The current manufacturer specification lists the main Dante AV-H stream at up to 3840 × 2160 and a lighter secondary stream at up to 720 × 480, handy for previews on a control-room multiviewer.

For IP delivery the encoder works in H.265, H.264 or MJPEG and runs two streams at once. SRT, configurable as caller or listener, carries a contribution feed over the public internet to a remote production gallery. RTMP and RTMPS push straight to YouTube, Facebook or a CDN, RTSP serves recorders and video management systems, and multicast lets one encode reach many decoders across a campus. ONVIF Profile S support and NDAA compliance help when the camera has to pass a public-sector or university tender.

Auto-tracking is computed inside the camera, so no tracking PC or extra licence sits in the signal chain. With Presenter Lock, the operator picks a person on screen with the remote's arrow keys and the head stays on that presenter while colleagues or audience members move through the picture; one button press hands the lock to the next speaker. Tracking range for the 20x version reaches roughly 80 m – enough for a lecturer pacing a large auditorium or an executive crossing a town-hall stage while a single technician runs graphics and the stream.

Mechanically, the head pans ±170° and tilts from −30° to +90°. Speeds start at 0.7°/s, slow enough for an on-air creep, and climb to 100°/s on pan and 69.9°/s on tilt for quick repositioning between shots. 255 presets recall with 0.1° accuracy. Network control uses VISCA over IP, while the serial ports speak VISCA, Pelco-D or Pelco-P over RS-232 (up to 30 m) and RS-485 (up to 1,200 m). The IR remote (four addresses, about 9 m), hardware joysticks and production software such as vMix, OBS, Wirecast and TriCaster complete the list. A tally lamp tells talent which camera is on air.

Commissioning is done in a browser. The web interface places short tutorials next to its settings and installs firmware with one click, while a 16-position resolution selector on the rear panel sets the HDMI and SDI format directly at the camera. When no DHCP server answers, the head reverts to a known default address – useful when racks are prepared on an isolated show network the night before load-in.

A single PoE+ (802.3at) cable carries power, control and IP video, with a 12 V DC input as the alternative. Hung upside down from a ceiling bracket, the camera flips its picture automatically. It is rated for indoor use from −10 °C to +40 °C, and the grey housing keeps a low profile against dark studio walls and black stage trusses. Our team can help you compare the Link 4K 20x focal range with the 12x and 30x versions for your throw distance, check the PoE+ budget of your switch and plan Dante subscriptions for a multi-camera room.
