Hikvision DS-2CD2347G2-LSU/SL 4MP Gen2 ColorVu Turret Camera Acusense Speaker Strobe Mic 30m White LED 2.8mm

Model: DS-2CD2347G2-LSU/SL

Who This Is For

When active deterrence at the point of detection is the priority, not just passive recording, the DS-2CD2347G2-LSU/SL is the camera most installers reach for. This is Hikvision's Gen 2 Live-Guard turret - combining ColorVu full-colour night imaging, AcuSense human and vehicle classification, a built-in strobe light, and a speaker with microphone into a single IP67-rated housing. It suits small business owners, property managers, and residential installers who want a camera that reacts to confirmed intrusions rather than simply logging them. The 2.8mm lens gives a wide field of view suited to eave, soffit, and wall mounting at entry points, laneways, carparks, and back yards - anywhere that benefits from immediate visible and audible challenge when a person or vehicle is detected after hours. At 4MP with a 1/1.8" sensor and 0.001 lux minimum illumination, it produces usable colour footage in near-darkness without relying on infrared.

What This Camera Actually Does

Who Buys This Model

• Small business owners running unstaffed sites overnight: The AcuSense-triggered strobe and alarm mean the camera actively challenges confirmed intruders at 2am without requiring a monitoring centre to intervene first.
• Residential installers covering rear yards and side gates: IP67 weatherproofing and a -40°C to 60°C operating range handle Australian conditions from Far North Queensland heat to alpine winters, while the 2.8mm lens covers wide entry zones from eave height.
• Property managers upgrading from standard IR cameras: Sites that have experienced nuisance alerts from motion-based cameras switch to this model specifically for AcuSense's human and vehicle filtering, reducing false alarm callouts.
• Installers specifying standalone edge recording: The 256GB microSD slot means this camera can record independently on sites where network infrastructure is limited or where a redundant local copy is required alongside NVR storage.

Honest Assessment

The DS-2CD2347G2-LSU/SL does three things genuinely well: colour night imaging with a sensor large enough to work before the white LED even activates, AcuSense classification that materially reduces false alarms compared to standard motion detection, and a strobe-plus-alarm response tied to confirmed human or vehicle targets. The 120dB WDR and H.265+ compression round out a strong feature set for the price point. Available through Security Australia, it suits any outdoor perimeter position where active deterrence is valued alongside recording. Where it will not serve as well: the fixed 2.8mm lens cannot be changed, so longer approaches beyond roughly 11-12 metres recognition distance (per DORI data) are better covered by a varifocal or bullet camera. The turret housing also suits eave and wall mounting more naturally than pole or parapet positions where a bullet form factor gives better IR or white light directionality. If the primary need is long-range identification rather than wide-area deterrence, a different model will serve better.

Before You Buy

Quick Fit Check

• Good match if: You are covering an outdoor entry point or yard where active deterrence (strobe and audible alarm on confirmed human/vehicle detection) is needed alongside 4MP colour recording, and mounting is at eave or wall height within the 2.8mm lens's field of view.
• Good match if: The site has no stable power run to the camera position - single Cat5e/Cat6 PoE cabling handles both data and power (802.3af Class 3), and the 256GB microSD slot provides a local recording backup independent of the NVR.
• You may need a different model if: The approach you need to cover exceeds 20-25 metres and face or plate identification is required - a varifocal bullet or turret with a longer focal length will deliver better recognition distances for that scenario.

Real-World Scenarios

How It Compares

• Choose this if: You need active deterrence built into the camera - strobe and audible alarm triggered by AcuSense classification - combined with full-colour night imaging and two-way audio in a single IP67 turret body.
• You may need a different model if: The primary requirement is long-distance identification beyond 12 metres - a varifocal turret or bullet camera with a longer focal length will deliver better recognition and identification distances for corridors, long driveways, or car park approaches.
• Pairs well with: An AcuSense-compatible NVR with sufficient PoE channel capacity - this ensures the strobe and alarm event rules can be managed centrally and AcuSense alerts are filtered and logged correctly across multi-camera installations.

Common Questions

1. Does the strobe and alarm fire on every motion event, or only on people and vehicles?

   Only on AcuSense-confirmed human or vehicle targets. The camera's deep learning engine classifies detected objects before triggering the strobe or audio alarm. Environmental motion - a blowing branch, a cat, headlight reflections passing across a fence - will not activate the deterrence outputs under normal AcuSense event configuration. This is the primary reason installers choose this model over a standard motion-triggered alarm camera.

2. Will this camera produce colour footage in a completely dark area with no external lighting?

   Yes. The built-in 30m white LED illuminator activates in zero-lux conditions, producing colour footage rather than switching to black and white. The 1/1.8" sensor and F1.6 aperture also enable colour imaging down to 0.001 lux, which covers most scenes with minimal ambient light before the LED is even needed.

3. What is the practical recognition distance at the 2.8mm lens setting?

   Per published DORI data, recognition distance is 11.6 metres and identification distance is 5.8 metres at 2.8mm. Detection range extends to 58.2 metres. This means the camera can detect that a person is present from nearly 60 metres away, but to positively identify a face or read fine detail, the subject needs to be within approximately 6 metres. For longer-approach recognition requirements, a varifocal model will serve better.

4. Does this camera support two-way audio, or is it receive-only?

   Yes, full two-way audio is supported. Both a built-in microphone and a built-in speaker are confirmed in the hardware specification. This allows real-time voice communication through a compatible NVR interface or the Hik-Connect mobile app - not just one-way listening.

5. Does the DS-2CD2347G2-LSU/SL need a special PoE switch, or will a standard 802.3af switch work?

   A standard 802.3af switch is sufficient. The camera draws PoE Class 3, which falls within the 15.4W budget that all 802.3af compliant switches provide per port. PoE+ (802.3at) is not required. However, confirm your switch's total power budget if running multiple cameras - underpowered budget switches that cannot sustain full draw across all ports simultaneously can cause issues when white LED illuminators are active.

6. Will the camera record locally to a microSD card if the NVR goes offline?

   Yes. The microSD/SDXC slot supports up to 256GB of on-board storage. The camera can be configured to record continuously or on event trigger directly to the card. This provides a local backup recording that continues independently if network connectivity or the NVR is unavailable - a useful failsafe on sites with intermittent network infrastructure.

7. Do I need an AcuSense-compatible NVR to use the strobe and alarm deterrence functions?

   No - the strobe and alarm can be configured to trigger directly from the camera's own event settings via its web interface, without relying on an NVR at all. However, for centralised event management across multiple cameras, receiving AcuSense-filtered alerts on a recorder interface, and managing alarm rules at scale, an AcuSense-compatible Hikvision NVR is strongly recommended. Connecting this camera to a non-compatible recorder and relying solely on the recorder's motion detection will not pass AcuSense event classification through to the recorder's alert system. Stocked by Security Australia, compatible NVR options are listed separately on the site.
