As if we were an aspiring James Bond, it is possible to use our smartphone for many tasks and one of them is to discover, if we have the suspicion, if in our house or in our work there are hidden cameras somewhere, and regardless of whether What we have is an iPhone or an Android phone.
It may seem like a spy movie, but the truth is that, above all, in the field of work they may be recording us without our knowing it – although we have given authorization for it -. And more worrying is if someone has hidden a camera in our house without having any idea of it you can also use hidden camera detector apps on your mobiles to spy others, but it would not be weird the case of some “voyeur” with certain knowledge.
Whatever the casuistry, or out of simple curiosity and desire to entangle with our mobile, we have two ways to discover thanks to the terminals if there is a hidden camera. The first is detecting electromagnetic fields since, in most cases, these cameras are connected to the Internet, in addition to being using electricity, they emit a certain type of radiation. This is especially useful for discovering hidden cameras in a wall or an object (the typical teddy bear, for example). The second method is detecting the reflection of light from a lens. It is a somewhat less reliable method but, perhaps, it is the best to confirm our suspicions next to the first mentioned.
But we are going to the mess, obviously, what we are going to need are a series of applications. We will start with what are called Hidden Camera Detector, that although they share a name in iOS and Android are not the same and in fact, in iTunes it is paid while for Google software it is free.
Both work in a similar way, activate the application and move around the house in search of electromagnetic fields. It is clear that if we are crossing with routers and other devices, the oscillation will vary but the algorithm of the application is prepared to eliminate those frequencies that, supposedly, are other devices. You have to go looking and when the figure on the screen exceeds 100 points, we have found a hidden camera.
The application in Android has an “infrared” mode (IR Mode) that makes it look for hidden cameras in this part of the spectrum and what we need to see is a bright white disk on the screen, although it is much less precise.
Do you think you can be being spied on? Are you going to try these applications?
Although it may sound strange, yes, your smartphone can analyze the environment for the detection of hidden video surveillance cameras. It can be done through a simple application, and the system used is as simple as the analysis of radiation in a limited field. And, although there are dedicated teams that far exceed 100 and 200 euros for this type of ‘missions’, thanks to the antennas that incorporates a smartphone is able to offer exactly the same.
Your smartphone can analyze radiation from a limited environment
The analysis of radiation, as such, is what allows the smartphone to connect to mobile phone networks. Precisely for this reason, applications that are designed for this type of detection of hidden devices, have an algorithm specially designed to omit the ‘noise frequencies’. That is to say, they eliminate the electromagnetic radiation of mobile telephony towers from their results, as well as any other device that is not a video surveillance camera. Even the radiation of the Earth.
An algorithm that eliminates radiation results that do not come from hidden cameras
In this way, with the algorithm we talked about, these applications are capable of returning, in their ‘radar’, only the results of video surveillance cameras in the environment we are analyzing. And the best of all is that, at least on Android , we can download the application for free. In iOS , however, the alternative that we have available is paid.
It has advanced tools for all types of video surveillance technologies
In addition, in the app that is available for Android we have some more information available, and another type of analysis such as the search for infrared cameras. Therefore, although it is an application for somewhat singular uses, the truth is that it is worth taking a look, if only out of curiosity. And as is evident, we can not only use it in closed environments, but also in the open air, although here it is more difficult to achieve such precise and reliable results.
