This machine learning system which can detect “criminal behavior” was developed by researchers at the University of Cambridge, the National Institute of Technology of India and the Indian Institute of Science and Technology. It is a system with artificial intelligence technology that uses a hovering quadcopter and uses the camera to detect the body movements of everyone.

Then, when the system recognizes the aggressive behavior, such as punching, kicking, assassination, shooting, strangle the neck, etc., it will issue an alert with an accuracy rate of 85%. But it does not currently recognize faces, it just monitors possible violent behaviors between people.
