Dahua DH-SD4D425MB-HNR - 4MP 2K Smart Dual Light WizSense AI PTZ IP CCTV Camera
The Dahua DH-SD4D425MB-HNR is a 4MP 2K Smart Dual Light WizSense AI PTZ IP CCTV camera with 25x optical zoom. IR and warm light illumination each reach up to 100 m, so the camera can switch to full colour video when a target appears. It is an outdoor camera with an IP67 housing and works as a pan tilt zoom camera, panning endlessly through 0° to 360° and tilting from -15° to +90°. As an infrared camera its IR illumination reaches up to 100 m, and with Starlight technology (0.005 lux minimum illumination in colour) it also works as a low light camera. Dahua names it the "4MP 25x Smart Dual Light WizSense Network PTZ Camera".
Key features
- 1/2.8" 4MP CMOS sensor, up to 2560 × 1440 at 25/30 fps, with Starlight technology.
- 25x optical zoom (5 mm to 125 mm).
- Smart Dual Light: the IR illuminator is normally on at night; when a target appears the white light switches on and the camera records full colour video, which reduces light pollution.
- IR distance up to 100 m and warm light distance up to 100 m.
- WizTracking and auto tracking, with AcuPick deep-learning search for people and motor vehicles.
- SMD 4.0 filters out targets that are not a concern, such as small and large animals; perimeter protection (IVS) and face detection with 6 attributes and 8 expressions.
- IP67 housing with TVS 6000 V lightning, surge and voltage transient protection, rated -40°C to +70°C.
- PoE (802.3at) or 12 VDC 3 A; the power adapter is optional.

Common questions
What is Smart Dual Light?
Dahua Smart Dual Light uses an algorithm to detect targets. The IR illuminator is normally on at night; when a target appears in the monitoring area the white light switches on and the camera records full colour video. When the target leaves, the white light goes off and the IR comes back on. Our Smart Dual Light guide explains it in more detail.
What does WizSense mean on the SD4D425MB-HNR?
Dahua lists this camera in its WizSense series, a range of AI products that use an independent AI chip and deep-learning algorithms and focus on humans and vehicles. Our WizSense guide explains the range.
Does it have Starlight low light imaging?
Yes. Dahua lists Starlight technology, with 0.005 lux minimum illumination in colour and 0.0005 lux in black and white. Our Starlight guide explains what Starlight means.
Can it track a moving target automatically?
Yes. Dahua lists auto tracking, where the camera controls pan, tilt and zoom to follow an object in motion, triggered manually or by defined rules. It also lists AcuPick, which uses deep-learning algorithms to match targets such as people and motor vehicles and search live and recorded video.
How is it powered?
It supports PoE (802.3at) or a 12 VDC 3 A supply. The power adapter is listed by Dahua as optional, so it is not included. Power use is basic 8 W and maximum 20 W on DC, or basic 11 W and maximum 23 W on PoE.
Is it suitable for outdoor use?
Yes. As an outdoor PTZ camera it has an IP67 rating with TVS 6000 V lightning, surge and voltage transient protection, and Dahua lists an operating range of -40°C to +70°C.
