Network Camera User Manual
Click “Audio” tab to go to the interface as shown below.
Three video streams can be adjustable.
Resolution
: The higher the resolution is, the clearer the image is.
Frame rate
: The higher the frame rate is, the more fluency the video is. However, more
storage room will be taken up.
Bitrate type
: Including CBR and VBR. CBR means that no matter how changeable the video
resources are, the compression bitrate keeps constant. This will not only facilitate the image
quality better in a constant bitrate but also help to calculate the capacity of the recording.
VBR means that the compression bitrate can be adjustable according to the change of the
video resources. This will help to optimize the network bandwidth.
Bitrate
: Please choose it according to the actual network situation.
Video Quality
: When VBR is selected, you need to choose image quality. The higher the
image quality you choose, the more bitrate will be required.
I Frame interval
: It is recommended to use the default value. If the value is over high, the
read speed of the group of pictures will be slow resulting in the quality loss of the video.
Video Compression:
H264 and H265 are optional. Higher quality of image can be transferred
under limited network bandwidth by using H265 video encoding, however, higher quality of
the hardware is required.
Profile
: Baseline, main/high profiles are optional. Baseline profile is mainly used in
interactive application with low complexity and delay. Main/high profile is mainly used for
higher coding requirement.
Send Snapshot
: Please select it according to the actual situation.
Video encode slice split
: If enabled, you may get more fluency image even though using the
low-performance PC.
Watermark
: If enabled, input the watermark content. You may check the watermark when
playing back the local record in the search interface, lest the record files is tampered.
Audio Encoding
: G711A and G711U are selectable.
Audio Type
: MIC and LIN are selectable.
