✓【4K 60fps UHD — 1/1.8" CMOS 8.42MP + 20X Optical + 16X Digital Zoom】A genuine 1/1.8-inch UHD CMOS sensor with 8.42 million pixels captures broadcast-grade 4K 60fps video. 20x optical zoom brings distant subjects close; 16x digital zoom pushes further while preserving usable detail — the large sensor gives every zoom step more pixels to work with. Precise broadcast-grade white balance control ensures accurate, consistent color matching across multi-camera productions. Ideal for large venues, broadcast productions, and professional education environments
✓【Low-Light Dominance — 0.5 Lux Sensitivity, 3D Noise Reduction + High SNR】With a proven low-light sensitivity of 0.5 Lux (@ F1.8, AGC ON), the K820N delivers clean, sharp images in challenging lighting — dim sanctuaries, lecture halls, and conference rooms. A high signal-to-noise ratio (≥55dB) and advanced 3D noise reduction work together to eliminate grain while preserving sharp, moving details. A powerful ISP and large 1/1.8-inch sensor suppress noise without sacrificing fine detail, so every frame looks clean and professional
✓【NDI & PoE One-Cable — LCD IP for Instant Setup】NDI 6 & HX3 certified NDI camera (verifiable on NewTek's website). Built-in LCD displays the camera's IP address for instant setup.
