Detailed specifications and benefits
Under the hood the DS-2CD2047G3-LI2UY/SL packs professional‑grade hardware and software that translate into better image quality, smarter alerts and easier deployment.
- Sensor & resolution:A 1/1.8" progressive scan CMOS sensor drives a 4 MP (2688 × 1520) image at up to 25/30 fps, delivering the resolution needed for licence plates, faces and other details in many surveillance scenarios.
- F1.0 super‑aperture lens:The exceptionally wide F1.0 aperture lets more light reach the sensor. Combined with Hikvisions ColorVu hybrid light (white + IR), the camera can produce full‑colour images in extremely low ambient light (colour to 0.0001 Lux) and use white light to illuminate scenes at night up to about 40 m.
- Fixed focal options:Available in 2.8 mm (H ≈111) or 4 mm (H ≈95) focal lengths to suit wide‑area coverage or slightly narrower fields of view where more detail is needed.
- Efficient codecs:Support for H.265 and H.264 (and their enhanced + variants) reduces bandwidth and storage without sacrificing image quality.
- Smart streams:Multiple streams and ROI support let you optimise remote viewing and recording for critical areas.
- Deep‑learning analytics:Person/vehicle classification reduces false alarms from animals or foliage. Face capture, perimeter protection (line crossing, intrusion, region enter/exit) and motion detection make the camera suitable for automated event workflows and smarter alerting.
- Integrated audio:Arrayed dual microphone and a built‑in speaker (up to 2 W) enable two‑way communication and audible warnings. This is useful for remotely addressing intruders or interacting with visitors.
- Active deterrence:The cameras programmable strobe and white‑light output, combined with audio warnings, provide an immediate, visible and audible deterrent to intruders — often more effective than passive recording alone.
- Local storage:microSD support up to 512 GB plus ANR for buffering during network outages, and NAS support (NFS/SMB/CIFS) for flexible recording architectures.
- Power options:PoE+ (IEEE 802.3at, Class 4, max 16 W) simplifies cabling and supports remote power over Ethernet, or use 12 VDC where PoE is not available (max ~12 W typical consumption).
- Rugged housing:Metal build with IP67 ingress protection and NEMA 4X anti‑corrosion rating withstands rain, dust and corrosive environments. Operating temperature range from 10 C to 60 C (note: the spec lists ; check local datasheet for exact figures) ensures suitability for many climates.
- Form factor:A compact mini‑bullet design (Ø74.4 × 176.3 mm, ~530 g) makes mounting discreet yet durable on walls or ceilings.
Use cases and scenarios where this camera excels
The DS-2CD2047G3-LI2UY/SLs feature set makes it a versatile choice across several common security scenarios:
For commercial properties, warehouses or residential perimeters, the cameras colour night imaging and active deterrence are invaluable. The ability to capture colour detail at night improves identification, while the strobe and audio warn off intruders before escalation.
Retail locations benefit from the cameras face capture and person/vehicle classification. Colour night footage helps identify individuals and vehicles involved in after‑hours incidents, and two‑way audio lets staff or remote operators deter loiterers or handle deliveries.
Wide coverage options and clear night imaging are ideal for parking lots and access lanes. The cameras deep‑learning analytics can reduce false alarms from moving vegetation or stray animals, focusing alerts on vehicles and people.
PoE+ support simplifies deployment to sites where single‑cable solutions are preferred. The robust housing helps cameras endure harsh outdoor conditions and vandalism threats common at such locations.
Comparisons with similar products on the market
When choosing an outdoor mini‑bullet camera, buyers typically weigh imaging performance, analytics capability, deterrence features and environmental toughness. Heres how the Hikvision DS-2CD2047G3-LI2UY/SL compares in general terms:
- Versus IR‑only cameras:Traditional day/night cameras that rely solely on IR illumination produce monochrome night images; the ColorVu hybrid light + F1.0 aperture delivers full‑colour night images with superior detail for recognition tasks. Colour footage often yields better situational understanding (clothing, cars, signage).
- Versus similar ColorVu class devices:Within Hikvisions ColorVu lineup and comparable offerings from other vendors, this model stands out for combining an F1.0 aperture with active deterrence (strobe + speaker) and deep‑learning analytics in a compact, weatherproof housing — a strong balance of image quality and smart features for its price band.
- Versus higher‑end multi‑sensor or PTZ solutions:Multi‑sensor and PTZ cameras can cover larger areas or track targets, but at higher cost and complexity. The DS‑2CD2047G3 is optimized for fixed views where constant colour fidelity, analytics and deterrence are more valuable than remote pan/tilt/zoom capability.
Ultimately, its combination of F1.0 optics, ColorVu lighting, PoE+ and analytics make it a compelling mid‑range option for projects that need more than a basic IR camera but where enterprise multi‑sensor systems are unnecessary.
Customer feedback and installer observations
There are no direct, verifiable customer testimonials supplied here; however, common themes from installers and end users of similar ColorVu devices that are worth noting include:
- "Noticeably better colour at night" — Users often comment that ColorVu systems provide actionable colour images in low light where IR cameras give only grainy monochrome footage.
- "Active deterrence reduces incidents" — Sites that enable strobe and audible warnings report fewer repeat intrusions, as visible and audible interventions tend to drive offenders away quickly.
- "Easy PoE deployment" — Installers appreciate PoE+ power for single‑cable installation and remote power management, especially on sites with constrained cabling runs.
- "Analytics saves time" — Deep‑learning person/vehicle classification cuts down on false positives and reduces time spent reviewing irrelevant recordings.
When evaluating real‑world feedback, ask your supplier for references or demo footage from similar installations to validate expectations for night colour, deterrence effectiveness and analytics performance in environments like yours.
