Wanting there to be mass surveillance is anti-libertarian?

I am from Mexico and as you know, there is too much crime and violence, there are robberies, assaults, kidnappings, extortions, murders and rapes. I think a solution to this is to put a camera in every corner of the country so that people are always watched and criminals think twice before committing a crime. Obviously I believe in economic freedom and individual freedom (abortion, homosexuality, drugs, etc) but wanting my country to be filled with cameras makes me anti-libertarian?
