★ [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
*The range of frequencies generated 25,5 – 26,5 kHz
*signal level: 117dB
*Guaranteed jamming radius (all types of surveillance devices): 2 m, 360°
*Weight: 5 kg
*Dimensions: diameter- 230mm; height 110 mm
*Continuous operation time with battery power up to 2 hours

★ [GCU-OSD10] CAMERA OPTICS DETECTOR
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:
- GTG-OSD10 device;

★[The Stealth Druid-D06] Portable Audio Jammer & Speach Protection System
The Professional Portable Audio Jammer and Speech protection system
Not all listening devices can be detected by existing methods. Remotely controlled radio microphones, wired microphones, passive resonators, miniature voice recorders – practically all these devices cannot be detected by conventional methods. Even a modern cellular phone may contain a digital voice recorder; this means that any phone lying on the desktop could be used by an adversary to record a conversation.
The generated audio interference cannot be cleared by any noise-clearance methods. At the same time the produced interference does not create any inconvenience to the participants of the negotiation thanks to the special headsets. The DRUID headset allows users to hear each other with crystal quality. Each headset can be adjust the level of microphone and earphone for the individual user and environment.
