Common questions
How does it compare with the 2MP 25x model?
This model records 4MP (2560 × 1440) on a 5mm-125mm lens, against 2MP (1920 × 1080) on a 4.8mm-120mm lens for the DH-SD49225DB-HNY. Dahua's Identify distance is 250m here against 161m.
Does it detect people and vehicles automatically?
Yes. Perimeter protection filters out false alarms from animals, rustling leaves and bright lights, and classifies humans and vehicles. As a motion detection camera it also lists SMD 4.0 (Smart Motion Detection) and face detection.
Is it a WizSense camera?
Yes. Dahua lists it in its WizSense series, and as an AI camera it focuses on humans and vehicles. See our guide to Dahua WizSense cameras.
How far can it see at night?
As an infrared camera, its IR illumination reaches up to 100m, and Starlight technology gives colour images down to 0.005 lux. See our Starlight guide.
How is it powered?
12VDC 3A (±10%) or PoE+ (802.3at). Power use is 9W basic and up to 20W with illuminator, alarm and PTZ running. A PoE+ capable NVR can power and record it over one cable.
Is it suitable for outdoor use?
Yes. It is IP66 rated with TVS 6000V lightning, surge and voltage transient protection, and works from -40°C to +70°C.
