Through wall audio listening device offering 15K sound amplification plus headphones and integrated 100 mAh battery for effective covert monitoring. Capture sounds from behind walls discreetly and effectively. This professional spy through-the-wall listening device is a reliable solution for discreet sound monitoring through various solid surfaces. The device is designed for easy and quick use, just place it against the wall, connect headphones and turn the control knob to activate the listening function and adjust the volume. An ideal solution for situations where you need to obtain audio information from behind an obstacle, without the need to physically enter the space.
The battery is charged using a USB charging cable (included). The through-the-wall listening device is a compact device that allows you to listen to conversations in the next room.
Thanks to the integrated highly sensitive contact microphone, which works on a similar principle to a stethoscope, the device can pick up even subtle vibrations that arise during conversations or other sounds on the other side of the wall. Inside the microphone is a special probe with a needle that converts mechanical vibrations from solid materials into an intelligible audio signal.
The listening device allows you to hear through any solid surface, such as concrete walls, drywall and pipes. This device can also be used to locate people trapped in the rubble of a collapsed building, in elevator shafts, underground, or in other emergency situations. Before use, charge the device using the supplied USB cable. Using the listening device through the wall is very simple. Connect the supplied headphones to the device and place the device on the wall. Turn the knob to turn on monitoring and at the same time turn the knob again to adjust the desired volume.
