There's a pretty big difference in stated intent. It doesn't seem unreasonable for a person to be OK with being filmed for the purpose of e.g. theft prevention, but not for some kind of modern art project / protest statement. Edit: to be clear, the opposite also doesn't seem unreasonable. If someone told me they were OK with being filmed for a modern art project, but not for theft prevention, I wouldn't find that particularly odd either.
