I am the person in charge of the hotel. How to check if someone taps the camera in the room?

Buy something anti-spy, such as a bug. Or a wireless signal receiving surveyor. Go to places with security facilities. It's best to check the room thoroughly with the naked eye, and it's best to ask friends from the criminal police team to help. After all, pinhole cameras are hard to find. Supplement: Turn off the lights at night, and then carefully check whether there is light, usually red spots. It is said that you can turn off the power in the room, and then check whether there is anything that glows red in a hidden place, especially those furnishings facing the bed. Generally, if a camera wants to work, it must light up the indicator light. Remember to check the bathroom and shower room.
