Multichannel Optical Acoustic Microphone
Stand-off Laser Microphone for covert surveillance and Evidence collection
Range up to 150 meters. Can be used with any angle of direction.
The sound quality is several times higher than of OAM-2000
Unlike the OAM series, the laser spot is processed immediately by 2 or 4 high-speed cameras, collected into a single picture and cleaned, which allows to achieve the best sound quality.
Removes information not from the glass, like other similar devices and with the laser spot with any items - paper, plastic, kitchenware. So that can be used at any angle to the target.
Currently there are no analogue on the market
• Acoustic surveillance and observation up to 150 m without entering the location of conversation
• The spoken word will be picked up from any cooperative material like paper, metal, plastic, textile, etc.
• Independent form angle of incident
• Easy to control: emitter and receiver in a single optical unit. Quick setup and targeting using an integrated, parallax-free camera
• Invisible eye-safe laser beam; unparalleled noise performance ratio with low laser power
• No interferences from surrounding noises; not influenced by noise between sensor and target
• Works even with lowest vibration of surfaces allows monitoring through a glass window into interior spaces, i.e. into cars or rooms
Low noise floor
A multichannel receiver and advanced signal processing techniques produce audio that is clear and easy to listen to, free from loud pops, crackles and drop-outs.
Laser power rises as a function of range. Reserve power is available to extend range beyond 150m with consequential loss of audio quality.
Tolerance to motion
MOAM unique processing algorithms greatly
reduce the effect of platform or target motion. By minimizing disturbing noise caused by movement,
MOAM expands deployment options and increase
suitable audio targets.
The operator aims the sensor head at the audio target using the riflescope, adjusting the range to obtain the clearest speech movement and tone.
The sensor head transmits an invisible infra-red laser at the audio target and a very small amount of reflected light is captured via two receiver lenses.
Sound waves around the audio target cause tiny movements which are detected be the receiver unit, demodulated by the processor and output as intelligible audio.
With the optional remote-control unit, the user can bookmark known good audio targets for rapid re-targeting. Streaming video an and audio can also be recorded on the laptop as evidence.
