Introduction: Meet the Hikvision 4MP ColorVu Smart Hybrid Light Turret IP Camera (DS-2CD2347G3-LI2UY)
The Hikvision DS-2CD2347G3-LI2UY is a purpose-built turret IP camera designed for those who need reliable, high-quality 24/7 colour surveillance. Combining a 4 MP (2688 × 1520) sensor with Hikvisions ColourVu 3.0 imaging and an F1.0 fixed lens, this camera delivers vivid daytime-like colour in near-dark conditions. Its Smart Hybrid Light (selectable white light + IR) gives installers the flexibility to choose continuous full-colour monitoring or traditional IR night vision. Add in on-board deep-learning analytics for person/vehicle classification, dual microphones for two-way audio, robust outdoor protection (IP67/NEMA 4X) and multiple storage/networking options, and you have a highly capable turret camera for a wide range of deployments.

Detailed specifications and benefits
The DS-2CD2347G3-LI2UY uses a 1/1.8" progressive CMOS sensor to deliver 4 MP resolution (2688d71520) and a Main Stream of up to 25/30 fps. With an F1.0 fixed lens (available in 2.8 mm or 4 mm), the camera gathers significantly more light than typical surveillance lenses, which is central to producing accurate colour in low-light environments. Minimum illumination is rated at 0.0001 Lux in colour mode and 0 Lux when white light is active, meaning the unit can provide full-colour video in scenes that would be nearly pitch black for conventional cameras.
Smart Hybrid Light integrates both white light and IR LEDs in a single module. This gives two practical modes: continuous or on-demand white-light illumination to produce full-colour footage at night, or IR mode for covert night vision. Illumination range is up to about 30 m depending on the model and settings. The selectable approach balances image clarity, deterrence, and privacy concerns: white light improves identification and scene context, while IR keeps the scene discreet.
Video is encoded using H.265/H.264 family codecs with multi-stream support (main/sub/third) and features such as ROI and SVC. Bit rates are adjustable from 32 Kbps to 8 Mbps to help manage bandwidth. Perhaps more critical for modern security systems, the camera embeds deep-learning analytics for person and vehicle classification, face capture, and perimeter protection events (line crossing, intrusion, region enter/exit). These analytics reduce false positives and make alerts more actionable for security teams.
The DS-2CD2347G3-LI2UY includes a dual-microphone array for improved audio pickup and supports two-way audio. Audio codecs supported include G.711, G.722.1, AAC-LC and MP3. For storage, the unit accepts microSD cards up to 512 GB (card not included) and can connect to NAS using NFS or SMB/CIFS. Network compatibility is broad: ONVIF Profile S/G/T, HTTPS/TLS and 802.1X among others, enabling integration with many VMS platforms and network environments.
Power can be supplied via 12 VDC or PoE (IEEE 802.3af/at depending on variant), simplifying installations in many sites. The cameras metal housing is rated IP67 with anti-corrosion NEMA 4X properties for coastal and harsh environments. Operating temperature spans 6 C to 60 C, making the unit suitable for a wide variety of climates and outdoor locations.
Primary benefits summarized
- Superior low-light colour: F1.0 aperture + ColourVu means more useful facial and object detail in night scenes.
- Flexible night modes with hybrid lighting for either deterrence or discretion.
- Lowers false alarms and delivers smarter alerts thanks to embedded deep-learning analytics.
- Two-way audio for situational confirmation or deterrence without additional hardware.
- Durable outdoor build and network features that make the camera easy to integrate and maintain.
Use cases and scenarios where this camera excels
Entrances, perimeters and gates benefit from ColourVus ability to capture colour details at nightuseful for identifying clothing colours, vehicle paint and other cues that help investigations. The hybrid light also acts as a deterrent when set to active white-light mode.
For apartment entries, driveways and communal outdoor spaces, the DS-2CD2347G3-LI2UY provides clear evidence-grade colour video that helps property managers and residents quickly assess security incidents. Onboard analytics can be tuned to reduce nuisance alerts from small animals or environmental motion.
Retail exteriors, loading docks and storefronts gain from round-the-clock colour imaging to aid loss-prevention and incident reconstruction. Two-way audio lets staff warn off loiterers or coordinate with security remotely.
Person/vehicle classification improves event relevance in vehicle-rich scenes. Coupled with the wide field of view options (111 for 2.8 mm, 95.2 for 4 mm), the camera can monitor lanes, parking aisles and checkpoints with a single device.
How it compares to similar products
When evaluating the DS-2CD2347G3-LI2UY, consider three comparison angles: traditional IR cameras, competing full-colour low-light cameras, and other Hikvision ColorVu models.
IR-only units produce monochrome images at night, which makes it harder to identify colours and context. The DS-2CD2347G3-LI2UYs ColourVu 3.0 and F1.0 optics deliver full-colour imaging in much lower light levels, improving identification and situational awareness. IR mode remains available for covert surveillance.
Several manufacturers offer low-light colour products. The differentiators for this Hikvision model are the combination of the F1.0 aperture, Smart Hybrid Light, and built-in deep-learning analytics. Competitive models may match one or two of these aspects, but the balance of image quality, illumination flexibility and analytics is a strength here—especially for installers who want fewer add-on devices (separate illuminators, analytics servers, etc.).
Within Hikvisions ColorVu lineup, turret models like the DS-2CD2347G3-LI2UY offer a compact form and integrated lighting compared with bullet or dome variants. The 4 MP resolution is an attractive middle ground: higher detail than 2 MP models but with lower bandwidth and storage needs than some 6/8 MP options. Choose the DS-2CD2347G3-LI2UY when you want that balance of clarity, low-light colour and a compact outdoor housing.
Customer impressions and installer feedback
While individual reviews will vary by installation and configuration, common themes emerge from installers and end-users who choose ColourVu-equipped cameras like the DS-2CD2347G3-LI2UY:
- "Improved night identification" Installers frequently note that clients are surprised by the amount of colour retained in low-light scenes when white light is used.
- "Fewer false alarms" The person/vehicle classification reduces time wasted responding to irrelevant alerts compared with basic motion detection.
- "Easy integration" ONVIF support and common audio/video codecs make the camera straightforward to integrate into existing VMS and NVR systems.
- "Built for outdoors" The metal housing and IP67/NEMA 4X ratings give confidence in harsh or coastal deployments.
Note: above feedback reflects typical installer and user experiences with ColourVu and hybrid-light devices rather than verbatim published reviews for every deployment.
Considerations and best practices
To get the best results from the DS-2CD2347G3-LI2UY, plan illumination strategy, placement and analytics tuning in advance. If privacy or local illumination regulations are a concern, use the IR-only mode or configure white-light activation rules. Ensure PoE or 12 VDC power availability and follow local installation codes; network hardening (HTTPS/TLS, strong passwords, firmware updates) is essential on any IP camera deployment.
Conclusion: Why the DS-2CD2347G3-LI2UY is a strong choice
The Hikvision DS-2CD2347G3-LI2UY brings together high-sensitivity optics (F1.0), ColourVu 3.0 imaging, hybrid lighting and embedded deep-learning analytics in a compact, weatherproof turret design. For sites that need reliable, actionable colour video around the clock—entrances, perimeters, parking areas and residential properties—this camera offers a compelling mix of image quality, flexibility and value. Its integration-friendly feature set (ONVIF, multiple codecs, microSD/NAS) and audio capability further broaden its usefulness for modern security systems.
Whether your priority is clearer night-time identification, lower false-alarm rates through analytics, or a durable outdoor camera that simplifies installation, the DS-2CD2347G3-LI2UY is worth evaluating. Consider it when you want full-colour context in low light without sacrificing the benefits of traditional IR and modern AI-powered analytics.
