Network Camera User Manual
65
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. 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 from 32 to 16384 Kbps. The higher value corresponds to the
higher video quality, but the better bandwidth is required.
Note: The maximum limit of the max. bitrate value varies according to different
camera platforms. For certain cameras, the maximum limit is 8192 Kbps or 12288
Kbps.
Video Encoding:
If the Stream Type is set to main stream, H.264 and H.265 are selectable, and if the
stream type is set to sub stream or third stream, H.264, MJPEG, and H.265 are
selectable. H.265 is a new encoding technology. Compared with H.264, it reduces
the transmission bitrate under the same resolution, frame rate and image quality.
Note: Selectable video encoding types may vary according to different camera
modes.
Max. Average Bitrate:
When you set a maximum bitrate, its corresponding recommended maximum
average bitrate will be shown in the Max. Average Bitrate box. You can also set the
maximum average bitrate manually from 32 Kbps to the value of the set maximum
