Product Overview
Combining full-colour night vision with active deterrence, the DS-2CD2T47G2-LSU/SL is a 4MP outdoor bullet camera built for perimeter walls, driveways, commercial entry points, and shopfronts where visible response to intrusion matters as much as image quality. ColorVu imaging and a large aperture lens deliver colour video down to 0.0005 Lux, supported by a 60m white light illuminator that lights the scene rather than relying on greyscale IR footage. Featuring AcuSense deep learning to classify humans and vehicles separately from general motion, this model reduces unnecessary alerts while keeping response focused on genuine threats. It also includes a built-in siren and strobe for real-time active deterrence, two-way audio via a built-in microphone and speaker, and a 130dB WDR sensor for strong backlight environments. The IP67-rated bullet housing suits permanent wall or eave mounting in exposed outdoor locations.
Key Capabilities
ColorVu Full-Colour Night Vision
The large aperture lens and ColorVu sensor capture colour video down to 0.0005 Lux, supported by a 60m white light illuminator. Outdoor scenes at night are recorded in colour rather than greyscale, preserving details like clothing colours and vehicle paint for review and evidence.
Active Siren and Strobe Deterrence
When a detection event triggers, the built-in siren and strobe can activate automatically to warn intruders before they advance further. This makes the DS-2CD2T47G2-LSU/SL more than a recording device for perimeter and driveway positions where an immediate visible and audible response is required.
AcuSense Human and Vehicle Classification
Deep learning analysis separates humans and vehicles from other motion sources such as animals, foliage, and lighting changes. Alerts are filtered to relevant targets, reducing notification fatigue for operators monitoring busy outdoor environments like car parks, yards, and commercial entries.
Two-Way Audio
A built-in microphone and built-in speaker allow real-time two-way voice communication directly through the camera. Operators can speak to individuals on site from a remote monitoring position, adding an active management layer to entry points, loading areas, and unmanned locations.
130dB Wide Dynamic Range
A 130dB WDR sensor manages scenes with extreme contrast between bright and shadowed areas. Shopfronts with strong window glare, entry gates with direct sunlight, and driveways with headlight exposure are all handled without losing detail in underexposed or overexposed zones.
H.265+ Compression and IP67 Housing
H.265+ encoding reduces storage and bandwidth requirements compared to older compression formats, which matters when recording colour footage continuously at 4MP. The IP67-rated bullet housing protects against dust ingress and water exposure for reliable installation in exposed outdoor positions.
Best For
- Commercial Driveways and Entry Points: The 60m white light and AcuSense vehicle classification make this model well suited to monitoring vehicle approach paths and entry gates where both colour identification and targeted alerts are priorities.
- Perimeter Walls and Fence Lines: The directional bullet housing suits wall mounting aimed along fence lines or access routes, and the siren plus strobe can activate on detection without requiring a separate deterrence device.
- Shopfronts and Loading Dock Approaches: 130dB WDR handles backlit facades and headlight exposure while ColorVu preserves colour detail at night, supporting both live monitoring and after-the-fact review at commercial premises.
- Unmanned Outdoor Sites Requiring Remote Interaction: Two-way audio through the built-in speaker and microphone allows operators to communicate directly with individuals on site, useful at unmanned yards, storage facilities, and industrial compounds.
Why Choose the DS-2CD2T47G2-LSU/SL
The DS-2CD2T47G2-LSU/SL brings together capabilities that typically require separate devices. A single bullet camera delivers colour night footage via ColorVu, human and vehicle classification via AcuSense, active deterrence via a built-in siren and strobe, and two-way audio via confirmed built-in speaker and microphone. A basic outdoor bullet at a similar resolution would offer none of these response layers. The 130dB WDR sensor addresses contrast challenges that lower-grade sensors handle poorly at commercial entry points. H.265+ compression keeps storage consumption in check when recording colour footage around the clock. For installers and site managers who need perimeter coverage that detects, deters, and communicates without adding accessories, the DS-2CD2T47G2-LSU/SL available at Security Wholesalers is a considered choice for outdoor bullet positions where passive recording alone is not sufficient.
Buyer Decision Tips
Fixed 2.8mm Lens Coverage: This model uses a fixed 2.8mm lens, which provides a wide field of view suited to shorter approach distances and broad coverage of entry areas. If you need to frame a specific narrow corridor or cover a longer distance with tighter framing, a 4mm or 6mm fixed lens variant would be more appropriate. Confirm your mounting distance and coverage width before selecting this specific variant.
White Light vs. Covert Surveillance: The 60m white light illuminator is visible to anyone in the camera’s field of view at night. This is an advantage for deterrence and colour accuracy, but it is not appropriate for covert monitoring positions where you do not want to draw attention to the camera. If the installation requires discreet night operation, a camera using IR rather than white light illumination would be more suitable.

Ideal Use Cases
Residential and Commercial Driveways
The 2.8mm wide-angle lens covers broad driveway approaches, AcuSense vehicle detection targets relevant activity, and the 60m white light illuminates the full approach path at night in colour. The siren and strobe can activate immediately on detection without requiring a separate alarm device.
Industrial Yards and Compounds
IP67 protection suits permanent exposure to dust, rain, and moisture at industrial sites. AcuSense human detection at perimeter positions reduces false triggers from vehicles and machinery movement while keeping alert sensitivity high for pedestrian intrusion.
Shopfronts and Retail Entries
130dB WDR manages the contrast between bright shopfront lighting and dark street backgrounds. ColorVu preserves colour in low-light conditions overnight, and the built-in two-way audio allows staff or remote operators to communicate with individuals at the entry.
Loading Docks and Delivery Areas
Vehicle classification via AcuSense distinguishes delivery vehicles from unauthorised access. The bullet housing allows directional aiming along the dock approach, and two-way audio supports remote instruction to drivers or personnel during out-of-hours deliveries.
Perimeter Fence Lines and Gates
Wall or pole mounting on a perimeter fence line benefits from the directional bullet form factor. Active deterrence through the built-in siren and strobe means the camera can intervene on detection events at after-hours perimeter positions before an intruder reaches the main building.
Choosing the Right Model
- Choose this model if: You need a single outdoor bullet that combines 4MP colour night vision, AcuSense classification, active siren and strobe deterrence, and two-way audio at perimeter, driveway, and commercial entry positions, and the 2.8mm wide angle suits the mounting distance and coverage area.
- Choose a different model if: You need to cover a longer, narrower approach and require a tighter field of view – a 4mm or 6mm fixed lens variant would frame a more distant subject more precisely. If the installation requires discreet night operation without a visible illuminator, a camera using IR rather than white light would be more appropriate. If active deterrence is not required, a standard ColorVu bullet without siren and strobe may be a more economical fit.
FAQs
- Does the DS-2CD2T47G2-LSU/SL record in colour at night without any external lighting?
Yes. The ColorVu sensor and large aperture lens capture colour video down to 0.0005 Lux, meaning the camera produces colour footage in very low ambient light. The built-in 60m white light illuminator adds further illumination when natural or artificial light is insufficient, ensuring colour footage rather than greyscale even in complete darkness. - What does the active deterrence function actually do when triggered?
When a detection event is confirmed, the camera can activate its built-in siren and strobe light in real time. This is designed to warn individuals who have entered or are approaching a monitored area. The deterrence can be triggered automatically based on AcuSense detection rules or via manual activation from a compatible NVR or monitoring interface. - Is the two-way audio genuinely built in, or does it require an external microphone and speaker?
Both the microphone and speaker are built into the camera body. No external audio devices are required for two-way communication. An audio and alarm interface is also available on this model for connection to additional external audio or alarm equipment if needed for the installation. - What is the field of view and identification range for the 2.8mm variant?
At 2.8mm, the DORI ratings are: Detect at 65m, Observe at 21m, Recognise at 13m, and Identify at 6m. The depth of focus starts at 2.5m and extends to infinity. The 2.8mm lens provides a wide horizontal field of view, making it appropriate for broad coverage of entry areas, driveways, and open outdoor zones rather than narrow corridor framing. - How does AcuSense reduce false alerts compared to standard motion detection?
Standard motion detection triggers on any pixel change in the frame, including wind-blown foliage, passing vehicle headlights, and animals. AcuSense uses deep learning to classify detected objects as human or vehicle specifically. Alerts are only generated for those target classes, which significantly reduces notifications from irrelevant sources in busy outdoor environments. - Is this camera suitable for installation in exposed outdoor locations with rain exposure?
Yes. The IP67 rating confirms the housing is fully sealed against dust ingress and protected against immersion in water up to 1m for 30 minutes. For typical outdoor wall and eave mounting on driveways, perimeters, and building facades, IP67 provides suitable protection for ongoing exposure to Australian weather conditions. - What NVR or recorder is this camera compatible with?
The DS-2CD2T47G2-LSU/SL is a Hikvision IP camera using standard ONVIF and Hikvision protocol, compatible with Hikvision NVRs that support AcuSense and ColorVu features. For full access to active deterrence triggering, two-way audio management, and AcuSense alert filtering, a compatible Hikvision NVR is recommended. This camera is part of the Security Wholesalers range, where compatible recorders and accessories are also available.
