Laser Microphone

 

We are demonstrating targeting a car license plate approximately 250 meters away through double glazing.
Of course, it is also possible to clearly listen to high-quality conversation audio inside the car.

Portable/ In door Laser Microphone

 

Description
The Portable/ Indoor Laser Monitoring System can collect nano- scale vibration information ( caused by sound) of different items by laser under the condition of long distance and noisy environment, and then restore clear sound by algorithm.

Wireless Stereo Through Wall Listening System

 

Description:
Multi-function Stereo Listening system can receive and record analog sound signals (human voice, footsteps, other sounds). Due to the adoption of reflective low-noise DSP processing and amplification equipment, the signal is picked up by the left and right independent stereo sensors in the front end, and output after demodulation by the control processing unit in the back end, so the system can detect very slight sound.

Please review the information below, and I look forward to hearing your thoughts.

The Stealth TEAM
The Stealth TEAM was developed based on more than 30 years of practical TSCM (Technical Surveillance Counter-Measures) operational experience. Its primary objective is to enable operators to detect, identify, and locate RF transmitters more quickly, more accurately, and more easily than with conventional TSCM equipment.
For example, if the system detects a suspicious frequency-hopping digital transmitter operating around 862 MHz, the display immediately indicates "Digital Eavesdropping Suspected." Likewise, if a suspicious analog transmitter operating around 398 MHz is detected, the display shows "Analog Eavesdropping Suspected."
These threat descriptions are fully customizable. Operators can rename them according to their operational requirements, using terms such as "Credit Card Bug," "Eavesdropping Threat," or any other terminology that best fits their procedures. This enables personnel with limited RF expertise to immediately understand the situation and respond appropriately.
A standard Stealth TEAM system consists of three Stealth 24/7 monitoring units (sensors) and a central monitoring workstation.
There are two primary reasons for using three monitoring units.
First, the system performs real-time triangulation, allowing the location of an RF transmitter to be determined immediately. If the transmitter moves, the system continuously updates and tracks its new position in real time.
Second, because the three monitoring units are permanently distributed throughout a large office or conference room, operators no longer need to walk around carrying portable detection equipment, as is required with conventional systems such as the Oscar Blue or Delta X G2/G6.
Today, most sophisticated eavesdropping transmitters can be activated remotely. Therefore, security inspections should not be limited to a sweep immediately before a meeting. Continuous monitoring throughout the meeting has become increasingly important.
With the Stealth TEAM, the three Stealth 24/7 monitoring units remain installed inside the conference room while the security officer monitors the system remotely from outside the room. If continuous visual monitoring is impractical, the system automatically sends SMS alerts to the security officer's smartphone whenever predefined threat conditions are detected.
For Wi-Fi surveillance, the system continuously analyzes SSIDs, MAC addresses (BSSIDs), and other wireless parameters to immediately identify newly appearing wireless devices.
We believe these capabilities represent a fundamentally new operational concept compared with conventional TSCM equipment. The Stealth TEAM was designed and developed entirely in-house based on more than three decades of real-world operational experience.
***To further enhance operational reliability, future deliveries of this system will be equipped with a specially manufactured military-grade monitor instead of the standard display. This upgrade offers superior durability, reliability, and performance for professional and mission-critical applications. (Please refer to the attached photograph.)
The Stealth 24/7
The Stealth 24/7 utilizes the same monitoring technology as each sensor unit of the Stealth TEAM.
It is designed for permanent installation in VIP conference rooms, executive offices, government facilities, military installations, and other high-security locations. All monitoring units can be connected via the Internet to a central monitoring station, enabling continuous 24/7 remote supervision.
Whenever three or more Stealth 24/7 units are installed within the same protected area, the system automatically determines the location of an RF transmitter through real-time triangulation
The Stealth LA-5000 (Speech Protection System)
One of the most significant advantages of the Stealth LA-5000 is its proprietary transducer technology, developed entirely by our company.
Modern buildings are typically constructed with laminated or double-glazed glass, which exhibits vibration characteristics that are significantly different from those of traditional single-pane glass when subjected to laser eavesdropping.
Over many years, we have conducted extensive testing using actual laser eavesdropping equipment and developed a dedicated transducer specifically optimized for these modern glass structures.
Unlike conventional products that rely solely on piezoelectric vibration, our transducer combines piezoelectric excitation with additional mechanical vibration. Furthermore, the vibration characteristics continuously change in accordance with the masking signal, creating highly unpredictable composite vibrations across the glass surface.
As a result, the system provides significantly enhanced protection against laser microphone eavesdropping attacks, delivering outstanding speech privacy even in modern buildings equipped with laminated or double-glazed windows.
And
The Stealth Encrypt operates in digital (AES-256) encryption mode by default. However, if communication quality temporarily deteriorates during a call due to external network conditions—such as when the two parties are using different mobile carriers or when the call passes through international networks—the system automatically switches to analog scrambling mode to maintain uninterrupted communication. Once network conditions recover, it automatically returns to AES-256 digital encryption without any user intervention.
Another unique advantage of the Stealth Encrypt is that all encryption and decryption processes take place entirely within the earbuds themselves. As a result, even if a smartphone is configured to automatically record calls, the phone records only the already encrypted audio stream, making the recording unintelligible and impossible to play back as normal speech.
In today's environment, disputes arising from recorded telephone conversations have become increasingly common. By preventing unauthorized or unintended recording from producing intelligible audio, the Stealth Encrypt provides an additional layer of privacy protection while helping to reduce the risk of misuse or disputes involving recorded conversations.

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

★ [GTG-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).

★​ [Counter Surveillance Equipment Range]

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.
