What SafetyRadar does? What are the technologies behind what is called “PPE monitoring, performed by artificial intelligence”?

When you sign in to SafetyRadar, you see a user-friendly interface and a bunch of tasks you can perform in it. But what lies beneath? The main thing about SafetyRadar is it is a cloud software solution, based on artificial intelligence and machine learning. 
Computer vision and object detection algorithms inside allow it to automatically identify the absence of protective clothing and equipment on people. This makes SafetyRadar an automated assistant, which constantly accurately monitors PPE compliance in working environments. Moreover, it is trained not to observe only, but also to notify users about violations. This means, when a person in the sight of a camera doesn’t wear obligatory PPE, SafetyRadar classifies this as a violation. And sends a notification to the user.
