A control system for optimising emergency multi-storey building stairwell evacuation, the system includes an occupant tracking subsystem configured to monitor the locations of building occupants within a building as the occupants move between floors of the building so as to be able to continuously calculate the number of occupants on each floor of the building at any time, such that, during an emergency. The control system is configured and able to, using an access door controller subsystem: control the closing of a plurality of access doors of a stairwell; and control the successive opening of certain access doors of certain floors of the stairwell in accordance with an evacuation plan. Wherein the evacuation plan is dynamically configured in accordance with the calculated number of occupants on each floor of the building.

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 method for monitoring devices based at least in part on detected conditions includes accumulating, by one or more sensory nodes, sensed information in an area that includes a controllable device. The method also includes analyzing the sensed information to identify historical information regarding the area that includes the controllable device. The method also includes sensing a condition within the area by the one or more sensory nodes. The method also includes determining, based at least in part on the sensed condition and at least in part on the historical information, that the sensed condition relates to the controllable device. The method further includes generating, responsive to said determining, an alert regarding the controllable device.

An emergency guidance and advisement system is provided to automatically determine a floor map of a building and using the floor map for advising how to exit the building during an emergency, such as a fire. The system can automatically create an escape plan, based on pre-disaster and in-disaster motion detection of users within the home, and provide dynamic advisement to guide users out of the home during an emergency.

A building event response processing method, a building event response processing system and a storage medium. The building event response processing method includes acquiring a current event occurring in a building area; and performing a rating response processing for the event according to a decision tree model, wherein the decision tree model is built by setting respective pre-set rating response processing for each event based on at least feature attributes of the events, and the rating response processing comprises at least a first-level response processing for the event.

A gunshot detection/security system for detecting dangerous events in a school or other building includes one or several pods placed throughout the building premises. Each pod includes a camera, a thermal camera, and an acoustic sensor for detecting video, images, heat signatures, and sound within a detection area for the respective pod. The sensor data is then analyzed to identify a dangerous event in the building, and provide alerts regarding the dangerous event via the pods or client computing devices of students/occupants in the building, administrators, parents, and emergency responders. A server computing device generates digital maps of the interior and exterior of the building having location information regarding the occupants of the building and a danger zone indicating the epicenter for the dangerous event.

A device, system and method for evacuation task management is provided. A computing device: receives initial sensor data from sensors of a building; generates respective evacuation instructions for evacuating persons and objects from the building for each of responders, the respective evacuation instructions generated from rules for evacuating the building and the initial sensor data, each person or object associated with at least one of the sensors; transmits the respective evacuation instructions to a respective communication device of the responders; monitors updated sensor data from the sensors during evacuation of the building and location information associated with each of the responders, to track compliance with the respective evacuation instructions; and transmits updated respective evacuation instructions to the respective communication device of one or more of the responders, the updated respective evacuation instructions based on monitored updated sensor data and monitored location information received after transmitting the respective evacuation instructions.
