Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: obtaining first building event transaction data of a building using a first data source; recording a first blockchain block in a blockchain ledger, the first blockchain block having a timestamp and the first building event transaction data; obtaining second building event transaction data of the building using a second data source; recording a second blockchain block in the blockchain ledger, the second blockchain block having a timestamp, and the second building event transaction data; examining data of the first blockchain block and the second blockchain block; and providing one or more output in dependence on the examining.

A school communication system includes: a district server configured to manage at least one communication system located within a district location managed by the district server; a district network configured to communicatively couple the at least one communication system and the district server; and the at least one communication system. The at least one communication system comprises: a network switch configured to integrate communication equipment associated with the district location; and campus controller. The campus controller is configured to: receive an emergency drill configuration from the district server; receive a signal to begin an emergency drill; perform one or more actions in the emergency drill via the network switch; and report that the drill was initiated.

A method for real-time crowd management includes receiving LiDAR point cloud data from area of interest, forming a 3D static surface model of area of interest from LiDAR point cloud data, obtaining real-time CCTV camera images of area of interest, adding real-time CCTV camera images to 3D static surface model to generate real-time dynamic 3D model, identifying dynamic objects in the 3D model, generating a density map of an area of interest, adding density map to the 3D model, identifying which dynamic objects are people, replacing each person with animated character, displaying real-time dynamic 3D model, monitoring the 3D model in the area of interest for dangerous situations, simulating evacuation of area of interest by manipulating animated characters onto pathways leading away from area of interest, forming an evacuation strategy for crowd, and transmitting a notice of the dangerous situation and the evacuation strategy to an emergency authority.

A critical incident safety and security notification system for a building or multiple buildings, wherein upon the occurrence of a critical incident, the activation system signals a plurality of other safety and security systems to initiate, including the engagement of door barricades and informational and instructional notifications in the form of lighting, audio, text, and/or email being sent to the occupants of a building while simultaneously notifying first responders on a connected, web based platform that includes an integrated computer mapping system for critical incident location reporting.

The disclosed technology provides for generating simulation training models that can be used to prepare people (i.e., building occupants, first responders) to safely and calmly respond to emergencies, such as fires in high-rise buildings. Using the training models, people can better cope with decision-making during emergencies. The disclosed technology also uses signaling devices, wearables, and other devices and sensors distributed throughout a building to provide egress or stay-in-place guidance to people located in the building during an emergency. Audio and/or visual information can be outputted to people to guide them along a safe pathway that is selected to provide safe egress for the person, including anticipating and protecting the person from changing emergency conditions within the building and in response to how the person responded to the simulation training models.

A system and method for mapping indoor spaces including a mobile mapping device having a camera; a plan database configured to store 2-D floorplans; and a processor configured to integrate a selected floorplan from the plan database with object data received from the mobile mapping device to create a mountable evacuation sign of a venue. The processor is configured to recognise objects from an image from the camera and anchor the recognised object within a 2-D floorplan.

A device, system and method for crowd control is provided. An aural command is detected at a location using a microphone at the location. A computing device determines, based on video data received from one or more multimedia devices, whether one or more persons at the location are not following the aural command. The computing device modifies the aural command to generate a second version of the aural command based on one or more of the video data and multimedia data associated with the location. The computing device causes the second version of the aural command to be provided, to the one or more persons who are not following the aural command at the location, using one or more notification devices.

The exemplary embodiments disclose a system and method, a computer program product, and a computer system for generating a customized blueprint dynamically based on contextual data. The exemplary embodiments may include collecting contextual data within an environment and extracting one or more factors from the collected contextual data. The exemplary embodiments may additionally include generating an optimized path of egress by applying a model to the one or more factors and displaying the optimized path of egress on a device of a user.

The invention relates to a method for controlling access to hazard zones (202; 206) by a server (100), the server (100) comprising a processor (102) and a memory (106), the memory storing instructions in a form of an evacuation module (108), the instructions being executable by the processor, the method comprising electronically registering the presence of persons in the hazard zones (202; 206) by reader devices (208) associated with the hazard zones (202; 206), the registering being performed by reading ID tokens uniquely associated with the persons by the reader devices (208).
