Hikvision DS-2CD2167G2-SU 6MP Gen2 Outdoor ColorVu Dome Camera with Acusense 30m White LED 2.8mm with MIC

Model: DS-2CD2167G2-SU

Who This Is For

When full-colour night imaging and accurate AI detection matter more than anything else in an outdoor dome install, the DS-2CD2167G2-SU is the model to specify. This is a 6MP second-generation ColorVu dome built for outdoor positions where standard IR falls short - carparks, building perimeters, entry points, and retail forecourts where identifying clothing colour, vehicle colour, or plate surrounds at night makes a real difference to incident investigation. The 2.8mm fixed lens suits wide-angle coverage at moderate distances, and the AcuSense deep learning classification cuts out the false motion alerts that plague standard PIR-triggered systems. The built-in microphone adds an audio record to every clip. Installers specifying a clean dome profile that delivers colour imagery down to 0.0005 Lux - without relying on infrared - will find this camera fits that brief directly.

What This Camera Actually Does

Who Buys This Model

• Retail and hospitality operators: Carparks, rear laneways, and loading areas where colour detail on clothing and vehicles is required at night without the washed-out look of IR imaging.
• Property managers and strata committees: Building entrances, pedestrian paths, and bin enclosures where a clean dome profile is preferred and AcuSense alert filtering reduces nuisance notifications to residents.
• Small business owners upgrading from 2MP IR systems: Wanting colour night footage and AI classification on an existing Hikvision NVR without moving to a more complex or expensive camera category.
• Security installers on school and childcare sites: Where IP67 durability, a wide 2.8mm view of outdoor play areas, and audio recording via the built-in microphone are all specified together.
• Installers specifying mixed indoor-outdoor systems: The dome form factor matches indoor ceiling cameras on the same job, keeping the visual footprint consistent across a full site install.

Honest Assessment

The DS-2CD2167G2-SU delivers where it matters most for outdoor colour surveillance: the combination of second-generation AcuSense classification and ColorVu imaging at 0.0005 Lux is genuinely useful, not a spec-sheet claim. The 130 dB WDR handles high-contrast entry point scenarios well, and 6MP at 3072 x 2048 gives meaningful digital zoom headroom during playback. H.265+ compression keeps storage and bandwidth demands manageable on a multi-camera NVR. The built-in microphone adds audio without extra hardware. Where this camera has limits: the 2.8mm fixed lens is wide, so for long-distance identification beyond 17m recognition range, a tighter lens or a different model is the right call. The white LED illuminates to 30m but is visible at night - sites needing covert illumination require an IR model instead. There is no built-in speaker, so this is audio-in only. Available through Security Australia as part of the Hikvision Gen2 range.

Before You Buy

Quick Fit Check

• Good match if: You need full-colour video at night within a 30m range and AcuSense alert filtering on a Hikvision NVR - this camera is purpose-built for exactly that combination.
• Good match if: Your install requires wide-angle outdoor coverage at 6MP with a built-in microphone for audio recording alongside video, and IP67 durability for year-round outdoor exposure.
• You may need a different model if: Your critical monitoring distance exceeds 17m for recognition or you need covert IR illumination - a bullet or dome camera with a longer focal length and infrared LED will serve that scenario better.

Real-World Scenarios

How It Compares

• Choose this if: You need colour night imaging, AcuSense human and vehicle classification, and a built-in microphone in a single outdoor dome at 6MP - this camera delivers all three confirmed in one unit.
• You may need a different model if: Your primary requirement is long-distance recognition beyond 17m, covert IR illumination, or optical zoom - a bullet or varifocal dome camera is more suitable for those scenarios.
• Pairs well with: A Hikvision AcuSense NVR with H.265+ decoding - the AI classification events are handled and stored natively, and alert filtering is managed at the recorder level rather than requiring separate software.

Common Questions

1. Does this camera produce colour footage in complete darkness?

   Yes. The DS-2CD2167G2-SU uses ColorVu technology with a white LED rated to 30m, delivering colour video down to 0.0005 Lux. This is not enhanced greyscale - it is genuine colour imaging of clothing, vehicles, and surroundings. The LED illuminates the scene visibly, so covert low-light installations are not suited to this model.

2. Will this camera work with my existing Hikvision NVR?

   In most cases, yes. The DS-2CD2167G2-SU is a standard Hikvision IP dome using H.265+ compression and Hik-Connect compatibility. AcuSense alert classification is fully supported on Hikvision AcuSense-compatible NVRs. If your NVR is an older non-AcuSense model, the camera will still record and stream - but AI-filtered alerts at the NVR level require a compatible recorder. Check your NVR firmware version before deploying.

3. Does the built-in microphone support two-way audio?

   No. This model includes a built-in microphone for audio recording only. There is no built-in speaker, so two-way audio communication is not supported on this camera. The microphone records ambient audio alongside the video stream - conversations, alarms, or other environmental sound - but you cannot broadcast audio back through this unit.

4. What distance can this camera actually identify a person at?

   8 metres for identification using the 2.8mm lens, based on confirmed DORI figures. Recognition - enough to distinguish a person from a vehicle or determine general characteristics - is rated at 17m. Detection, where something is confirmed as present but not characterised, reaches 89m. For installations where facial identification at distances beyond 8-10m is a requirement, a camera with a tighter fixed lens or varifocal option is the correct specification.

5. How does AcuSense reduce false alarms compared to standard motion detection?

   Standard motion detection triggers on any pixel change - wind in trees, a passing headlight, or a shadow crossing the frame. AcuSense uses a deep learning model trained on human and vehicle shapes to classify each motion event before generating an alert. Only confirmed human or vehicle detections trigger the notification. The result is a significant reduction in nuisance alerts, particularly in outdoor positions with variable lighting or vegetation nearby.

6. Is this camera suitable for installation in harsh outdoor conditions in Australia?

   Yes, for standard outdoor exposures. The IP67 rating covers full dust ingress protection and water immersion to 1m for 30 minutes - more than sufficient for rain, hose-down proximity, and coastal spray in most Australian installations. The dome housing is designed for permanent wall and eave mounting. This is not rated for direct jet wash or submersion applications, but it handles normal Australian outdoor conditions without issue. It is stocked by Security Australia as part of the Hikvision Gen2 ColorVu range.

7. Does the 130 dB WDR make a practical difference at entry points?

   Yes, in high-contrast scenarios it makes a measurable difference. 130 dB WDR means the camera processes a very wide exposure range simultaneously - capturing detail in both the bright zone and the shadow in the same frame. At a building entrance with direct sunlight behind a person, a standard camera will either silhouette them or blow out the background. At 130 dB, both the face and the exterior detail are rendered in a single balanced frame. The practical benefit is most visible at dawn, dusk, and midday sun positions on east or west-facing entry points.
