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\n- 【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\n- 【NDI \u0026amp; PoE One-Cable ? LCD IP for Instant Setup】NDI 6 \u0026amp; HX3 certified NDI camera (verifiable on NewTek's website). Built-in LCD displays the camera's IP address for instant setup. A single Ethernet cable handles low-latency NDI video transmission, PoE power, and remote PTZ control. HDMI 2.0\/LAN: 4K 60fps, USB 3.0: 4K 30fps, 3G-SDI: 1080p 60fps. Fully compatible with vMix, OBS, Propresenter, Zoom, and Teams on Windows and Mac\n- 【AI Auto-Tracking \u0026amp; Auto-Frame ? 255 Presets, Efficient 4K Control + Dual Stream】Gen-3 AI tracking smoothly follows the speaker in real time, while Auto-Frame intelligently adjusts pan, tilt, and zoom to keep the subject perfectly composed ? no manual adjustments required. High-speed autofocus maintains 4K sharpness during motion and zooming. 255 presets for instant multi-angle switching. H.264\/H.265 dual streaming supports simultaneous 4K recording and platform live streaming with independent bitrate control. Two tasks, one camera\n- 【Silent Operation \u0026amp; Broadcast Compatibility】Ultra-quiet belt-drive PTZ motor runs near-silently in any environment. High-speed 340° pan \/ 120° tilt for complete coverage. Compatible with VISCA, Pelco-D\/P, Blackmagic ATEM, vMix, and Wirecast. Gravity sensor auto-flips the image when ceiling mounted. One install, professional 4K workflow ready\n\u003c\/p\u003e\u003cp\u003eProduct description\u003c\/p\u003e\u003cp\u003eFoMaKo 60FPS 4K NDI PTZ Camera\u003c\/p\u003e\u003cp\u003e4-channels Video Output\u003c\/p\u003e\u003cp\u003eFoMaKo 4K Ultra HD PTZ Camera | NDI-Certified \u0026amp; AI-Powered Auto Tracking\u003c\/p\u003e\u003cp\u003eWhy does my K820N show a black screen when connected to a Blackmagic ATEM switcher via HDMI?\u003c\/p\u003e\u003cp\u003eHow do I keep the image sharp after zooming in manual focus mode?\u003c\/p\u003e\u003cp\u003eHow to find NDI signal?\u003c\/p\u003e\u003cp\u003eHow do I achieve slow, smooth PTZ movements?\u003c\/p\u003e\u003cp\u003eWhat are the different ways to control this PTZ camera?

ATEM lacks scaler. K820N defaults to 4K; so 1080p-only ATEM gets black screen.\u003c\/p\u003e\u003cp\u003eFix: Set HDMI to 1080P, match ATEM frame rate(e.g., both 30fps or 60fps), disable Auto resolution. If not, update firmware \u0026amp; try shorter HDMI 2.0 cable.\u003c\/p\u003e\u003cp\u003eHow do I keep the image sharp after zooming in manual focus mode?\u003c\/p\u003e\u003cp\u003eZooming shifts the optical focal length, so the preset focus position no longer holds. After zooming, simply refocus to restore sharpness（this applies to all PTZ cameras). Digital zoom (16x) engages after optical 20x ends and also requires refocusing\u003c\/p\u003e\u003cp\u003eHow to find NDI signal?\u003c\/p\u003e\u003cp\u003eTo resolve, follow these steps:\u003c\/p\u003e\u003cp\u003e1) confirm your PC and camera are connected to the same router.\u003c\/p\u003e\u003cp\u003e2) log into the camera’s web interface, go to NDI Settings, and turn NDI ON.\u003c\/p\u003e\u003cp\u003e3) reboot the camera, PC, and router. This usually restores the signal.\u003c\/p\u003e\u003cp\u003eHow do I achieve slow, smooth PTZ movements?\u003c\/p\u003e\u003cp\u003eThe pan speed ranges of K820N is 1.8°?80°\/s, supporting smooth slow pans.
