Extra Info
Vari-Focal Lens (2.7–13.5 mm) – Precision View Control at Your Fingertips
Equipped with a motorized 2.7–13.5 mm vari-focal lens, this camera allows for remote adjustment of zoom and focus through platforms like Smart PSS, NVR interfaces, or mobile apps. The lens supports a wide 104° field of view for general surveillance and narrows down to 27° for detailed monitoring of distant objects. This flexibility is perfect for multi-purpose areas, corridors, or entrances, where monitoring needs may change over time.
Starlight for Low Light – Color Vision in the Dark
With 0.008 Lux sensitivity, Dahua’s Starlight technology enables the camera to maintain color video in extremely low-light environments. This provides longer-lasting detail before switching to infrared mode, improving identification and clarity in dimly lit areas like back alleys, warehouses, or underpasses.
AI IVS Detection – Smarter Motion Alerts
Advanced AI-powered Intelligent Video System (IVS) features include tripwire and intrusion detection that allow you to define custom virtual zones. These features are designed to only trigger when human or vehicle activity is detected, minimizing false alerts from wind, rain, or random movement—perfect for private driveways, fences, or sensitive entryways.
Smart IR up to 40 m – Balanced Illumination at Night
Two built-in high-efficiency IR LEDs provide up to 40 meters of infrared night vision. The Smart IR feature automatically adjusts brightness based on subject distance, ensuring that objects close to the camera don’t get overexposed and washed out. Ideal for narrow paths, residential driveways, and building entrances where lighting balance is crucial.
Reliable Local Recording – Secure Footage Without a Network
The camera supports onboard storage via a microSD card (up to 256 GB), providing reliable backup recording even if the network goes down. This makes it an excellent choice for standalone installations, off-grid locations, or as a redundant recording method to complement cloud or NVR systems.
Tough Outdoor Design – Built to Endure the Elements
Housed in a durable eyeball-style dome, the camera boasts an IP67 weatherproof rating, protecting it from dust, rain, and extreme weather. It’s purpose-built for outdoor use on walls, ceilings, eaves, or other exposed locations where rugged reliability is required.
