The Portable Laser Monitoring System captures sounds from distances using an invisible laser beam and enables audio listening.

The Portable Laser Monitoring System is designed for listening to and recording sound information from ultra-long distances in a non-contact environment. Functioning as a ‘secret listener,’ the device can pick up sounds from up to 300 meters away. The laser monitoring system operates by emitting invisible light directed towards a target. When there are any sounds or vibrations in that area, the receiver captures the
reflected light, effectively recording the speech or audio signals present. The system provides a synchronous display of both far and near vision, allowing for real-time and rapid switching to enhance surveillance capabilities. It enables synchronous audio and video recording, storage, and playback in formats such as PCM and MP4, and is compact and portable.
