Extra Info
Motorized Vari-Focal Lens – Remote Zoom and Focus Flexibility
Featuring a 2.7–13.5 mm motorized vari-focal lens, this camera allows users to remotely adjust the zoom and focus through an NVR, VMS, or mobile app—no need to physically access the camera. This makes it ideal for hard-to-reach installations such as high ceilings, exterior walls, or large indoor facilities, and offers the versatility to adapt the field of view for wide coverage or zoomed-in detail, depending on the surveillance need.
Starlight Color Performance – Extended Color in Low-Light Conditions
Utilizing Dahua’s Starlight imaging technology, the camera captures vibrant color video in lighting conditions as low as 0.005 Lux. This significantly delays the need to switch to infrared mode, helping operators maintain important visual detail and subject identification well into the night. It’s especially useful in parking lots, alleyways, commercial perimeters, or low-lit entry points.
Smart IR Up to 40 m – Even Illumination, No Overexposure
Equipped with two high-performance infrared LEDs, the camera delivers up to 40 meters of IR night vision. The Smart IR function dynamically adjusts brightness based on object distance to prevent close-up subjects from appearing washed out, ensuring balanced, detailed images throughout the night, whether subjects are near or far.
AI Intrusion Detection – Focused Alerts, Fewer False Positives
This camera supports AI-enhanced Intelligent Video System (IVS) features, such as tripwire and intrusion detection. You can define custom zones and trigger alerts only when humans or vehicles cross these digital boundaries. This significantly reduces false alarms from animals, shadows, or weather changes and is ideal for fenced perimeters, loading docks, school zones, or private driveways.
Secure & Reliable Recording – Backup When It Matters Most
Footage can be recorded directly to a microSD card (up to 256 GB), as well as to NAS, FTP servers, or Dahua Cloud, providing redundant storage options in case of a network outage. This ensures that critical footage is not lost, making it ideal for remote locations or critical infrastructure where network interruptions may occur.
Built Tough – Outdoor-Ready with Vandal and Weather Protection
Housed in a full-metal casing, the camera meets IP67 standards for protection against dust and water ingress, and IK10 rating for resistance to vandalism and physical impact. Whether mounted in a public space, industrial facility, or outdoor wall, it’s designed to withstand rain, wind, tampering, and extreme environments, ensuring long-lasting performance in even the most demanding deployments.
