Hikvision DS-2CD2547G2-LS 4MP Gen2 Outdoor ColorVu Mini Dome Camera with Acusense White LED

Model: DS-2CD2547G2-LS

Who This Is For

For property managers and installers who need full-colour footage at night without the limitations of infrared black-and-white imaging, the Hikvision DS-2CD2547G2-LS delivers 24/7 colour through an F1.0 super-aperture lens paired with white LED illumination. This is a compact outdoor mini dome suited to eaves, building facades, car parks, retail entries, and childcare exteriors where identifiable colour detail matters - clothing colour, vehicle colour, and scene context that IR simply cannot provide. The IK08 vandal resistance rating makes it viable for semi-public mounting positions where the housing may be exposed to interference. AcuSense deep learning filters human and vehicle detections from environmental false triggers, which is particularly useful in outdoor settings where trees, insects, and lighting changes would otherwise generate constant alerts. Available in 2.8 mm and 4 mm lens options to match the specific coverage distance required at each install point.

What This Camera Actually Does

Who Buys This Model

• Retail and hospitality operators: Businesses needing colour footage of customer-facing areas, car parks, and after-hours entry points where clothing and vehicle colour form part of incident reporting.
• Strata and property managers: Multi-unit residential buildings with exposed common area mounting positions where IK08 vandal resistance is specified and 24/7 colour is required for resident and visitor identification.
• Childcare and education facilities: Operators who require colour imaging of entry points, play areas, and car drop-off zones around the clock, including early morning and evening pick-up periods with low ambient light.
• Security integrators replacing IR dome cameras: Installers upgrading existing sites where monochrome night footage has proven insufficient for post-incident review, replacing like-for-like in mini dome form factor with colour capability.
• Small business owners on mixed indoor/outdoor systems: Operators combining this outdoor mini dome with indoor models on a single Hikvision NVR where AcuSense classification is used to manage notification volume across the entire system.

Honest Assessment

The DS-2CD2547G2-LS does colour-at-night genuinely well. The F1.0 aperture combined with white LED illumination means the camera produces identifiable colour footage in conditions where a standard IR camera would show a flat grey image. AcuSense classification is a practical feature that reduces false alerts from outdoor environments without requiring manual zone tuning for every weather change. The 130 dB WDR handles high-contrast outdoor lighting reliably, and the IP67/IK08 ratings make it an appropriate choice for exposed mounting positions. Where this camera has limits: the white LEDs are visible when active, which some environments find intrusive - a covert or IR-only setup would need a different model. DORI identification sits at 8 m on the 4 mm lens, so it is not suited to monitoring long driveways or wide open areas where you need recognition at distance. For those applications, a bullet camera with longer IR or a varifocal lens would be more appropriate. The DS-2CD2547G2-LS is available through Security Australia.

Before You Buy

Quick Fit Check

• Good match if: You need full-colour night footage at a building entry, car park, or outdoor common area where identifying clothing or vehicle colour is important and IR monochrome footage has proven insufficient.
• Good match if: The mounting position is semi-exposed and within reach, and you require an IK08-rated housing that can handle both driven rain and incidental physical contact without compromising the camera.
• You may need a different model if: Your monitoring distance exceeds 15-20 m or you need to cover a long driveway or open yard - a varifocal bullet camera or a model with longer-range IR would give you the detection and recognition distances that this fixed-lens mini dome cannot reach.

Real-World Scenarios

How It Compares

• Choose this if: Your priority is full-colour night footage in a compact outdoor dome format with vandal resistance - the F1.0 aperture and white LED combination gives genuine colour in near-darkness that IR models cannot match.
• You may need a different model if: Your coverage area requires detection or recognition at distances beyond 30 m, or you need to monitor a long external perimeter - a varifocal bullet camera with longer IR range would be the more appropriate product type for that application.
• Pairs well with: A Hikvision NVR with AcuSense support to enable human/vehicle classification at the recorder level, and a PoE switch or PoE NVR to simplify cabling at each camera position.

Common Questions

1. Does this camera actually record in colour at night, or does it switch to black and white?

   Yes, it records in colour at night. The DS-2CD2547G2-LS uses ColorVu technology - an F1.0 super-aperture lens that collects substantially more light than standard lenses, combined with white LED supplemental illumination. There is no IR mode and no monochrome fallback. The camera produces colour footage 24 hours a day regardless of ambient light levels.

2. Will the white LEDs be visible at night?

   Yes, they will be visible. Unlike IR LEDs which emit light outside the visible spectrum, the white LEDs on ColorVu cameras produce a faint visible warm glow when illuminating a scene. This is normal and by design. The effect is subtle at distance but will be noticeable in a dark environment. This is worth discussing with the end user before selecting a mounting position adjacent to windows or sleeping areas.

3. What does AcuSense actually do, and do I need a special NVR for it to work?

   AcuSense classifies detected objects as human or vehicle using deep learning, and suppresses alerts triggered by animals, insects, foliage, and lighting changes. The classification runs on the camera itself, so basic human/vehicle filtering is available without a smart NVR. However, to use human/vehicle classification as a search filter or to trigger AcuSense-specific recording rules at the recorder, you will need a compatible Hikvision NVR that supports AcuSense smart events. Check your NVR model's specifications before configuring advanced smart recording rules.

4. How far can this camera identify a person clearly?

   On the 4 mm lens, the DORI identification distance is 8 m. On the 2.8 mm lens it is 6 m. Identification in DORI terms means sufficient detail to confirm individual identity. Recognition (confirming a person is the same individual seen before) is 16 m on the 4 mm lens. Detection (confirming a person is present in the frame) extends to 77 m on the 4 mm lens. For applications requiring face-level identification beyond 8 m, a longer focal length or a higher-resolution model would be required.

5. Will this camera work in a scene with strong backlighting, like a glass entry facing the sun?

   Yes, the 130 dB WDR is designed for exactly this scenario. When a subject is silhouetted against a bright background - sunlit glass, open sky, or a lit street - a camera without strong WDR will either wash out the background or lose detail in the shadow area. At 130 dB, the DS-2CD2547G2-LS processes both simultaneously, maintaining usable detail across the full exposure range of the frame. This is one of the more demanding WDR specifications in the 4MP mini dome category.

6. Is there two-way audio on this camera?

   Not as a standalone built-in feature. The DS-2CD2547G2-LS includes an audio and alarm interface, which allows connection of an external microphone and external speaker. It does not have a built-in microphone and speaker in the way some cameras do. If audio monitoring or two-way communication is a requirement, plan for appropriate external audio accessories at the installation point. Confirm interface compatibility with your NVR and cabling plan before installation. The DS-2CD2547G2-LS is stocked by Security Australia.

7. Which lens should I choose - 2.8 mm or 4 mm?

   Choose the 2.8 mm for wide coverage of smaller areas such as entry foyers, corridors, and compact car parks where you need maximum horizontal spread (112 degrees). Choose the 4 mm where the monitored area is longer and narrower - a driveway approach, a walkway, or a car park lane - and where pushing identification distance from 6 m to 8 m matters. Note that these are separate product variants, not a varifocal lens on a single camera. Select the correct focal length at time of purchase.
