Just something I noticed reading Harry Potter and the goblet of Fire

Did no one realize that the whole plot behind the goblet of fire,  and the whole mystery of who entered Harry into the Triwizard competition could have been solved if there were simply security cameras in Hogwarts? Haha, that is just a thought. The whole mystery could have been avoided that way!

Who is that hiding under the invisibility cloak? Harry... Is that you? No?
