DH-SD8A840-HNF-PA is an 8MP Starlight IR PTZ AI network camera engineered for long-range surveillance across large open areas — ports, industrial sites, highways, and expansive perimeters. Built on Dahua’s WizMind series with a robust metal housing, this camera delivers exceptional imaging combined with powerful zoom and intelligent tracking.
The DH-SD8A840-HNF-PA captures 3840×2160 resolution through a 1/1.8″ CMOS sensor, paired with a 40x optical zoom lens spanning 5.6mm to 223mm focal length. This gives operators the ability to identify details across vast distances, with a DORI detection range reaching 4,400m and an identify range of 440m. Low-light performance is outstanding, rated at 0.005 lux in color mode and dropping to full 0 lux with the illuminator engaged.
Night vision is a defining strength of the DH-SD8A840-HNF-PA, with 10 IR lights extending illumination distance up to an impressive 500m — among the longest ranges in its class. A Smart Wiper feature automatically senses rain and clears the lens, keeping image quality consistent through adverse weather without manual intervention.
Intelligence capabilities are extensive. The DH-SD8A840-HNF-PA supports Auto Tracking 3.0, which follows detected targets with detailed trajectory mapping, along with full video metadata extraction covering human body, human face, motor vehicle, and non-motor vehicle attributes. Face recognition is built in, supporting face information collection, attribute extraction, face database management, and comparison — making this camera suitable for access monitoring and identity verification at range.
The camera’s IVS (perimeter protection) suite covers tripwire, intrusion, fence climbing, loitering, abandoned/missing object detection, fast-moving object alerts, parking detection, people gathering, and vehicle/human alarm classification, giving comprehensive coverage for large-area threat detection.
PTZ performance is built for serious operational demands, with a full 360° pan range, -30° to +90° tilt with auto-flip, and speeds up to 240°/s pan and 100°/s tilt. The DH-SD8A840-HNF-PA supports 300 presets, 8 tours, 5 patterns, and 5 scan modes, giving operators extensive automation options for continuous area coverage.
Built for harsh environments, the DH-SD8A840-HNF-PA carries IP67 protection along with TVS 6000V lightning and surge resistance, and operates across an extreme -40°C to +70°C temperature range. Power comes via 36VDC Hi-PoE, drawing up to 48W with illuminator, heater, and fan active. Video compression uses Smart H.265+/H.264+ codecs for efficient bandwidth management despite the camera’s high-resolution, long-range capture.
For critical infrastructure, transportation hubs, and large industrial perimeters that demand serious range and intelligence, the DH-SD8A840-HNF-PA delivers professional-grade performance.
