There is a hidden camera in the hotel bathroom hook. How to check the camera when staying in a hotel?

Today, let's talk about how to check the camera when leaving the hotel.

If you want to check the camera, you must start with the working principle of the camera. For example, any camera needs to step into visible light before imaging, so the first thing you can start to check is the lens. All the lenses can reflect light well, and the reflected light is very distinctive.

The first is that the original environment is white light, which will become colorful after reflection, because the refractive index of glass will be different for different colors of light. The second is that the lens is a convex lens, and the reflection point will be much smaller than the incident light, which can also be used as an important means to find the camera. The search method is very simple. You can hold a flashlight to illuminate every hole that looks like a hidden camera, and then observe the reflected light. If you can't, you can hold a flashlight and shake it back and forth at the front camera of your laptop or mobile phone, and then observe this small color reflection.

Or you can find a power supply, because the invisible camera needs to work for a long time, so it usually doesn't need a battery to power the camera. Therefore, the power supply is the most essential part of the camera, which also limits the camera's general need to pull the power cord in a hidden place or install it directly in electrical appliances.

Cameras are often hidden in the following places, such as smoke detectors in cartons, office supplies, plants in rooms, etc. And they are still hidden in some less obvious items, such as air filtration equipment, desk lamp buttons, screwdriver, wallet DVD and so on.

And you should also look for a mirror in this area, because there may be a camera hidden behind the mirror. If you don't find it, don't let your guard down. At this time, you should be careful about the area that can provide the best view, and be more careful about some translucent plastic. There's probably a camera hidden behind it.

If you usually put your mobile phone next to the computer speaker, if a phone calls in, the speaker may hum. You can use this method to make a phone call with your mobile phone and then check the suspicious area. If the cell phone also beeps, it may have a camera.

Or you can use the flash detection method to detect hidden cameras. In a room, you can turn off the lights first, and then turn on your mobile phone to take pictures instead of turning on the flash. Walking around the room with a mobile phone, if you find a red dot, it means there is a camera. This method mainly depends on whether the camera has an infrared compensator.
