Dahua SD49225DB-HC 2MP 25x Starlight IR HDCVI PTZ Camera

The Dahua SD49225DB-HC represents professional-grade surveillance technology engineered for demanding security applications. Built around a 1/2.8" 2MP STARVIS™ CMOS sensor, this PTZ camera delivers exceptional low-light performance with a minimum illumination of just 0.005 lux in color mode and 0.0005 lux in black and white, complemented by 100-meter infrared illumination for complete 24/7 coverage. The 25× optical zoom lens (4.8–120mm) provides remarkable versatility, enabling operators to detect subjects at distances exceeding 1.6 kilometers while maintaining precise focus control through auto, semi-auto, and manual modes. Advanced imaging features include 120dB true wide dynamic range, 3D noise reduction, and electronic defog to ensure clarity across varying environmental conditions. Mechanical performance meets industrial standards with endless 360° pan rotation, –15° to +90° tilt range with auto-flip capability, and preset speeds reaching 240°/s pan and 200°/s tilt. The camera supports 300 presets, 8 programmable tours with up to 32 presets each, and 5 scan patterns for flexible surveillance strategies. Robust construction ensures reliability in harsh environments—IP66-rated housing, operating temperature range of –40°C to +70°C, TVS 6000V lightning protection, and surge suppression. Multiple output formats (CVI, TVI, CVBS, AHD) provide seamless integration with existing systems, while dual alarm inputs and one alarm output enable intelligent event-driven responses. Power consumption remains efficient at 10W basic operation, scaling to 22W maximum with all features active.
