SKU : DS-2CD2T83G2-4LI2U 2.8MM
The Hikvision DS-2CD2T83G2-4LI2U represents a surgical fusion of uncompromised optical clarity and ultra-premium security architecture. Engineered for dedicated security administrators and property managers operating within zero-compromise environments, this 8MP powerhouse effortlessly captures breathtaking 4K (3840 × 2160) video footage. By utilizing Hikvision's proprietary AcuSense technology—driven by advanced deep learning algorithms—the camera maintains absolute technical dominance over legacy motion detection systems. This meticulous construction acts as a reliable structural pillar that intelligently classifies human and vehicle targets, completely eliminating annoying false alarms triggered by falling leaves, heavy rain, or stray animals.
Surgical Hybrid Lighting and Audio Telemetry
At the interactive core of its hardware layout is a highly responsive illumination and audio matrix perfectly tailored for intense, long-range 24/7 monitoring. The system deploys Smart Hybrid Light technology, providing a profound functional advantage in establishing perimeter visibility up to a massive 80 meters. The camera utilizes covert infrared (IR) light for standard night vision but instantly activates a powerful white LED light when a target is detected, capturing full-color details of intruders while actively deterring them. To maintain absolute technical dominance over environmental awareness, the unit features an integrated dual microphone array, giving operators the exact physical framework required to record synchronized, high-fidelity audio alongside crystal-clear 4K video.
Industrial-Grade IP67 Chassis and WDR Integration
Meticulously optimized to slash deployment limitations and ensure long-term operational survivability under harsh Middle Eastern climates, the internal optics are encased within a heavy-duty IP67-rated waterproof and IK10 vandal-resistant metal bullet chassis. Defying extreme weather and physical impacts, the camera is further fortified with 120dB True Wide Dynamic Range (WDR) technology. This premium optical refinement delivers the ultimate technical capability required to establish total command over heavily backlit scenes—such as glaring sunlit entryways, loading docks, or horizon lines—ensuring every frame maintains pristine exposure and critical identifying details are never lost in the shadows. Powered seamlessly by PoE (Power over Ethernet) or standard 12V DC.
