Multifunctional Listening Through Wall System
Product Description
Multifunctional Listening Through Wall System This cutting-edge system is equipped to capture and document analog audio signals, such as human voices, footsteps, and other sounds with remarkable precision. Utilizing advanced reflective low-noise DSP processing and amplification technology, it employs left and right stereo sensors to independently capture signals at the front end. These are then demodulated by the control processing unit at the back end, enabling the detection of the faintest sounds.
This versatile system is designed to capture sound through various building structures like walls, ceilings, and floors. By connecting an external sensor to an audio amplifier, it offers precise tactile volume control across left and right channels, with the added convenience of recording onto an external USB flash drive. As a leader in its class, it delivers unparalleled accuracy, sensitivity, and high-definition audio capture and recording capabilities, complete with date and time stamping. Ideal for scenarios such as hostage situations, it provides clarity through challenging structures like walls, roofs, and floors.
Beyond its role as a rapid-response monitoring tool for special forces, it is also indispensable for criminal investigations, technical surveillance, and counter-intelligence operations, making it an essential asset for investigation and anti-surveillance units.
