It Without batteries: 51x25x3 mm. operates as a Surveillance Transmitter used to gather conversations of a target and can be activated by Remote Control or Voice Activation. The RLM- 2 is an advanced surveillance tool that can be operated without the user's physical interfacing with the unit. That means the user does not have to go into the room and turn on the transmitter manually. GCOM listening devices such as the Sleeper Transmitter surveillance tool can be activated by remote control using a wireless signal or by voice (VOX). Surveillance tools such as the Sleeper Transmitter are used for capturing conversations and transmitting them to a Radio Receiver. Features Include: - Embedded Remote Control (almost invisible considering the small size of the transmitter) - Extended Standby Time (up to 4 years) - RF Stealth Technology... the RLM-2 does not give off Radio Frequency emissions in its standby (sleep) mode In addition, the RLM-2 works in analog NFM-mode, offering good operating distance with relatively low power output and power consumption. The RLM-2 Surveillance Transmitter uses Automatic Gain Control, providing good audio quality despite its operation in the NFM mode.

3 VOICE ACTIVATED TRANSMITTER Voice Activated Surveillance Transmitter model LM-1 is a covert room transmitter for audio surveillance used to collect conversations and transmit them Model # LM-1 VOX SPECIFICATIONS Working frequency: 433,500 MHz. Modulation: NFM, deviation 5 khz. 3V (CR2450), minimum operating Operating voltage: voltage 2,6 V. Power output: not less than 10 mw.

Estimating time of battery consumption at a) Constant transmission: 30h. +20C. Working temperature: Dimensions: b) Transmission /standby = 1/3 (8 hours per day): 120h 150h (5 7 days). c) Transmission /standby = 1/10 (~2,5 hours per day): 450h (> 18 days). 0С +50С. 25x25x3 mm without battery; 25x25x8 mm with battery (CR2450). to a Radio Receiver. It can be placed in a room or vehicle in order to capture and broadcast audio information or audio evidence for intelligence gathering purposes. This Voice Activated (VOX) Transmitter operates using Narrow FM (NFM). NFM gives off less 'noise' and causes less 'traffic' than other broadcast mediums. Using a Compander Circuit, the VOX Transmitter is able to transmit excellent sound quality comparable to WFM (Wide FM). GCOM VOX Transmitters use an effective micro-controller that starts the rf transmission once the voice activation circuit encounters speech or sounds. This is very powerful when every word that is spoken needs to be transmitted. In order to ensure the end of a conversation is transmitted, GCOM Voice Activated Transmitters are built with a long delay before shutting down into its standby mode. The lithium battery gives the VOX Transmitter a long operating time before replacement is necessary. The VOX Transmitter offers good operating distances with relatively low power output and power consumption. The VOX Transmitter uses Automatic Gain Control, providing good audio quality despite its operation in the NFM mode. The VOX Transmitter has built in microcontrollers which enable the Voice Activation feature. The Power (3V) is provided by lithium CR2450 batteries (alternatively by two AA batteries).

4 VOICE ACTIVATED MICRO- TRANSMITTER Model # LM-2 VOX SPECIFICATIONS Working frequency: 433,500 MHz. Modulation: 5 khz.±nfm, deviation 3V (CR2450), minimum Operating voltage: operating voltage 2,6 V. Power output: not less than 10 mw. Processor-controlled Voice Activation System (VOX). Automatic Gain Control System (AGC). Type of battery: DL2450 (Duracell). Working temperature: 0С +50С. a) Constant transmission: 30h. b) Transmission /standby = 1/3 120h 150h (5 7 days). (8 hours per day): c) Transmission /standby = 1/10 450h (> 18 days). (~2,5 hours per day): Dimension: 25x25x3 mm without battery; 25x25x8 mm with battery (CR2450 THE LM-2 VOX ROOM TRANSMITTER IS A MINIATURIZED VERSION OF THE LM-1 VOICE ACTIVATED ROOM TRANSMITTER. SMALLER IN SIZE, (ABOUT 4 MM THICK), THE VOICE ACTIVATED MICRO TRANSMITTER HAS AN EMBEDDED ANTENNA, REDUCING ITS VISIBILITY AND DETRACTING FROM UNNECESSARY ATTENTION. BECAUSE OF ITS SMALL SIZE, THE LM-2 VOICE ACTIVATED TRANSMITTER IS ABLE TO ASSIST THE USER BY OBTAINING THE CONVERSATIONS OF A TARGET, AND TRANSMIT THEM USING LOW POWER OVER A GOOD DISTANCE TO A RADIO RECEIVER. THE VOICE ACTIVATED MICRO TRANSMITTER CAN BE PLACED IN A ROOM OR VEHICLE FOR VOICE MONITORING IN ORDER TO CAPTURE AND BROADCAST AUDIO INFORMATION FOR INTELLIGENCE GATHERING PURPOSES. THE LM-2 FUNCTIONS PRIMARILY AS A ROOM TRANSMITTER, USING NARROW FM (NFM). NFM GIVES OFF LESS 'NOISE' AND CAUSES LESS 'TRAFFIC' THAN OTHER VOICE MONITORING BROADCAST MEDIUMS. USING A COMPANDER CIRCUIT, THE LM-2 IS ABLE TO TRANSMIT EXCELLENT QUALITY SOUND COMPARABLE TO WFM (WIDE FM). THE LM-2 USES AN EFFECTIVE MICRO-CONTROLLER THAT STARTS THE RF TRANSMISSION ONCE THE VOICE ACTIVATION CIRCUIT ENCOUNTERS SPEECH OR SOUNDS. FOR A ROOM TRANSMITTER, THIS POWERFUL FEATURE IS VITAL WHEN EVERY WORD THAT IS SPOKEN NEEDS TO BE TRANSMITTED. IN ORDER TO ENSURE THE END OF A VOICE MONITORING CONVERSATION IS TRANSMITTED, THE LM-2 IS BUILT WITH A LONG DELAY BEFORE WITHDRAWING INTO ITS STANDBY MODE. THE LITHIUM BATTERY GIVES THE LM-2 A LONG OPERATING TIME BEFORE REPLACEMENT IS NECESSARY. THE LM-2 OFFERS GOOD OPERATING DISTANCE WITH RELATIVELY LOW POWER OUTPUT AND POWER CONSUMPTION. THE LM-2 VOX TRANSMITTER USES AUTOMATIC GAIN CONTROL, PROVIDING GOOD AUDIO QUALITY DESPITE ITS OPERATION IN THE NFM MODE.

5 THE LM-2 VOX TRANSMITTER HAS BUILT IN MICROCONTROLLERS WHICH ENABLE THE VOICE ACTIVATION FEATURE. THE POWER (3V) IS PROVIDED BY LITHIUM CR2450 BATTERIES (ALTERNATIVELY BY TWO AA BATTERIES).

Surveillance monitoring using this listening device enables the user to monitor conversations of a target with a very small, discreet audio transmitter. This listening device is an investigative tool for monitoring conversations. The user may be present and take part in the conversation being captured by the listening device. The user may also be absent from audio surveillance operations. All that is required is to place the listening device in an area that no one would see it and the listening device would then transmit the conversations it hears to a surveillance receiver.

7 Digital Surveillance Transmitters The Digital Surveillance Series are able to send wireless voice and data as a digital stream. Features such as remote control operation, encryption, and stealth sleep modes are typical of the Digital Surveillance Series. Model # FLASH-1 SPECIFICATIONS Embedded flash memory: 244, 488 or 976 MB. Two record speeds: 32 kbit/s (LP) 64 kbit/s (HQ). Voice activation (VOX). Record time: up to 71h 04min (976 MB, VOX off, HQ).

GHOST VOICE INTERCEPT TRANSMITTER The Ghost Transmitter is a miniature surveillance tool used to capture audio surveillance conversations, store them in internal memory, and send them to the user for covert retrieval. The user places the Ghost Voice Intercept System at the location of the target. By remote control, the user activates the system. The system begins to record conversations within its proximity while the user can leave the area. When the user returns, the user sends a wireless signal to the system. The system then sends a burst of data to the user's Radio Receiver. This burst of data contains the target's audio conversations. The user now possesses the audio conversations, and can a) store them on a computer b) them as.wav files to intelligence officers and law enforcement agencies. The Ghost Voice Intercept System provides audio surveillance recordings into an embedded flash memory and transfers recorded information to the computer upon command. It does this by remote control and transmits wirelessly. This Data transfer protocol provides a high level of data integrity. The received information can then be saved on a computer as a.wav file, which can be playback by any multimedia player. Special software is included for loading the voice data transmission bursts.

This is a relatively simple but effective device for getting information of what somebody is typing on a pc keyboard. Because the Keyboard Transmitter is purely a hardware device, it can not be detected by software methods. The set consists of a transmitter and a receiver. The transmitter module is installed into the PC keyboard. The UHF-receiver receives the transmissions from the transmitter's dedicated modem module (the modem). A cable for connecting the modem to the UHF-receiver is supplied, as well as a cable for connecting the modem to a computer with software to load into the users computer.

10 Optical Audio Surveillance Access into target areas is not always possible. Secure and undetectable methods of monitoring are a necessity. The ability to covertly hear what is taking place is an invaluable asset, and because the use of transmitting voice is not limited to RF transmissions, Optical Audio Surveillance bridges the gap using infra red as well as laser light to transmit conversations. SPECIFICATIONS: Model # 4510-LASR LASER TRANSMITTER: OPTICAL RECEIVER LASER TYPE: Semi-conductor PIN Diode LASER WAVELENGTH: nm (near infrared) Near Infrared CURRENT CONSUMPTION: Approx. 150 ma, ma DIMENSIONS: 25x25x3 mm without battery; 25x25x8 mm with battery (CR2450). POWER OUTPUT: 5 mw 5 mw lens TYPE: 135mm 500mm POWER SUPPLY: 12 V, 8 x MN1500 "AA" Battery 9V, 1 x MN1604 Battery LASER SURVEILLANCE SYSTEM The G-COM Laser Surveillance System enables the user to capture conversations inside of a room using infrared light transmissions, optical and electronic sound wave demodulation hardware, and a harmonic filtration system. Theory of Operation: The G-COM Laser Surveillance System consists of a highly focused light sent over a distance and beamed onto the surface of a window of a building such as an office room, hotel room, apartment room, house, etc. This highly focused light (or infrared light) encounters a series of micro-vibrations on the window's surface. These vibrations originate from speech conversations as well as other sounds inside the targeted room. The window vibrations are caused by oscillating frequencies from sound waves that emanate from speech and conversations of the people in the room. Just like a diaphragm of a microphone, the window also vibrates and it is this vibration that the Laser Surveillance System picks up on. The infrared light then reflects off of the surface of the window and back to an optical receiver. This optical receiver is connected to an electronic demodulation system that converts the optical signals produced from the infrared light into sound waves. These sound waves are then filtered and can be listened to in real time, or connected to an external recorder for future review.

11 Q: How is the sound quality of Laser Surveillance? A: Under ideal conditions, the quality is good. Q: Is the system easy to set up? A: Yes with practice. The first time always is difficult. That is why the user is advised to conduct a few practice tests in order to become familiar with mounting and aligning the G-COM Laser Surveillance System for optimum results.

A miniature Infrared Transmitter converts sound into non-coherent pulses of light. Designed for easy sight alignment, the optical receiver is housed in a single lens reflex camera mounted onto a tripod. Light pulses are converted back into audio signals with high-density electronic circuitry which filters stray light emission for interference-free listening. A discreet audio-amplifier control module clipped onto a tripod leg filters out noise and increases the signals sensitivity and gain while a LED bar graph indicates signal strength. A miniature credit-card sized recorder permits simultaneous recording of all intercepted conversations. The G-Com Infrared Long Range Transmitter System includes miniature infrared transmitter, infrared optical receiver, audio amplifier control module recorder, headphones, tripod and mounting accessories. Optional lenses are available to extend range.

12 Concealable Transmitters Concealable Transmitters consist of room transmitter surveillance equipment, body wire packs, body wires, voice activated transmitters, mandown transmitters, wireless mics, tracking transmitters, and other selfcontained audio surveillance devices that monitor conversations when access to a room is limited. These free-standing units are battery powered and can be installed quickly, or simply dropped anywhere that discovery is unlikely, such as under furniture, behind a book, etc. A Body Wire is generally placed in a pocket and can be carried from room to room. Body Wires can also be inserted into clothing or taped under clothing for concealed audio surveillance operations. A Room Transmitter can be left under a table or counter, on top of cabinets or shelving, behind wall mounted paintings or pictures, etc. Man-Down and Tracking Transmitters from GCOM are used to track an individual's location, broadcast distress calls, and transmit audio surveillance conversations.
