WHAT'S NEW FOR 2024 !!

Our company's flagship items are threefold. 

Global TSCM Group, Inc. has been manufacturing specialized equipment in the TSCM field for 28 years. We supply to various government agencies, intelligence agencies, and large corporations worldwide, and we exhibit new products at major defense exhibitions such as Milipol-Paris and Milipol-Asia every year. We also plan to participate in the Qatar exhibition in the second half of this year. Our company's main products are threefold.


Firstly, there is The Stealth 24/7, a fixed continuous surveillance device. This product differs from others commonly available in the market. Instead of performing spectrum analysis, it immediately displays 'digital eavesdropping suspicion' or 'analog eavesdropping suspicion' upon detecting eavesdropping frequencies. It also allows for swift location marking, which is practically useful for eavesdropping detection. Installing 1-2 units per VIP office enables the maintenance of crucial security for key conversations. Additionally, when eavesdropping frequencies are detected, real-time alarms sound at the central control center, and alerts are sent via SMS.


Secondly, there is The Stealth PRISON, a cellphone detector for prisons. It can be installed in each cell to detect unauthorized cellphones and usage.


Thirdly, we have The Stealth TEAM, a portable eavesdropping detection device. In fact, for this device, which consists of essentially three units of The Stealth 24/7, additional details are provided below.

The Stealth TEAM

Automatic Spectrum Analyzer Pinpointing the Eavesdropping Device Location 


Firstly, this equipment automatically analyzes without the need for practitioners to engage in challenging and meticulous spectrum analysis through wideband frequency scanning. It immediately displays suspicions of 'digital eavesdropping' or 'analog eavesdropping' on the screen.

In fact, through spectrum analysis, it is impossible to determine whether digital eavesdropping is occurring. Even I, Gyo seung An, who has been engaged in security measurement work for 28 years, nod in agreement to the difficulty of determining eavesdropping through spectrum analysis.


Therefore, after attending over 100 specialized exhibitions worldwide in the last 15 years and collecting advanced eavesdropping technology information, I have incorporated the results into our product, including digital modulation methods for each band and major eavesdropping frequencies. Secondly, through tracking the hidden eavesdropping device's location, we can easily and quickly remove the eavesdropping device.


This is achieved through triangulation, where frequency sensors are distributed across three zones for monitoring. Detected specific frequencies are downloaded to a separate search receiver to easily and rapidly identify those frequencies, irrespective of other frequencies.

The absolute function unique to The Stealth TEAM is the practical ability to track the location of eavesdropping transmitters in real-world scenarios. In other words, we can easily and quickly pinpoint eavesdropping devices.

Moreover, in specific cases, it is possible to detect the operation of my phone, unbeknownst to me, due to smartphone or spy app interference.


Furthermore, in cases of important meetings within the company or external venues like hotels, traditionally, security measurements were taken just before the meeting, and if nothing suspicious was found, it was deemed completed. However, The Stealth TEAM can place equipment inside the meeting room and monitor internal suspicions wirelessly from the outside or receive alerts via SMS.

Thus, even if security personnel cannot enter the meeting room, security tasks can be performed perfectly. Given that most digital eavesdropping devices are remotely operated from outside or automatically operated through event or weekly scheduling algorithms, such functions are essential.


This equipment can be used as temporary fixed monitoring equipment or mobile eavesdropping detection equipment without any shortcomings.


★ [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

★ [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).
