DS-QFV5002 - 50KM Dual Channel Distributed Vibration Fiber-Optic Sensing Server

The Hikvision DS-QFV5002 is an ultra-long-range, 2-channel Distributed Acoustic Sensing (DAS) fiber-optic server engineered for massive-scale perimeter security and intrusion tracking up to a 50 km detection distance per channel. Operating across a wide frequency response range of 0.1 Hz to 5 kHz, it simultaneously monitors and maps multiple independent vibration points with a positioning accuracy of ± 5 m and an ultra-fast alarm response time of ≤ 1 s. Powered by integrated Hikvision algorithms, the system intelligently classifies and reports specific intrusion activities—including climbing, fence-crossing, and excavation—providing automated data detailing the alarm type, timestamp, geographic latitude/longitude, and severity level. Utilizing passive fiber lines that require zero field power supplies, it adapts seamlessly to complex terrains and maintains stable tracking despite moisture, extreme temperature variations, ammonia, chlorine, salt spray, or acid rain.
