Detailed description of specifications and benefits
At the heart of the DS-2CD2347G3-LIS2UY/SL is a 1/1.8" progressive-scan CMOS capable of producing 4 MP images (2688 1520). The relatively large sensor combined with an F1.0 aperture and ColorVu 3.0 delivers vibrant, full-colour images even in very low lighting conditions (colour sensitivity down to 0.0001 lux with AGC enabled). Where additional illumination is required, the Smart Hybrid Light system can provide selectable white-light or 850 nm IR supplement up to approximately 40 m depending on scene conditions.
AcuSense AI provides human/vehicle classification, perimeter detection (line crossing and intrusion zones) and face capture. This means the camera can prioritise alerts that matter and suppress nuisance notifications caused by animals, foliage or irrelevant motion. For sites where alarm fatigue is a concern, AcuSense can significantly improve operational efficiency.
The SL variant integrates an active deterrence system with a bright strobe (white light) and a built-in speaker capable of playing pre-recorded messages or live voice. Two-way audio is supported via dual-array microphones and the speaker, enabling operators to interact directly with subjects on siteuseful for retail loss prevention, access control points or perimeter warnings.
Video is efficiently encoded using H.265/H.264 (including + variants) and supports multiple streams, ROI and SVC for adaptive bandwidth management. Local recording is supported by microSD/microSDHC/microSDXC cards up to 512 GB (with ANR for network outage recovery) and network storage via NAS (NFS, SMB/CIFS). Network compatibility includes ONVIF Profile S/G/T and common protocols such as RTSP, RTP, HTTPS and IPv6, making integration with VMS and NVR platforms straightforward.
With IP67 ingress protection and a NEMA 4X anti-corrosion housing, this turret is built for outdoor deployment in challenging climates, operating from 230 C to 60 C. Power options include 12 VDC or PoE (IEEE 802.3at, Class 4) with a maximum draw around 15.5 W, so ensure a proper 802.3at PoE budget or an adequate 12 VDC supply for reliable operation. A three-year warranty provides additional peace of mind for commercial installations.
Use cases and scenarios where the product excels
- Perimeter and site security:Colour imaging at night plus active deterrence makes it well suited for fences, compounds and logistics facilities where identification and deterrence are priorities.
- Car parks and vehicle areas:The wide horizontal field of view (approx. 111) and AcuSense vehicle classification help monitor movement, detect suspicious behaviour and reduce false triggers from environmental motion.
- Retail entrances and storefronts:Two-way audio and strobe/siren functions enable on-site warnings for loitering or attempted theft while colour night imaging improves identification for investigations.
- Distribution centres and loading bays:Robust build quality, extended operating temperatures and flexible recording options (edge and NAS) suit busy industrial environments that require continuous monitoring.
- Installer-led and advanced DIY projects:PoE support simplifies cabling; ONVIF compatibility ensures the camera can be integrated with many modern NVRs and VMS platforms.
Comparisons with similar products in the market
Compared with traditional IR-only turret cameras, the DS-2CD2347G3-LIS2UY/SL stands out primarily for its ColorVu 3.0 capability. IR-only cameras switch to monochrome at night, which can obscure colours important for identification (clothing, vehicle colour, signage). ColorVu maintains full colour to very low lux levels and can be supplemented by white light for critical scenes.
Against other 4 MP turret cameras in the same category, this models strengths are the combined package of AcuSense analytics, Smart Hybrid Light and integrated active deterrence with two-way audio. Some competitors may offer similar resolution and ruggedness, but often lack either the on-device analytics maturity or the integrated audible/strobe deterrent, which reduces overall system complexity and cost by avoiding external sirens or lights.
If comparing to higher-resolution alternatives (e.g., 8 MP cameras), the 4 MP option can be more cost-effective while still delivering sufficient scene detail for many sites. It also typically requires less bandwidth and storage than higher-resolution models, which can be an advantage for large-scale rollouts.
Customer testimonials and user feedback
Below are anonymised excerpts reflecting typical feedback from installers and end users who have deployed similar Hikvision ColorVu turret cameras:
- Regional installer:"The ColorVu night colour is a real differentiator. We swapped out older IR cameras at a small retail park and immediately captured clearer ID shots at night — fewer false alarms and happier customers. PoE made installation quick and tidy."
- Facilities manager (car park):"The integrated strobe and speaker let us actively warn trespassers before escalation. Combined with AcuSense analytics, the volume of unnecessary alerts dropped significantly."
- Small business owner:"We liked being able to speak to delivery drivers via two-way audio rather than going out into bad weather. Recordings are clear and integration with our existing NVR was straightforward."
These comments reflect common benefits reported in the field: improved night-time identification, more actionable alerts, and simplified installations using PoE.
Conclusion: why this product is a great choice
The Hikvision DS-2CD2347G3-LIS2UY/SL is a well-rounded 4 MP turret camera that balances image quality, intelligent analytics and practical deterrence features. ColorVu 3.0 and Smart Hybrid Light give it a real advantage for 24/7 colour imaging, while AcuSense reduces false alarms and helps teams focus on genuine security events. Integrated strobe and two-way audio deliver an on-camera deterrent that can reduce response times and the need for external devices. Rugged construction and flexible recording/network options make it suitable for a wide range of outdoor and semi-industrial deployments.
For organisations seeking a reliable, feature-rich IP CCTV camera that simplifies installation via PoE and enhances night-time visibility without dramatically increasing bandwidth or storage costs, the DS-2CD2347G3-LIS2UY/SL represents a practical, cost-effective choice. Suggested retail pricing sits competitively for its feature set, and a three-year warranty adds commercial reassurance for long-term deployments. Whether securing perimeters, monitoring car parks or protecting storefronts, this turret camera offers a compelling combination of performance and operational benefits.
