Product Overview
Combining active deterrence with Smart Hybrid Light technology, the Hikvision DS-2CD2087G2H-LIU/SL is an 8MP ColorVu mini bullet camera built for perimeter protection at driveways, building entries, car parks, and shopfronts. When AcuSense detects a human or vehicle target, the camera automatically switches from infrared to white light illumination, triggers a built-in strobe, and can broadcast an audio alert through the integrated speaker – creating a real-time visual and audible response rather than a silent recording. The Super Confocal F1.0 lens delivers full-colour footage down to 0.0005 Lux, while 130dB WDR handles strong backlighting at entry points. Available with a 2.8mm or 4mm fixed lens, IP67-rated housing ensures the unit holds up in exposed outdoor installations. H.265+ compression keeps storage demands manageable without sacrificing image quality at 3840 x 2160 resolution.
Key Capabilities
Liveguard Active Deterrence
A built-in strobe light and speaker respond the moment a human or vehicle target is detected, delivering an on-the-spot visual and audio warning. This goes well beyond passive recording, making the camera useful as a first response tool at unattended perimeter points.
Smart Hybrid Light Illumination
In Smart mode the camera operates on infrared at night and switches to white light only when a classified target is detected. This preserves full-colour evidence capture for genuine events without running the white light constantly, extending its effective use at residential and commercial perimeters.
Super Confocal F1.0 ColorVu Lens
The F1.0 aperture Super Confocal lens collects significantly more light than a standard camera lens, enabling colour imaging at 0.0005 Lux. Even at the threshold of total darkness, the sensor produces colour-accurate footage before the white light activates.
AcuSense Human and Vehicle Detection
Deep learning algorithms classify targets as human or vehicle and filter out irrelevant motion from animals, foliage, and passing headlights. This keeps event logs focused on actionable detections and ensures the deterrence response triggers for the right reasons.
130dB Wide Dynamic Range
Building entrances and gate lines frequently put subjects in front of bright sky or artificial light sources. The 130dB true WDR balances exposure across the frame so number plates and faces remain legible even when the background is heavily backlit.
Built-in Microphone and Speaker
With both a built-in microphone and speaker confirmed on-board, the DS-2CD2087G2H-LIU/SL supports two-way audio communication through compatible software. The microphone also provides continuous ambient audio capture alongside video, adding useful context to recorded events.
Best For
- Driveway and Gate Entries: The directional bullet housing paired with the 4mm lens focuses coverage along the approach path, while the strobe and speaker create an immediate deterrence response when a person or vehicle is detected entering the zone.
- Retail Shopfront and Car Park Perimeters: Smart Hybrid Light delivers full-colour footage of vehicle movements and foot traffic after hours, with AcuSense filtering keeping after-hours alert volumes manageable for operators.
- Residential Side Gates and Back Fences: The 2.8mm lens option provides a 102-degree horizontal field of view suitable for covering wide residential zones from a single mount point, with IP67 weatherproofing handling exposed outdoor positions.
- Building Entrances with Backlight Challenges: The 130dB WDR manages difficult lighting at lobby entries and access points where strong interior or exterior light sources would wash out standard cameras, keeping faces and clothing detail visible in the frame.
Why Choose the DS-2CD2087G2H-LIU/SL
The DS-2CD2087G2H-LIU/SL brings together features that most 8MP bullet cameras in this category separate across different product lines. The Liveguard strobe and speaker sit alongside AcuSense classification on the same unit, so the deterrence response is triggered by verified human or vehicle targets rather than every motion event. The Smart Hybrid Light system means the camera conserves white light output for genuine detections, keeping the scene in infrared the rest of the time. The Super Confocal F1.0 lens adds a meaningful low-light advantage over cameras with slower apertures, producing usable colour footage before the supplemental lighting even activates. At 8MP the sensor captures 3840 x 2160 resolution, giving operators the ability to zoom into recorded footage for identification without a separate higher-resolution device. Available through Security Wholesalers with a choice of 2.8mm or 4mm fixed lens to match the installation geometry.
Buyer Decision Tips
Lens Selection – 2.8mm vs 4mm: The 2.8mm lens covers a 102-degree horizontal field of view and is the better choice for wide open areas such as yards, open parking bays, or shopfronts where the camera is mounted close to the monitored zone. The 4mm lens narrows to 88 degrees horizontal and is suited to corridor-style approaches, driveways, and entry lanes where the camera is set further back and needs to push detail further into the scene. The DORI detect distance on the 2.8mm is 89m, so for longer approaches the 4mm will provide better identification performance at distance. Choose your lens before ordering as both are fixed focal length and cannot be adjusted after installation.
Smart Hybrid Light Mode Selection: The camera supports 3 illumination modes: IR only (standard night vision, no colour), white light only (constant full-colour night vision at cost of visible light output), and Smart mode (IR by default, switches to white light with strobe on human or vehicle detection). For most perimeter installs Smart mode is the practical default. If the installation requires constant colour footage overnight regardless of detection events, such as a 24-hour attended car park, white light mode may be more appropriate. Confirm the recording platform supports event-based mode switching if dynamic control is needed.

Ideal Use Cases
Residential Driveway Monitoring
The 4mm lens option provides focused coverage along a driveway approach. AcuSense classification ensures the strobe and speaker deterrence triggers for genuine vehicle or person detections rather than passing traffic or neighbourhood animals, keeping night-time activations relevant.
Commercial Yard and Loading Area
The IP67-rated bullet housing is suited to wall mounting on warehouses and outbuildings. The Smart Hybrid Light switches to full-colour with strobe activation when personnel or vehicles are detected in loading and storage zones after hours, providing both deterrence and colour evidence in a single unit.
Retail Shopfront and Car Park Entry
The 2.8mm lens covers wide open frontages from a single mount point. The 130dB WDR manages backlit scenes where shop windows or security lighting creates contrast challenges, keeping subject detail visible in the frame during early morning and evening trading hours.
Fence Line and Side Access Coverage
Mounted at the corner of a building or on a perimeter fence post, the bullet form factor directs coverage along fence lines and side access paths. The visible housing provides a clear deterrence signal during daylight, supported by strobe and speaker activation at night.
Building Entry and Reception Approach
The 130dB WDR and F1.0 lens handle the backlight conditions common at building entries where subjects stand in front of exterior daylight or lit lobbies. The built-in microphone captures ambient audio alongside video, adding context to access events recorded at the entry point.
Choosing the Right Model
- Choose this model if: You need a single camera to both record and actively respond to perimeter intrusions, particularly at driveways, yard access points, or shopfronts where a real-time strobe and audio alert on human or vehicle detection is part of the security response plan alongside 8MP colour recording.
- Choose a different model if: The installation requires coverage of a very large area such as a wide open car park or building forecourt from a single camera position. In that scenario a wider-angle or motorised varifocal bullet camera with greater horizontal coverage or zoom flexibility would be a more practical fit for the geometry.
- Choose a different model if: Long-range IR detection beyond 30 metres is the primary requirement, such as monitoring a long rural driveway or extended fence line. A camera with a dedicated long-range IR module and a longer focal length would provide better target identification at those distances.
- Choose a different model if: The installation is purely indoor with no exposure to weather. The IP67 housing and active deterrence features are designed for outdoor perimeter use and a compact indoor dome would be a more proportionate choice for interior spaces.
FAQs
- What triggers the strobe and speaker on the DS-2CD2087G2H-LIU/SL?
The strobe and speaker are triggered by the AcuSense detection engine when a human or vehicle target is classified within the configured detection zone. Because AcuSense uses deep learning to filter out non-human non-vehicle motion, the deterrence response is linked to verified targets rather than general movement, reducing the likelihood of nuisance activations from wind, foliage, or small animals.
- Does the camera record in colour at night without the white light running constantly?
Yes. In Smart mode the camera uses infrared illumination as its default night mode, which produces monochrome footage. When AcuSense detects a human or vehicle, it switches to white light illumination to capture full-colour footage of that event. This means colour recording is available for genuine detections without requiring the white light to remain on all night. Alternatively, white light only mode can be selected for constant colour night recording.
- What is the confirmed illumination range of the DS-2CD2087G2H-LIU/SL?
The Smart Hybrid Light system provides illumination up to 30 metres. This covers the typical driveway, access lane, or building approach distance where this camera is most commonly deployed. For longer distances beyond 30 metres, the illumination effectiveness will reduce and subject detail in recorded footage at those extremes will diminish accordingly.
- Can the camera be used for two-way audio communication?
The DS-2CD2087G2H-LIU/SL has both a built-in microphone and a built-in speaker confirmed on-board, which means two-way audio is supported through compatible NVR software or VMS platforms that provide this functionality. The microphone also operates independently for continuous ambient audio capture as part of standard video recording.
- Which lens should I choose for a standard residential driveway installation?
For most residential driveways the 4mm lens is the practical choice. It provides an 88-degree horizontal field of view, which suits corridor-style approaches where the camera is mounted at a moderate distance from the monitored zone. The 2.8mm lens at 102 degrees is better suited to shorter distances and wider open areas such as a front yard or open car bay. Both are fixed focal length, so the selection needs to be made before ordering.
- Is the DS-2CD2087G2H-LIU/SL suitable for mounting in an exposed outdoor location?
Yes. The camera carries an IP67 ingress protection rating, meaning it is dust-tight and rated against water immersion, making it suitable for wall mounting on building exteriors, fence posts, and other fully exposed outdoor positions. The bullet housing is designed to withstand direct weather exposure across standard Australian outdoor conditions.
- Where can I find the datasheet and does Security Wholesalers stock both lens variants?
The official datasheet is linked in the Additional Information section below. Security Wholesalers stocks the DS-2CD2087G2H-LIU/SL and both the 2.8mm and 4mm lens variants are available.
