Click the “Audio” tab to go to the interface as shown below.
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+, H264, H265+ or H265 can be optional. If H.265/H.265+ is chosen, make sure the client system is able to
decode H.265/H.265+.
Profile: For H.264. Baseline, main and high profiles are selectable.
Send Snapshot: How many snapshots to generate for an event.
Video encode slice split: If this function is enabled, smooth image can be gotten even though using the low-performance PC.
Watermark: When playing back the local recorded video in the search interface, the watermark can be displayed. To enable it, check
the watermark box and enter the watermark text.
Audio Encoding: G711A and G711U are selectable.
Audio Type: LIN. Some models may support MIC type.
