Parameters of Stream Configuration
Description
The device supports at most three main streams.
Streams 1 and 2 adopt H.264 code.
The maximum resolution can be set for streams
1.
Only a low resolution can be set for stream 2.
Stream 3 is the lowest resolution.
Stream 4 is the sub stream.
Stream name.
NOTE
The stream name consists of Chinese character, number,
character and underline.
The video codec determines the image quality and
network bandwidth required by a video. Currently,
the following codec standards are supported:
MJPEG
MJPEG is a standard intra-frame compression
codec. The compressed image quality is good. No
mosaic is displayed on motion images. MJPEG does
not support proportional compression and requires
large storage space. Recording and network
transmission occupy large hard disk space and
bandwidth. MJPEG is not applicable to continuous
recording for a long period of time or network
transmission of videos. It can be used to send alarm
images.
H.264
H.264 consists of H.264 low Profile, H.264 Main
Profile and H.264 High profile. The performance of
H.264 High Profile is higher than that of H.264
Main Profile, and the performance of H.264 Main
Profile is higher than that of H.264 Base Profile. If a
hardware decoding device is used, select the
appropriate codec based on the decoding
performance of the device.
H.264 High Profile has the highest requirements on
the hardware performance, and H.264 Base Profile
has the lowest requirements for the hardware
performance.
H.265
H.265 is the advanced video encoding standard. It's
the improvement standard from H.264. H.265
improves the streams, encoding quality and
algorithm complexity to make configuration
optimization.

Setting
[Setting method]
Select a value
from the drop-
down list box.
[Setting method]
Enter a value
manually. The
value cannot
exceed 32 bytes.
[Default value]
Stream 1
[Setting method]
Select a value
from the drop-
down list box.
[Default value]
H.264 High
Profile
NOTE
The H.264 High
Profile codec
means high
requirements on
the hardware. If
the hard-decoding
capability is low,
use H.264 Main
Profile or H.264
Base Profile.
When users choose
the MJPEG for
Stream 1, some
functions will be
error, such as the
videos of FTP
upload may not be
play correctly.
