I cannot understand people's psychology when it comes to cameras

I have written about this exact subject before, so I'm just repeating the same ideas, but feel like I need to write about it once again because I just keep seeing the same thing again and again.

There seems to be this strange psychological phenomenon, especially in the United States but also in many other parts of the world, where people are bothered by cameras filming them in public... but only if the camera is being held by a person.

They might literally walk in full view of 20 fully and clearly visible conspicuous cameras attached to walls, ceilings and poles, and they pay no attention to it and are completely ok with it (even though in many cases they have absolutely no idea who those cameras belong to, or where that footage is going.)

Moreover, they might walk across the front of cars with visible dash cameras inside them, and even modern "smart" cars with a dozen small cameras all around them... and not be bothered at all (even though, once again, they have no idea who those cameras belong to, or where that footage is going.)

But if they are filmed by someone holding a camera in his hands, they immediately become concerned, and a lot of people even go confront the guy, usually making one of a half-dozen standard statements, which are variants of "what are you filming for?", "you do not have permission to film me", "you can't film people without their consent", and sometimes even an outright "it's illegal to film people without their consent."

Quite notably, they never do that with cameras attached to walls and ceilings even when they do know who those cameras belong to. For example, you never, ever see these people seeing a camera on the ceiling of a grocery store and walking to a store clerk and telling him "you don't have my permission to film me", or "it's illegal to film people without their consent." Never.

Ironically, the guy holding the camera could literally attach some "security camera" looking camera three meters up a utility pole and then stand below that camera holding another camera in his hands, and people would come to complain to him about his handheld camera, but pay no attention to the camera that's right above him attached to the pole. Seriously.

And quite curiously, they don't become concerned about cameras attached to the scenery, or even dash cameras inside cars, even when directly pointed out to them: "There's a camera there on that wall, pointing directly at us, and another one on that other wall, also pointing at us. There's also a dash cam inside that car, also pointing at us." Doesn't matter, they are not bothered by those cameras, only the one being held in the hands of the guy who is standing there. They dismiss those other cameras even when explicitly pointed out to them. Or they make some vague excuses about those other cameras (often "they are security cameras", as if that somehow made some kind of relevant difference), and just ignore them.

Why?

I literally have no idea!

I would perhaps understand that if the guy mentions the other cameras attached to walls and poles, the concerned passerby would then perhaps become visibly bothered and say something like "well, actually, now that you mention it, I had never thought of that. I do indeed not know who owns those cameras or where that footage is going. It is a bit bothersome of an idea now that I think about it."

But no. That's never what they say. They either completely ignore those cameras being pointed out, or they dismiss them with some vague quick excuse. Only cameras being held by people are concerning to them, not cameras attached to the scenery (including dash cameras inside private cars).

Again: Why? What's the psychological phenomenon behind this? I have no  idea.

It's also funny when some of them claim that it's "illegal" to film people in public without their permission. They are never able to tell why cameras attached to scenery or cars don't need that permission, ie. why that permission is only required for people holding cameras. If explicitly asked this question, they usually just ignore it (quite obviously because they don't actually know the answer and don't want to think about it too much.)

Also, quite hypocritically, the exact same people who claim it's "illegal" to film people without permission will then quite often take out their own cellphones and start filming the guy without asking his permission. Something that, according to them, is supposedly illegal.

(When this hypocrisy is pointed out to them, they always, always, always, 100%, give the exact same response: "You are filming me!" As if that legally justifies filming back. Not that they would be able to site such a strange law, of course. In fact, I find also this stock answer, which every single one of them always gives, to be psychologically strange and interesting. Where is this psychology coming from? Why is there zero variation in such responses, other than perhaps extremely small variations in the words used?)
