Dutch people are non-confrontational. You really went out of your way to elicit a reaction. You walked towards them, got on their face, stood there and didn't acknowledge them or responded even when they spoke to you and greeted you.
If you did the same, even without a camera, you'd get the same reaction. The camera has nothing to do with it.
Also, even the name or "project" is dumb af, cause this is nothing like a CCTV camera. CCTVs are legal on public spots, because they're static and not following you around, persisting even if you try to walk in a different direction to avoid them. What you're doing is harassment and it's illegal even in countries with very lax photography laws. If you wanted to simulate a CCTV you should have picked a spot, stayed there, and filmed passerbys.
On a sidenote, I shoot people in Amsterdam and haven't had a single ""confrontation"" yet, apart from the occasional person doing goofy faces/poses and laughing.
