In the wake of school shootings, bullying, natural disasters, and other threats, districts are increasingly turning toward technological systems to enhance the safety of their campuses. These technological systems, know as Cyber-Physical Security Systems (CPSS), bridge the physical and the digital environments. CPSS equipment can range from entryway cameras, automatic locks, and intercoms to facial recognition software and biometric readers. These systems can be integrated to form an advanced security platform capable of automatic threat detection and facility lock-down; remote video observation through web-enabled camera systems; and enhanced communication with district personnel, students, community, and first responders. The impact of these technologies on physical facilities, network infrastructure, and district procedures and policies and must be considered as part of a larger, holistic school security approach.
