Portable Laser Monitoring system

Portable Laser Monitoring system

This monitoring system adopts the new third generation laser listening technology, which effectively overcome the problem of glass window’s black hole and realize to observe the target through windows. It can restore the sound signal in fidelity by continuously detecting the small vibration of low voice and impedance target. It is suitable to be used in closed, semi-closed windows environment or open space to effectively listen the person at a long distance.
