The practical signal
A user can see a camera and yet later not find a clip. The cause is often in a schedule or disk status, not directly in the camera recording.

NVR does not record: investigating the problem
Live image only proves that a camera is accessible; recording additionally requires a working channel, schedule, storage and writing function.
The control sequence
First, check whether there is actually no recording or whether it is being searched at the wrong time, channel, or event. View disk status and recording plan side by side.
What is smart to do
Restore the demonstrated missing connection and leave other settings untouched. Make channel names clearer if the search problem is operational rather than technical.
When it is completed
Create a test event and search it back in the timeline. Also check if a period without an event is considered part of the appointment's continuous recording.
Frequently asked questions
Why do I see live footage but not a recording?
Live connection and storage action are separate functions.
Can a full disk block a new recording?
This depends on the recorder settings and disk status; investigate this carefully.
