The WE M70 LASER MIC is a professional piece of equipment allowing the operator to carry out undetected surveillance from outside a building.
Thanks to its unparalleled features, the WE M70 LASER MIC is able to pick up room audio from a distance without even entering the target room: by demodulating the transmitter IR laser beam bouncing from the target window, this equipment can receive and subsequently convert into electronic signals the slight window pane vibrations caused by acoustic waves in the room (voice speech).
Laser beam bouncing off the target window is then converted into electronic signals, then filtered, amplified and fed into a dedicated recording unit connected to its own amplifier with speaker/headphones: real time audio monitoring and recording are possible at the very same time.
The whole system operates according to the Snell's law, which requires sharp alignment and correct aiming of both the transmitted and received laser beams: to simplify both set up and alignment procedures as well as ordinary operation of the system, we have provided the WE M70 LASER MIC with sturdy tripods and a special search tone device which proves to be outstandingly valuable and absolutely necessary owing to the fact that emitted laser beam is totally invisible to the naked eye.
Although the operating principles, performance, technical specification and accessories stay the same, two different models are available: basic and camera. When maximum concealment is paramount, the WE M70 LASER MIC camera (pictured aside) is to be preferred.
