They have found a new way to locate hidden micro-cameras, and you only need the TOF sensor of your mobile to use it, The cameras are getting smaller and smaller, and that is not good news for certain cases. This allows spy cameras to be much more difficult to detect , becoming invisible to the human eye. A good example of this are the devices that are sold to detect them on Airbnb.
Under this premise, several Researchers from the National University of Singapore and Yonsei University have worked on a system to detect these cameras through ToF sensors ( Time of Flight ) present on our mobiles.
The trick is in the reflections
The same people in charge indicate that there are already certain systems that detect the presence of hidden cameras by small that are, such as the analysis of the traffic generated through Wi-Fi networks. But these methods only indicate the existence of the cameras and not their location .
The proposed system is called LAPD ( Laser-Assisted Photography Detection ), and uses the lasers of the ToF sensors to locate the reflections that arise from the lenses of the cameras (these lenses return the laser to more intensity). As these lasers are designed to detect depths and help generate graphics in augmented reality environments, the only thing that would be needed is an application and an algorithm of machine learning .
In the application we would focus on the corners of a room in which we suspect that there is a hidden camera, and an augmented reality interface would tell us where it is. No special equipment or device would be required , as with other methods. With a modern smartphone and its ToF sensors it would be enough.
While looking for The naked eye detects an average of 46% of hidden cameras, the LAPD method has managed to detect a 88, 9% in the tests they have carried out . Bad news for those who place hidden cameras in certain places, of course.
