The larger the school campus, the more complex is its security requirements and again, video surveillance and access control are the two core integrated systems.

Video surveillance is needed to protect the facilities and the students. Access control systems, especially in student housing, are needed to control who gains admittance into the building. Often this involves a combination of a card access system and video. Schools also have video cameras in hallways and rely on higher-megapixel cameras to better identify people.

Mass notification systems are a more important consideration, as evidenced by the Virginia Tech and Northern Illinois University shootings in 2007. Most colleges and universities are implementing a text messaging mass notification system.
