Correção de texto: Security Cameras

Tenho prova na segunda. Só importa a gramática, se eu não cometi erros. Obrigado o/

Basically, I think that security cameras are nice. They help police solve crimes, they reduce property and pre-meditated crime and so on.
However, they give a false sense of security in public places. If a country dosen’t have a sufficiently safety standard, there is nothing that security cameras can do.
Futhermore, that’s a seriously point, security cameras can be used to attack the privacy. George Orwell showed it in his book – the famous 1984.
In conclusion, I agree with the security cameras if they aren’t used to limit our liberty.
