Chapter 3 Configuring and Managing the IP Camera
Audio/Video Windows
Video Quality Control
Choose an option for the video quality of the primary 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 4 Mbps. A
higher bit rate provides better video quality but consumes more
bandwidth.
•
Fixed Quality
—Specifies that video is output at a fixed quality, which
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.
You can use these options to help manage bandwidth use in your network.
For example, if the IP camera is focused on an area with little movement,
such as an emergency exit, you can configure it with a low fixed quality.
Max. Frame Rate
Choose the desired maximum frame rate per second for the primary video
stream from the IP camera.
The default values are 30 for NTSC and 25 for PAL.
A higher maximum frame rate provides better video quality but consumes
more bandwidth
