|Remote Information Collection Technology?
​
Privacy and security are important concerns of modern society. New technologies are constantly being developed to combat threats such as information theft and espionage. One of these technologies is laser microphones. Laser microphones use laser light to measure vibrations of a targeted area or object. In this article, topics such as the working principles, usage areas and safety concerns of laser microphones will be discussed.
|Working Principle
​
Laser microphones record sound waves by detecting changes in the reflection or reflection of laser light. Essentially, a laser light is sent to a targeted object or area. When this object or area is vibrated by sound waves, the reflection of the laser light also changes. The laser microphone detects these changes and recreates the sound.
​
When laser light is shined on a window glass, vibrations on the surface of the glass affect the reflection of the laser light. These vibrations are small changes caused by sound waves. The laser microphone can detect these changes and record the sounds heard on the window glass.

|Areas of Use
​
Laser microphones are often used for intelligence gathering and security purposes. In particular, they can be used in rooms or buildings where confidential information is transferred. When direct access to a microphone to listen to a target's sounds is not possible, laser microphones can be a useful alternative.
​
Additionally, laser microphones can also be used in remote monitoring or remote sensing systems. They can be used to record or listen to sounds spoken in a room.
|Security Concerns
​
The use of laser microphones can raise serious privacy and security concerns. Therefore, the use of laser microphones must be strictly subject to legal regulations and privacy standards.
​
Additionally, it is important to choose the right environment in which laser microphones will be used. In outdoor environments, vibrations caused by wind or other environmental factors can cause unwanted noise and make it difficult to detect the targeted sound.
​
Laser microphones are an effective technology used for remote information collection and listening. However, the use of this technology can raise serious privacy and security concerns. Therefore, careful consideration must be given to the use of laser microphones and legal regulations must be strictly observed. Illegal use may constitute a serious crime.
|Laser Microphone Blocking Systems
​
Devices placed on windows and producing white noise are generally used for privacy and security purposes. These devices are designed to make it difficult or prevent laser microphones from detecting sound waves.
White noise is a combination of random sounds over a wide range of frequencies. Devices that produce white noise emit a distracting and disturbing sound. This noise can make it difficult for laser microphones to detect or mask the sounds heard. Among our products, the DNG-2300 Model device is a very successful product designed for this job.
​
White noise devices placed on windows can be used in rooms or meeting rooms where particularly important or sensitive conversations are held. These devices can increase privacy and security by neutralizing the sound waves of laser microphones coming from outside.
White sound devices create a digital sound curtain on windows or surfaces by vibrating units placed on surfaces that are likely to cause vibration, usually small sizes of glass. The units placed on the edges of the glass or on the windowsill are generally powered by electricity.
​
These devices can be used as an important part of protective measures against laser microphones, careful placement and adjustment of white noise units is important.
