Closer to the action, remotely

The UHD CMOS sensor has 8.42 million effective pixels for detailed images across large spaces. Its 6.25–125 mm F1.58–F3.95 lens moves from a wide shot to a close-up with 20x optical zoom, complemented by 16x digital zoom. AI tracking keeps a speaker or performer in frame while the head pans ±170° and tilts from −30° to +90°. Up to 255 presets make shots repeatable.

Feeds for the switcher and network

HDMI outputs up to UHD 4K60 and 3G-SDI up to Full HD 60p. Ethernet with NDI|HX3 and RTSP, RTMP/RTMPS, SRT and ONVIF fits multi-camera IP production, with H.264, H.265 and MJPEG compression. USB-A 2.0 supports UVC and local recording to USB storage. Control options include VISCA over IP, RS-232, RS-485 and UVC; 3.5 mm line input/output handles audio. Power is via 12 V DC or PoE+ 802.3at.
