Narsil is a system created by CallrTech to combat crime through technology. It uses a network of apps called the Octopus along with satellite and camera feeds processed through Narsil. The system aims to stop crimes in progress or catch perpetrators soon after through immediate information sharing. CallrTech plans to generate revenue through ads on the Hive information platform and selling early access to incident data. Their goal is to make it difficult to commit crimes and almost impossible to get away with them.
