🧙TIPS:
  1. It is necessary to configure distinct video settings for individual channels. By doing so, it ensures that each channel's video output is customized to meet specific requirements, such as resolution, encoding format, frame rate, or other parameters. Tailoring video settings for each channel allows for optimal performance and compatibility with different devices or display systems.
  2. Lowering the Key Interval (GOP) can improve image quality in certain cases if required.
  3. It's a good practice to set a lower bitrate, such as 500Kbits/s, if your local bandwidth is limited. Lowering the bitrate reduces the amount of data used for streaming video, which can help improve the quality and stability of the stream when network conditions are poor or bandwidth is constrained because too much uploading bandwidth will be occupied.
  4. If it's required to view image directly in ODM(ONVIF Device Manager), it's necessary to disable.
  5. H.264 is supported for Preview/RTMP, and H.265 is supported for both RTSP Pull and Push. For more details, please refer to Preview.
