Hikvision DS-2CD2186G2H-ISU — 8MP 4K AcuSense Fixed Dome Camera with Built-in Mic & 120dB WDR

Compact and purpose-built for high-definition monitoring, the Hikvision DS-2CD2186G2H-ISU is an 8 MP / 4K fixed dome IP camera suited to houses, retail stores, offices and warehouses, indoors or out. Its 1/1.8" progressive-scan CMOS sensor captures detailed 3840 × 2160 images and holds colour down to 0.0005 lux, while on-board AcuSense deep learning separates humans and vehicles from other movement so alerts stay meaningful. Audio context comes from the built-in microphone, difficult lighting is tamed by 120 dB true WDR and 3D DNR, and H.265+ encoding keeps storage and bandwidth demands low. The tough IP67 / IK10 enclosure comes in white or black, with either a 2.8 mm or 4 mm fixed lens. Australian stock, 3-year Australian warranty.

4K Clarity with Smart AI Detection

8 MP / 4K Resolution

At 3840 × 2160, the 4K sensor resolves fine detail across a broad scene and leaves enough headroom to zoom into recorded footage and still make out a face or read a label — well suited to shops, offices, warehouses and residential perimeters.

AcuSense Human & Vehicle AI

Deep-learning AcuSense analysis decides whether movement came from a human or a vehicle, cutting out the nuisance triggers caused by animals, moving foliage and weather so that motion recording and notifications can be trusted.

Excellent Low-Light + 120 dB WDR

The generous 1/1.8" sensor performs strongly after dark, retaining colour to 0.0005 lux, and 120 dB true WDR plus 3D DNR keep harshly backlit and grainy scenes readable.

Built-in Mic, White or Black

The built-in microphone layers audio over your video evidence, and the hard-wearing IP67 / IK10 dome can be ordered in white or black with a 2.8 mm or 4 mm lens so it suits both the scene and the building.

Frequently Asked Questions

Which lens should I choose, 2.8 mm or 4 mm?

Go with 2.8 mm when you want the broadest field of view — front doors, shopfronts and whole-room coverage. Pick 4 mm when the view can be a little tighter in exchange for extra reach, such as identifying detail at the end of a corridor or driveway.

What does AcuSense do?

AcuSense runs deep learning on the camera itself to label movement as a human or a vehicle, screening out false triggers from animals, foliage and weather so alerts are smarter and more dependable.

Does it record audio?

It does — the -ISU model includes a built-in microphone, so sound is captured alongside the video and adds useful context in both live view and playback.

Is it suitable for outdoor use?

Yes. This dome carries an IP67 weatherproof rating and IK10 vandal resistance, and works across a -30 °C to +60 °C range, making it fine for indoor rooms as well as fully exposed outdoor positions.
