Section 4: Configuration
Video Quality: This limits the maximum frame rate, which can be
combined with the "Fixed quality" option to optimize
the bandwidth utilization and video quality. If fixed
bandwidth utilization is desired regardless of the video
quality, choose "Constant bit rate" and select the desired
bandwidth.
Constant bit rate: The bps will affect the bit rate of the video recorded
by the camera. Higher bit rates result in higher video
quality.
Fixed quality: Select the image quality level for the camera to try to
maintain. High quality levels will result in increased bit
rates.
