Stream failure evidence for the teams that must explain it.
Choose the workflow that matches the audience: field installation, support triage, or camera firmware QA. Each path leads to a failure report, not another generic RTSP explainer.
RTSP failures look similar from the outside: a black screen, a timeout, a player that works while the VMS fails, or a camera that passes ONVIF discovery but cannot deliver usable media. The right use case depends on who must explain the failure and what kind of evidence they need to hand off.
Installers usually need fast proof at the customer site: RTSP URL validity, transport choice, UDP blocking, and whether the camera is producing RTP media. VMS support teams need a repeatable report that separates camera, network, NVR, VMS, codec, and player responsibility. QA teams need reproducible stream evidence before firmware, encoder, or SDP changes leave the lab.
Start with the audience below, then follow the page that matches the job. Each route keeps the same product boundary: RTSP Inspector diagnoses authorized streams and exports evidence; it is not a public camera viewer, surveillance suite, or generic network monitor.
