I stayed in an apartment hotel, and there was a camera-like object in the room. I want to know what it is.

Friend, this is an emergency light, that is, when there is an accident in the hotel, the main line of the power cord will be cut off, which means that the hotel has no electricity and can only use the emergency light to facilitate the rescuers of the rescue team to perform the rescue task. Understand that meaning! Of course, the emergency lights in some hotels are just a decoration, and they are not used at all. Some hotel emergency lights are invisible cameras installed by individuals, you know! In short, if you don't like a hotel room with emergency lights, you can change to another room. Is that clear now? Tell me what you don't understand, and I will help you. I hope to adopt my answer!
