I did some research on how to declare a webcam in public restricted space (airfield) with no surveillance goal and no image recording.
But it seems a camera has to be for surveillance, no gov site allows you to declare a camera that just shows a big green grass runway, trees, clouds and a windsock if you can't identify people.
I'm sad for cameras if their only purpose in life is surveillance. Where is the poetry, just showing the beauty of the world?
