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 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.

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) email 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.

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.

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.
