When the socket in the hotel is turned off, there is a pink light spot with your mobile phone. Is it a pinhole camera?

Maybe there are cameras. When entering the room, turn off the lights, draw the curtains, keep it absolutely dark, turn on the camera of the mobile phone, and carefully and slowly scan every corner of the room. Once a bright spot appears on the dark mobile phone screen, it is likely to be a miniature camera.

Or you can use other methods to check, and use a flashlight to check all the exposed holes in the room, such as vents and power sockets. If there is a hidden pinhole camera, you can find the reflector by flashlight lighting.

There is also an anti-sneak shot APP, also called a camera detector. The main principle is to detect whether there is a camera connected to the same WiFi.
