Specifications:

However the system is simple in operations but it needs very high degree of skills to tune properly. By understanding these issues FG offers at site trainings to the end-users, clients and organizations worldwide for its operations and handling in cost-effective way.

A thick 3 to 5mm Aluminum rugged casing is designed especially for military & tactical applications for the operating temperature range of -10 C to +55 C.

GPS Navigator is the integral part of FGLD-700 Series. This feature allows to the user to place the system on exact location as marked through the Digital map like Google? Map etc. For Using the GPS, system should be placed where Sky Visibility is 100% like play grounds or roof tops.

The FGLD-786 is a standalone unit and placed on a tripod and can be hand held for short time of use.

The laser transmitter and receiver are built in a special splash-proof mono block, allowing the system to be operated in inclement weather conditions. The state-of-the-art semiconductor laser is extremely mechanically robust and, due to its low power consumption, a running time of approximately 7 hours can be achieved by each battery (Depend upone the volume).  The weight of the Total system including Tripod, with packaging is approximately 25 KG.

The FGLD-786 has more function, it has a built in solid-state micro optical stabilizer for high immunity against vibrations.  It also has a special high powered lens from SIGMA Japan 680-850nm for Cancellation of Ambient Optical Noise.

The Laser Listening Surveillance System (FGLD-786) can listen the sounds of more than 60 dB from a long distance up to 1000 Meters Line of Sight (LOS) from a Precisely Focused Window in ideal conditions, but distance can be reduced by the natural and environmental factors like dust, snow, fog, uneven window surface, color glasses of the window and other optical interfaces like direct sunlight or due to flashlights etc. It is recommended to use this system in night time or in low light to achieve the maximum efficiency.

The Laser Listening Surveillance System (FGLD-786) is very sophisticated and sensitive electro optical equipment. It has to be used when access to a voice of more than 60 dB in a room is desired, which is otherwise impossible to hear. The laser transmitter, with its invisible 4.9 Watts infrared beam, has to be precisely directed at the angle of 180

FUSION's Reflected Beam Laser Listening Device can listen the sounds from long distance up to 1000 meters line of sight
