First and foremost, our mission is to protect human health and safety. Accordingly, we developed Custody Protect to give police officers a new tool to safeguard human life. Custody Protect is an artificial intelligence platform for monitoring the health and safety of those in custody. Moreover, Custody Protect detects health crises in detained individuals and alerts officers before it is too late, allowing police officers to go from arrest to rescue in the blink of an eye. The result is an improved ability to save lives that could not be achieved with visual observation alone.
