Product SKU: DS-2CD2T66G2H-4I
Product Overview
The Hikvision DS-2CD2T66G2H-4I is a professional 6 MP bullet-style hybrid camera combining advanced ColorVu warm-light illumination with powerful infrared (IR) capability for 24/7 full-colour imaging. Replacing the older DS-2CD2T66G2 model, this upgraded version provides superior brightness, extended IR range up to 80 m, and AcuSense technology for intelligent human and vehicle detection. It’s ideal for outdoor installations requiring dependable surveillance and precise colour reproduction at long distances.
Why Choose the DS-2CD2T66G2H-4I
The DS-2CD2T66G2H-4I is built for accuracy, flexibility, and resilience. Its hybrid ColorVu + IR system ensures vivid colour footage in low light while automatically switching to IR in complete darkness. With up to 80 m IR range, 6 MP resolution, and 120 dB True WDR, it delivers detailed imaging in all conditions. H.265+ compression reduces storage costs, and the robust IP67-rated housing ensures long-term reliability in harsh Australian weather.
