The guy running the project could use some critical thinking skills and answer his own question.
1.) Do people like being randomly recorded: No.
2.) Do people notice security cameras everywhere: Mostly no. Paranoid types like me might notice them more, and I'm sure we've got some of my fellow paranoid peeps around here, but most people just don't notice security cameras, and if they did, they couldn't do anything about it.
Thing is, security cameras in stores are for a purpose, and if I don't like that, I can leave.
CCTV in public is more annoying, but as someone who lives near rough neighbourhoods, and whose busmall is a cross between a white trash wedding and a brawl waiting to happen most times, I understand why they're needed. It means the police can effectively deal with problems. If I was really paranoid, I could worry about Future Totalitarian Dictatorships using Surveillance to control the populace, to spy on the people *GASP*, but I'm not crazy. Being worried about the security cameras is kinda ancilliary to the point there.
The footage isn't being archived forever, presumably, and the people watching it are skimming it looking for deliberate things.
So most people aren't so concerned about surveillance most likely because 1) They're not aware of it. 2) They understand there is a justification for using them, which actually helps them, and that the use of the footage is not illicit, or untowards. 3) They can't do that much about it.
This guy on the other hand, hanging around with a camera filming people, giving them both the person to talk to about it and no reason to justify their being there, and has given no indication to them of what he's doing it for. He's 3/3 for violating the reasons people are accepting of surveillance.
The proliferation of security cameras makes me uneasy, but they don't cause any nuisance, and I can get over them, so long as there are adequate rules about their usage. They're stupid, and kind of useless for the most part, but they're not really a threat.
Some wanker recording me (With Audio) in public does not have that benefit.
