Description
ID of the video output channel.
The device supports three streams.
 Streams 1 and 2 use the H.264 codec.

Stream 3 uses the Motion Joint Photographic
Experts Group (MJPEG) codec.

The maximum resolution can be set for streams 1
and 3.

Only a low resolution can be set for stream 2.
Stream name.
NOTE
The stream name is combined with number, character and
underline.
As a key parameter for a high definition (HD) IP
camera, 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 High Profile, H.264 Main
Profile, and H.264 Base profile. H.264 introduces a
codec based on IP packets. It supports packet
transmission, video stream transmission, and
different codec levels based on network resources.
H.264 features high and stable image quality, high
compression ratio, and good network suitability.
