Introduction to the Hikvision 4MP ColorVu Turret and its key features
Hikvision DS-2CD2347G3-LIS2UY/SLis a Pro‑series fixed‑turret surveillance camera that brings advanced low‑light colour imaging, onboard audio, and deep‑learning analytics into a compact outdoor housing. At its core it combines a large 1/1.8" progressive‑scan CMOS sensor with Hikvisions ColorVu 3.0 technology and Smart Hybrid Light (an intelligent combination of IR and white light). The camera delivers 4 MP (2688 × 1520) resolution at up to 25/30 fps through a fixed 2.8 mm lens, and supports PoE (IEEE 802.3at) or 12 VDC power. Key hardware highlights include a built‑in dual microphone array, integrated speaker/siren for two‑way audio and audible deterrence, on‑board microSD storage up to 512 GB, and IP67 / NEMA 4X weather resistance.
Detailed description of specifications and benefits
The DS-2CD2347G3 uses a 1/1.8" progressive CMOS sensor and a bright F1.0 aperture to capture more light per pixel. Combined with ColorVu 3.0 and Smart Hybrid Light, it produces vivid colour images in extremely low light (Colour 0.0001 Lux @ F1.0 with AGC on) and delivers usable, full‑colour video even when human‑visible light is minimal. When required, the integrated white light can illuminate a scene to achieve 0 Lux colour imaging. For security applications where identifying clothing colour, vehicle paint, or scene context at night matters, this camera provides a significant advantage over conventional IR‑only systems.
The fixed 2.8 mm lens gives an approximately 111B0 horizontal field of view, making the turret well suited to medium‑range area coverage such as parking lots, store fronts, loading bays, and property perimeters. A 4 mm variant is available for slightly narrower, longer‑range coverage. The turret form factor is compact and easy to mount under eaves, on walls or ceiling brackets, and the IP67 / NEMA 4X corrosion‑resistant housing makes it suitable for outdoor exposure in harsh environments.
Video is delivered at 4 MP resolution with frame rates up to 25/30 fps and supports modern codecs including H.265/H.265+, H.264/H.264+ for efficient storage and streaming. The camera offers scene‑adaptive 130 dB WDR, 3D DNR for low noise, BLC/HLC, defog and distortion correction to improve image clarity in challenging lighting. Standard protocols such as ONVIF, HTTPS and RTSP allow easy integration with many NVRs and VMS platforms.
Built‑in arrayed dual microphones and a speaker enable two‑way audio and an integrated siren output (~2 W). This adds a deterrence layer: operators can speak to intruders or trigger a pre‑recorded warning tone. Audio codecs supported include G.711, G.726, MP3 and AAC‑LC depending on firmware and model variations. When using audio, installers and operators should follow local laws and notification requirements for recording sound.
Deep‑learning analytics are part of the feature set: person/vehicle classification, face capture and perimeter protection functions such as line crossing, intrusion detection and region entrance/exit. These analytics help reduce nuisance alerts caused by shadows, animals or foliage by focusing on human and vehicle objects—making monitoring and event review more efficient.
Storage options include on‑board microSD up to 512 GB, ANR to recover recordings if the network goes down, and NAS support through NFS or SMB/CIFS. Power can be supplied via PoE (IEEE 802.3at, Class 4) for simplified cabling, or 12 VDC where preferred. Typical power draw ranges up to roughly 12–16 W depending on features used. The camera operates from

Use cases and scenarios where this camera excels
The DS-2CD2347G3 is designed for situations where clear colour detail in low light matters, and where built‑in deterrence or audio interaction is beneficial. Typical deployments include:
- Retail storefronts and parking areas:Colour at night helps identify clothing and vehicle colours for investigations; audio can deter loiterers or intervene during an incident.
- Warehouse yards and loading docks:Broad field of view captures activity across gates, loading bays and vehicle movement; analytics reduce false alerts from non‑relevant motion.
- Perimeter and campus security:Line crossing and intrusion detection with person/vehicle classification sharpen alarm relevance for security teams monitoring long stretches of fence or walkways.
- Hospital, school and commercial properties:Night shift monitoring, staff safety and access control integration are enhanced with face capture and two‑way audio for coordination or deterrence.
- Residential and gated communities:Weather resistance, wide FOV and low‑light colour make it a strong option for community entrance points and common areas.
Comparisons with similar products on the market
In the current market, low‑light colour and hybrid illumination cameras are offered by several manufacturers. Heres how the Hikvision ColorVu turret compares in broad terms:
Compared to smaller‑sensor ColorVu models, the DS-2CD2347G3s 1/1.8B4 sensor and F1.0 optics deliver better light‑gathering, improved dynamic range and more detailed 4 MP imagery. It holds the advantage of integrated audio and deeper analytics in a compact turret form—features sometimes reserved for higher‑end bullets or domes.
Competing technologies such as Dahuas Starlight or Axiss Lightfinder focus on very low lux black‑and‑white imaging with high sensitivity. ColorVus differentiator is full‑colour imaging at extremely low illuminance and the option to use white light for identifying details—this can be more useful when colour is essential for investigations. Trade‑offs include slightly higher visible intrusion (white light) when used and different proprietary processing behaviors that buyers should evaluate via side‑by‑side tests.
With a suggested price around $179.99, the DS-2CD2347G3 is positioned as a mid‑range, feature‑rich camera. It competes well on value considering 4 MP resolution, onboard analytics, audio, robust weather rating and PoE. Higher‑end models from enterprise brands may offer marginally better low‑light pixel performance or additional warranty options at a higher price point; lower‑cost cameras may lack the analytics, audio hardware or industrial weather ratings.
Customer feedback and reviewer impressions
There are no official customer testimonials provided here, but common themes reported by installers and end users of similar Hikvision ColorVu devices include:
