UHD 4K6031x optical zoomNDI HX33G-SDIAI tracking
Detailed images from a wide establishing shot to a distant close-up
The 1/1.8-inch Sony CMOS sensor with 8.42 effective megapixels delivers sharp, color-accurate video up to 3840 × 2160 at 60 fps. The 6.91–214.64mm lens provides 31x optical and 8x digital zoom, a 60° to 1.98° horizontal field of view, f/1.35–4.6 aperture and fast autofocus. Minimum illumination of 0.5 lux, a signal-to-noise ratio above 50 dB and 3D noise reduction help retain clarity in challenging light.
UHD 4K up to 60 fpsHDMI 2.0 and IP/NDI workflows can use smooth 4K video, while 3G-SDI provides professional HD output up to 1080p60.
31x optical zoomThe 6.91–214.64mm range covers a wide venue shot and a tight speaker close-up without moving the camera.
AI human trackingFace and body recognition keep the presenter framed, while face-assisted focus supports fast and accurate focusing.
Production automation
Smooth, quiet and precisely repeatable movement
Advanced AI tracking automatically detects and follows people, keeping a presenter, lecturer or performer correctly framed without continuous operator input.
The PTZ mechanism covers ±170° pan and −90° to +120° tilt. Speed is adjustable from 0.1–120°/s for pan and 0.1–60°/s for tilt, while up to 255 presets recall prepared compositions quickly. Three IR receivers improve command reception, and sleep mode reduces consumption to below 400 mW between productions.
