Section 3: Configuration
Constant Bit If the Rate Control is set to CBR, you can set the bit rate to use for this video
Rate: profile.
If the Rate Control is set to CVBR, you can set the maximum bit rate this
Max Bit Rate:
video profile can use.
Fixed Quality: Select the image quality level for the camera to try to maintain. High quality
levels will result in increased bit rates and use more bandwidth.
Intra frame This sets the period (in seconds) between each full-image frame for the
period: compression algorithm selected; this setting is only configurable for H.264
and H.265, as MJPEG uses the full image for every frame. A general rule of
thumb is the lower that number, the better the image but the higher the
bandwidth and storage requirements.
