DS-QFV0502 - 5Km Dual-Channel Distributed Vibration Fiber-Optic Sensing Server

The Hikvision DS-QFV0502 is a high-performance, 2-channel Distributed Acoustic Sensing (DAS) fiber-optic server engineered for long-range perimeter security and intrusion monitoring up to a 5 km detection distance per channel. Operating on a frequency response range of 10 Hz to 5 kHz, it simultaneously tracks and maps multiple vibration points with a high positioning accuracy of ± 5 m and an ultra-fast alarm response time of ≤ 2 s. Driven by integrated Hikvision deep-learning algorithms, the system intelligently classifies and reports specific intrusion signatures—including climbing, fence-crossing, and ground excavation—providing automated logs detailing alarm type, timestamp, geographic latitude/longitude, and severity level. Because it attaches to passive fiber lines, the system requires no field power supplies and adapts smoothly to complex terrains, maintaining stable tracking despite moisture, extreme temperature variations, ammonia, chlorine, salt spray, or acid rain.
