Dahua PTZ85448-HNF-PA-FL

The Dahua PTZ85448-HNF-PA-FL is a professional 4MP 48× Starlight Laser AI Network Positioning System engineered for ultra-long-range surveillance of borders, ports, airports, industrial facilities, oil and gas sites, utilities, highways and other critical infrastructure. Equipped with a large 1/1.8-inch CMOS sensor, it delivers up to 2560 × 1440 resolution and uses a 6.25–300 mm motorized lens with 48× optical zoom and 16× digital zoom, allowing detailed observation across very large distances. Its powerful laser illumination reaches up to approximately 1,000 metres, while 140 dB WDR, optical defog, electronic image stabilization and Starlight low-light technology support clear imaging in challenging conditions. AI functions include face recognition, video metadata, perimeter protection, human/vehicle classification and intelligent target analysis, together with continuous 360° pan, 300 presets, built-in wiper, two-way audio, MicroSD storage up to 512 GB and an integrated 100 Mbps single-fiber interface capable of transmission up to approximately 20 km. Its rugged IP67 housing, 6 kV lightning protection and –40°C to +70°C operating range make it suitable for demanding outdoor environments. VEGA Digital IT Solutions LLC, as a SIRA-approved CCTV/security solutions provider in Dubai, supplies, integrates and commissions Dahua long-range surveillance systems for projects throughout the UAE. The expanded Dahua positioning-system range provides alternatives for different resolution, zoom and illumination requirements. The PTZ85260-HNF-PA-FL is a 2MP 60× Starlight Laser AI positioning system, using a 1/1.8-inch sensor, up to 1920 × 1080 resolution, approximately 5.6–336 mm lens, exceptionally long 60× optical zoom and up to 1,000 m laser illumination, together with AI perimeter protection, face recognition, video metadata, two-way audio and IP67 construction. The PTZ85848-HNF-PA is the 8MP / 4K 48× Starlight IR WizMind version, delivering up to 3840 × 2160 resolution, 48× optical zoom and approximately 400 m IR illumination, with auto-tracking, perimeter protection and face recognition; this is distinct from the PTZ85848-HNF-PA-FL laser version, which extends illumination to approximately 1,000 m. The PTZ83440-HNR-GA-S is a newer 4MP 40× IR WizMind positioning system with up to 300 m IR, AI gyroscope image stabilization, Smart PT Correction, Auto Tracking 3.0, built-in wiper and IP67 protection, making it suitable where precision positioning and image stability are especially important. The compact PTZ37225-HNP-GB-A-EG provides 2MP resolution, 25× optical zoom, approximately 150 m IR and 50 m white-light illumination, AI Auto Tracking 3.0, perimeter protection and high-precision PT operation, including suitability for applications such as substation inspection and remote industrial monitoring. VEGA Digital can supply and integrate these Dahua positioning systems across the UAE; however, an individual model should only be called “SIRA Approved” when that exact current model/SKU is confirmed in SIRA’s certified-equipment records. Otherwise, it should be described as suitable for SIRA-oriented/SIRA-compliant CCTV solutions, subject to exact-model approval verification. For system installation, VEGA Digital can select the appropriate PTZ85448-HNF-PA-FL, PTZ85260-HNF-PA-FL, PTZ85848-HNF-PA, PTZ83440-HNR-GA-S or PTZ37225-HNP-GB-A-EG according to the required surveillance distance, resolution, optical zoom, night-time coverage, analytics and environmental conditions. These positioning systems can be integrated through professional IP and fiber-optic infrastructure with compatible Dahua NVR, IVSS or DSS video-management platforms, while dedicated power supplies, network switches, fiber interfaces, surge/lightning protection, earthing, UPS backup and surveillance storage are engineered according to the exact camera and site requirements. During commissioning, VEGA Digital can configure PTZ presets and tours, auto-tracking, perimeter protection, human/vehicle classification, face recognition, video metadata, laser/IR/white-light operation, WDR, optical defog, image stabilization, alarm linkage and remote monitoring, while carefully calibrating positioning accuracy and analytics zones. Long-range laser and IR cameras should be mounted on structurally stable poles or walls with an unobstructed field of view and appropriate lightning protection. For Dubai installations, the exact camera model, recorder/VMS, storage, fiber/network architecture, power system, mounting arrangement and retention configuration should be verified against the applicable current SIRA requirements before final deployment, enabling VEGA Digital to deliver a complete Dahua critical-surveillance solution across the UAE.
