3.4.1 Video Settings
Users can set the video parameters in the format of H.265/H.264/MJPEG main or sub stream
and MJPEG.
Enctype
: H.264/H.265/MJPEG
Resolution
: For main stream, the resolution of IP camera comes up to 1920X1080, with 1280X960,
1280X720, 720X576, 720X480 optional; For sub stream, the resolution comes up to 720X480, with
640X480,480X360,352X288, 320X240,176X144 optional. For MJPEG stream, the resolution comes
to 1920X1080, 1280X720.
Video type : complex stream, video stream
Profile : Baseline, main, high
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 is 30fps.
I/P Rate : I/P rate 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. I/P
rate can be set to 120.
Bitrate type : 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 can be used to choose how much bandwidth should be used. If the
video gets more details and moving fast, then it takes up more bandwidth to transmit, and
reversely it occupies less bandwidth. When the setting goes with constant bit rate, then the image
is transmitted under a constant bandwidth.
