Laser Mics have being around for a while and all do carry some limitations.
However if you know their limitations and advantages they can produce results .
In general these products shoot a laser beam to the window surface and the produce receiver translate the laser vibration to audio .
One of the issues is the angle of the laser with the window (90 degrees offer best results) the distance to the target , and the environment buzz that can can mess up any good audio reading.
Ideal conditions will be at low noise environment at night time within 500 yards from target .
This product is restricted to Federal buyers only.
