Multiple video streams can be adjustable.
Resolution: The size of the 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: MJPEG, H264+, H264, H265 or H265+ can be optional.
MJPEG is not available for main stream. If H.265/H.265+is chosen, make sure the
client system can decode H.265/H.265+. Compared to H.265, H.265+ saves more
storage space with the same maximum bitrate in most scenes. Compared to H.264,
H.265 reduces the transmission bitrate under the same resolution, frame rate and
image quality.
Note: Some models may support H264S (Smart H.264)/H265S(Smart H.265).
Compared to H.265+/H.265, smart H.265 can spontaneously adjust the bitrate
distribution according to the requirements of the actual scene. For example, when
there is no human or vehicle detected, the bitrate will be automatically reduced with no
effect on image quality by using H.265S.
SVC：Only some models support this function. Scalable Video Coding (SVC) is able to
extract one or more subset bit streams with different frame rates from a bit stream.
Profile: For H.264. Baseline, main and high profiles are selectable.
