ST 107 - Ultra Wide-Band Professional RF Detector

The ST 107 RF Detector (BUG Detector) is designed to detect and locate the sources of electromagnetic radiation from surveillance devices (eavesdropping devices), such as:

  • radio microphones (Bugs);
  • telephone transmitters;
  • radio-stethoscopes;
  • hidden wireless video cameras;
  • radio beacons;
  • tracking devices;
  • unauthorized use of GSM and DECT cellular phones;
  • unauthorized use of Bluetooth and 802.11 (WLAN, WiFi) devices.
  • identifi cation of a signal 802.1g and base DECT is added;
  • USB port;
  • Built in Li-Pol accumulator.

 

The ST 107 utilizes the principles of wideband detection of electric fi elds. The ST 107 operates in three main modes: Search, Monitoring, Log view.

 

 

Search Mode

This mode is intended for detecting sources of electromagnetic radiation.


In this mode, the ST 107 receives radio signals, detects them, and outputs them to the built-in display and as an audio signal to the earphones and the built-in speaker. The level of the signal is indicated on two 32-segment level meters on the display.


Adjacent segments light up to indicate the average value of the level of the detected signal, while a single lit up segment shows its peak value.


The ST 107 can measure current frequency values of the radio signal and determine its most stable value (for signals with a constant carrier frequency).


The ST 107 also displays the detection of GSM, DECT, Bluetooth, and 802.11g (WLAN, WiFi) signals.

 

Monitoring Mode

The Monitoring mode is intended for detecting sources of electromagnetic radiation and storing data in NVRAM. The maximum number of events that can be stored in NVRAM is 4,096. The events can be viewed when the detector is in the Log View mode.

 

The Monitoring mode has an extended range of alarm signals, which can be triggered if the signal passes a certain level or frequency threshold, or if a certain type of signal is detected(GSM, DECT, Bluetooth, 802.11). It is possible for the user to schedule the ST 107 to turn on and off .


This mode has two basic operations:

  • User controlled operation: the ST 107 is placed so that it isvisible to the user. This is useful for detecting devices for the unauthorized obtaining of information among the visitors of an offi ce, for example.
  • Autonomous operation: The ST 107 is placed in an area where the use of eavesdropping devices is suspected, and the electromagnetic environment will be monitored during a pre-programmed period without user interference.

 

ST 107 PC Software intended to:

 

  • Display real-time data and the resuts of operation of the ST 107.

  • Load and display textual and graphical information of the
    operation of the device in Monitoring Mode (Event Log).

  • Operate the device remotely from the PC.
