9.1.4 Bitrate Type and Max. Bitrate
Constant Bitrate
It means that the stream is compressed and transmied at a comparavely xed bitrate. The
compression speed is fast, but mosaic may occur on the image.
Variable Bitrate
It means that the device automacally adjust the bitrate under the set Max. Bitrate. The
compression speed is slower than that of the constant bitrate. But it guarantees the image
quality of complex scenes.
9.1.5 Video Quality
When Bitrate Type is set as Variable, video quality is congurable. Select a video quality according
to actual needs. Note that higher video quality requires higher bandwidth.
9.1.6 Frame Rate
The frame rate is to describe the frequency at which the video stream is updated and it is
measured by frames per second (fps).
A higher frame rate is advantageous when there is movement in the video stream, as it maintains
image quality throughout. Note that higher frame rate requires higher bandwidth and larger
storage space.
9.1.7 Video Encoding
It stands for the compression standard the device adopts for video encoding.
Note
Available compression standards vary according to device models.
H.264
H.264, also known as MPEG-4 Part 10, Advanced Video Coding, is a compression standard. Without
compr
essing image quality, it increases compression rao and reduces the size of video le than
MJPEG or MPE
G-4 Part 2.
