Detection method of hotel camera

Turn on the camera function and flashlight of the mobile phone.

Turn off the lights in the room and close the curtains. Leave the room in a dark state without any light. The darker the color, the better the inspection status. Then turn on the camera function of the mobile phone, walk around the room and check the dead angle and ceiling of the room. Television, air conditioning and other places where pinhole cameras may be installed. If there is a pinhole camera, you will see a red dot on your mobile phone. The red dot is a camera.

Shine a flashlight at each pinhole that looks like a hidden camera, and then observe the reflected light. The best way is to shine a flashlight on the front camera of a laptop or mobile phone and shake it back and forth. If you see this little color reflection, shake the flashlight and you will start. This is usually the lens reflection of the camera.
