Perfect in all conditions

The device has an infrared laser together with advanced DSP technologies. This allows perfect speech detection and ensures excellent quality of the collected sound, even in noisy environments. It allows operation from different angles and on many surfaces. In addition, the microphone has a wide operating range with minimal laser power. It is simple and easy to use.

Effective on any surface

The sensor can pick up vibrations from almost any type of surface. However, it performs best on soft, thin and lightweight objects. Simply aim the laser at a painting on a wall, a cushion or window pane, or even clothing, for the laser beam to convert the vibration into an electrical signal, which is amplified to be heard. Manual focus adjustment allows operation at distances from 15 m to 300 m.

Sound quality protection is achieved with the headset. The device offers up to three sensitivity levels to achieve optimum signal quality. To facilitate accurate laser targeting and quick set-up, the kit includes all the necessary accessories for this.


The GMD2200NEO laser microphone consists of an infrared laser sensor and a monitoring unit. The unit also features a high-precision interferometer that superimposes two coherent waves, which amplifies sound vibrations, and a built-in parallax-free colour camera. The image in the lens is therefore consistent with the indicated image. The camera provides an image of the target zone with a central scale grid.

The image focus can be adjusted using the focus ring on the lens. In cases where light levels are low, it is possible to use the mechanical sensor interface to adapt it to the night vision scope.

Fully safe device

The laser is invisible to normal cameras and the human eye, making it safe for vision. The laser source in the sensor meets Class 1 requirements to prevent eye injuries.
