The system can pick up sound through building walls, ceilings,
floors, Multifunctional Stereo Listening System
Model: HWCW-V
Description
The system can pick up sound through building walls, ceilings,
floors, etc. An external sensor is connected to an audio amplifier
that provides tactile volume control on the left and right
channels, as well as external USB flash drive recording. It is the
leader of the same kind of products by providing accurate,
sensitive and high-definition listening effect and recording year
and time. It can be heard through buildings such as walls, roofs
and floors, as in places where hostages are being held.
Multifunctional stereo audio system can receive and record analog
sound signals (human voice, footsteps, other sounds). Due to the
adoption of reflective low-noise DSP processing and amplification
equipment, the signal is picked up by the left and right
independent stereo sensors in the front end, and output after
demodulation by the control processing unit in the back end, so the
machine can detect very small sounds.
