Product Overview
For installations where ceiling or eave-mounted coverage needs to combine discreet profile with serious imaging capability, the DS-2CD2186G2H-ISU-BLK delivers 8MP 4K resolution from a compact vandal dome housing finished in black. Built around a 1/1.8-inch progressive-scan CMOS sensor, it uses Hikvision DarkFighter technology to maintain colour imaging down to 0.0008 Lux at F1.0, making it highly capable in low ambient light before the 30m smart IR illuminator takes over. AcuSense deep-learning classification filters motion events down to human and vehicle targets, reducing event noise across busy sites. The IK10-rated housing handles physical impact alongside IP67 weather sealing, so this dome camera suits both interior spaces and exposed outdoor positions. A built-in microphone enables onsite audio capture, and the microSD slot supports up to 512GB of edge storage for standalone or backup recording scenarios.
Key Capabilities
8MP 4K Imaging on a 1/1.8-Inch Sensor
The larger-than-standard 1/1.8-inch sensor captures 3840 x 2160 resolution with improved light collection, giving clearer subject detail at entrances, corridors, and car parks where identifying individuals or reading signage matters.
DarkFighter Low-Light Colour Performance
Colour imaging is maintained down to 0.0008 Lux at F1.0, covering dusk, dawn, and dim interior conditions without immediately switching to black-and-white IR mode. This is particularly useful in entry lobbies and covered car parks with partial lighting.
AcuSense Human and Vehicle Classification
Deep-learning algorithms classify detected motion as human or vehicle targets, filtering out triggers from wind-blown foliage, small animals, and lighting shifts. This cuts down event volume on busy sites and makes footage review far more targeted.
IP67 and IK10 Dome Housing in Black
Fully sealed against dust and rain to IP67, with IK10 impact resistance rated to 20 joules, this dome housing suits outdoor soffits, semi-exposed walkways, and vandal-prone wall positions. The black finish suits dark fascias and commercial exteriors.
Built-In Microphone and Edge Storage
A built-in microphone captures onsite audio alongside video, adding context to recorded events. The microSD slot accepts cards up to 512GB, enabling standalone edge recording or backup storage without requiring a separate NVR for every installation point.
Best For
- Building Entrances and Lobby Ceilings: The 2.8mm lens provides a 105-degree horizontal field of view, covering wide entry points from a ceiling-mounted position while the 4K sensor captures enough detail for subject identification.
- Outdoor Soffits and Covered Walkways: IP67 and IK10 ratings mean the black dome housing handles rain, dust, and physical interference in semi-exposed positions that standard indoor domes cannot tolerate.
- Retail and Commercial Car Parks: DarkFighter colour performance and 30m IR range cover low-light car park environments across dusk-to-dawn periods, and AcuSense filters vehicle and pedestrian events reliably.
- Sites Requiring Edge or Backup Recording: The 512GB microSD slot supports standalone recording at remote positions or as a failover layer alongside NVR-based infrastructure.
Why Choose the DS-2CD2186G2H-ISU-BLK
The DS-2CD2186G2H-ISU-BLK sits above entry-level 4K domes in several measurable ways. The 1/1.8-inch sensor is larger than typical 4K CMOS sensors, which directly improves low-light performance before DarkFighter processing is even factored in. The 130dB true WDR handles simultaneous bright and dark zones in the same frame, which is a common problem at doorways and lobby windows. AcuSense human and vehicle classification is a genuine reduction in event noise, not just pixel-based motion detection. The black finish suits commercial fascias, dark ceilings, and architectural environments where a white dome would be visually inconsistent. Alarm I/O support enables integration with external devices such as sirens or access control triggers. Available through Security Wholesalers, the DS-2CD2186G2H-ISU-BLK is a well-specified vandal dome for installations that need 4K detail, low-light colour performance, and reliable analytics in a single housing.
Buyer Decision Tips
Lens Choice for This SKU: The DS-2CD2186G2H-ISU-BLK is supplied with a fixed 2.8mm lens, giving a horizontal field of view of approximately 105 degrees. This is well suited to wide ceiling coverage at entrances, corridors, and open floor areas. If your installation calls for a tighter view to cover a longer approach or a narrow lane, a 4mm fixed-lens variant provides a 90-degree horizontal field of view with greater working distance before object detail degrades. Confirm your mounting height and target distance before selecting the lens focal length.

Ideal Use Cases
Building Entry Points
Ceiling-mounted at doorways and foyers, the 2.8mm lens covers the full width of standard entry openings. The 130dB WDR manages backlit conditions from glass doors or windows without washing out subject faces.
Outdoor Walkways and Covered Car Parks
IP67 sealing and IK10 impact rating make this dome suitable for soffits, stairwells, and covered car park ceilings where weather exposure and the risk of tampering are both present.
Retail Shopfronts and Back-of-House
The black dome housing blends into dark ceilings and commercial fitouts. AcuSense classification flags human activity in staff-only areas or after-hours at shopfronts without triggering on environmental motion.
School and Campus Perimeters
4K resolution and a 30m IR range cover external corridors and building perimeters through the evening hours. AcuSense human detection helps site managers respond to out-of-hours activity on campus grounds.
Remote or Stand-Alone Positions
The 512GB microSD slot allows this camera to record locally at gates, outbuildings, or remote access points where running NVR cabling is impractical. PoE simplifies power delivery from a single Cat5e or Cat6 run.
Choosing the Right Model
- Choose this model if: You need 4K ceiling-mounted dome coverage with DarkFighter low-light colour performance, AcuSense human and vehicle analytics, IK10 vandal resistance, a built-in microphone, and a black finish to match dark-toned commercial fitouts or building exteriors.
- Choose a different model if: Your installation requires a wider adjustable field of view or the ability to re-aim the camera after mounting without physically repositioning the base. In that case, a motorised varifocal dome or a turret-style camera with a repositionable head would give more post-installation flexibility. If the white finish is preferred to match light-coloured ceilings, the standard (non-BLK) variant of this same model series is the appropriate choice.
FAQs
- What does the -BLK suffix mean for the DS-2CD2186G2H-ISU-BLK?
The -BLK suffix designates the black housing variant of this dome camera. The camera body, dome cover, and trim ring are all finished in black, making it suited to dark ceilings, charcoal fascias, and commercial environments where a white camera would stand out. The imaging specifications, lens, IR range, and protection ratings are identical to the standard white-finish version.
- Is the 2.8mm lens fixed or can it be adjusted after installation?
The lens is fixed at 2.8mm and cannot be adjusted or swapped. This gives a horizontal field of view of approximately 105 degrees, which suits wide ceiling coverage at entrances, corridors, and open areas. If your site requires a tighter angle to cover a longer approach or a specific narrow zone, a 4mm fixed-lens variant provides a 90-degree horizontal field of view with greater effective working distance.
- How does AcuSense classification differ from standard motion detection?
Standard pixel-based motion detection triggers on any change in the frame, including moving shadows, passing headlights, swaying vegetation, and animals. AcuSense uses deep-learning models trained on human and vehicle shapes to classify whether a detected object matches those targets. Events that do not match are filtered out before an alert is generated, which significantly reduces the volume of non-relevant notifications on active sites.
- Can the built-in microphone be used for two-way communication?
No. The DS-2CD2186G2H-ISU-BLK includes a built-in microphone for one-directional audio capture, meaning audio is recorded alongside video. There is no built-in speaker confirmed in this camera. Two-way communication is not supported natively by this unit. The audio input captures ambient sound and conversation near the camera for recording and review purposes.
- Does the IK10 rating make this camera suitable for high-risk vandal-prone areas?
IK10 is the highest impact resistance classification under EN 62262, rated to withstand 20 joules of impact, equivalent to a 5kg mass dropped from 400mm. Combined with IP67 dust and water ingress protection and an operating temperature range of -30 to +60 degrees Celsius, this dome housing is suited to exposed outdoor positions, stairwells, car parks, and public-access areas where attempted tampering is a realistic concern.
- Where can I access the datasheet and is this camera available locally?
The official Hikvision DS-2CD2186G2H-ISU datasheet is linked in the Additional Information section below and covers full technical specifications including DORI distances, power consumption, and supported protocols. The DS-2CD2186G2H-ISU-BLK is part of the Security Wholesalers range and is stocked locally in Australia, supporting faster delivery compared to ordering direct from overseas distributors.
