User Manual of Network Camera
2. Select the Stream Type of the camera to main stream (normal) or sub-stream.
The main stream is usually for recording and live viewing with good bandwidth,
and the sub-stream can be used for live viewing when the bandwidth is limited.
Refer to the Section 6.1 Configuring Local Parameters for switching the main
stream and sub-stream for live viewing.
3. You can customize the following parameters for the selected main stream or
sub-stream:
Video Type:
Select the stream type to video stream, or video & audio composite stream. The
audio signal will be recorded only when the Video Type is Video & Audio.
Resolution:
Select the resolution of the video output.
Bitrate Type:
Select the bitrate type to constant or variable.
Video Quality:
When bitrate type is selected as Variable, 6 levels of video quality are selectable.
Frame Rate:
Set the frame rate to 1/16 to 25 fps. 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.
Max. Bitrate:
Set the max. bitrate to 32 to 16384 Kbps. The higher value corresponds to the
higher video quality, but the higher bandwidth is required.
Video Encoding:
When the Stream Type of the camera is main stream, the Video Encoding
standard can be set to H.264.
When the Stream Type of the camera is sub-stream, the Video Encoding standard
can be set to H.264, MJPEG.
