The key element here that everyone seems to be confused about, is secret vs non-secret.
If you have an obvious security camera, or an obvious camera that normally would record audio, and you’re in public waving it around and it records audio? You are not secretly recording audio.
Same if someone is standing next to a obvious and clearly visible security camera which normally could also record audio, also, not secretly recording audio.
A hidden mic in your jacket, or like in that case, hiding the camera under a jacket? That is hidden recording.
The general rule of thumb is - if everyone can clearly see what you’re doing, it’s not secret.
