Live without fears to live better:

Verifying if your home is hiding microphones or spy elements is not a paranoid act. 

Do you feel followed, listened to, or filmed? 

Surveillance within families is becoming increasingly common and spying on one’s family has become easier with GPS trackers, spy microphones, and hacked phones. 

What are the most common cases encountered? 

  • Conflictual divorce 
  • A malicious friend 
  • A jealous spouse 

Today, obtaining sophisticated spy tools is easy. These can be tiny microphones, cameras, or everyday items that hide objects allowing for surveillance. 

Some shops manufacture custom-made spy microphones and cameras, allowing them to be placed inside objects in your home. 

The fact that no new objects are found in your home is therefore not a guarantee of confidentiality. 

What are the techniques for spying on your privacy? 

A micro or GPS tracker may have been placed on your vehicle, allowing you to track your movements and listen to your conversations. 

These systems use GPS signal to position themselves and GSM or Lora/Sixfog network to communicate their position. 

AJT DETECTIVE helps you protect yourself against attacks from outside and inside.

Why use our services in this matter? 

There are tools for detecting spy microphones or cameras. However, we caution you that to carry out an effective “dust-off,” you need to handle and exploit expensive and difficult to obtain equipment. 

In fact, the tools offered to the general public are often ineffective and do not guarantee an infallible result, allowing you the peace of mind you claim.  

During our interventions, we carry out: 

  • Check of furniture and decoration

  • Check with a non-linear junction detector to detect all types of hidden electronic equipment, whether they are under tension or not 

  • Analysis of telephone wiring by reflectometry (continuity, isolation…) 

  • Check of analog and digital telephone outlets 

  • Search for analog, digital, infrared, and laser microphones 

  • Search for deviation on line 

  • Search for recording or any other equipment that would allow ambient or remote listening (several thousand km) 

  • Search for wired hidden micro-camera 

  • Search for microphones on power carrier and analog and digital microphones

  • Search for Bluetooth devices 

  • Check of each telephone station and its connection to the network; this is an analysis by reflectometer 

  • Check of telephone and power cables 

  • Search for DECT networks

  • Analysis and demodulation of audio and video signals allow detecting and locating a radio emitting source from 9 kHz to 6GHz 

  • Search for series or parallel mounting (splitter, microphone, infinity…) 

  • Search for wired listening system 

  • Search for recording system (tape recorder, MP3 recorder); A recorder allows remote listening (several thousand km) 

  • Analysis of the activity of 2.4 GHz and 5Ghz frequencies, allowing to detect and measure all wifi sources: 

  • network mapping, machine port scanning, access point searches, wifi microphone searches 

  • Search for wired and wireless video surveillance system (mini camera, etc.)

  • Search for self-powered car microphones 

  • Analysis of the vulnerability of access points…

How much does it cost to detect spy microphones, cameras, or GPS trackers? 

The fee for this type of intervention depends on many parameters. 

To provide you with a precise quote, we will ask you for information such as the size of your home, its configuration, the number of floors, the amount of high-tech equipment and telephone lines.

Value your work! Work without fear!

It is not paranoid to want to verify if your company is hiding microphones or spy equipment. 

Do you feel followed, listened to, filmed? Does someone from your company talk to you about things they should not know about, directly or indirectly? Do you feel like your competitor is spying on you?  

Today, it is easy to obtain sophisticated spy tools from a shop. They can be tiny microphones, cameras, but also everyday items that hide objects for your surveillance. 

Some shops manufacture custom-made spy microphones and cameras, which can be placed inside an object in your premises. 

The fact that you do not observe new objects in your company is not a guarantee of confidentiality. 

What are the techniques that can be used to spy on your professional life? 

Confidentiality is one of the values necessary for a company to function well. To allow your colleagues to work peacefully in their workplace, to allow your customers to feel secure about the data they provide to you, and to protect your company’s commercial strategies, you must ensure that your premises are not being spied on.  

Also, be aware that a microphone or GPS tracker may have been placed on your vehicle, allowing for tracking of your movements and listening to your conversations. 

These systems use the GPS signal to position themselves and the GSM or Lora/Sixfog network to communicate their position. 

AJT DETECTIVE helps you protect against attacks from the outside and inside.
