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%. 

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.
