About the DS-2CD2387G3-LI2UY
The Hikvision DS-2CD2387G3-LI2UY is an 8 MP Smart Hybrid Light fixed turret network camera from the Pro Series with ColorVu 3.0, combining 4K UHD resolution with advanced dual-illumination technology and deep learning intelligence. Built on a large 1/1.8" Progressive Scan CMOS sensor with an F1.0 super-aperture M16 lens, this camera is engineered to deliver full-colour imagery in extremely low light conditions without relying solely on supplemental lighting.
At the core of this camera's imaging capability is ColorVu 3.0 technology, which integrates Hikvision's HikAI-ISP image signal processor for advanced noise reduction and dynamic motion trail suppression. The HikAI-ISP delivers noticeably cleaner footage in difficult conditions, including fast-moving subjects and poorly lit environments. 3D LUT technology further refines colour accuracy and consistency across the image, while scene-adaptive Wide Dynamic Range at 130 dB allows the camera to handle extreme contrast between bright and dark areas simultaneously, adjusting automatically based on ambient light levels.
The Smart Hybrid Light system integrates both 850nm infrared LEDs and white light LEDs in a single unit, providing three distinct supplemental lighting modes. In IR mode, the camera operates with standard infrared night vision for discreet monitoring. In white light mode, full-colour footage is produced regardless of ambient lighting. In smart mode, the camera switches automatically from IR to white light upon detecting a human or vehicle target, triggering a vivid colour response to intrusion events. Both IR and white light ranges extend up to 30 metres, with smart supplement light control managing output intensity based on subject distance.
The camera features AcuSense 3.0 deep learning technology, which classifies motion detection events by target type, distinguishing humans and vehicles from irrelevant triggers such as animals, weather, and reflected light. AcuSense 3.0 also includes AcuSearch functionality, enabling image-based video retrieval with a single click, allowing operators to quickly locate specific recorded events without manually scrubbing through footage. This significantly improves post-event investigation efficiency.
Perimeter protection capabilities include line crossing detection, intrusion detection, region entrance, and region exiting, all with human and vehicle target filtering to ensure alarm accuracy. Face capture is also supported as a deep learning function, adding an additional layer of detection capability for high-security zones. Basic event detection covers motion detection with target type filtering, video tampering alarm, and exception handling.
The 2.8mm fixed focal lens provides a wide horizontal field of view of 108.8 degrees, making the DS-2CD2387G3-LI2UY well suited to monitoring large open areas, access points, car parks, and outdoor perimeters from a fixed mounting position. At this focal length the effective depth of field begins at 3.3m to infinity. Video is delivered at up to 25fps at full 4K resolution (3840 x 2160) on the 50Hz setting, with triple streaming support across H.265+, H.265, H.264+, H.264, and MJPEG codecs depending on stream.
The -2U suffix denotes the inclusion of a built-in arrayed dual-microphone system, providing stereo directional audio capture with environmental noise filtering for improved audio quality in outdoor or noisy environments. This eliminates the need for an external microphone in many installations and provides a practical audio record alongside the video stream. Audio compression options include G.711, G.722.1, G.726, MP2L2, PCM, MP3, and AAC-LC.
The -Y suffix denotes anti-corrosion construction rated to NEMA 4X standard, offering enhanced material durability and resistance to corrosion in demanding environments such as coastal locations, industrial settings, and areas subject to chemical exposure. The camera body is all-metal construction and carries IP67 protection against dust and water ingress.
On-board storage is provided via a built-in microSD/SDHC/SDXC card slot supporting cards up to 512 GB, with Auto Network Replenishment (ANR) for footage recovery during network interruptions. NAS storage via NFS and SMB/CIFS is also supported. The camera is compatible with iVMS-4200, Hik-Connect, and Hik-Central, and supports ONVIF Profile S, G, and T for third-party integration. Power is via PoE IEEE 802.3af Class 3 or 12 VDC, with an operating range of -30 degrees C to 60 degrees C.
