In Norway where surveillance cameras are still rare and strictly regulated, I can go anywhere and feel safe. That includes a park where drug addicts used to get and sell drugs. For few years I often passed it during the day and night. At worst somebody would ask if I wanted some substance. So I suspect violence is affected much more by culture/policy than cameras. Surely cameras may help, but for them to work one already needs a functional society. For example, cameras do not work when one can bribe police/courts to remove/ignore video evidence, like it happens in Russia.
