• Deep‑learning analytics:Person/vehicle classification, face capture and perimeter protection (line crossing, intrusion).
• Integrated audio and alarm:Dual array microphones, two‑way audio via built‑in speaker, and audio/strobe/siren alarm output.
• Flexible recording and compression:H.265/H.264 codecs, ONVIF support, PoE+ (IEEE 802.3at) and local microSD up to 512 GB.
• Rugged outdoor build:Metal housing rated IP67 and NEMA 4X for harsh environments.

Detailed specifications and benefits

The DS-2CD2347G3-LIS2UY/SL uses a 1/1.8" progressive CMOS sensor to deliver a maximum resolution of 26881520 (4 MP). The 4 mm fixed lens yields a wide horizontal field of view of approximately 95.2, making it well suited to entranceways, retail aisles and car park surveillance where a wider scene must be covered without multiple cameras. With a DORI range of Detect 75 m / Observe 30 m / Recognise 15 m / Identify 7 m (for the 4 mm lens), it provides practical situational awareness across medium to near ranges.

Where this camera stands out is in low‑light performance. The ColorVu system, combined with Smart Hybrid Light (white light + IR), produces full‑colour images down to extremely low lux levels (listed minimum illumination is 0.0001 Lux @ F1.0, and 0 Lux when the light is active). The hybrid illumination provides flexible, scene‑adaptive lighting: white light for colour evidence and IR for discreet monitoring, with an effective illumination range up to about 30 m under smart control.

Hikvision equips the camera with modern encoding options (H.265, H.264 and enhanced variants) to reduce bandwidth and storage requirements without sacrificing image quality. It supports frame rates up to 25 fps @50 Hz (30 fps @60 Hz) at full 4 MP resolution and a variable bitrate from 32 Kbps to 8 Mbps, allowing administrators to tune quality vs. network load.

Image enhancement tools include 130 dB WDR (useful in scenes with bright backlighting), 3D DNR for noise reduction, EIS for stabilization, defog and distortion correction. For local resilience, the device accepts microSD/microSDHC/microSDXC cards up to 512 GB and can also integrate with NAS (NFS / SMB / CIFS) while supporting ANR for recording continuity during network issues.

On the analytics front, the camera uses deep‑learning algorithms to classify human and vehicle targets, perform face capture, and enforce perimeter rules like line crossing and intrusion detection. This reduces false alarms and focuses operator attention on meaningful events.
The built‑in dual array microphone and two‑way audio (plus a 2 W speaker capable of generating up to 110 dB SPL at 10 cm) enable onsite voice announcements, deterrence messages or interaction with visitors. Combined with the audible/visual alarm (siren and strobe), it forms an effective active‑response tool for perimeter security or retail loss prevention.

Network connectivity is standard RJ45 10/100 Mbps with ONVIF Profiles S/G/T for integration with third‑party NVRs and VMS platforms that adhere to the standard. Power options include PoE+ (IEEE 802.3at, Class 4) and 12 VDC input; power draw is modest (max about 17 W via PoE), simplifying cabling and installation for many deployments.

The cameras metal housing and ingress protection (IP67 and NEMA 4X) make it suitable for exposed outdoor applications, resisting dust, water and splashes, while operating across a wide temperature range (30 °C to 60 °C). Installers should follow Hikvisions official guidelines for mounting, wiring and surge protection to ensure long service life.

Use cases and scenarios where this camera excels

• Perimeter and site surveillance:The combination of long detection ranges, ColourVu illumination and audible alarms makes the camera effective at both detecting and deterring intruders on fences, gates and site boundaries.
• Retail environments:Bright colour images at night help preserve evidential detail (clothing colours, vehicle paint), plus analytics and audio warnings support loss prevention programmes.
• Car parks and access points:Wide field of view and face/vehicle classification make it suitable for monitoring entrances and exits, with colour imaging improving description accuracy in investigations.
• Entrance monitoring:Two‑way audio and face capture are useful for concierge applications and controlled access points where interaction and identity documentation are required.
• Municipal and critical infrastructure:Robust environmental ratings and advanced analytics are advantageous for public spaces, transit hubs and small critical facilities requiring reliable 24/7 surveillance.

How it compares with similar cameras on the market

Within Hikvisions own lineup, the DS-2CD2347G3-LIS2UY/SL sits as a mid‑to‑high capability turret option focused on low‑light colour performance. Compared to basic day/night dome cameras that rely solely on IR, this ColorVu model delivers richer forensic value after dark because of colour retention. Against older Hikvision models without hybrid light or deep‑learning analytics, the G3 series provides improved classification accuracy and reduced false alarms.

Against competing brands (for example, Dahuas Color technology or other manufacturers offering supplementary white light), the differences often come down to implementation: sensitivity of the sensor, quality of the optics, tuning of analytics and the robustness of audio/alarm functions. Dahua and other vendors offer similar full‑colour options, but Hikvisions mature ColorVu ecosystem and broad ONVIF support make integration with existing NVRs and management platforms straightforward.

Where budget is the primary constraint, lower cost fixed‑lens cameras without hybrid lighting may suffice, but they sacrifice night‑time colour evidence. Conversely, higher‑end multi‑sensor panoramic units offer broader coverage but at greater cost and complexity. The DS-2CD2347G3-LIS2UY/SL strikes a balance: wide FOV, strong low‑light colour imaging and useful on‑device intelligence at a competitive price point for many applications.

Customer feedback and typical reviewer comments

While individual experiences vary, common positive feedback from installers and end users typically includes praise for the cameras night‑time colour reproduction, ease of PoE deployment and the clarity of audio when used for two‑way communication. Installers often note the solid metal housing and clear documentation, and system integrators appreciate ONVIF compatibility for multi‑vendor systems.

Some users mention configuration nuances—tuning illumination thresholds and analytics sensitivity to reduce nuisance alerts—so allowing a brief commissioning period to adjust settings is advisable. As with many feature‑rich cameras, maximizing value requires familiarisation with the cameras interface and the VMS/NVR settings it integrates with.

Conclusion: why this camera is a strong choice

The Hikvision DS-2CD2347G3-LIS2UY/SL is a versatile turret camera that addresses a common and growing requirement: reliable, full‑colour surveillance in low‑light conditions. Its ColorVu technology, Smart Hybrid Light and deep‑learning analytics provide both evidential quality and event prioritisation, while integrated audio and audible/visual alarm features enable active deterrence and interaction without additional peripherals.

With robust outdoor ratings (IP67 / NEMA 4X), flexible power via PoE+, and support for local and networked recording, it suits a range of applications from retail and entrances to perimeters and municipal installations. For projects demanding clear night‑time colour detail and actionable analytics at a reasonable price, this Hikvision 4 MP ColorVu turret camera is a compelling option. As always, confirm warranty, compliance and installation procedures with your supplier or the manufacturer and plan for appropriate mounting and surge protection for long‑term reliability.
