THROUGH-WALL LISTENING SYSTEM

Code: AI01092

High-fidelity audio system, using unique optical technology, to monitor room acoustics and allow listening through: concrete walls, doors and windows without having to be inside target area.

Main features:

• Non –detectable, tactical stereo surveillance kit
• Absolute EMI/RFI immunity
• Excellent sound accuracy
• High SNR optical microphone
• Structural – borne (through walls) contact microphones
• Dual channel EOU with DSP for real-time ambient noise reduction

Technology:

FOS senses microscopic vibrations results from sounds and noises inside the room and translates it into an audio signal. FOS is based on a unique optical acoustic technology. The FOM is built around a tiny MEMS membrane and two optical fibers.

When acoustic sound waves impinge on the membrane they cause it to vibrate, changing the intensity of light reflected from the incoming fiber to the outgoing fiber. Such precision translates into clear and low-self-noise sound, and produces exceptional microphone performance.

Application:

• Homeland security, designed for SWAT, special taskforces
• Stereo monitoring, high fidelity, binaural recording
• Structured (through -wall) monitoring in the audio range
• Standard indoor surveillance operations
