z
Video Type:
Video codec of the selected video profile.
z
Resolution:
Resolution of the selected video profile.
z
ROI:
Assign the selected profile as a ROI stream or not.
z
Rate Control:
Defines the rate control method of this profile. There are four options: Constant Bit
Rate (CBR), Variable Bit Rate (VBR), Enhanced Constant Bit Rate (ECBR), and
Enhanced Variable Bit Rate (EVBR). For CBR, the video bit rate is between low to
high bandwidth based on different resolutions. User can set the desired bit rate to
match the limitation of bandwidth. For VBR, user should choose the quality level to set
the video quality rather than bit rate. The quality level is between 1 and 100. The
higher value can reach the better quality but of course will consume higher bandwidth.
z
Max Frame Rate:
Defines the targeted frame rate of this profile. For example, set the frame rate to 15
fps, then the image will be updated for 15 frames per second as possible. User need
to set reasonable max frame rate versus video quality under the limited bandwidth.
z
GOP Control:
Defines the Intra/Inter-frame (I/P) ratio of this profile. For example, set the GOP to 30,
then the video stream will have one Intra-frame every 30 frames.
