Dahua DH-IPC-HFW3667E-AS-IL-ANZ — 6MP Smart Dual Light Bullet, White or Black

Smart Dual Light is Dahua's answer to an old compromise: infrared gives you range but only in monochrome, while white light gives you colour but runs all night and annoys the neighbours. This camera carries both and switches intelligently — it sits quietly in infrared until its AI recognises a person or vehicle, then brings up the warm light to capture the moment in full colour. You get discreet monitoring most of the night and colour evidence exactly when it counts. Available in white or black to suit the building.

Core Technology

• Smart Dual Light Switching — Runs on infrared by default and hands over to warm light only when AI detects a person or vehicle, so you get colour evidence without a floodlight burning all night.
• 6MP at 3288 x 1850 — Half again the detail of a 4MP camera, with both IR and warm light reaching 30 m.
• Down to 0.0005 Lux — An F1.4 aperture and 3D noise reduction keep the picture usable in near-total darkness before any illuminator is needed.
• Published DORI Figures — Dahua rates the 2.8 mm lens at 84.8 m detect and 17.0 m recognise, so you can design coverage from real numbers instead of guesswork.
• WizSense 3 with AcuPick — Human and vehicle classification on perimeter rules, plus AI scene self-adaptation that retunes the image as conditions change.
• White or Black Finish — Choose the variant that disappears into your eaves, soffit or dark render rather than advertising itself.

Where It Fits

An excellent all-round exterior camera and our pick where a warm light would otherwise be a nuisance — homes with close neighbours, apartment blocks, and hospitality venues where a permanent floodlight would spoil the room.
