Our project Safe neighbourhood is a security system designed for our living neighbourhoods. We describe unordinary approach to home security where we do not focus on a single residential building but rather on multiple geographically linked homes that use common security system. Ideas for our project came from neighbourhood watch organizations and modern technology concepts like the internet of things, connected classical security systems and advanced sensors. The project Safe neighbourhood connects people to a common effort against crime. Authorized neighbours get limited control over our security system, which is accessible through mobile and web application. Our solution allows users to provide security in their own neighbourhoods in an effective and safe way.
