FaceFirst

FaceFirst provides you with a powerful facial recognition platform designed to stop crime before it happens. By integrating with your existing surveillance cameras, the software identifies known offenders, such as shoplifters or barred individuals, the moment they enter your premises. You receive instant mobile or desktop alerts, allowing your security team to intervene proactively rather than reacting after a loss has occurred.

Beyond loss prevention, you can use the platform to enhance safety in hospitals, airports, and stadiums by identifying potential threats in real-time. The system also helps you recognize loyal customers to provide personalized service. It is built with a focus on privacy and compliance, ensuring you can manage identity data responsibly while protecting your physical assets and personnel.
