Based on the demand, user should set the stream type, IP rate,
frame rate, resolution, video quality, bit rate type and max bit rate
properly.
(1) Frame rate: The number of video frame in each second, the
setting range is PAL: 1~25, NTSC: 1~30.
(2) Stream type: The data stream produced after compression of
video signal or audio signal (via signal composition or
individual encoding). Video stream and composite stream are
optional. The composite stream includes video and audio in the
compression stream, while video stream includes video only.
Chose "Composite stream" if need to record the video and
audio, and chose "video stream" if need to record the video
only.
(3) IP rate: The rate of P frame and I frame between 2 I frames.
The setting range is 10~255.
(4) Resolution: The higher resolution will produce higher
definition image. QCIF, CIF, 2CIF and 4CIF are optional.
(5) Quality: It needs to set the image quality when the bit rate is
variable rate. The quality and max bit rate are direct ratio, the
higher quality requires higher max bit rate.
(6) Bit rate type: When the bit rate is fixed rate, this defines the
size of the compression stream.
(7) Max bit rate: Limit the max compression stream of
compression the video if set the bit rate type to variable rate.
Normally the max bit rate and resolution are direction ratio,
the higher resolution requires higher max bit rate, vice versa.
The max bit rate should be based on the site, camera, and
image quality demand.
