Our Distributed Acoustic Sensor(DAS) with excellent pattern recognition software can detect and locate the distributed thousanfs of acoustic events. Whenever any vibration or sound around its sensing fiber is detected, our DAS system will process the measured data in real-time and its pattern recognition software will recognize the types of the events, such as digging, pipeline leakage, fence breach, vehicle moving person walking. And, the detected events are reported to the alarm server to help operators take actions to protect theor facilities.
