If you need to carry a clip away from a Reolink NVR, verify USB export with a short nonprivate recording before buying a larger drive.
Set up a controlled test
Check whether your recorder uses the interface covered by Reolink’s instructions. Find a known event and write down the channel, date and start time. Use a spare compatible USB drive that does not hold your only copy of anything. Do not format or erase an existing drive as a diagnostic shortcut.
Read the result
Export a narrow window around the event. Open the resulting file on the device where it actually needs to play and check that the important seconds are present. A file appearing on the USB drive is not the same as successful playback.
Worked example
If a ten-minute window is cumbersome but a one-minute export includes everything you need, shorten the selected range before spending on storage. This tests removable export, not expansion of the NVR’s recording capacity.
