It is a microphone that uses fiber optics and does not use electrical signals, allowing it to capture sound without being affected by electromagnetic waves or interference.
As a new value of the optical fiber acoustic sensor developed for detecting abnormal sounds in harsh environments, this product is specialized for capturing voice. - The microphone part is made of plastic and does not use electrical signals, so it is not affected by electromagnetic waves. - The microphone cannot be detected by detection devices (it cannot be found). - Equipped with VOX and Time trigger (recording timing can be programmed). - The microphone can be installed up to 10 km away from the unit. - The microphone (sensor) unit is compact and lightweight (2g). - The microphone's terminal uses telecom fiber, allowing the use of existing fiber networks.
