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.
