Hikvision DS-2CD2T47G3-LIY(2.8mm) Product Overview
The Hikvision DS-2CD2T47G3-LIY(2.8mm) is a 4MP ColorVu Smart Hybrid Light fixed bullet network camera designed for detailed perimeter, entrance and general surveillance monitoring. Its 1/1.8-inch progressive-scan CMOS sensor records at up to 2688 × 1520, while the fixed 2.8mm F1.0 lens provides a wide 111.1° horizontal field of view.
Infrared and white-light illumination are rated up to 60 metres, while 130dB WDR helps retain detail in scenes containing bright and shaded areas. Person and vehicle classification is available for supported motion and perimeter events, together with face capture and scene-change detection. This exact LIY model has no microphone, speaker, external audio input/output or alarm input/output, so it must not be advertised as an audio, two-way-audio or active-deterrence camera.
Key Benefits
-
Detailed 4MP imaging: records at up to 2688 × 1520 for clear live viewing and playback.
-
Wide 2.8mm coverage: the 111.1° horizontal view suits entrances, yards, car parks, retail exteriors and broad monitoring areas.
-
ColorVu low-light performance: the large sensor and F1.0 aperture support colour-focused detail where ambient lighting is limited.
-
60m Smart Hybrid Light: provides configurable infrared and white-light operation for supported night-monitoring modes.
-
Person and vehicle classification: supported events can focus on relevant target types and reduce unrelated alerts.
-
130dB WDR: helps preserve detail in backlit and high-contrast scenes.
-
Local recording: compatible microSD-family cards up to 512GB are supported.
-
Protected metal housing: IP67 and NEMA 4X provide weather resistance and moderate anti-corrosion protection.

Night Imaging and Detection
Smart Hybrid Light can use infrared, white light or an intelligently controlled combination according to configuration. ColorVu supports colour-focused low-light monitoring, but practical performance depends on scene illumination, mounting height, reflective surfaces, weather and camera settings. The manufacturer-rated supplement-light distance is up to 60 metres under test conditions.
Person and vehicle classification is available for supported motion, line-crossing, intrusion, region-entry and region-exit events. Face capture and scene-change detection are also supported. Detection results depend on target size, distance, camera angle, lighting, obstruction and correct setup; analytics should not be treated as a guarantee that every event will be detected.
Storage and Compatibility
The internal card slot supports compatible microSD-family cards up to 512GB. A memory card is normally sold separately. Confirm that the selected card is suitable for continuous surveillance recording and that the recording schedule, overwrite behaviour and retention period are configured correctly.
Confirm NVR support for 2688 × 1520 video, required frame rate, person-and-vehicle analytics, Smart Hybrid Light controls, standard PoE capacity, storage-card support and mounting accessories before ordering. ONVIF compatibility can assist third-party integration but does not guarantee access to every Hikvision-specific feature.
Installation Considerations
The 2.8mm lens provides a wide fixed view and cannot zoom remotely. Confirm the required scene width and target distance before installation. Mount the camera on a structurally suitable surface, protect all connections from moisture and follow the manufacturer installation guidance. The final image and detection performance depend on positioning, lighting and configuration.
