Enabling Constant Bit Rate Mode
If you have a limited amount of bandwidth available, you should not set the bit rate for the
camera to be more than the bandwidth available on your network (see
Compression on page
When the Constant Bit Rate mode (CBR) is enabled, the H.264 stream will keep the bit rate
constantly at the level you have set (see
NOT enabled, the compression stream will use a variable bit rate (between 1 kbit/s and the bit
rate you have set), depending on the amount of activity that is occurring in the image. If CBR is
enabled and the compression bit rate is set low, the image quality will be reduced when a lot of
activity occurs in the image.
To enable Constant Bit Rate mode:

Video OCX Protocol Settings
The Video OCX Protocol setting is used to select the Video Streaming Protocol for the camera.
There are various options to transmit streaming video over the network (see

network properties (see

Note
Honeywell recommends that you set your bit rates below the available bandwidth
levels of your network to avoid displaying/recording images at a reduced quality
during moments of high activity.
Navigate to Streaming
