multifunctional stereo listening system built-in digital signal
(dsp) processing module
Multifunctional stereo listening system
Model:HWCW-Ⅴ
Description:
The device adopts the reflection low noise DSP processing module.
The signal (human voice, footsteps and other sounds) is picked up
through the left and right independent sensor probes at the front
end. After demodulation by the control processing unit at the back
end, the digital signal is output, which can detect very small
sound signals.
This device has high detection sensitivity and clear output sound
quality. It can better restore the sound through the dedicated
Bluetooth noise cancelling headset. It can pick up the sound
through the wall, ceiling and floor of the building. The equipment
can be used as fast monitoring equipment of special forces, but
also the military police forces, criminal investigation and
technical investigation departments of the investigation and
anti-reconnaissance necessary products.
Feature:
1.Highly sensitive independent sensor probe, can pick up weak sound
signals.
2.Built-in digital signal (DSP) processing module for sound
algorithm processing, to ensure the quality of sound.
3.Built-in system automatically adjusts the sound without manual
adjustment.
