Notes

  • Network checks compare the high estimate with each link: up to 70% is OK, up to 90% is a caution, above that is over capacity.
  • Bitrates marked "~" or "est." are planning estimates; real bitrate varies with scene, night/IR and camera model. Use measured averages or configured bitrate caps for the most reliable results.
  • The bitrate and sub-stream estimates currently use preliminary placeholder values that have not been validated against measured cameras.
