Detailed product specifications and benefits
- Image sensor:1/1.8" progressive‑scan CMOS delivering up to 2688 × 1520 (4 MP) resolution. The larger sensor helps capture more light and finer detail compared with smaller sensors at the same resolution.
- Lens & aperture:Fixed F1.0 lens, available in 2.8 mm (approx. 111.1° horizontal FOV) or 4 mm (approx. 95.2°). The super‑fast F1.0 aperture enables excellent low‑light performance and shallower depth of field for clearer subjects at night.
- WDR:130 dB wide dynamic range to handle challenging scenes with strong backlight or mixed lighting.
- Smart Hybrid Light:A combination of white‑light and IR (850 nm) illumination gives full‑colour imaging in low light (ColorVu) and reliable black‑and‑white IR when needed. Minimum illumination is as low as 0.0001 Lux (F1.0 with AGC) and 0 Lux with supplement light.
- Illumination range:Up to 60 m depending on environment, which supports long corridor or perimeter coverage.
- Active deterrence:Built‑in strobe/light and a 2 W speaker enable visual and audible warnings. This reduces dependence on external sirens or strobes and lets you issue live warnings via two‑way audio.
- AI analytics:On‑device deep‑learning features include person and vehicle classification, perimeter protection (tripwire and intrusion detection), and face capture. These improve accuracy and significantly reduce false alarms compared with motion‑only sensors.
- Compression & streams:Supports H.265 and H.264 variants with main/sub/third stream options for efficient bandwidth and storage management.
- Audio:Built‑in dual microphones for improved capture and noise suppression, plus a mono audio output and 2 W speaker for live communication and pre‑recorded warnings. Audio codecs include G.711, G.722.1, AAC‑LC, and MP3.
- Power:12 V DC ±25% (max ~17 W) or PoE IEEE 802.3at (Class 4, max ~18 W), giving installers flexibility on site wiring.
- Local storage:microSD up to 512 GB with ANR (Automatic Network Replenishment) supported to reduce recording gaps during network outages.
- Network & standards:ONVIF S/T/G, ISAPI, RTP/RTSP, HTTPS; supports IPv4/IPv6 and up to 32 concurrent users (device limit) for monitoring and integration with VMS/NVR platforms.
- Ingress & durability:IP67 and NEMA 4X anti‑corrosion rating make this camera suitable for harsh outdoor environments, coastal sites and industrial locations. Operating temperature from -30 °C to 60 °C and humidity ≤95% non‑condensing.
- Form factor:Approx. 286.7 × 93.3 × 91.2 mm, weight ~1.25 kg. Compact bullet body that is straightforward to mount on walls or ceilings with installer‑friendly cabling access.
- Consistently clear, full‑colour images in very low light thanks to ColorVu and an F1.0 aperture, improving situational awareness and evidential image value.
- Built‑in deterrence (strobe + speaker) and two‑way audio let operators intervene or warn intruders immediately, often preventing incidents rather than just recording them.
- AI‑driven analytics reduce false positives from animals, shadows or leaves, so security teams can focus on real events.
- Flexible power and robust ingress protection simplify installation choices and ensure long‑term performance outdoors.
Use cases and scenarios where the camera excels
The DS-2CD2T47G3-LIS2UY/SL is versatile and tailored for situations where nighttime identification, active deterrence and reliable operation are priorities.
For schools, universities, industrial complexes and warehouses, the long illumination range and ColorVu capability mean security teams can identify people and vehicle details at night—license plates, clothing colours and facial detail—while AI analytics help filter routine movement, reducing nuisance alerts.
Car parks and retail exteriors benefit from the camera’s integrated strobe and audio warnings to deter theft, loitering or anti‑social behaviour. Colour imaging at night aids investigations and delivers more useful CCTV evidence to law enforcement and insurers.
For remote substations, telecom sites or transportation hubs, the rugged IP67/NEMA 4X rating ensures cameras tolerate harsh environments. PoE support simplifies deployments where a network switch with PoE is available, and local microSD recording provides redundancy.
Because the camera consolidates illumination, speaker and analytics, installers can reduce the number of separate accessories, saving on time and material costs during new builds or retrofits.
Comparisons with similar products on the market
When choosing a surveillance camera, buyers commonly compare hybrid ColorVu‑style cameras with traditional IR‑only models, other ColorVu models, and competing brands. Here’s how the DS‑2CD2T47G3‑LIS2UY/SL stacks up.
- Colour at night:IR‑only cameras typically produce monochrome images under IR illumination; ColorVu hybrid cameras preserve colour information using white light, which often yields more actionable evidence (vehicle colour, clothing, signage).
- Deterrence:Hybrid models with built‑in strobe and speaker provide immediate deterrence capability; IR‑only units cannot warn or illuminate subjects in colour.
- Energy & light pollution:IR‑only solutions may be preferable where visible lighting is not acceptable; the hybrid approach is better where active deterrence and colour evidence are priorities.
- Sensor and aperture:The 1/1.8" sensor and F1.0 aperture position this model towards the higher end of low‑light performance among ColorVu cameras—many competing ColorVu variants use smaller sensors or slower apertures.
- Integrated features:The combination of dual microphones, a speaker, onboard analytics and NEMA 4X protection makes this bullet particularly well‑suited to industrial and coastal applications compared with entry‑level ColorVu domes that may lack one or more of these features.
Competitors offer similar hybrid or colour‑at‑night solutions, but buyers should compare sensor size, aperture, analytics capability (on‑device vs server), illumination range, ingress rating and integrated deterrence. The DS‑2CD2T47G3‑LIS2UY/SL is competitive on sensor size and aperture, includes robust on‑device AI, and pairs those imaging strengths with practical deterrence hardware.
Customer feedback and installer notes
While individual customer reviews vary by deployment and expectations, common themes from installers and end‑users for cameras in this class include:
- Positive:Consistently praised for excellent low‑light colour detail, straightforward PoE installation, and reduction in nuisance alarms due to person/vehicle classification. Installers often highlight savings from fewer external accessories because of the integrated strobe and speaker.
- Constructive:Some users note configuration of analytics and deterrence settings requires careful tuning—professional installation and initial fine‑tuning are recommended to match sensitivity and warning schedules to the site.
- Integration:Where VMS and NVR compatibility matters, ONVIF support and standard protocols make integration straightforward, but verifying device firmware compatibility with the chosen VMS is good practice.
Example anonymised comments summarising typical feedback:
- "Excellent night colour and deterrence — we saw fewer incidents after enabling the strobe and audio warnings."
- "Robust housing for a coastal site; microSD redundancy is a very useful failover."
- "Analytics cut down false alarms, but initial configuration took a bit of time to tune."
