Why does the presence of a camera change the rules for distance? The article says that CAA is only making safety rules, not anything relating to privacy.
As such, you don't need to stipulate that there is a line of sight as you fly using the camera / video feed.
Edit: whoops. i read that 150m part _completely_ wrong, cheers vp
I suspect their 150m surveillance rule is part privacy, and part a belief that if you're trying to film something/somebody with a camera you pose a higher risk than if you're just flying past them.
