Extra Info
Motorized Vari-Focal Zoom (2.7–13.5 mm) – Remote Zoom Control for Flexible Viewing
This camera features a motorized vari-focal lens that can be adjusted remotely, offering a wide range of views from 113° (wide) to 31° (narrow). Whether you need broad coverage of an area or focused monitoring of a specific point, this feature allows fine-tuning of the field of view without manual adjustment—ideal for multi-purpose sites, elevated installations, or post-deployment tweaking.
Starlight Technology for Night Color – Low-Light Imaging with Enhanced Detail
Dahua’s advanced Starlight technology enables the camera to capture color video down to 0.008 Lux, far outperforming traditional low-light sensors. This allows the system to provide clear, detailed images at night without immediately switching to IR, ensuring better subject recognition, evidence capture, and scene awareness during dusk, dawn, or poorly lit environments.
Smart IR up to 40 m – Night Vision That Adapts
Equipped with infrared LEDs and Smart IR technology, this camera delivers night vision up to 40 meters, automatically adjusting IR brightness to suit the subject's distance. This ensures even exposure across the frame, preventing nearby objects from being overexposed while still capturing activity in the background — making it ideal for driveways, entrances, or perimeter walls.
Advanced AI Detection (IVS) – Intelligent Video Analytics for Targeted Alerts
Built-in Intelligent Video System (IVS) allows you to set tripwire lines and intrusion zones that trigger only when humans or vehicles enter designated areas. This reduces false alarms caused by weather, animals, or shifting shadows, allowing for more reliable monitoring and faster threat recognition in sensitive areas like gated entries, loading bays, or school zones.
Tough Metal Design + IP67 – Rugged Build for Outdoor Reliability
Housed in a full-metal enclosure, this camera meets IP67 certification for protection against dust, rain, and harsh weather. Its rugged construction is ideal for exterior mounting on walls, ceilings, poles, or gateposts, where it may be exposed to the elements. Built for long-term outdoor use, it offers dependable surveillance in industrial sites, parking lots, and residential areas.
