Miniature fiber optic microphone for indoor acoustic monitoring with extended frequency range response. Ideal where the footprint for microphone placement is severely limited or where the microphone is a sub-component in another device or system.
It is a very difficult element to detect in TSCM Counter Surveillance services because it doesn´t have electronic components, it doesn´t emit EMI/RFI and it is a perfect device for long-term monitoring.
Small, lightweight MEMS design
Absolute EMI/RFI immunity
Completely passive sensor with no metal or electrical parts
Cost-effective, long-term solution
Optical fiber connection over extended lengths without signal loss
Excellent sound accuracy
Standard analog output
Exceptionally low sensitivity to vibration
Miniature fiber optic microphone. The system comprises of an advanced fiber optic microphone 1mm PVC & single-channel electro-optic unit, for digital-to-analog conversion of optical microphone output signals. The Single Channel is extremely compact. It features a pair of fiber optic connectors; a 3.5 mm socket for analog output & green LED voltage indicator. Unit is powered by external DC power supply (8-15V).
The optical part does not contain metal nor active components; therefore it cannot be detected by conventional TSCM methods
Does not contain metal and is completely passive, therefore is immune to EMI/RFI
