Detailed specifications and benefits
Understanding the DS-2CD2347G2-LUs technical details makes it easier to match the camera to a particular application. At its core is a 1/1.8progressive-scan CMOS sensor that produces 4 MP (2688 at up to 30 fps, offering a useful balance between detail and bandwidth. The cameras ColourVu capability is complemented by a bright F1.0 aperture lens; this combination supports a quoted colour sensitivity to 0.0005 Lux (AGC on) and provides full-colour imagery even in conditions that would render many conventional cameras monochrome.
The integrated dual warm-white spotlights (smart supplement) provide reliable illumination up to about 30 m. Unlike IR-only systems that produce monochrome night images, the ColourVu setup keeps colour information, which is often crucial for identifying clothing, vehicle colours or other forensic details. When supplemental light is required, the camera can illuminate a scene with natural-coloured warm-white light rather than relying on infrared alone.
On the analytics side, the -LU variant adds deep-learning features such as human/vehicle classification, perimeter protection and face capture. These analytics reduce nuisance alarms by distinguishing between people and vehicles and applying tailored detection rules. Perimeter protection enables more accurate trip-zone monitoring, while face-capture functions can assist in gathering forensic stills for investigations. The built-in microphone provides audio context that can be useful alongside video; codecs supported include G.711, G.722.1, MP3 and AAC-LC with sampling from 8 to 48 kHz.
From a network and storage perspective, the camera supports efficient H.265+/H.265/H.264+ encoding and triple streaming so you can tailor streams for live monitoring, recording and remote viewing. ONVIF S/G/T compliance and common protocols (TCP/IP, HTTPS, RTSP, NTP, SNMP, IPv4/IPv6) make the camera interoperable with many VMS and NVR platforms. Local storage via microSD up to 512 GB and network storage (NAS) with ANR ensure redundancy for critical installations.
Physically, the camera is compact (approx. Ø 138.3 mm × 125.2 mm) and light (~750 g) with an aluminium body rated to IP67 for outdoor use; operating temperatures span -30C to 60C, accommodating many challenging environments. Power options include PoE (802.3af) and 12 VDC, with modest power consumption (approx. 7.6 W PoE), simplifying deployment over existing network cabling.
Use cases and scenarios where this camera excels
The DS-2CD2347G2-LUs combination of high-sensitivity optics, integrated warm-white lighting and intelligent analytics makes it particularly effective in applications where full-colour detail at night improves situational awareness or evidence capture. Typical scenarios include:
- Storefront and retail environmentswhere accurate colour can help identify shoplifters, vehicles and items; the built-in analytics help filter false alerts from moving foliage or small animals.
- Parking lots and car parkswhere vehicle colour, plate area context and pedestrian behaviour matter for incident review; the warm-white lights extend useful coverage while preserving colour.
- Perimeter and gate monitoringwhere classification of human vs. vehicle movement and perimeter trip detection are critical to reducing false alarms and focusing operator attention.
- Residential and multi-dwelling complexesfor higher-end properties that value discreet, attractive hardware combined with clear night-time colour imaging.
- Critical asset protectionin low-light outdoor locations where both visual detail and analytics-driven detection are needed for response or evidence collection.
How it compares with similar cameras on the market
Compared with traditional IR-based CCTV cameras, the DS-2CD2347G2-LU provides a clear advantage when colour information is needed at night. IR illumination yields detailed, high-contrast monochrome images, but it cannot reveal colour — an aspect often important for investigations. ColourVu technology keeps scenes in natural colour where supplemental warm-white lighting is available, giving it an edge for forensic utility.
Against competing colour-focused technologies such as Dahuas LightHunter series or other manufacturers low-light / starlight models, the Hikvision unit is competitive on specs: a fast F1.0 aperture lens, 4 MP resolution and integrated lighting yield strong low-light colour performance. Differences among vendors typically show up in analytics maturity, integration options and software ecosystems. Hikvisions deep-learning features and ONVIF support make the camera interoperable with many NVRs and management platforms; however, installers should confirm specific VMS compatibility for advanced features like face capture or analytics metadata.
For applications requiring extremely long-range illumination or ultra-high-resolution details (e.g., 8 MP+ for long-distance plate capture), specialised PTZs or higher-resolution fixed cameras may be more suitable. The DS-2CD2347G2-LU strikes a balance between price, performance and low-light colour capability that fits many commercial and premium residential needs.
Customer feedback and reviews
Public, model-specific reviews vary by region and deployment, but common themes among installers and end users for cameras with these capabilities include praise for clear, usable colour at night, straightforward PoE installation and the value of onboard analytics for reducing false alarms. Installers often note the compact turret form factor simplifies mounting under eaves or on walls and that the aluminium body gives a premium feel while meeting outdoor durability expectations.
Some customers emphasize the benefit of having an onboard microphone for additional context, though they also recommend considering privacy and local laws before enabling audio recording. As always with advanced analytics, optimal results depend on correct installation height, camera angle and configuration of detection rules to minimise false positives and maximise detection accuracy.
Conclusion: why choose the DS-2CD2347G2-LU?
The Hikvision DS-2CD2347G2-LU (4 mm) is a compelling option for users who need reliable, full-colour imaging in low-light outdoor environments without moving parts. It combines a high-sensitivity sensor and F1.0 lens with integrated warm-white lighting and meaningful deep-learning analytics in a weatherproof turret body. For many retail, parking and perimeter applications, the cameras ability to preserve colour detail at night improves situational awareness and forensics compared with IR-only alternatives.
At a suggested retail price around $179 (street pricing may vary), the DS-2CD2347G2-LU offers a competitive balance of capability and value. Professional installers and system designers will appreciate the PoE support, ONVIF compatibility and flexible storage options, while end users benefit from clearer night-time colour footage and intelligent detection that reduces nuisance alerts.
Before purchase and installation, check the official Hikvision datasheet and local regulations for certifications, warranty and privacy rules relevant to audio capture. With appropriate siting and configuration, the DS-2CD2347G2-LU is a practical, high-impact choice for projects where seeing colour after dark can make a real difference.
