How to find a camera in the hotel?

Method 1: Flashlight inspection method

Use a flashlight or mobile phone flashlight to illuminate the exposed holes of the hotel, such as vents, radiators, televisions, etc. If there is reflection, there may be a pinhole camera. This method is used because most pinhole camera lenses have coating design, and coating can be quickly identified by lens reflection because of its special color.

Method 2: Mobile phone screening method

This method can be used to check pinhole cameras using functional infrared fill light. After entering the room, make the indoor environment as dark as possible, and make the room as dark as possible, such as closing the curtains and turning off the lights. Then turn on the camera of the mobile phone and start scanning every place in the room where there may be pinhole cameras. If there is a light spot on the screen of the mobile phone, it is very likely that there is a pinhole camera in this place.
