Prevent In-Custody Deaths

Go From Arrest to Rescue

Custody Protect is a tool for monitoring the health and safety of people in custody. We use biosensors that are placed on individuals at the time of arrest. These biosensors continuously monitor vitals and motion and use artificial intelligence to detect risks to health and safety. When we detect the first sign of a problem, we instantly notify the officers, supervisors, and control centers. By detecting danger early and alerting responders , we can save lives.
