Frame Rate:
the number of compressed frames produced by camera per
second.
The bigger the frame is, the better the image continuity will be, but the CPU
performance is lowered.
The smaller the frame is, the worse the image continuity will be, but the CPU
could handle more events.
The maximum frame rate for H.264 is 30fps. The maximum frame rate for
MJPEG is 10fps.
Note: the video settings of H.264 major/minor stream are linkage with that of
MJPEG stream. If H.264 major stream is set to 720P/30fps, minor stream
closed, MJPEG is only able to set to 720P/4fps. If H.264 major stream is set to
720P/25fps, minor stream closed, MJPEG frame is able to set to 10fps. Do
operate according to the prompt on the page.
GOV number:
GOV number means the ratio of I frame to P frame in compressed
video images.
The bigger the value is, the less the data quantity is and the less network
resource it occupies.
Max.
GOV number
can be set to 60.
Bit Rate:
There are 2 modes of bit rate: variable rate (vbr) and constant rate
(cbr).
The variable rate can adjust the bandwidth that it occupies automatically
according to the complexity of image, because the complexity of real video
sequence keeps changing, details, speed, etc, and the variable rate setting mode
