Network Camera User Manual
Three video streams can be adjustable.
Resolution
: The size of image.
Frame rate
: The higher the frame rate, the video is smoother.
Bitrate type
: CBR and VBR are optional. Bitrate is related to image quality. CBR means that
no matter how much change is seen in the video scene, the compression bitrate will be kept
constant. VBR means that the compression bitrate will be adjusted according to scene changes.
For example, for scenes that do not have much movement, the bitrate will be kept at a lower
value. This can help optimize the network bandwidth usage.
Bitrate
: it can be adjusted when the mode is set to CBR. The higher the bitrate, the better the
image quality will be.
Video Quality
: It can be adjusted when the mode is set to VBR. The higher the image quality,
the more bitrate will be required.
I Frame interval
: It determines how many frames are allowed between a “group of pictures”.
When a new scene begins in a video, until that scene ends, the entire group of frames (or
pictures) can be considered as a group of pictures. If there is not much movement in the scene,
setting the value higher than the frame rate is fine, potentially resulting in less bandwidth
usage. However, if the value is set too high, and there is a high frequency of movement in the
video, there is a risk of frame skipping.
Video Compression:
H264 and H265 are optional. If H.265 is chosen, make sure the client
system is able to decode H.265.
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
: How many snapshots to generate for an event.
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.
Click the “Audio” tab to go to the interface as shown below.
Audio Encoding
: G711A and G711U are selectable.
Audio Type
: MIC.
