We’re on a mission to make the world a safer place.

Calipsa was born in London in 2016, founded by a team from Cambridge, UCL and Imperial Universities. We saw the burden that false alarms place on the security industry and believed we could make a real difference to crime prevention through a unique new approach.

We build technology that transforms the way we detect and prevent crime, and empowers security professionals worldwide to make better decisions, in real-time. Calipsa uses cloud-based machine learning technology to reduce the number of CCTV alarms by over 85% and transform false alarm management in video monitoring.

As the global leader in false alarm reduction, we’re committed to developing technology to support your people, not replace them. We’re passionate about creating a future where humans and technology work together to eliminate crime.
