DS-2CD2T47G3-LIY

The Hikvision DS-2CD2T47G3-LIY is a professional 4 MP Smart Hybrid Light with ColorVu fixed-bullet network camera designed for perimeter surveillance, commercial buildings, warehouses, parking areas, schools, villas, industrial facilities, logistics sites and other security applications across Dubai and the UAE. It uses a 1/1.8-inch Progressive Scan CMOS sensor with up to 2688 × 1520 resolution, an F1.0 super-aperture lens, and selectable 2.8 mm or 4 mm fixed lenses. Hikvision specifies extremely low-light colour performance down to 0.0001 lux, while ColorVu and HikAI-ISP provide high-quality colour imaging and improved noise reduction in difficult night scenes. Smart Hybrid Light combines IR and white light with three illumination modes and a range of up to 60 metres. The camera also provides 130 dB WDR, BLC, HLC, 3D DNR, defog, EIS, H.265+/H.265 compression, up to 512 GB microSD storage, face capture, and deep-learning perimeter protection including line crossing, intrusion, region entrance and region exit with human/vehicle classification. Its all-metal construction provides IP67 weather protection and NEMA 4X anti-corrosion protection, making it well suited to the UAE's outdoor environment. For VEGA Digital IT Solutions LLC, as a SIRA-approved CCTV solution supplier and Hikvision system integrator serving Dubai and the UAE, this model can be incorporated into professionally designed surveillance systems. However, SIRA approval must be treated as exact-model specific: I checked SIRA's publicly available Approved Camera List dated 31 March 2026, and the exact DS-2CD2T47G3-LIY is not shown in that published list. Therefore, VEGA should verify whether Hikvision has obtained a newer SIRA certificate for this precise model before describing the camera itself as “SIRA Approved” in a BOQ, technical submittal or customer proposal. SIRA requires security devices to be independently examined and approved for use in approved Dubai security systems. The related Hikvision DS-2CD2T47G3-LIS2UY/S(L)(RB) expands the same 4 MP ColorVu platform with additional audio, alarm and active-deterrence capabilities. It retains the 1/1.8-inch sensor, 2688 × 1520 resolution, F1.0 lens, 2.8 mm/4 mm options, 60 m Smart Hybrid Light, 130 dB WDR, deep-learning human/vehicle filtering, face capture, 512 GB microSD support, IP67 protection and NEMA 4X anti-corrosion construction. It additionally includes an arrayed dual microphone, built-in speaker, two-way audio, audio input/output and two alarm inputs/two alarm outputs, allowing alarms and external devices to be integrated with the camera. The /SL version uses a white flashing light, while the /SRB version provides red-and-blue flashing warning lights; audible warnings and flashing lights can be linked to intelligent events to deter unauthorized entry. This model is particularly useful for compound boundaries, warehouse yards, loading areas and restricted entrances where proactive deterrence is required. For SIRA-regulated Dubai projects, however, special attention is required: SIRA states that outdoor cameras must be at least IP66, cameras facing strong light sources must provide at least 110 dB WDR, cameras installed at 4 metres or above must have remote zoom and focus, and cameras equipped with audio-recording capability cannot be used for audio recording unless SIRA permission is obtained. Both models exceed the environmental and WDR thresholds with IP67 and 130 dB WDR, but they use fixed focal lenses, so they should not normally be selected for mounting positions at or above 4 metres where the SIRA remote-zoom/focus requirement applies. Likewise, the microphone on the DS-2CD2T47G3-LIS2UY/S(L)(RB) should remain disabled for recording unless specifically authorized. I also found no exact DS-2CD2T47G3-LIS2UY variant in SIRA's public 31 March 2026 approved-camera list, so current certificate verification is necessary before claiming individual camera approval. For a SIRA-oriented system installation, VEGA Digital should begin with a detailed CCTV survey covering mandatory surveillance areas, entrances and exits, vehicle approaches, perimeter boundaries, cash or sensitive locations, blind spots, lighting conditions, mounting heights, identification distances, pixel-density requirements, network topology, NVR/storage capacity, recording retention and UPS backup. SIRA even provides CCTV design tools for calculating field of view and pixel density, with published pixel-density references including 300 PPM for identification, 125 PPM for recognition and 25 PPM for detection, so camera positioning should be based on the required security objective rather than simply maximizing viewing angle. VEGA can then install the DS-2CD2T47G3-LIY or appropriately approved related model using suitable Hikvision junction boxes, pole/corner brackets, CAT6 or fibre infrastructure, managed PoE switching, Hikvision NVRs, UPS protection and secure CCTV VLANs; engineers configure resolution, H.265+, WDR, day/night behaviour, Smart Hybrid Light, AcuSense human/vehicle analytics, privacy masking, NTP time synchronization, event recording and cybersecurity. For the /SL or /SRB models, alarm and strobe functions can be commissioned where permitted, while microphone recording should remain disabled unless SIRA approval explicitly allows it. Final testing should cover daytime/nighttime image quality, identification performance, recording and playback, storage retention, network/UPS failure, analytics, alarm linkage and all approved fields of view. For Dubai projects, VEGA should also ensure that the Security Plan is certified, every installed camera SKU matches its applicable SIRA approval, and the completed installation passes the security audit before final system certification—making the project a genuinely SIRA-compliant Hikvision CCTV installation, rather than relying only on the camera's technical specifications.
