Compression: Video encode mode.
H.264: Main Profile encode mode.
H.264H: High Profile encode mode.
H.264B: Baseline Profile encode mode.
H.265: Main Profile encode mode.
MJPEG: System needs high bit streams to guarantee video definition. Use the
recommended max bit stream value to get the better video effect.
Smart Codec: This function is to reduce bit streams.
Note
Some series products support smart codec function.
After changing smart code, please reboot network camera and some network camera
functions (such as IVS, ROI, SVC, lobby mode and etc.) becomes null. Please think twice
before the operation.
Resolution: The resolution here refers to the capability of the network camera.
Note
Different series products support different resolutions. Please refer to the actual interface for
detailed information.
Frame rate (FPS): The video frame amount displayed in each second. The higher the frame
rate is, the clearer and more fluent the video is. The frame rate may vary depending on the
resolution.
Bit rate type: System supports two types: CBR and VBR.
Main stream: It is to set frame rate to change video quality. The higher the frame rate is,
the better the video quality is. The referenced bit rate is the recommended value.
Sub stream: In CBR mode, the bit stream is near the specified value. In VBR mode, the
video quality changes according to the bit stream value. But its max value is near the
specified value. Reference bit rate: The reference bit rate depends on the resolution and
frame rate you set.
Video/audio: You can enable or disable the video/audio. The main stream is enabled by
default. After enable the audio function, the record file is composite file consisting of the
video and audio. For the sub stream 1, please enable video first and then enable audio
function.
Audio format: Set audio encode format.
Note
Different series products support different audio encode mode. Please refer to the actual
interface for detailed information.
Sampling rate: Audio sampling rate refers to the sampling amount within 1 second. The
higher the value is, the better the audio is. The default setup is 8K.
Copy: After you complete the setup, you can click Copy button to copy current setup to
other channel(s). You can see an interface is shown as in Figure 4-52. You can see current
channel number is grey. Please check the number to select the channel or you can check the
box ALL. Please click the OK button in Figure 4-52 and Figure 4-50 respectively to complete
the setup. Please note, once you check the All box, you set same encode setup for all
channels. Audio/video enable box, overlay button and the copy button is shield.
