Video Quality Control
Choose an option for video quality for the secondary video stream from the
IP camera:
•
Constant Bit Rate—Specifies that the video stream is output at or close
to the constant bit rate that you choose. The default value is 1.2 Mbps.

ranges from Very High to Very Low. The bit rate may vary to maintain
this quality. The default fixed quality is Normal. A higher fixed quality
provides better video quality but consumes more bandwidth.
