Name Function
(6) Frame Rate
Select frame rate per second of video
(7) Intra Frame Period
Select frame internal time period.
(8) Code Type
Select the type of video compression codec. The supported codec is
H.264, MPEG4, and MJPEG. On each stream, adjust rate control and
video quality setting.
VBR (Variable Bit Rate): by default use this setting if there is a need to
maintain the image quality whenever there is lot of activities on the
scene or no motion. This setting keeps the video stream constant as
possible which increases the bandwidth requirement when there is high
motion and decreases when there is no motion. The bandwidth must be
able to accommodate high throughputs.
CBR (Constant Bit Rate): use this setting if there is bandwidth
concern. This setting is restricted to keep the bit rate setting. This could
affect the image quality and frame rate if there is high activity that result
in a bit rate that is higher than the set bit rate.
