RGBlink RGB25X-UNAI-BK 25X 4K AI PTZ with NDI

The RGBlink RGB25X-UNAI-BK is a professional 4K Ultra HD AI tracking PTZ camera featuring a 25× optical zoom lens, NDI HX3 support, and multi-interface outputs including HDMI, SDI, USB, and IP. Designed for broadcast, education, and live streaming environments, it delivers smooth AI-based subject tracking, high SNR imaging, and flexible control with PoE support.

The RGBlink BK series PTZ camera with 25× optical zoom shoots 4K at 60 frames per second and follows the presenter on its own using AI. It outputs simultaneously over HDMI, SDI, USB and the network – including NDI|HX3, and it can be powered by a 12 V adapter or over PoE+. It suits classrooms, meeting rooms, halls and live productions.

Lens with 25× optical zoom

Focal length 7.1–175.95 mm, aperture F1.61–F5.15 and horizontal field of view 59.2°–2.5° – from the whole room down to a close-up of a face. The 1/1.8″ Sony CMOS sensor with 8.51 MP and 3D noise reduction delivers a picture with a signal-to-noise ratio above 50 dB, and the camera focuses automatically, manually or at one press.

Follows the presenter using AI

The built-in processor recognises a person and keeps them in shot – continuously, or only within a zone you define in the web interface. The camera pans from −110° to +110° at up to 100°/s and tilts ±30° at up to 70°/s, stores 255 presets, and 10 of them can be recalled directly from the supplied remote control.
