4MP ColorVu Fixed Turret Camera, 2.8 mm F1.0, AI, PoE DS-2CD2347G3-LI2UY

Introduction: Meet the 4MP ColorVu Fixed Turret Camera (DS-2CD2347G3-LI2UY)

The DS-2CD2347G3-LI2UY is a 4MP IP network turret camera designed for continuous full‑colour imaging in low‑light conditions. Built around ColorVu 3.0 technology, a large 1/1.8" progressive CMOS sensor and an F1.0 2.8 mm lens, it delivers vivid colour detail at night and daytime clarity for perimeter, retail, parking and general surveillance applications. Integrated smart hybrid lighting (white light + IR), on‑board AI for person/vehicle classification and PoE power make this model a practical, modern choice for sites that need reliable colour footage and reduced false alarms.

Detailed specifications and benefits

Understanding the technical highlights helps explain how this camera performs in real environments. The DS-2CD2347G3-LI2UY combines sensor, optics, illumination and analytics to solve common surveillance challenges.

• Sensor and resolution:A 1/1.8" progressive‑scan CMOS sensor delivers 4 MP (2688 × 1520) resolution at up to 30 fps. The larger sensor size improves light gathering over typical 1/2.8" sensors, yielding cleaner, higher‑detail images.
• Lens:The fixed 2.8 mm F1.0 lens produces a wide field of view (≈ 111.1°). The bright F1.0 aperture allows more light to the sensor, improving performance in dim scenes without relying entirely on artificial illumination.
• Low‑light performance:ColorVu 3.0 provides continuous full‑colour imaging down to 0.0001 Lux (with AGC) and captures colour in complete darkness when the built‑in white light is used. This is particularly valuable when colour details such as clothing, vehicle paint or signage matter for identification.

• Smart hybrid light:Integrated white LEDs plus IR (850 nm) enable selectable lighting modes—colour-first, IR‑only or hybrid—so the camera can prioritise colour detail while still offering discrete IR when needed.
• Range:Effective illumination is rated to roughly 30 m, sufficient for many perimeter and parking applications.

• Person & vehicle classification:On‑board AI separates human and vehicle targets from other motion, significantly cutting false positives from wind, foliage or small animals.
• Perimeter protection:Built‑in line crossing and intrusion detection can trigger alarms, capture snapshots and integrate with VMS/NVR systems for proactive monitoring.

• Compression & streaming:H.265/H.264 support with multiple streams optimises bandwidth and storage while preserving detail where needed.
• Local & network storage:microSD up to 512 GB plus NAS support (NFS, SMB/CIFS) and ANR for recording during network outages.
• Network security:ONVIF Profiles S/G/T for integration, plus HTTPS, TLS 1.1/1.2/1.3 and 802.1X for secure deployments.
• Power:PoE simplifies cabling and installation; a 12 VDC option is available. Typical power draw is low (Class 3 PoE, max ≈11 W).

• Ingress protection:IP67 and NEMA 4X anti‑corrosion rating make this camera suitable for harsh outdoor environments.
• Operating range:−30 °C to 60 °C covers most climates; correct mounting and sealing are essential to maintain the IP rating.

Use cases and scenarios where the camera excels

The DS-2CD2347G3-LI2UY is versatile and excels in environments where colour at night and accurate target filtering matter. Typical deployments include:

• Perimeter security:Wide‑angle coverage plus hybrid lighting and AI classification make it easier to detect and validate intrusions while minimising nuisance alarms caused by animals or debris.
• Retail loss prevention:Continuous colour detail in low light helps identify suspects, track merchandise and support investigations with clear visual evidence.
• Car parks and vehicle areas:Colour footage at night enables better licence plate and vehicle colour recognition when combined with appropriate placement and IR/white light settings.
• Building exteriors and entrances:The turret form factor and wide field of view are well suited to monitor doorways, loading bays and site approaches for safety and access control events.
• General‑purpose CCTV:Municipal, campus and industrial sites benefit from the camera’s robust environmental ratings and flexible analytics.

How it compares to similar cameras on the market

When evaluating this model, compare it across three axes: low‑light colour capability, analytics and total cost of ownership.

Traditional IR cameras switch to monochrome at night, losing colour information. The ColorVu approach preserves colour down to extremely low lux levels and can use white light to capture colour in total darkness. For scenes where colour (vehicle paint, clothing, signage) aids identification, ColorVu offers a significant evidence advantage over IR‑only units.

Compared with cameras using smaller sensors or slower lenses, the large 1/1.8" sensor and F1.0 aperture deliver better signal‑to‑noise ratio and shallower depth of field when needed. This translates to clearer images in dimly lit scenes without cranking up gain and adding noise.

Many lower‑cost cameras only support motion‑based triggers, which generate many false alarms. The DS-2CD2347G3-LI2UY’s person/vehicle classification reduces unnecessary alerts and can prioritise events that matter, lowering monitoring costs and improving operational efficiency.

Turret cameras are compact and easier to aim than many domes and some bullets, while offering similar weather resistance. The integrated hybrid light removes the need for separate illuminators in many installations, simplifying design and lowering overall system cost.

Conclusion: Why this camera is a strong choice

The DS-2CD2347G3-LI2UY blends powerful low‑light colour imaging, bright optics, hybrid illumination and practical AI analytics into a compact, weatherproof turret package. Its strengths include superior nighttime colour detail (thanks to ColorVu 3.0 and an F1.0 lens), meaningful false‑alarm reduction through person/vehicle classification, and flexible deployment options with PoE, local and network storage and robust cybersecurity features.

For organisations that need reliable 24/7 visual evidence—retailers, property managers, parking operators and perimeter security teams—this camera offers a compelling balance of performance and cost.

Next steps:For installers and buyers, request the datasheet and quick start guide, test the camera in representative lighting conditions, and verify mounting and sealing procedures to preserve IP67/NEMA ratings. Confirm any needed certifications for your region and engage an experienced installer to ensure optimal positioning and integration with your VMS or NVR.
