DS-2CD2147G3-LI(S2U)Y

The Hikvision DS-2CD2147G3-LI(S2U)Y is a professional 4 MP Smart Hybrid Light ColorVu fixed-dome network camera designed for high-quality surveillance in offices, hotels, hospitals, retail premises, residential developments, schools, warehouses and other commercial facilities. It uses a 1/1.8-inch Progressive Scan CMOS sensor with up to 2688 × 1520 resolution, an F1.0 super-aperture lens, 2.8 mm or 4 mm fixed-lens options and ultra-low-light colour performance down to approximately 0.0001 lux. Hikvision's ColorVu technology and HikAI-ISP provide high-quality 24/7 colour imaging and improved noise reduction, while Smart Hybrid Light automatically combines IR and white illumination with a range of approximately 30 metres. The camera also provides 130 dB WDR, BLC, HLC, 3D DNR, electronic image stabilization and deep-learning-based human and vehicle classification, including line crossing, intrusion, region entrance and region exit analytics. It supports H.265+/H.265/H.264+/H.264 compression, microSD storage up to 512 GB, PoE, NEMA 4X corrosion resistance, IP67 weather protection and IK10 vandal resistance; the -S2U version includes an arrayed dual microphone and audio interfaces. For VEGA Digital IT Solutions LLC, this model can be offered as part of a professionally designed Hikvision CCTV system in Dubai; however, an important SIRA point is that I could not find DS-2CD2147G3-LIS2UY in SIRA's published approved-camera list dated 31 March 2026. Therefore, it should not be described as an individually “SIRA-approved camera” unless VEGA has a newer valid SIRA certificate for that exact model and suffix. SIRA approval is model-specific, and its technical requirements also restrict audio recording without prior permission.The related DS-2CD2047G3-LI(2U)Y is the compact 4 MP ColorVu mini-bullet version, using the same 1/1.8-inch sensor, 2688 × 1520 resolution, F1.0 lens, 2.8/4 mm fixed-lens options, 130 dB WDR, human/vehicle analytics, Smart Hybrid Light and up to 40 m supplementary illumination, together with IP67 and NEMA 4X environmental protection. Importantly for Dubai projects, the exact DS-2CD2047G3-LI2UY is listed by SIRA under approval SIRA/2025/7/11385, while SIRA's March 2026 list also includes DS-2CD2047G3-LI2UY/SLRB under SIRA/2025/7/11528.The DS-2CD2047G3-LI2UY/S(L)(RB) family adds two-way audio, dual microphones and active deterrence; Hikvision identifies the /SL version with white strobe lighting and the /SRB version with red/blue warning lights, so the exact ordered suffix must match the SIRA certificate rather than assuming approval across the complete family. The DS-2CD2347G3-LI(2U)Y provides the same core ColorVu platform in a turret form factor with 4 MP resolution, F1.0 optics, Smart Hybrid Light, 130 dB WDR, AI human/vehicle filtering, IP67 and NEMA 4X protection; the DS-2CD2347G3-LI2UY is specifically SIRA approved under SIRA/2025/7/12268.The enhanced DS-2CD2347G3-LIS2UY/S(L)(RB) adds dual microphones, two-way audio, alarm interfaces and active strobe/audio deterrence; SIRA's published list specifically shows DS-2CD2347G3-LIS2UY/SRB under SIRA/2025/7/11532, while I did not find the /SL suffix separately in that published list. This makes exact SKU verification especially important when VEGA Digital operates as a SIRA-approved CCTV supplier and Hikvision integrator, because the approved certificate must match the actual supplied camera rather than only the general product family.For SIRA-compliant CCTV system installation, VEGA Digital should begin with an approved security survey and camera-layout design identifying entrances and exits, reception and cash-handling areas, restricted zones, parking and vehicle approaches, perimeter areas, blind spots, illumination conditions, camera mounting heights, identification distances, network topology, recording retention, NVR/storage capacity, UPS backup and control-room requirements. SIRA's published technical specifications require security cameras to remain visible rather than hidden, outdoor cameras to have at least IP66 protection, cameras facing strong natural or artificial light to provide at least 110 dB WDR, and cameras installed at 4 metres or higher to provide remote zoom and focus capability; cameras capable of audio recording must not record audio unless SIRA permission is obtained.Consequently, these fixed-lens ColorVu models should be positioned at heights and locations appropriate to the approved design, while a Hikvision motorized-varifocal model should normally be selected where the SIRA design requires installation at or above 4 metres and remote adjustment is necessary. VEGA Digital can then install the approved Hikvision cameras using suitable junction boxes and brackets, CAT6/fibre infrastructure, managed PoE switches, Hikvision NVRs, secure VLANs and UPS protection; configure H.265+, WDR, Smart Hybrid Light, privacy masking, human/vehicle analytics, recording schedules, NTP synchronization and cybersecurity settings; and keep microphones disabled unless authorized. Final commissioning should include day/night image testing, field-of-view and identification checks, recording/playback and retention tests, network and UPS failure tests, analytics verification, preparation of as-built drawings and camera schedules, and confirmation that every camera model and suffix installed matches its applicable SIRA approval certificate. This allows VEGA Digital IT Solutions LLC to deliver not only Hikvision products, but a complete SIRA-oriented CCTV solution for Dubai covering design, supply, installation, configuration, testing, documentation and commissioning.
