How to test whether there is a camera in the room with a mobile phone

How to test whether there is a camera in the room with a mobile phone. Everyone will choose to stay in a hotel when they go out for fun. When we go out, we must protect ourselves, not only to protect the safety of our lives and property, but also to protect our personal privacy. Let’s take a look at how to test whether there is a camera in the room with your mobile phone. How to test whether there is a camera in the room with a mobile phone 1

The method to test whether there is a camera in the room is as follows:

1. Scan with the mobile phone

Enter the room, first turn off the lights and Draw the curtains, keep in an absolutely dark environment, turn on the camera of your mobile phone, and scan every corner of the room carefully and slowly. Once a bright spot appears on the dark mobile phone screen, it is likely to be a micro-camera.

2. Flashlight inspection

Use a flashlight to check all exposed places in the room, such as vents, power sockets, etc. If there is a hidden pinhole-camera, reflective objects can be found by shining a flashlight on it.

3. Check ornaments and clocks

Screws or details on some stuffed animal eyes and clocks often obscure the camera. Since both stuffed animals and clocks are easy to move, consider moving them out of the vicinity if you suspect there is a camera inside.

4. Make a DIY camera detector

A professional camera detector will be very expensive, but we can use a small paper tube and a flashlight, or the flash of a mobile phone to combine it. Place it at eye level and turn on the flashlight. Scan the room and make sure the flashlight flashes back and forth at a high frequency. Then you can spot the camera.

5. Anti-candid APP

This APP is also called a camera detector. The main principle is to detect whether there is a camera connected to the same WiFi. This kind of APP also has some shortcomings, that is, not all candid shooting devices are connected to WiFi. Some cameras store the candid shooting content in the memory card for temporary storage and do not transmit it to the terminal in real time. At this time, the anti-candid shooting software cannot Detect it. How to test whether there is a camera in the room with a mobile phone 2

If you are using a vivo mobile phone, the iButler camera detection function can detect suspicious cameras in hotels, B&Bs and other scenarios, giving you more peace of mind in privacy protection. You can stay at ease when traveling on business;

How to enable it: You can enter iButler--Utility--Privacy Protection--Camera Detection, click Start Detection, the webcam under the current network will be detected first, and the detection is completed. The words Manual Detection will be displayed at the bottom of the page, and you can click Manual Detection.

Warm reminder: Before indoor testing, you can close the curtains, turn off the indoor lights, and ensure that it is in a dark light environment.

In fact, it will be very simple to solve this problem as long as you know one truth. Cameras generally have infrared rays inside. Generally, if we are in a particularly dark situation, the camera will emit a trace of red light, some of which are not obvious. , but you can see it if you look carefully.

When staying in a hotel, many people are afraid that the hotel will secretly install a camera for you. A common method used by people is to turn off the lights and then carefully look at every corner to see if there are any red dots. Light. In fact, many people think that this method of looking at red dots is more troublesome and very taxing on the eyes. You have to look very carefully to see it. Some people use their mobile phones to take pictures after turning off the lights, and then keep taking pictures of every place. In this case, the red dot in the mobile phone camera will be particularly obvious.

Another method is that you can use your mobile phone to turn on the flashlight after turning off the lights, and then look at the wall to see if there is a reflective place, which is different from other points. Generally, cameras If you shine it like this, it will reflect light and it will be obvious.

In fact, there are usually no cameras in your room. No matter whether the camera is big or small, it is the same thing. There are cameras in our high school classrooms. The camera, even if you turn on the light and look at her sometimes during the day, there will be a red dot flashing inside it. When our school first installed this, we observed it every day, because at that time we thought it was very advanced and magical. At that time, it was easy to see the red dot inside its camera. One way to detect whether there is a camera is to look at the red dot, or shine a flashlight on the mirror. He will reflect the light.

Check whether there is a camera in the room outside, a mobile phone can solve the problem. The first thing we have to do is to turn off the lights and draw the curtains to make the room in a dark environment; then turn on the camera mode of the mobile phone and walk around the room, focusing on the various blind spots in the room and where the camera may be hidden. Places, such as ceiling lights, TVs, routers, switches, air conditioners, etc. During the inspection, if a red dot appears on the phone screen, it means there may be a camera hidden there. Turn on the lights to verify, if it is really a camera, then we need to call the police. How to test whether there is a camera in the room with a mobile phone 3

1. Wireless camera detection

Turn on the radio in the mobile phone, try not to make any sound, and then walk around the room with the mobile phone, especially It is against the wall or somewhere where you think something may be hidden. If you find that the sound quality of the radio has changed, it means there is a camera at that location, because the audio confusion causes the sound received by the radio to change!

　2. Infrared camera detection

This is a commonly used method for detecting cameras. Turn off all the lights in the room, draw the curtains, make the room in a very dim environment, and then turn on the mobile phone. Use a camera to take pictures of the room. If you find red dots appearing in your lens, these are infrared pinholes - cameras!

As a professional anti-voyeur detection company, we do not deny that the mobile phone will be detected under certain conditions. It is effective, but we more often choose optical detectors for troubleshooting. However, many e-commerce platforms often call them "infrared detectors" and "laser detectors" in order to attract attention. Such names are pure nonsense. The optical detector, in a relatively dark environment,

emits red light or green light to the detected location in the environment. When the light hits the pinhole-camera lens, it passes through the filter of the optical detector. The reflective spots reflected back from the lens will be clearly visible in the observation hole of the mirror. Why is it red or green light? Because during detection, these two types of light are most easily captured by the human eye through the professional filter glass built into the detector.

3. Use a professional video scanner

Use a video scanner to simulate the pinhole of the signal that transmits data - the camera and demodulate to restore the camera's shot. However, non-analog cameras or cameras whose signals transmit data with encrypted signals cannot be captured.

4. Use a flashlight to check

Use a flashlight to check all exposed places in the room, such as vents and power sockets. If a pinhole-camera is hidden, reflective objects can be found by shining a flashlight on it.

5. Anti-candid camera APP

This APP also has some shortcomings, that is, not all candid camera devices are connected to WiFi, and some cameras store the candid camera content in the memory card. It is temporarily stored and not transmitted to the terminal in real time. At this time, the anti-candid photography software cannot detect it.

It should be noted that nowadays there is no simple anti-candid photography method with a 100% success rate. Candid photography and anti-candid photography are two parties that are constantly competing. If more methods are used, the success rate can be improved.
