There are two video quality modes:
Fixed rate mode is suitable for use in a network environment that the upload bandwidth is limited.
Please select the appropriate bit-rate according to your network environment. For example, if the
network (upload) bandwidth available for the network camera is 500kbps, 500kbps multiplied 0.8
equals 400kbps (considering 20% overhead).This means that the largest fixed bit-rate should be
set less than 400kbps; setting the bit-rate more than that might cause frame drops. Fixed quality
mode is suitable for use if you want a constant video quality.
If you want the best quality, Please choose the best option. The system will adjust the frame rate to
fit the bandwidth available.
There are 9 options to choose in fixed bit-rate drop-list. The higher the bit-rate, the better the video
quality.
There are 5 options to choose in fixed quality drop-list. The better the video quality, the higher the
bit-rate is produced.
