If you're not doing anything wrong....

what are you worried about?
Nobody should complain about hidden cameras, right?

How about the Florida cop who took a TV station to court to stop a story where he appears on hidden camera cursing, screaming and chasing a person who asked for the forms to file a complaint against police?

Let's put publicly-accessible webcams in every police station and patrol car, and see how that goes over, before we start pointing them at or putting them in people's homes. After all, surely the police aren't doing anything wrong, are they?
