Eavesdropping Options

Types of eavesdropping technology
New methods of “listening and watching” with the help of modern technologies is widespread in our time. For example, a tiny GSM transmitter is accessible in virtually any Internet spy shop for as little as 100-200 francs, and it can easily eavesdrop on all your conversations in the office or at home. Perhaps even more important is the Bluetooth protocol, it is specially designed to transmit voices or conversations with high quality at a distance of up to 100m, it can be easily used for eavesdropping.

Illegal transmitters have a number of typical signs, they are:

Compact, Hidden, Handmade or Produced with small amount containing microphones or video cameras, implanted in another electronic device, connected to a telephone line, connected to AC wires or with its own power source. With an antenna. With inserted SIM card.

The following are the most likely ways to eavesdrop on wireless protocols:

GSM – WCDMA – 3G – LTE

GSM baby-monitor/GSM alarm/GSM bug

A small box with a SIM-card insert. Can transmit acoustics or conver- sations from a landline telephone to a pre-programmed number via the GSM network. Can be controlled form a pre-programmed number with the help of SMS or programmed from a PC. It is powered from a mains supply and has its own rechargeable backup battery.

GSM/GPRS/EDGE/3G/LTE
Video camera

Has a built-in video camera and can transmit captured still images, video and acoustics. It is usually used for security observation but can also be used for illegal bugging. On the GSM  network  still images can be transferred with the use  of  GPRS/EDGE,  but  3G allows for the passing of real-time videos.

Spy phone

A cellular telephone converted into a ‘spy phone’ with the help of spe- cial, illegally installed software. The software allows the illegal listener to activate the microphone of the telephone and transmit acoustics to a pre-programmed number. The control of this device   is accompli- shed in a similar way – by SMS or from a PC.

GPS tracker

A small device which can be installed in a target’s car or hidden among their items for personal tracing. Detects its own coordinates with the help of a built-in GPS receiver and then transmits them with the help of the GSM/3G network or can record a trace into its built-in memory. Most of these devices also have a built-in microphone and allow the operator to listen to acoustics in addition to knowing its coordinates.

Bluetooth

Bluetooth eavesdropping device

A small device that is limited in size only by the desired battery source. If an external power source is specified, these devices can reach a size of 1x 1x 0.5cm. They are hardly detectable by:

1) Low power, non-constant transmissions at relatively high frequency ranges; 2) The possibility of remote deactivation thanks to the duplex possibility of Bluetooth; 3) The ability to collect information and then transmit it by remote interrogation during the night time – that means that no radio waves are sent during working hours 4) Its small size.

Spy phone

Similar to GSM, the acoustics around the telephone can be picked up and transmitted via Bluetooth if the telephone has special ‘spy’ soft- ware pre-installed.

Spy mobile phone

Again, with pre-installed “spy” software in a mobile phone with Wi-Fi (i.e. a smartphone) allows the eavesdropper to hear the surrounding acoustics in real time, or they can initiate the downloading of pre-captured data.

Wi-Fi – Wi-Max

Wi-Fi bugging device

Can transmit acoustics or high quality videos using the standard wireless network. The information can then be easily forwarded onto the Internet and monitored from anywhere in the world. Controlling the device can also be done via the Internet.

Wi-Max bugging device

In addition to the possibilities provided by Wi-Fi, Wi-Max gives direct Internet access and a longer coverage distance. This can give the eavesdroppers practically unlimited possibilities in monitoring and control, including transmitting of acoustics, real-time video, remote controlling, collecting information with a fast transfer time, etc.

Telephone lines Telephone eavesdropping devices

When we talk about telephone lines, we should first mention GSM/3G/LTE(4G) eavesdropping devices that can record calls from a normal landline phone and then transmit over the GSM/3G/LTE(4G) network. It is also likely that a Wi-Fi/Wi-Max or Bluetooth channel can be set up to transmit the information.

Our detectors have been specially designed to detect all of these types of telephone interceptors.

Phone tapping devices can be installed wherever a telephone line is located. It can be within the phone set, phone socket, connector box, or cable. Most phone eavesdropping devices are only activated when the receiver stops working. Therefore, the examination of telephone lines should only be performed if the receiver is in this state.
