Naofumi knew the soldiers had an orb. His POV on that episode zoomed in on the soldiers and centered on the orb itself. It was literally in the center of the screen when he felt something was wrong. If the orb wasn't there, it would just be soldiers lined up, giving him no reason to suspect anything. Therefore, it is most reasonable to believe the orb was the trigger and that he knew it was there.
There is no evidence showing that the orb can transmit video.
Just putting that out there because events that actually happened in the episodes might have gotten muddled up in the discussion.
EDIT:
Before anyone says I can only say these things in retrospect, I was literally screaming at the screen, saying "Capture those soldiers and get the orb!" many times while those soldiers started to flee in that scene. The letting enemies go and having it to bite your ass hard later is just that common (and stupid) a trope. Naofumi, an otaku who likes to read, should know that too.
