Product SKU: DS-2CD3667G3-LIZSU(Y)
Product Overview
The Hikvision DS-2CD3667G3-LIZSU(Y) is a premium 6 MP ColourVu varifocal bullet network camera, designed for outstanding low-light performance and intelligent threat detection. Equipped with a 2.8–12 mm motorised varifocal lens, it delivers flexible coverage from wide-area monitoring to detailed close-ups.
Why Choose the DS-2CD3667G3-LIZSU(Y)
This camera harnesses Hikvision’s advanced ColourVu technology for vivid full-colour images 24/7 and features Smart Hybrid Light which intelligently switches between white light and infrared modes—ensuring optimal visibility up to 60 metres in darkness. With built-in AcuSense deep-learning algorithms, it classifies human and vehicle targets, significantly reducing false alarms, and integrates active strobe-light and audio-alarm functions for immediate deterrence.
Key Capabilities
Flexible coverage via 2.8–12 mm varifocal lens: The lens range allows installers to adjust focus post-installation, providing adaptability for diverse applications—from wide car park surveillance to closer entry monitoring.
Full-colour imaging in low light: ColourVu technology, paired with a large-aperture lens and smart lighting, ensures vivid colour capture even under very low illumination, enhancing identification and visual clarity.
Smart Hybrid Illumination (IR + white light): Automatically switches lighting modes up to 60 m, combining IR for covert surveillance and white light for clear colour when events are triggered—improving detection and deterrence.
AI-powered human & vehicle classification: Built-in AcuSense analytics enable the camera to distinguish between human and vehicle targets and filter irrelevant motion, reducing false alarms and enhancing response accuracy.
Active deterrence capability: Integrated strobe light and audio alarm provide immediate visual and audible warnings when a security event is detected, helping to thwart intrusion attempts in real time.
Rugged outdoor build: IP67 weather-proof and IK10 vandal-resistant housing (plus optional anti-corrosion “-Y” design) ensures reliability in harsh outdoor environments and coastal installations.
