How to see if the hotel has a pinhole camera?

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.

Sneaking often hides the location of the camera.

Pinhole cameras can be forged into the appearance of some daily necessities, such as lighters, tissue boxes, shower gel, sockets, smoke detectors and so on. The closer you are to the power supply, the more you need to check.

Bed and bathroom are two points that are easy to be photographed by criminals in the hotel. The possible hidden positions of pinhole cameras in hotel rooms include: small objects beside the bed, ornaments facing the bed, sockets on the wall, paintings hanging on the wall (a hole may be dug on the black edge, which is not easy to find), and small objects in the bathroom.
