These days school security systems consist of a little bit more than just a truant officer of the 1970's and before. Thanks to always evolving technology and reduced prices, a digital video security camera system usually plays a big part in school security systems as well as maintaining order within the classroom.
In the not too distant past, school surveillance and security systems were unheard of. The closest thing to school surveillance was probably an intercom speaker in each classroom and the security system might have been a truant officer, if the school had one. Today’s complex social behaviors and societal problems can encroach upon the school atmosphere limiting not only the safety of the students, but the actual ability to learn.
