What should I do if I find a camera while staying in a hotel?

To report, you must first choose the top management of the hotel. Generally, hotels have supervision service telephone numbers, which can be dialed directly and will be followed up soon. If the hotel fails to handle it properly, you can call the police directly at 1 10. For on-site treatment, evidence can be kept and the discovered equipment can be photographed. After retaining the evidence, you can report it online. It is generally best to submit evidence within 3 days after the event!
