Nowadays, everyone is paying more and more attention to their privacy and paying great attention to protection.
But anyway, there are some things that are really hard to guard against, especially in different places such as hotels, B&Bs, etc.
Speaking of which, there should be many friends who have thought of today's title.
In this case, how do we determine if there are cameras installed in these places? If someone ** the details of our lives, it will be a serious violation of our privacy.
An important rule of thumb when looking for a camera is to pay attention to the bathroom and the angle from which the bed can be captured, as criminals often want to get footage of these places.
Among them, focus on these places: smoke alarms, electrical outlets, night lights, small holes in the wall, decorative paintings or other decorative objects, bathroom mirrors, etc.
Pay special attention to the socket and the night light, two locations that are particularly easy to hide the camera. Bathroom mirrors are also a potential problem area.
If you notice that an ornament (such as a mural or ornament) is of a strange height or position, you should pay special attention. For example, if the mural is hanging in a corner, or the ornament is in a very abrupt position, be sure to check it.
Having said that, today I will teach you how to use your mobile phone to detect whether there is a camera in the room to ensure your own safety.
The first trick: mobile phone flash check!
Dim the lights in the room to make it dim, turn on the flash of your phone, and aim it at all corners of the room, walls, ceilings, furniture, etc.
At this time, it is necessary to carefully observe whether there is abnormal reflection or flickering on the screen of the mobile phone. If there is, it is most likely the location of the camera.
How it works: The camera's lens reflects the light from the flash, creating a noticeable bright spot or flickering on the phone's screen, making it easier for us to find the camera's location.
The second trick: mobile phone magnetic detector check!
This method requires the mobile phone to have a magnetic detector function, or the corresponding software can also be used.
First of all, turn on the magnetic detector function of the phone or the corresponding software, and place the phone close to the places in the room where the camera may be hidden, such as sockets, switches, lamps, TVs, air conditioners, etc.
Then, carefully observe the magnetic force indication on your phone's screen for unusual changes or fluctuations. If there is, it is most likely the location of the camera.
Principle: The circuit of the camera will generate a magnetic field, which will affect the magnetic detector of the mobile phone, so as to determine whether there is a camera in the room through the magnetic indication of the mobile phone.
The third trick: software-assisted check!
You use mobile phone software such as 360 Mobile Guard, King of Glory and other auxiliary detection, by opening the settings and clicking on the network diagnosis to start the detection, to see if there are other network signals nearby.
Principle: The camera network is usually connected to another network signal to transmit data, etc., so that you can judge whether there is a security risk by finding unknown network signals.
Of course, in addition to the method of mobile phones, if you are unsure, you can use items such as paper towels, bath towels, tape, and post-it notes to cover suspicious locations.
In the case that there may be a camera hidden inside the bath mirror, be aware of the double-sided mirror, which has a mirror on the front and glass on the back. It was originally used for floor-to-ceiling windows, but it was used by criminals.
The identification method is very simple, when touching the mirror with your finger, there is no obvious gap in the double-sided mirror, while there will be obvious gap in the fingertip of the ordinary mirror.
Alternatively, you can turn on the camera and use the forced flash to shoot close to the glass. If you have a double-sided mirror, you can take a picture of what is behind the mirror.
Okay, that's all for today's content, I hope it can help you.
