The short answer
Check the camera’s ONVIF service and local user before scanning. A device advertised as ONVIF-capable may still ship with the service disabled.
Work through the checks
Identify the camera by model, hardware revision, firmware and MAC address. Keep this inventory separate from passwords; two devices with similar names may expose different protocols.
Check the model manual for an ONVIF service switch and any separate ONVIF account. Use the configured service port; do not assume it equals the RTSP port.
Use the camera’s local protocol account. A cloud app email address is not necessarily a valid RTSP or ONVIF login. Grant only the viewing or control permissions actually needed.
Check both computer time and camera time, including time zone and synchronization settings. ONVIF authentication and event ordering can be affected by clock differences.
What to verify
Run local ONVIF discovery on the intended adapter. Discovery may not cross routed networks; compare the discovered address with a manual connection to the known camera IP.
Sources and scope
AeoCam is available for Windows. Camera settings below describe protocol preparation, not a certification of a particular camera or a promise of every feature in every app version. Check the installed build and the Microsoft Store listing for current availability.
Vendor documents describe the camera or protocol. No physical-camera compatibility test is claimed here. Menus and capabilities can change with model and firmware.
