Disclosed is a back-end system for emergency response, and a corresponding front-end system. The back-end system handles network communication to and/or from multiple information sources for gathering emergency response information from the information sources, including at least video data related to an emergency and/or security situation and additional emergency response information. The back-end system extracts subsets of information from the emergency response information at least partly based on input originating from one or more users and/or operators. The back-end system is configured to perform processing of the emergency response information to enable formation of a common overview of the emergency and/or security situation valid for different users/operators, while also enabling the emergency response information and/or extracted subsets thereof to be processed, compiled and/or filtered, and/or presented to a specific user and/or operator in a way that is customized for the specific user and/or operator of the emergency response system.
