For broadcast-style IP production, the latest Link 4K firmware brings NDI 6.3 with certified HX3 profiles (High at 1080p50/60, Ultra at 4K50/60) and lets compatible switchers and control software adjust iris and shutter remotely. Outside NDI, the encoder delivers H.265, H.264 or MJPEG on a pair of simultaneous streams. SRT with AES encryption handles contribution to a remote gallery over the public internet; RTMP and RTMPS publish straight to YouTube or a CDN; RTSP feeds recorders and video-management systems; multicast lets a single source reach dozens of decoders across a site. ONVIF Profile S certification and NDAA compliance make sign-off by IT departments and public buyers far quicker.

Baseband choices follow cable length. HDMI 2.0 carries 4K60 to a nearby monitor or capture card, whereas 3G-SDI sends 1080p60 (Level A or B) down coax to a rack-mounted vision mixer. The two are alternatives rather than parallel feeds, toggled in the web interface or by remote shortcut, and a rotary dial on the back fixes the output format without a laptop. Over USB 2.0 the camera enumerates as a UVC webcam, up to UHD at 30 fps, which suits a hybrid meeting PC or a streaming laptop in a compact studio.

As an auto-tracking PTZ camera, it computes detection on its own processor, with no tracking PC in the chain. Presenter Lock stays with a selected speaker even while other people walk through the shot. Multi-Target Select assigns an ID to everyone in view, so moving the lock between panellists becomes a single choice in the interface. Auto Framing sizes the shot to the group, and with Tilt-Lock engaged the height stays fixed, so a host walking a stage of constant level never produces nodding shots. The tracking limit given by PTZOptics for this 20x model is about 80 m: a keynote speaker can be followed from the rear balcony of a congress hall. Even a basic serial controller can arm or disarm tracking, as presets 150 and 151 are reserved for that.

The head turns through ±170° horizontally and from −30° to +90° vertically, at speeds from an almost invisible 0.7°/s to a 100°/s pan and 69.9°/s tilt maximum; 255 presets return within 0.1°. Control runs over VISCA over IP (Sony's variant included), an HTTP API with WebSockets, or serial runs of 30 m on RS-232 and 1,200 m on RS-485 using VISCA or Pelco-D/P. Operators can equally drive it from the IR remote, a PTZOptics joystick, vMix, OBS, Wirecast or TriCaster. FreeD position data, currently a beta feature, can drive virtual-set graphics. HTTP commands also put the head into privacy mode or standby once a boardroom session is over, and the on-board tally light warns presenters the moment this camera goes live.

The white housing all but vanishes against pale ceilings, lecture-hall soffits and bright corporate stages. Power, control and video share one PoE+ (802.3at) connection, backed up by a 12 V DC socket. Ceiling installation needs no manual image flip, since orientation is sensed automatically. It works indoors between −10 and +40 °C; for an outdoor graduation or a sports fixture, the camera can go into a third-party weatherproof housing. Power supply, IR remote, USB and RS-232 cables come in the box.

Ahead of an order, our product specialists can check which focal length your camera positions really need, help you decide between an NDI and a Dante AV-H architecture, and quote cameras, white mounts and joysticks together for a multi-room rollout.
