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 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
