Product Overview
Combining active deterrence with full-colour night imaging and motorised zoom flexibility, the DS-2CD3687G3-LIZSUY/SL is an 8MP 4K UHD outdoor bullet camera built for commercial perimeters, industrial yards, car parks, and high-risk building entrances where passive monitoring is not enough. Featuring DarkFighter 2.0 technology with a large F1.2 aperture and smart dual illumination across both IR and white-light LEDs up to 60m, this camera maintains strong visibility after dark without sacrificing colour detail. The motorised 2.7-13.5mm varifocal lens allows remote focal length adjustment to suit anything from wide approach coverage to focused entrance framing. It also integrates AI-powered person and vehicle classification, face capture, and people counting running on HEOP 2.0 edge processing. Built with IP67 weatherproofing, IK10 vandal resistance, and NEMA 4X anti-corrosion protection on the -Y variant, the DS-2CD3687G3-LIZSUY/SL is designed for demanding outdoor sites including coastal and industrial environments.
Key Capabilities
8MP 4K UHD Imaging
The 3840 x 2160 sensor captures fine detail across wide outdoor scenes, making it practical for identifying faces, licence plates, and objects at distance along perimeter fencing, loading areas, or building approaches.
Motorised Varifocal 2.7-13.5mm Lens
Remote lens adjustment from approximately 112° wide angle down to 41° telephoto lets installers frame a scene precisely after mounting without returning to the camera. This is particularly useful on elevated or hard-to-reach outdoor wall positions.
DarkFighter 2.0 with F1.2 Aperture
The large F1.2 aperture pulls significantly more light than standard lenses, giving the camera strong colour performance under low ambient light. DarkFighter 2.0 processing further improves colour rendering in near-dark outdoor conditions.
Smart Dual Illumination up to 60m
Built-in IR and white-light LEDs provide up to 60m of supplemental illumination. White-light mode delivers full-colour night footage for identification. IR mode extends range discreetly and in full darkness, with the camera switching modes based on scene conditions.
Active Deterrence with Strobe and Two-Way Audio
The built-in strobe light, loudspeaker, and microphone allow the camera to issue visible and audible warnings when a trigger is detected. Two-way audio enables real-time voice communication, supporting active intervention from a monitoring station.
AI Analytics on HEOP 2.0 Edge Processor
Running at 1.5 TOPS, the onboard HEOP 2.0 processor handles person and vehicle classification, face capture, and people counting locally. This reduces network load and produces more meaningful event triggers than basic motion detection.
Best For
- Commercial and Industrial Perimeters: The motorised 2.7-13.5mm lens and 60m dual illumination make this camera well suited to monitoring fence lines, yard entries, and wide outdoor approaches at warehouses and industrial facilities.
- Car Parks and Loading Docks: 8MP resolution combined with AI vehicle classification supports number plate and incident review in car parks, while the strobe and loudspeaker can deter after-hours activity in real time.
- Building Entrances and High-Risk Access Points: Face capture and person classification provide structured event data at entry points, while two-way audio allows direct communication with individuals approaching a site.
- Coastal and Harsh-Environment Sites: The -Y variant with NEMA 4X anti-corrosion protection extends the camera’s usable life in salt air, chemical exposure, or aggressive industrial environments alongside its IP67 and IK10 ratings.
- Remote and Unmanned Sites: HEOP 2.0 edge processing and active deterrence allow the camera to respond to intrusion events autonomously, reducing reliance on constant live monitoring at unmanned facilities.
Why Choose the DS-2CD3687G3-LIZSUY/SL
The DS-2CD3687G3-LIZSUY/SL is one of the few 8MP outdoor bullet cameras that combines a motorised varifocal lens, DarkFighter 2.0 low-light imaging, smart dual illumination, active deterrence, and onboard AI analytics in a single ruggedised housing. A simpler fixed-lens bullet will not give you remote focal adjustment after installation. A camera without DarkFighter 2.0 and the F1.2 aperture will produce noticeably weaker colour performance in partially lit outdoor areas. The active deterrence package, including strobe light, built-in loudspeaker, built-in microphone, and two-way audio, removes the need to install a separate audio device at the same location. The HEOP 2.0 processor at 1.5 TOPS handles person classification, face capture, and people counting at the edge, which simplifies downstream NVR processing requirements. Available at Security Wholesalers, the DS-2CD3687G3-LIZSUY/SL suits installers and site managers who need a single camera to carry both surveillance and active response capability in one outdoor-rated unit.
Buyer Decision Tips
Varifocal Lens Adjustment: The motorised 2.7-13.5mm lens covers a horizontal field of view from approximately 112° down to 41°. For a typical warehouse entry or car park approach, start with a wider setting to establish scene context, then tighten remotely via your NVR or VMS without needing a ladder. If your target scene requires coverage beyond this zoom range, a camera with a longer fixed telephoto lens may be more appropriate.
Variant Selection – Standard vs -Y: If the camera will be installed within 1km of coastline, near a chemical processing area, or in a high-humidity industrial environment, specify the -Y variant to gain NEMA 4X anti-corrosion protection. The standard variant carries IP67 and IK10 but does not include the anti-corrosion treatment on housing materials.

Ideal Use Cases
Warehouse Perimeters
The motorised 2.7-13.5mm lens can be tightened to monitor a specific gate or entry point from a distant wall mount, while the strobe and loudspeaker deter after-hours access without requiring security personnel on site.
Car Parks and Exposed Vehicle Areas
AI vehicle classification generates targeted event alerts in high-vehicle-traffic areas. Full-colour night imaging via white-light LEDs at up to 60m supports after-dark footage review at a level of detail that IR-only cameras cannot match.
Industrial and Manufacturing Sites
IP67 weatherproofing, IK10 impact resistance, and NEMA 4X protection on the -Y variant make the DS-2CD3687G3-LIZSUY/SL a practical fit for factories, processing plants, and yards where chemical exposure or physical hazards are present.
Building Entrances and Security Checkpoints
Face capture and person classification record structured metadata at access points. Two-way audio enables voice contact with individuals before they enter a building, supporting intercom-style interaction from a central monitoring position.
Coastal and Marine Environments
The -Y variant’s NEMA 4X anti-corrosion treatment addresses accelerated housing degradation from salt air and sea spray. Combined with IP67 and IK10, this makes the camera usable in port facilities, marinas, and coastal commercial properties.
Remote and Unmanned Facilities
HEOP 2.0 onboard processing and active deterrence allow the camera to classify events and trigger audio-visual warnings autonomously. People counting provides occupancy data useful for sites managed remotely without constant live operator attention.
Choosing the Right Model
- Choose this model if: You need an outdoor bullet camera with motorised zoom for post-installation framing adjustments, full-colour low-light imaging via DarkFighter 2.0 and white-light LEDs, onboard AI for person and vehicle classification, and an integrated active deterrence package including strobe, loudspeaker, and two-way audio in a single IP67/IK10 housing.
- Choose a different model if: Your installation requires a fixed wide-angle lens for a tight indoor ceiling position where a motorised varifocal bullet adds unnecessary cost. A dome or turret form factor would be better suited to indoor ceiling mounting where the bullet sun visor and directional housing profile are not needed.
- Choose the -Y variant if: The installation site is within coastal proximity, involves chemical or industrial air exposure, or requires NEMA 4X anti-corrosion protection on the housing materials. The standard variant does not include this treatment.
FAQs
- What is the difference between the standard model and the -Y variant?
The -Y variant adds NEMA 4X anti-corrosion protection to the housing materials on top of the standard IP67 and IK10 ratings. This is specifically relevant for installations near coastlines, in marine environments, or at industrial sites with chemical air contamination. If your site does not involve these conditions, the standard variant provides sufficient environmental protection.
- Can the motorised lens be adjusted after the camera is installed on the wall?
Yes. The 2.7-13.5mm motorised varifocal lens can be adjusted remotely via a compatible Hikvision NVR or VMS without physically accessing the camera. This allows installers to fine-tune the horizontal field of view from approximately 112° wide to 41° telephoto after the camera is fixed in place, which reduces installation time significantly on elevated or difficult-to-reach mounting positions.
- Does this camera produce colour footage at night or only black and white?
The DS-2CD3687G3-LIZSUY/SL uses smart dual illumination with both white-light and IR LEDs. When white-light mode is active, the camera delivers full-colour night footage up to approximately 60m. In IR mode it produces monochrome footage at the same range. The F1.2 aperture and DarkFighter 2.0 technology also improve colour rendering under ambient low-light conditions before supplemental illumination activates.
- How does the active deterrence system work?
When the camera detects a qualifying event, the built-in strobe light activates and the loudspeaker can issue an audible warning or pre-recorded message. Two-way audio allows a monitoring operator to speak directly through the camera’s speaker in real time. These functions can be configured to trigger on person or vehicle detection events processed by the onboard AI, reducing unnecessary activations from irrelevant motion.
- What AI functions are available on this camera?
The HEOP 2.0 processor at 1.5 TOPS supports person and vehicle classification, face capture, and people counting. These run on the camera itself rather than relying on the NVR for processing. This reduces false event triggers compared to basic motion detection and provides structured metadata that can be searched and filtered in Hikvision management platforms.
- Is this camera suitable for mounting on a pole rather than a wall?
Yes. The bullet housing includes a standard mounting bracket, and Hikvision compatible pole mount brackets are available separately to suit vertical pole installations. Pole mounting can be appropriate for car parks or open outdoor areas where wall or eave mounting is not practical. Security Wholesalers stocks compatible Hikvision pole brackets for this camera.
- What resolution and frame rate does this camera operate at?
The camera captures at 8MP (3840 x 2160) 4K UHD resolution. Refer to the Hikvision datasheet for confirmed frame rate specifications at each resolution setting, as these can vary depending on stream configuration and connected NVR capability.
