11.1.4 Bitrate Type and Max. Bitrate

Constant Bitrate
It means that the stream is compressed and transmitted at a comparatively fixed bitrate. The
compression speed is fast, but mosaic may occur on the image.
Variable Bitrate
It means that the device automatically 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.

11.1.5 Video Quality

When Bitrate Type is set as Variable, video quality is configurable. Select a video quality according
to actual needs. Note that higher video quality requires higher bandwidth.

11.1.6 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.

11.1.7 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 compressing image quality, it increases compression ratio and reduces the size of video
file than MJPEG or MPEG-4 Part 2.
H.264+
H.264+ is an improved compression coding technology based on H.264. By enabling H.264+, you
