Laser Listening Device

详情

The Laser Listening System (FGLD***6) can listen the sounds of more than *0 dB from the distance up to ***0 Meters line of sight (LOS) from a precisely focused glass 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. It also has a special high powered lens **8nm for cancellation of ambient optical noise. 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 *2 hours can be achieved by each battery (Depending the volume gain). The weight of the total system with packaging is approximately *5 KG.


The FGLD***6 is a standalone unit and can be placed on a tripod and can be hand held for short time of use.
