Hikvision DS-2CD2347G2-LU 4MP Gen2 Outdoor ColorVu BLACK Turret Camera with Acusense & Mic 30m White LED 2.8mm

Model: DS-2CD2347G2-LU-BLACK

Who This Is For

When full-colour night imaging combined with AI-based false alarm filtering is the priority, the Hikvision DS-2CD2347G2-LU Gen2 ColorVu AcuSense Turret in black housing is a strong candidate. This model is built for installers and property owners who need outdoor coverage in eave, soffit, or wall-mount positions where a dark housing blends with the building facade - think commercial shopfronts, warehouse perimeters, residential driveways, and childcare entry points. The 2.8 mm fixed lens suits close to mid-range coverage at entrances and walkways, while the ColorVu Gen2 technology pushes full-colour imaging down to 0.0005 Lux, meaning usable colour detail well into the night without relying on IR. AcuSense human and vehicle classification actively filters pet and environmental motion triggers, so operators receive alerts that actually warrant attention rather than a flood of irrelevant events.

What This Camera Actually Does

Who Buys This Model

• Residential installers fitting eave or soffit cameras: The turret form factor and 2.8 mm lens suit close-range driveway and entry coverage, and the black housing suits dark-coloured roof lines and fascias where a white camera would stand out.
• Small business owners with evening foot traffic: Hospitality venues, small retail, and service businesses that stay open after dark benefit from colour-accurate footage of customer and staff entry points without relying on existing site lighting.
• Security integrators building Hikvision AcuSense systems: Installers specifying NVR-based systems with smart event filtering choose this camera to reduce nuisance alerts on sites where animals, trees, or passing traffic previously overwhelmed motion-based rules.
• Childcare and aged care facility managers: Sites requiring colour-accurate footage for incident documentation - and where a discreet, low-profile camera body is preferable to a visible bullet camera - match this camera's form factor and imaging output well.

Honest Assessment

The DS-2CD2347G2-LU Gen2 ColorVu does two things well: it maintains colour imaging in genuinely dark conditions and it filters motion alerts intelligently enough to be useful in practice. The combination of 0.0005 Lux sensitivity, 40 m white LED illumination, and on-camera AcuSense classification makes it a solid outdoor turret for everyday commercial and residential installs where night colour and alert accuracy both matter. H.265+ compression keeps storage and bandwidth demands manageable across multi-camera deployments.

It will not substitute for a PTZ where wide-area tracking or optical zoom is needed, and the fixed 2.8 mm lens limits effective identification range - if the target zone extends beyond 15-20 m, a 4 mm or 6 mm variant warrants consideration. The built-in microphone records audio but there is no integrated speaker, so two-way communication requires a separate device. This model is available through Security Australia and suits Hikvision NVR ecosystems best.

Before You Buy

Quick Fit Check

• Good match if: You need colour night footage at an outdoor entry point, carport, or gate where site lighting is absent or unreliable - the 40 m white LED range and 0.0005 Lux sensitivity handle this without supplementary lighting.
• Good match if: Your site generates excessive false alerts from existing motion detection and you need a camera that can distinguish a person from a vehicle, pet, or swaying branch before sending a notification.
• You may need a different model if: Your coverage requirement involves long-range identification across a large open area, a perimeter fence line, or a car park with long approaches - a bullet-style camera with a longer focal length or a PTZ camera will serve those scenarios better.

Real-World Scenarios

How It Compares

• Choose this if: Full-colour night imaging, AcuSense alert filtering, and a discreet black turret housing are all required in a single outdoor camera with IP67 protection.
• You may need a different model if: Your site has long open approaches, perimeter fence lines, or car parks requiring coverage beyond 20-25 m - a bullet-style camera with a longer focal length, or a PTZ camera with optical zoom, will deliver better identification at those distances.
• Pairs well with: A compatible Hikvision AcuSense NVR to take full advantage of smart event classification, person/vehicle search in recordings, and structured alert management across multiple cameras.

Common Questions

1. Does this camera record in colour at night without any external lighting?

   Yes. The DS-2CD2347G2-LU uses ColorVu Gen2 technology with a minimum illumination rating of 0.0005 Lux, meaning it produces colour footage in very low ambient light. When light levels drop below the sensor's threshold, the built-in white LEDs activate automatically, illuminating the scene up to 30 m and maintaining colour output. No separate floodlight or sensor light is needed.

2. Does AcuSense actually reduce false alarms, and how does it work?

   Yes, meaningfully so compared to standard pixel-based motion detection. AcuSense runs deep learning classification directly on the camera's processor. When motion is detected, the camera evaluates the shape, movement pattern, and size of the object before deciding whether it matches a human or vehicle profile. Alerts are only sent if the classification matches. Pets, foliage, vehicle headlight sweeps, and rain typically do not trigger an alert.

3. Does this camera 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 communication is not possible from the camera itself. If two-way audio is needed at the installation point, a separate audio output device or an intercom unit would be required alongside this camera.

4. Will the 2.8 mm lens cover my driveway or do I need a different focal length?

   It depends on the width and depth of the area. The 2.8 mm lens provides a wide field of view well suited to covering a broad entry zone at close to mid-range - typically up to 8-12 m for reliable identification. For longer driveway approaches or coverage of a specific zone at 15 m or more, the 4 mm or 6 mm variants of the same model deliver a tighter frame and stronger detail at distance. The depth of focus on this 2.8 mm unit starts at 2.5 m, which means very close subjects may appear slightly soft.

5. Will the white LEDs be visible and distracting at night?

   Yes, they are visible. Unlike infrared illuminators, white LEDs produce a visible light cone when active. In most outdoor security applications this is not a problem, but if the camera is mounted near bedroom windows, neighbouring properties, or hospitality areas where light intrusion is a concern, the LED intensity can be adjusted through the camera's web interface or Hikvision's iVMS-4200 platform to reduce the effect.

6. What NVR do I need to get the most out of AcuSense features?

   A Hikvision NVR with AcuSense support is required to use the full smart event set - including person/vehicle alert filtering at the recorder level, smart search by object type, and structured event logs. Connecting this camera to a non-AcuSense NVR or a third-party recorder will still produce video and basic motion events, but the AI classification features and smart alert routing will not be available. The range of compatible AcuSense NVRs is stocked by Security Australia if you need to build out a complete system.

7. How does 130 dB WDR affect footage at a backlit entrance?

   It prevents the camera from having to choose between exposing for the bright background or the darker foreground. At 130 dB, the camera captures multiple exposures per frame and combines them, retaining detail in both the bright outdoor area and the shadowed face of a person standing in a doorway. Without WDR at this level, a person standing with a bright sky or sun behind them would typically appear as a silhouette in standard footage.
