The Stealth 12.4GHz Countersurveillance sweeping system

New countersurveillance sweeping system for detection of radio transmitting, wired and infrared bugging devices (frequency range up to 12.4 GHz).Uses digital receiver-spectrum analyzer. Sweeping speed is 50 MHz per second. Analysis of signals on 2 antennas provides detection of all local transmitters not depending on the type of modulation.


  • Quickly and reliably detects eavesdropping devices which use the RF waves, wires and infrared beams for transmission of information from the premises
  • Types of detected bugs: VHF/UHF radio microphones, GSM/3G bugs (GSM baby), digitally encrypted radio microphones, telephone transmitters, AC/telephone line/Ethernet currier transmitters, hidden video cameras with transmitters, microphones with transmission via the infrared beams, hidden electronic devices in objects
  • 2-antenna analysis provides quick selection of the RF signals originating from the checked rooms not depending on the modulation type
  • Measurement are accomplished with the help of the modern digital receiver, providing spectrum analyzing possibilities with the scan rate of 50 MHz per second at 12.5 kHz resolution
  • Detects intermittent (non-constant) signals with the help of the Sonogram function
  • Wide frequency range covered: 5 kHz -12400 MHz
  • Built-in low-frequency convertor provides features for inspection of the wires, electro-magnetic range and the infra-red range
  • Working modes: RF sweep, AC check, TLF check (telephone/low-voltage wire), IR check (infrared optical range), MLP check (electromagnetic probe), Detector-Locate
  • Detector-Locate mode allows the operator to find the physical location of the transmitter
  • Digital communication sources (GSM, Wi-Fi, Bluetooth, 3G, LTE, Wi-Max, etc.) can be inspected and located
  • Automatic data logging provides possibility to accumulate signal’s history during the searches
  • Wide set of graphical elements: Spectrum (current, max, min, remote antenna, threshold, etc.); Sonogram; IQ constellation; Oscilloscope; FFT-spectrum
  • FM/AM demodulation with selectable bandwidth
  • Analysis of the modulation in the IQ constellation window
  • Database stored in Microsoft Access format
  • Recording of demodulated audio



The spectrum analyzing technology used in the Delta provides the professional level of sweeping, giving full information about the radio frequencies being used in the area to the operator practically without necessity to move the equipment within the territory. The digital receiver used in the Delta has much longer distance of detection in comparison to the conventional RF detectors, so the sweeping procedure can be performed quickly and covertly, room by room. The system can be placed both inside the room being checked and in an adjacent premise to provide secrecy of operation.

The 2-antenna analysis used in the Delta allows you to detect RF bugging devices not depending on the type of modulation and encryption. Its working principal is based on the nature of radio waves to decrease power proportionally to the distance to the source. Signal on the close antenna will be stronger than the one received in the remote antenna. Such the DigiScan EX Delta system quickly selects the transmissions which originate from the inside of the premise. The system has a built-in high-quality antenna switcher.

After the sweeping the operator can perform the location procedure and find the exact location of the bug.

In addition to the RF analysis the Delta has the possibility to check the wire communications, infrared range and electromagnetic range for presence of illegal signals. For this aim the system includes a low-frequency converter.

The Delta system and its software DigiScan EX have a simple intuitive interface and do not demand special knowledge from the operator. Typically the operation is performed in 3 stages: 1) placement of the antennas or probes; 2) pressing the corresponding operation button; 3) watching the results. At the same time professionals will find many high-grade possibilities and settings, which can be useful for deeper learning of RF environment at a further usage.
