The short answer
ONVIF specifies interoperable services and profiles, not a promise that every optional feature exists. Check device version, advertised capabilities and permissions for the operation you need.
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 ONVIF-reported media profiles where available, and record the selected profile token. Profiles can differ in resolution, codec, audio and PTZ associations.
Verify that the device reports the required ONVIF PTZ capability and that the local account has control permission. Begin with a small supervised movement and confirm the stop response.
What to verify
Write down the exact outcome you need: live observation, a saved event, camera movement or long-term retention. Check each outcome separately instead of treating a visible stream as proof of all functions.
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.
