Product SKU: DS-2CD3666G2HT-LIZS(Y)
Product Overview
The DS-2CD3666G2HT-LIZS(Y) from Hikvision is a 6 MP ultra-series smart hybrid bullet network camera designed to deliver high-resolution imaging and advanced analytics for demanding security applications. With a motorised varifocal 2.7–13.5 mm lens and long-range smart illumination up to 60 m, it offers exceptional clarity in both day and night settings. Featuring the industry-leading DarkFighter S technology for low-light, plus deep-learning-based human & vehicle classification, this camera is purpose-built for professional surveillance installations where reliability, intelligence and performance matter.
Why Choose the DS-2CD3666G2HT-LIZS(Y)
Choosing the DS-2CD3666G2HT-LIZS(Y) means investing in a camera that not only captures crisp 6 MP (3200 × 1800) resolution images but also intelligently filters activity with deep-learning analytics to reduce false alarms and improve actionable outcomes. Its motorised 2.7–13.5 mm lens enables precise zoom and framing after installation, offering flexibility across different environments. The combination of DarkFighter S low-light performance, 120 dB wide dynamic range (WDR), and Smart Hybrid Light ensures reliable performance across high-contrast and challenging lighting scenarios. Built for harsh outdoor use with IP67/IP NEMA 4X (-Y) and IK10 vandal protection, it stands out for durability and smart detection—offering superior value compared to standard bullet cameras lacking hybrid lighting or AI-powered analytics.
Key Capabilities
High-Resolution Imaging: With a maximum resolution of 3200 × 1800 (6 MP), the DS-2CD3666G2HT-LIZS(Y) delivers sharp, detailed footage that enhances identification and forensic clarity in both live and recorded video.
Motorised Varifocal Lens (2.7–13.5 mm): The motorised lens allows remote adjustment of zoom and focus, enabling installers and integrators to optimise field of view and framing post-installation—minimising ladder time and fine-tuning coverage.
Deep-Learning Human & Vehicle Classification: Built-in AI enables the camera to distinguish human and vehicle targets, improving alarm accuracy by reducing false triggers from irrelevant motion—so you get alerts you can trust.
Smart Hybrid Illumination (Up to 60 m): Features both IR and white-light illumination up to 60 metres, automatically switching to ensure clear colour and monochrome images depending on the scene—ideal for high-security entrances or perimeter zones.
Rugged Outdoor Build with IP67/NEMA 4X and IK10: Constructed with a metal front cover, body and bracket, it’s rated IP67 and IK10 (and NEMA 4X for the “-Y” variant) to withstand harsh weather, vandalism and corrosion—perfect for external installations in Australia’s varied climate.
Key Features
-
6 MP Sensor with DarkFighter S Technology: A large 1/1.8″ CMOS sensor delivers excellent image detail and low-light performance, enabling colour or monochrome viewing even in very dim environments.
-
120 dB Wide Dynamic Range (WDR): Ensures clear visibility in scenes with strong contrasts, such as entrances or backlit windows, by balancing extreme light and shadow.
-
Efficient H.265+/H.265 Compression: Supports advanced codec standards to reduce bandwidth and storage usage while maintaining high-quality video—ideal for network efficiency.
-
Built-in HEOP (Hikvision Embedded Open Platform): With 1.5 TOPS computing power, 40 MB open resources, 350 MB smart RAM and 2 GB eMMC storage, the camera supports third-party applications, enabling customisation and integration into complex systems.
