★ [GTG-ZERO]   New Generation of High Grade           Smartphone Scrambler


GTG-ZERO is a device used for effective protection of rooms (conference halls, offices, rooms for meetings etc.) against the possibility of eavesdropping on talks that take place in them and that constitute official, business or private secrets. GTG-ZERO emits inaudible acoustic signal, in fragmentary narrow bands of acoustic and ultra acoustic sound.


The components of the emitted sound are mixed in a randomly variable way, with the aid of specially developed algorithm. This signal acts physically on microphones of audio devices, causing their resonance, thus making impossible the clear recording or playing back of all kinds of received acoustic signals. In particular GTG-ZERO blocks the operation of analogue and digital eavesdropping devices, dictaphones, voice recorders built into mobile phones, etc. The emitted interfering signal has all round feature (360°) with the guaranteed jamming of all types of listening and recording devices effectiveness within 2 m radius from the GTG-ZERO


[Technical data]

*The range of frequencies generated 25,5 – 26,5 kHz

*signal level: 117dB

*Guaranteed jamming radius (all types of surveillance devices): 2 m, 360°

*Power: 12V/220V/230V-50HZ

*Weight: 5 kg

*Dimensions: diameter- 230mm; height 110 mm

*Continuous operation time with battery power up to 2 hours

*Continuous operation time with 230V AC power supply - 5 hours

*Automatic shut-off after 2 hours of operation


[Set contains:]

GTG-ZERO, charger 18 V DC/230VAC, 2x remote control, user manual, transport case.


[Turning on the device:]

The GTG-ZERO device can be started in the 230V AC mains mode or in the internal battery supply mode.


[Switching ON in mains operation mode:]

a. Connect the charger to the device Jamming indication Jamming disabled Connecting the charger Charge level indicator ON/OFF

b. Switching ON the device with the "ON" button

c. Run the jamming function with the remote control.


[Switching ON in internal 12 V battery mode]

a. Switching ON the device with the "ON" button

b. Run the jamming function with the remote control.


[Switching OFF]

a. Switch OFF jamming function use the remote control

b. Switch OFF the device with the "OFF” button.


[Useful tips:]

GTG-ZERO device - it should be placed in the middle of the table, where sit people running conversation. Other placement of the device result in limiting the possibility of effective jamming. In the case of large tables, it is recommended to use two or more GTG-ZERO devices

★ [Encrypt] Text + Voice and Video Encrypt !!            High Grade Military encryption engine!



GTG-OSD10 is designed for search and visualization the place of portable systems of secret observation (SOS - Secret Observation System), camouflaged in the various items, clothing, working or disconnected compact cameras under different lighting conditions at distances up to maximum 750m. (depending on weather condition).


Basic operation principle is "cat's eye" effect (light-reflecting effect) lying in ability of optical objects to reflect probing radiation in opposite direction with angle close to its incidence angle. Semi-conducting laser IR diode (transmitting channel) serves as the source of probing radiation. The reflected signal is registered by sensitive video camera on the basis of interleave transfer sensor (reception channel). The Device is developed on non-parallax optical scheme, i.e. with optical alignment of reception and transmitting channels.


Transmitting channel generates laser beam in the form of vertically located rectangular raster. Ability of illuminating raster can be changed if necessary, depending on distance to surveillance object, for reception of the best image contrast. Image focusing on sharpness is carried out by adjustment of video camera objective.

Visualization of surveillance objects is carried out through built in pseudo-binocular. In order to receive better images, the body of the Device is equipped with fastening and connection for external 5"LCD-monitor (delivered on request of the Customer), and with external CCIR standard video signal socket for connection with external monitor, video recorder or computer (with video capture card).

GTG-OSD10 Delivery set includes:

  1. GTG-OSD10 device;
  2. Video cable;
  3. Optionally LCD-monitor (with attachment bracket);

The HSA-Q1 is a fully integrated portable RF Spectrum Analyser designed specifically for professional countermeasures use (TSCM).


It has been designed with the highest possible technical specification to ensure maximum detection capability and has a range of invaluable features to aid countermeasures RF detection or ‘Sweeps’. Despite its technical capability the HSA-Q1 remains easy to operate with an intuitive user friendly interface. 

HSA-Q1 features a wide 1 MHz to 13.44GHz frequency range with a sweep time of just 0.5 seconds (faster in shorter spans) to ensure detection of all types of RF signals especially modern pulsed burst signals that can be missed by slower sweeping units.


Frequency spans can be set anywhere from the whole 13.44 GHz range down to just 25 Mhz when detailed signal analysis is required. Simply move the cursor onto any detected signal and press the ‘Zoom’ button to view the signal in more detail.

The Waterfall (Spectrogram) function shows a real time full colour graphical display of any detected signal to allow the user further analysis. This is especially useful in analysing modern pulsed digital signals (or frequency hopping signals) such as those from Cellular, Wifi, Burst and GPS based devices.

★ [The Stealth P-1206]


The most advanced counter surveillance device



The Stealth 1206 can detect typical RF bugs and the modern hidden bugs which use the protocols of WiFi/Bluetooth, GSM and DECT.


Such bugs, especially Bluetooth types, are practically undetectable by common RF detectors due to their very low transmitted power and a special type of modulation.


The Stealth P-1206i uses a separate channel with a high, (2.44GHz) frequency pre-selector to detect and locate Bluetooth and Wi-Fi with a much higher sensitivity. The unit also then processes the demodulated signal in order to identify which protocol has been detected. In addition the unit can detect all ‘classical' bugs and inspect them for the presence of correlation by sending sound impulses.


- Detection of Bluetooth, Wi-Fi, DECT and GSM900/1800
- The perfect tool for searching for digital and analogue transmitters
- Frequency range:
        Main antenna  50-4000 MHz
        Auxiliary antenna 2.44 GHz
- 16-segment bar graph indicator
- Indication Method: 3 Modes - sound, vibration and mixed
- Discovers FM-transmitters by correlation probing sound
- 2 levels of sensitivity (attenuator)
