How to check whether the room is equipped with a camera when staying in a hotel outside?

If you want to know if there is a camera in the hotel room, you can put the curtains in after opening the door, then turn off the lights and turn on the camera of your mobile phone. Then scan the room with your mobile phone. If the phone has a bright spot, it means there is a micro camera. The hidden camera is small and hard to see with naked eyes, but the mobile phone is sensitive to the light source and can capture this faint flash.

Most people live in hotels casually, so they don't worry about whether they have cameras, but some hotels are particularly high-end, and some perverts will install cameras just to spy on other people's lives. Others will put cameras in the bathroom. If the picture appears, men may not watch it. If the woman takes a shower, she may record a video and sell it. So it is very important to master some methods to check the camera. The method introduced by Bian Xiao above is very practical. If it is daytime outside the window, you can check it at night, so the effect will be more obvious.

In addition to the above methods, you can also look at the places where pinhole cameras are easy to grow, such as hanging feet on the ceiling, chandeliers, and behind the corners of patch panels. Some people will remove the patch panel and put the camera in the hole. If the charger is plugged in, the camera can't shoot anything, but the charger can't be plugged in all the time, and the camera can also take some pictures. You can also buy a strong flashlight online. If you find the camera, the flashlight will reflect light. Mobile phones also have flashlights, but the light is not very strong. A strong flashlight can focus light and find some hidden cameras.

If the economic budget is relatively high, you can buy an infrared detector, and you can find all the cameras with one photo. Whether it is infrared or needle eye, it is invisible under the infrared detector as long as it is powered.
