What about the cameras in the hotel?

In my opinion, this problem cannot be completely avoided by tourists themselves.

Because I have also read relevant reports, even some hotels that look very formal will install cameras with night market function in air-conditioning ports on the wall, behind mirrors, gaps in desks and other places that are quite hidden and facing the bed, and also have eavesdropping function. It is said that the camera can also change the angle and then sell these stolen pictures of personal daily life.

Therefore, individuals can only stay in chain hotels, try to wear clothes and rest in their rooms, and try not to make phone calls that expose personal property or privacy, that's all.
