## Long description

The DAHUA SD4D825MB-HNR Turret is an outdoor IP security camera that delivers 4K (3840×2160) video at 30 fps using a 1/2.8" CMOS sensor and STARVIS starlight technology. It combines a 25× optical zoom with a wide 86.8° horizontal field of view, 180° rotation range and precise pan/tilt/zoom control for extended-area monitoring. The camera supports wired Ethernet connectivity, ceiling or wall mounting, and is built to operate in harsh outdoor environments with IP67 protection and lightning/surge safeguards. Low-light sensitivity down to 0.005 lx, Smart Dual Light illumination and AI features such as human/vehicle classification, face detection and intelligent video system functions enable reliable perimeter and long-distance surveillance.
Advantages
The camera provides high-resolution 4K imagery combined with a long-range 25× optical zoom for capturing distant details while keeping wide-area coverage. Smart Dual Light and AI-ISP processing produce clearer, color-rich images in low-light and night conditions, reducing dependence on visible lighting. Built-in AI functions — including human/vehicle detection, SMD 4.0 motion classification, face analytics and auto-tracking — reduce false alarms and simplify target identification. Robust mechanical and electrical protection (IP67, surge and lightning protection) ensures continuous operation in outdoor installations.
Suitable for
Perimeter and fence line monitoring
Parking lots and vehicle access control
Large outdoor areas such as campuses and industrial sites
Entrance monitoring with face detection and event capture

How to use
Install the camera on a sturdy ceiling or wall bracket at a height and angle that provide unobstructed coverage of the target area. Connect the unit to a PoE-capable network switch or use a suitable power and Ethernet configuration according to site requirements. Configure camera settings via the Dahua management software or web interface: set resolution and frame rate to 4K/30 fps as needed, adjust zoom and preset patrol positions, and enable AI functions such as human/vehicle detection, face detection and SMD 4.0. Calibrate Smart Dual Light thresholds and auto-tracking rules to match the environment, and define IVS rules (tripwire, intrusion) for automated event triggering and recording.
Usage recommendations
For reliable long-distance surveillance, mount the camera where the 25× optical zoom has clear sightlines and minimize nearby reflective surfaces that can affect IR and white-light performance. Use PoE for simplified installation and ensure surge protection on external network and power lines. Regularly review and tune AI detection sensitivity and snapshot settings to balance detection accuracy and false alarm reduction for your specific site conditions.
