You seem to have misunderstood an is/ought distinction. You may hold the (fairly extreme, as far as copyright goes) position that surveillance footage should be subject to copyright, but it's well established that it's not. Who owns the camera is irrelevant. At least in the US; I'm not aware of any jurisdictions that hold otherwise. This is why Wikipedia articles on world events in the past few decades are full of stills from surveillance cameras: it's one of the few sources of imagery of an event that are unambiguously legal to include, because unlike a photo or intentionally made video of something specific, it's not a creative work. It's also pretty firmly established that human authorship is required for something to be subject to copyright, and having an idea that lead to some particular expression is itself not sufficient; see, e.g.: https://en.wikipedia.org/wiki/Monkey_selfie_copyright_disput...
(Not a lawyer, just a Wikipedia editor.)
I appreciate your informed take. I follow the reasoning but I am amazed it works this way. I found some articles that supported what you said, and also said there's a follow-on industry that figured out how to alter and edit videos just enough for a revised video to have creative contribution and make it copyrightable.

This is a great case to study, but no determination of copyright was made. The only actual lawsuit was filed by PETA arguing that the monkey should have copyright, which led to a settlement with the human photographer and nothing else because obviously that's not possible.
For various reasons (mostly $$$) the guy never actually got a judgement. I think the chances are good that he could have prevailed in court; there is significant creative input to setting up cameras and triggers in a way to convince a wild monkey to take a selfie. It's not like he just left his camera sitting somewhere on accident and came back to find a photo in it.
I'm also not a lawyer, but I did do a lot of work in copyright for a company you've heard about.
