camera check option

Hello, I am taking a real-time Zoom lecture online in Korea. I would like to ask you because I have a question about the zoom function while listening to the lecture. If a student turns off the camera during the real-time lecture, can you tell me how many minutes he or she has been turning off the camera? And, I would like to ask if it is possible to set a separate rule or option for a student who turns off the camera for a specific time (for example, 10 minutes).
