The short answer
An event records that something was detected; video depends on a separate recording outcome. Match the event timestamp to a real, playable local file.
Work through the checks
Check both computer time and camera time, including time zone and synchronization settings. ONVIF authentication and event ordering can be affected by clock differences.
Match an event entry to the camera, timestamp and any linked local media. An event is metadata; its presence does not guarantee that a complete video clip was saved.
Check the actual recording volume, available space and write permission. Confirm the folder belongs to the intended disk rather than an unavailable USB drive or a redirected system folder.
If recording is available in the installed build, capture a short authorized test event. Confirm a new local file is created, grows as expected and can be reopened after recording stops.
What to verify
Reopen a completed test clip and seek to a known event time if the player permits seeking. Confirm moving images, duration and camera identity; a thumbnail or event row alone is insufficient.

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.
