Introduction to the Hikvision DS-2CD2T47G3-LIS2UY/SL and its key features
The Hikvision DS-2CD2T47G3-LIS2UY/SL is a 4 MP ColorVu hybrid bullet network camera engineered for reliable, 24/7 outdoor surveillance. Combining a large 1/1.8" progressive CMOS sensor, an ultra-fast F1.0 fixed lens (available in 2.8 mm or 4 mm), and hybrid illumination (white-light plus IR), this camera is designed to deliver vivid colour images even in very low light. Beyond image quality, it includes modern AI analytics (person/vehicle classification, perimeter protection and face capture), active deterrence (siren, speaker voice and strobe/white-light warning), two-way audio and flexible storage options—packaged in an IP67 / NEMA 4X rated housing for harsh outdoor environments.
- ColorVu hybrid lightingfor true colour imaging at night with smart supplement light up to 60 m.
- Large-aperture optics(F1.0) that maximise light capture and improve low-light performance.
- Embedded AI analyticsto reduce nuisance alerts and provide actionable events.
- Active deterrencewith built-in speaker, siren and strobe for on-site response without external accessories.
- Flexible power and integration: PoE (IEEE 802.3at) or 12 VDC, ONVIF-compliant for broad VMS compatibility.
- Robust buildrated IP67 and NEMA 4X for outdoor and corrosive environments.
Detailed specifications and benefits
The camera uses a 1/1.8" progressive CMOS sensor to deliver 2688 × 1520 (4 MP) resolution, paired with a bright F1.0 fixed lens available in 2.8 mm (wide) or 4 mm (narrower) options. The larger sensor and wide aperture allow faster shutter speeds and cleaner images in low light, reducing motion blur and improving identification of faces and licence plates at practical distances.
- Resolution:4 MP (2688 × 1520) for clear, detailed images suitable for monitoring and evidence capture.
- Lens:2.8 mm or 4 mm, F1.0 — more light-gathering capability than typical F2.0–F2.8 lenses.
- Field of view:111.1° (2.8 mm) or 95.2° (4 mm) to cover wider areas or focus on mid-range corridors respectively.
ColorVu hybrid illumination combines white-light and IR to provide colour images even when ambient lighting is extremely low. When high-visibility colour is needed, the white supplement light can be triggered; IR remains available for longer-range illumination when white light is not desired.
- Illuminator:Hybrid white light + IR, effective up to 60 m.
- IR wavelength:850 nm.
- Image processing:WDR 130 dB, 3D DNR, defog and EIS to maintain usable images in backlit or challenging weather conditions.
The camera supports H.265 and H.264 codecs, including H.265+/H.264+ optimisations to reduce bandwidth and storage needs without compromising image quality. Multiple streams and region-of-interest (ROI) support make it flexible for recording and remote viewing scenarios.
- Compression:H.265 / H.264 (with + variants).
- Frame rate:Up to 25/30 fps at full 4 MP depending on region.
- Streams:Multiple simultaneous streams for local recording, NVR, and remote clients.
Integrated deep-learning analytics provide person/vehicle classification, perimeter protection (line-crossing and intrusion), and face capture. These capabilities significantly reduce false alarms by filtering irrelevant motion events such as shadows or small animals. The camera also includes active deterrence: a configurable siren, voice alarm and a strobe/white-light warning that can be triggered on events or remotely to scare away intruders.
- Analytics:Person/vehicle classification, perimeter protection, face capture for proactive monitoring.
- Audio:Arrayed dual microphones plus speaker; two-way audio and support for common codecs (G.711, AAC, MP3, etc.).
- Deterrent:Built-in siren, voice alarm and configurable white-light strobe.
Designed for flexible deployment, the camera supports PoE (IEEE 802.3at, Class 4) for single-cable power and data, or 12 VDC where PoE is not available. It integrates with ONVIF-compliant systems and Hikvision’s own platforms (Hik-Connect, Hik-Central). Storage options include on-board microSD up to 512 GB with ANR, and NAS support using SMB/CIFS or NFS.
- Power:PoE (IEEE 802.3at, max ~18 W) or 12 VDC.
- Storage:microSD up to 512 GB, NAS support, and ANR for interrupted network recording.
- Network:RJ45 10/100 Mbps, ONVIF, ISAPI, Hik-Connect/Hik-Central support.
The DS-2CD2T47G3-LIS2UY/SL is built to withstand harsh outdoor conditions with IP67 and NEMA 4X ratings for dust, water and corrosion resistance. Operating temperatures range from -30 °C to 60 °C, making it suitable for extreme climates.
- Ingress protection:IP67; NEMA 4X corrosion resistant.
- Physical:Dimensions ~286.7 × 93.3 × 91.2 mm; weight approx. 1.25 kg.
Use cases and scenarios where this camera excels
The DS-2CD2T47G3-LIS2UY/SL is a versatile option for many outdoor surveillance needs where colour identification at night and active deterrence matter. Typical scenarios include:
- Retail and commercial sites:Colour images at night help identify shoplifters, vehicles and suspect activity in parking lots, loading docks and store fronts. The active deterrent can discourage criminals before incidents escalate.
- Perimeter and car-park monitoring:Person/vehicle classification reduces false alarms from foliage or animals, while ColorVu ensures licence plates and clothing colours are discernible after dark.
- Residential estates and gated communities:The blend of two-way audio and deterrent features allows guards or homeowners to communicate with visitors or warn off trespassers.
- Critical infrastructure and industrial sites:Rugged housing and extended temperature range make the camera suitable for factories, substations, and outdoor equipment yards.
- Transport hubs:Bus depots, small transit terminals and private shuttle parking benefit from clear, low-light colour imaging and AI-driven event filtering.
Comparisons with similar products in the market
When selecting an outdoor bullet camera, buyers typically weigh low-light performance, analytics accuracy, integration flexibility and cost. Here is how the Hikvision ColorVu hybrid bullet stacks up:
- ColorVu hybrid vs IR-only cameras:Traditional IR cameras switch to monochrome at night, losing colour cues. The ColorVu hybrid provides colour images in near-dark conditions using white-light supplementation, improving identification of clothing, vehicle colours and signage. IR-only models may offer longer covert ranges but lack colour detail.
- Colour illumination vs constant white-light models:Some colour night cameras rely on always-on white illumination which can be intrusive or energy intensive. The hybrid design here balances IR and white light, allowing configurable triggers to limit nuisance lighting while providing colour when needed.
- AI-enabled vs non-AI cameras:Built-in person/vehicle classification reduces false alarms and improves efficiency. Non-AI cameras often require more human verification or additional analytics licensing in VMS platforms.
- Compared with other brands:Competing manufacturers offer similar hybrid or colour-night products; the decision often comes down to integration (ONVIF support, VMS compatibility), warranty and service, plus price. The DS-2CD2T47G3-LIS2UY/SL offers a compelling feature set (F1.0 lens, active deterrent, dual audio) that is competitive for the suggested retail price range.
