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 is undetectable by detection devices (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 is made of telecom fiber, allowing the use of existing fiber networks.
