Hikvision DS-2CD2047G3-LI2UY 4 MP ColourVu Hybrid‑Light Mini Bullet (4 mm)

Introduction: Meet the Hikvision DS-2CD2047G3-LI2UY

The Hikvision DS-2CD2047G3-LI2UY is a compact yet capable 4 MP ColorVu hybrid‑light mini bullet camera engineered for round‑the‑clock colour imaging and active deterrence in outdoor environments. Combining a super‑aperture F1.0 4 mm lens, Smart Hybrid Light (white light + IR), onboard deep‑learning analytics (AcuSense), built‑in audio and active strobe/siren deterrents, PoE convenience and an IP67 metal housing, this camera targets sites that need dependable, high‑quality colour detail even in near‑darkness.

At a suggested price of $199 (cost price noted at $118.58 for reference), the DS-2CD2047G3-LI2UY packs advanced imaging and intelligent features common to higher‑end systems while remaining compact and easy to deploy. In short, it is marketed to installers and end users who want continuous colour monitoring plus tools for reducing false alarms and escalating incidents proactively.

Key features at a glance

• 4 MP resolution: 2688 × 1520 at 25/30 fps for clear, useful scene detail.

• Smart Hybrid Light: integrated white light and IR (850 nm) with selectable modes and supplementary range up to ~40 m.
• Onboard deep‑learning analytics (AcuSense): person/vehicle classification, perimeter protection, face capture to reduce false alarms.
• Active deterrence: built‑in dual microphone, audible siren and visual strobe for immediate on‑site deterrence.
• Rugged, outdoor ready: metal housing rated IP67 / NEMA 4X; PoE support (802.3af) and microSD storage up to 512 GB.

Detailed specifications and benefits

The camera uses a 1/1.8" progressive‑scan CMOS sensor delivering 4 MP resolution (2688 × 1520). The fixed 4 mm lens paired with an F1.0 super‑aperture lets more light reach the sensor, improving colour fidelity and detail in extremely low light. The field of view is wide (horizontal ≈ 95.2°) which is ideal for entrances, car parks and perimeter coverage without needing an extra‑wide lens.

Benefit: images maintain colour and usable detail where many standard cameras revert to monochrome or noisy footage. This helps with identification of people, clothing, vehicles and small scene details that matter for investigations.

ColorVu technology combined with the F1.0 aperture achieves colour imaging down to 0.0001 Lux with AGC enabled, and full‑colour 0 Lux when the integrated white light is active. The Smart Hybrid Light system integrates white light and IR illumination, selectable in multiple modes so the camera can provide purely IR, purely white light, or hybrid behaviours depending on incident detection and user preference. The supplementary illumination range can reach up to approximately 40 m depending on settings and environmental conditions.

Benefit: the selectable hybrid lighting lets you balance discreet monitoring (IR) with active colour illumination and deterrence (white light) exactly where and when it is needed.

Onboard deep‑learning analytics (AcuSense) provide person and vehicle classification, perimeter protection rules and face capture. These capabilities reduce nuisance alerts from trees, small animals and other environmental motion while flagging human and vehicle movements that matter. The camera supports up to three independent streams and image‑enhancement features such as WDR (130 dB), 3D DNR and defog.

Benefit: fewer false alarms and higher‑quality alerts enable faster responses and lower operational overhead for monitoring teams.

The DS-2CD2047G3-LI2UY includes a built‑in array dual‑microphone (model dependent) and supports two‑way audio on certain SKUs. Active deterrent outputs include an audible siren and visual strobe, which can be triggered locally by analytics or remotely via the management system. Local storage is supported via microSD/microSDHC/microSDXC up to 512 GB; NAS support with ANR is available for resilient recording.

Benefit: audio and active deterrence increase the chance of stopping incidents in progress, and local storage keeps footage safe during network interruptions.

Network protocols include ONVIF (S/G/T), HTTPS/TLS, 802.1X and Hikvision APIs; up to 32 users may be configured depending on system setup. Power options include 802.3af PoE (Class 3) and 12 VDC input. Typical power consumption is ≤ 4.8 W (12 VDC) and ≤ 6.5 W (PoE max). The metal housing, IP67/NEMA 4X ingress protection and operating temperature range (−30 °C to 60 °C) make the camera suitable for most challenging outdoor conditions.

Benefit: secure network support and flexible power options simplify installation, while a robust housing assures long‑term operation outdoors.

Use cases and scenarios where the camera excels

• Perimeter and fence line monitoring: wide field of view and ColorVu colour imaging capture identifying detail such as clothing colours and vehicle plates at night when colour information is critical.
• Car parks and loading yards: the hybrid‑light and analytics setup helps detect and classify people and vehicles while integrated deterrence can discourage loitering or theft.
• Retail and commercial entrances: face capture and person classification reduce false positives and support investigations or loss prevention workflows.
• Higher‑end residential sites: the compact bullet form factor, integrated deterrence and attractive price make it suitable for gated homes, small estates and property entrances.
• Remote or poorly lit locations: sites without existing lighting benefit from ColorVu’s ability to deliver usable colour images even before turning on white lights.

Comparisons with similar products on the market

When evaluating the DS-2CD2047G3-LI2UY it helps to compare it by capability categories rather than solely by brand. Three common camera types to consider are:

• Standard IR cameras: Many traditional outdoor bullets use IR illumination only and switch to monochrome at night. Compared to IR‑only models, the ColorVu hybrid approach preserves colour information and offers active white light deterrence, which can be decisive for identification and incident prevention.
• Low‑light (Starlight) cameras: Starlight‑type sensors emphasize sensitivity and can produce good results in near darkness with limited light. ColorVu’s distinguishing factor is the combination of a super‑aperture lens and integrated white light to deliver consistent colour, rather than relying on post‑processing or heavy gain that increases noise.
• Higher‑end 4K or multi‑sensor cameras: 4K models provide more pixels for zoomed‑in detail but are costlier and demand more storage/bandwidth. The 4 MP resolution in the DS-2CD2047G3-LI2UY strikes a pragmatic balance between detail and system resource requirements for many perimeter and entrance applications.

Comparatively, the Hikvision model’s strengths are its ColorVu F1.0 optics and hybrid lighting, combined with onboard deep‑learning analytics and active deterrence. If your priority is ultra‑high resolution or panoramic coverage, a 4K or multi‑sensor camera might be preferable. If your priority is continuous colour detail in low light with smart alerts and a compact form, this model is a very competitive choice.

Customer feedback and representative testimonials

Public, platform‑specific reviews for this exact SKU may vary by region and distributor. Representative customer feedback themes that commonly appear for ColorVu/AcuSense cameras like this include:

• "Colour at night changed how we investigate incidents — we can see clothing colours and car details without extra lighting."
• "AcuSense reduced nuisance alerts dramatically, so we only respond to real events."
• "Built‑in deterrence with strobe and siren stopped loiterers before they broke anything."
• "Compact form and PoE made installation fast and tidy, the image quality is better than expected for the price."

Note: These are illustrative, aggregated sentiments typical of users of ColorVu/AcuSense hybrid cameras and not direct quotes attributed to named individuals. For verified, site‑specific reviews check distributor pages, trade forums or installer testimonials in your region.

Practical considerations for installation and operation

To get the best results: choose correct mounting locations to maximise the field of view, configure Smart Hybrid Light modes to suit the environment (e.g., stealth IR at late hours, white light on detection), use PoE for simplified cabling, and enable secure network practices including strong passwords, HTTPS/TLS and timely firmware updates. For mission‑critical deployments, pair the camera with a properly configured NVR or VMS that supports AcuSense analytics and ONVIF for interoperability.
