As technology advances, users and internet users are becoming more and more concerned about their privacy. Not only because they fear being spied on by electronic devices such as cell phones or computers, but also because of other types of devices such as hidden cameras.
It is common to take several steps to protect personal information and avoid sharing data that compromises security. For example, when capturing images or videos of others to post on social networks, it is necessary to obtain their consent.
However, there may be times when we are recorded without permission in a location with hidden cameras, which is an invasive act. There are probably legal proceedings for this, but you can solve this situation quickly with a simple trick that only requires your cell phone.
How do you know if there is a hidden camera in a room?
This trick is possible with phones running the Android operating system, but also with iPhones, so anyone can use it.
It is important to remember that surveillance cameras have a night vision function, so they are able to capture images in dark rooms thanks to infrared light technology. To detect it, you have to rely on the ToF (Time-of-Flight) sensor of your phone's camera.
To discover a hidden camera, you need to test the front and back lens of your phone. In this way, the ToF sensor will help you accurately measure the location of the hidden camera emitting infrared light.
Turn off all lights and point your smartphone camera at your surroundings, as if you were recording. If you see infrared on your screen, it means you have found a hidden camera.
Some safety tips: record with the flash on and then examine walls, outlets, furniture and anything else that looks suspicious.
