Select the resolution of the video output.
Bitrate Type:

Frame Rate:
Set the frame rate. The frame rate is to describe the frequency at which the video
stream is updated and it is measured by frames per second (fps). A higher frame
rate is advantageous when there is movement in the video stream, as it maintains
image quality throughout.

Set the max. bitrate from 32 to 16384 Kbps. The higher value corresponds to the
higher video quality, but the better bandwidth is required.
Note: The maximum limit of the max. bitrate value varies according to different
camera platforms. For certain cameras, the maximum limit is 8192 Kbps or 12288
Kbps.
