Detailed specifications and their benefits
The DS-2CD2T47G3-LIS2UY/SL’s specification sheet reads like a checklist for professional installers. At its heart is a 1/1.8" progressive scan CMOS sensor that captures 4 MP (2688 × 1520) video at up to 30 fps. This resolution offers a balance of fine detail and efficient storage use when paired with modern codecs such as H.265 and the enhanced H.265+ format.
The imaging system combines a fixed 4 mm, F1.0 lens with ColourVu processing. The F1.0 aperture significantly improves low-light sensitivity, allowing the sensor to gather more light and produce color images where other cameras would only show monochrome. ColourVu extends this capability with optimized ISP algorithms to keep footage naturally colored at dusk, dawn and in near-darkness when supplemented by the camera’s hybrid lighting.
Hybrid lighting is a defining advantage: the camera integrates white light and IR LEDs, automatically adapting to the scene. White light preserves true color for identification and evidential purposes, while IR provides covert illumination when needed. The illumination supplement reaches approximately 60 m, making the camera suitable for larger perimeters and open spaces.
On the analytics front, Hikvision’s deep-learning capabilities enable person and vehicle detection, face capture and perimeter protection zones. These features reduce nuisance alarms caused by animals, falling leaves or shadows and make event searches more efficient—useful for security teams that must triage large volumes of footage.
Audio and active deterrence are built into the housing: dual onboard microphones capture ambient sound, a speaker delivers two‑way audio and pre-recorded messages, and an integrated siren/strobe can be triggered for active response. Combined with classification analytics, this enables automated or operator-initiated deterrence workflows.
From a resilience perspective, the camera is rated IP67 and NEMA 4X for harsh-weather and corrosive environments, operates from -30 °C to 60 °C, and supports power via 12 V DC or PoE (IEEE 802.3at, Class 4). Network security features include TLS 1.1/1.2/1.3, HTTPS and ONVIF compatibility, while local storage via microSD (up to 512 GB) with ANR provides redundancy if the network is interrupted.
Use cases and scenarios where it excels
The DS-2CD2T47G3-LIS2UY/SL is built for situations where night-time color evidence and proactive security matter. Typical applications include:
- Perimeter and site surveillance:Large outdoor sites such as logistics yards, warehouses and storage facilities benefit from the 60 m hybrid illumination and the camera’s ability to clearly identify people and vehicles at night.
- Parking areas and car parks:Colour night images aid in reading vehicle colors and detecting suspicious activity, while analytics help filter vehicle-based alarms from irrelevant motion.
- Building façades and entrances:The wide horizontal field of view (≈95.2°) and two‑way audio make the camera effective for monitoring entry points and communicating with visitors or intruders.
- Retail and commercial exteriors:Active deterrence (siren/strobe, voice warning) combined with analytics reduces loitering and vandalism near storefronts.
- Higher-spec residential projects:Properties that require professional-grade monitoring can use the camera for driveway and boundary surveillance where identification at night is essential.
How it compares with similar products
Within Hikvision’s ColourVu family, the DS-2CD2T47G3-LIS2UY/SL sits at the mid-to-high end thanks to its large sensor, F1.0 aperture and hybrid lighting. Compared with standard ColourVu 2 MP variants, the 4 MP sensor provides more detail for identification and forensic review, while the broader illumination reach and built‑in analytics reduce the need for supplementary lighting and add automation.
Against alternative technologies, such as pure low-light (Starlight) sensors or other vendors’ low-light solutions, the hybrid-light approach offers a useful middle ground: it preserves color in near-darkness (a Starlight camera may still produce color, but often at lower fidelity), and white-light activation provides immediate visual clarity when required. Pure IR-based cameras retain covert operation but sacrifice color information that can be critical for investigations.
Compared with dome or turret cameras, a fixed bullet like this model offers longer reach illumination options and a more visible deterrent presence, especially when the white light or strobe is triggered. However, turret/dome models can be preferred where vandal resistance or discrete appearance is more important.
Finally, while premium optics and larger sensors can be found in higher-cost models from competitors, the DS-2CD2T47G3-LIS2UY/SL strikes a balance of image quality, analytics and active deterrence at a price point that fits many commercial deployments. Suggested retail price (as provided) is 319.0—positioning it competitively for projects that demand color night evidence without moving to the most expensive flagship options.
Customer feedback and installer perspectives
Specific named customer reviews are not provided here, but installers and site managers who choose ColourVu models commonly highlight a few recurring benefits. Typical feedback themes include:
- Night-time color quality:Many users note that ColourVu cameras produce surprisingly clear and identifiable color images in conditions where older cameras produced monochrome footage.
- Reduced false alarms:Installers appreciate the deep-learning classification for person/vehicle detection, which cuts down on time spent chasing irrelevant motion alerts.
- Ease of integration:ONVIF support and standard codecs simplify integration with NVRs and VMS platforms, a major practical advantage on multi-camera projects.
- Active deterrence effectiveness:Reports often mention that visible white light and audible warnings have a measurable deterrent effect in retail and parking environments.
For prospective buyers, these recurring observations can serve as real-world indicators of performance beyond laboratory specifications. If you’re evaluating the camera for a project, request sample footage or demo installations from your reseller to confirm performance in your specific lighting and environmental conditions.
