Three video streams can be adjusted.
Resolution: Adjusts the camera stream resolution.
Frame rate: Adjusts image FPS (frames per second). A high frame rate results in
a smoother video.
Bitrate type:
• CBR: constant bitrate; compression bitrate is kept constant and allows video
quality to vary.
• VBR: variable bitrate; compression bitrate will be adjusted according to
scene changes. For example, for scenes that do not have much movement,
the bitrate will be kept at a lower value. This can help optimize network
bandwidth usage.
Bitrate: (CBR must be enabled); determines processing power for video
streaming where higher bitrate results in better image quality.
Video Quality: (VBR must be enabled); The higher the image quality, the more
bitrate will be required.
I-Frame interval: Determines how many partial frames (P-frames) may be
inserted between full frames (group of pictures) in the video stream. If there is
not much movement in the scene, setting the value higher than the frame rate
may potentially result in less bandwidth usage. However, if the value is set too
high and there is a high frequency of movement in the video there is a risk of
frame skipping.
Video Compression: Determines max data rate and video resolution for a video
stream. Select H.264, H.265, or MJPEG (unavailable for the Main stream)
