Hikvision DS-2CD2047G2-LU 4MP Gen2 Outdoor ColorVu Mini Bullet Camera with Acusense & Mic 30m White LED 2.8mm

Model: DS-2CD2047G2-LU

Who This Is For

When full-colour night footage and intelligent motion filtering are both priorities, the DS-2CD2047G2-LU sits in a practical middle ground that many comparable mini bullets miss. This is a 4MP outdoor camera with Hikvision ColorVu and AcuSense built in - meaning it produces colour images in near-total darkness using white LED illumination, and it classifies detections as human or vehicle rather than triggering on passing headlights or wind-blown trees. It suits installers and security-conscious property owners covering entry points, car parks, driveways, or building perimeters where infrared black-and-white footage is no longer considered acceptable for evidentiary or monitoring purposes. The compact mini bullet housing mounts cleanly on eaves, fascia boards, or external walls without the bulk of a full-size bullet camera, and the 2.8mm lens gives a wide field of view suited to shorter-range coverage zones up to roughly 13 metres for facial recognition.

What This Camera Actually Does

Who Buys This Model

• Residential installers: Specifying colour-at-night coverage for driveways and front entries where homeowners want footage that shows a person's clothing or a vehicle's colour - details that standard IR cameras cannot provide in darkness.
• Small business owners: Covering car parks, external entry doors, or delivery bays who need notification filtering - AcuSense means alerts come through for people and vehicles, not every passing insect or tree branch.
• Body corporate managers: Adding cameras to apartment complex perimeters, bin enclosures, or visitor parking areas where a compact, unobtrusive bullet profile is preferred over a large housing and colour night footage supports incident review.
• Security integrators: Deploying mixed camera systems who need a cost-effective AcuSense-capable bullet for lower-priority zones alongside PTZ or higher-resolution cameras at key watch points - the DS-2CD2047G2-LU sits within budget for those secondary positions.

Honest Assessment

The DS-2CD2047G2-LU does two things genuinely well: it delivers colour footage in complete darkness through the combination of a wide-aperture lens and white LED illumination, and it significantly reduces notification fatigue through AcuSense human and vehicle classification. For a mini bullet at this price point, having both features in an IP67-rated housing with a built-in microphone represents solid value for standard residential and light commercial applications. The 4MP resolution with H.265+ compression is practical for most monitoring distances the 2.8mm lens covers. Where it falls short: the white LED illumination is visible when activated - it glows warm white rather than being covert like IR, which suits deterrence but may not suit covert monitoring applications. For sites needing coverage beyond 30 metres, a full-size bullet or varifocal lens option will serve better. This product is supplied by Security Australia and requires a compatible AcuSense-capable NVR to use AI filtering features - a standard older NVR will record video but may not pass through classified alerts.

Before You Buy

Quick Fit Check

• Good match if: You need colour night footage on a driveway or car park entry where the illumination zone sits within 30 metres and colour detail - vehicle colour, clothing - is a priority for your footage review requirements.
• Good match if: You are receiving excessive false alert notifications from an existing motion-detection camera and need AcuSense human and vehicle classification to filter alerts down to genuine human or vehicle events only.
• You may need a different model if: Your coverage zone exceeds 30 metres, or you need optical zoom to adjust coverage after installation - a varifocal bullet or PTZ camera from the Security Australia range would be more appropriate for those requirements.

Real-World Scenarios

How It Compares

• Choose this if: Full-colour night footage and AcuSense alert filtering are both required in a compact outdoor bullet housing - this model delivers both at a price point below full-size bullet alternatives with the same feature set.
• You may need a different model if: Your site requires coverage beyond 30 metres, a varifocal lens to adjust the field of view after installation, or covert IR night imaging without visible white light - a varifocal bullet or dual-light model would be more appropriate.
• Pairs well with: An AcuSense-capable PoE NVR to unlock smart event recording and AI-based search by human or vehicle classification across recorded footage.

Common Questions

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

   Yes. The DS-2CD2047G2-LU uses ColorVu technology with a built-in white LED that activates in low or zero ambient light, producing colour footage down to 0.0005 Lux and 0 Lux with the LED active. You do not need to install a separate floodlight - the camera provides its own illumination up to 30 metres. The LED produces a visible warm glow when active, so it is not covert.

2. Will AcuSense stop me from getting false alerts from my phone at night?

   Yes, that is the primary purpose of AcuSense. The camera analyses movement and classifies the object as human or vehicle before triggering a push notification. Common false alarm sources - cats, insects near the lens, headlight reflections on a wall, blowing foliage - do not match the human or vehicle classification criteria and are filtered out. You will still need a compatible NVR or the Hik-Connect app configured to use AcuSense event types rather than standard motion detection for this to take effect.

3. What distance can this camera recognise a face at with the 2.8mm lens?

   The confirmed DORI identification distance for the 2.8mm lens is 6 metres. Recognition - sufficient to confirm a known person - is rated at 13 metres. Detection, which confirms a human is present but not their identity, extends to 65 metres. These figures are the practical benchmarks for planning camera placement: if you need to identify faces, the subject needs to be within 6 metres of the lens.

4. Does this camera work with any NVR, or does it need a specific Hikvision recorder?

   It will record video to any ONVIF-compatible NVR, including non-Hikvision recorders. However, AcuSense smart events, human and vehicle classification filtering, and AI-based footage search only function when connected to a Hikvision NVR that explicitly supports AcuSense. Non-AcuSense NVRs will record standard motion events only. For full AI feature access, confirm your NVR model supports AcuSense before purchasing - this is listed in the NVR specifications on the product page at Security Australia.

5. Does the built-in microphone support two-way communication?

   No. The DS-2CD2047G2-LU has a built-in microphone for audio capture and recording, but there is no built-in speaker. Two-way audio requires both a microphone and a speaker in the camera - this model only has the microphone. You can hear audio from the camera's location, but you cannot broadcast audio back through the camera itself.

6. Does this camera handle strong backlight, such as a sun-facing entry or a scene with bright and dark areas?

   Yes. The 130 dB Wide Dynamic Range rating is specifically designed for mixed-lighting scenes where a standard camera would either blow out the bright zones or lose detail in shadowed areas. In practical terms, this covers sun-facing doors, areas under covered walkways adjacent to open courtyards, or any scene where a bright background sits behind a subject you need to see clearly.

7. Is this camera suitable for coastal or high-humidity outdoor locations?

   Yes, the IP67 rating confirms it is dust-tight and protected against water immersion up to 1 metre. This covers sustained rain, high humidity, and coastal spray exposure. IP67 is a certified standard, not a marketing claim - it covers the full housing assembly including cable entries. For direct saltwater spray or submersion-prone locations, additional housing protection should be considered.
