Abstract: A method for improving safety and property protection in schools comprising fixed and mobile safety and security devices, networked together. A software App provides real-time communication among various devices. The network integrates disparate security devices into a unified system to expand coordination and communication among public safety personnel. The system automatically triggers alarms, cell phone notifications, and warnings, as well as defensive measures, when its sensors or safety devices detect or report threats to public safety and property. Each device in the system is pre-programmed to respond independently while simultaneously sharing its findings with all other devices and security personnel in the network. Deployment of these disparate devices gives security personnel heightened awareness, real-time status of secured and unsecured building entrances, around-the-clock visualization, and faster response times in both indoor and outdoor emergencies.
