Hikvision DS-2CD2166G2-I 6MP AcuSense Dome IP Camera with IR Night Vision
The Hikvision DS-2CD2166G2-I is a professional-grade 6 MP network dome camera featuring AcuSense AI technology for intelligent human and vehicle detection. Powered by DarkFighter low-light technology, this camera delivers exceptional image quality with 3200 × 1800 resolution, accurate target classification, and up to 30 m infrared night vision. Built for demanding outdoor environments, it features IP67 weatherproof and IK10 vandal-resistant housing.
AcuSense AI Technology
Empowered by deep learning algorithms, Hikvision AcuSense technology classifies human and vehicle targets, significantly reducing false alarms caused by animals, foliage, or environmental changes. The system focuses on genuine security threats, improving alarm efficiency and response times for residential and commercial installations.
-
Human and Vehicle Classification: Deep learning algorithms distinguish between people, vehicles, and other moving objects
-
Smart Event Detection: Line crossing, intrusion, region entrance, and region exit detection with target-specific triggering
-
Reduced False Alarms: Filters out non-threat motion for more reliable security alerts
Powered-by-DarkFighter Low-Light Performance
With powered-by-DarkFighter technology, the DS-2CD2166G2-I delivers excellent low-light imaging performance. Colour imaging is available down to 0.003 lux, ensuring clear, detailed footage even in challenging lighting conditions. The 120 dB true WDR technology provides clear imaging against strong backlight.
-
Low-Light Sensitivity: 0.003 lux colour imaging with F1.6 aperture
-
IR Night Vision: Up to 30 m infrared range with smart IR adjustment
-
120 dB True WDR: Clear imaging in high-contrast scenes with strong backlight
High-Resolution Imaging
The 1/2.4" progressive scan CMOS sensor captures sharp 6 MP resolution video at 3200 × 1800, providing exceptional detail for identification and forensic analysis. H.265+ compression reduces bandwidth and storage requirements without compromising image quality.
Rugged Construction
Designed for harsh outdoor environments, the DS-2CD2166G2-I features IP67 weather protection against dust and water ingress, and IK10 vandal resistance for protection against physical impacts. The camera operates reliably in temperatures from -30°C to 60°C.
