No, private rooms do not belong to the category of public environment. Private rooms in beauty salons are relatively private. For example, cupping needs to be undressed. Generally, there is no surveillance camera installed in the private room, so there is no camera in the cupping room of the beauty salon. When installing a camera in a beauty salon, its location must be clearly marked or placed in an obvious position to ensure that customers know it. The installation location is limited to public places, excluding private places such as dressing rooms and toilets. Beauty salons have the obligation to properly keep and correctly use relevant audio and video recordings, and no individual may disclose the contents of the camera without his permission.
