Subject detection runs on the camera's own processor, so there is no tracking PC to rack or license. PTZOptics quotes a maximum tracking distance of 120 ft, about 37 m, for the 30x, the furthest in the line. Presenter-Lock stays with the chosen person while others walk through frame. To move on to another speaker, send a left/right arrow from the camera's web page, the IR remote or a VISCA joystick; for a panel debate, Auto Framing takes over with a group composition.

Behaviour is configured, not left to chance. You decide where tracking starts, where the head parks afterwards, how long it waits before reacting and which preset it returns to if the subject is lost. Two reserved presets, 150 to start tracking and 151 to stop it, let a show controller or one joystick key pass the shot from automation to a human operator and back. During a livestreamed council meeting, the camera follows whichever member takes the floor while the gallery crew concentrates on sound and graphics.

The web interface offers four output modes: IP plus HDMI or SDI, IP plus USB, USB plus HDMI or SDI, and an all-interfaces mode capped at 30 fps. Coax runs of roughly 60 to 100 m on the BNC 3G-SDI connector (SMPTE 424M) carry embedded audio, for the run back to a hardware switcher; HDMI 1.3 covers short hops. Over USB-C 3.0, Teams, Zoom and OBS see a standard UVC camera, and Zoom adds far-end PTZ control.

Over IP the encoder produces two streams in H.264, H.265 or MJPEG. It pushes RTMP or RTMPS directly to YouTube or another streaming CDN, serves RTSP to recorders and sends SRT, protected by a 10 to 79 character passphrase, when a feed must cross the internet to a remote gallery. NDI|HX3 is native, with no licence to buy: it runs on NDI 6.3, can be switched off in the web interface, and its transport is set to RUDP, multicast, TCP or UDP. Desk audio enters through a line-level 3.5 mm socket and rides along in the video as AAC sampled at 44.1 or 48 kHz, or as G.711A; a line output feeds monitoring.

Most control systems already speak its language. VISCA over IP, Sony VISCA, ONVIF for video management platforms, HTTP commands and MIDI run over the network. On the serial side, RS-232 links a chain of heads within 30 m and RS-485 stretches to 1.2 km, both with VISCA, Pelco-D and Pelco-P. The head pans through 340° (±170°) at as much as 100°/s and tilts 90° up and 30° down at a maximum of 69.9°/s; each of its 255 memory positions is recalled to 0.1°. Preset tours with adjustable interval, range and speed give an unattended room view during breaks.

API routes tell a script if the head is in motion, confirm arrival on a recalled preset and return a snapshot from either stream, so automated cuts land on a settled picture. SuperJoy, vMix, OBS, Wirecast, TriCaster, Blackmagic switchers, a Stream Deck plugin and the Hive cloud platform all drive it.

Courtrooms, town halls and campuses ask security questions, and the answers are short. There are IR sensors on both faces of the body, a Kensington slot against theft, and privacy mode, which swings the lens aside and cuts every output during a closed session. Digest authentication guards the API by default, guest login stays off until enabled, firmware uploads need credentials, and the camera is NDAA compliant. For a recorded hearing or exam, an NTP-synced time overlay can sit in a corner of the picture. Two programmable side buttons call a preset, Home, privacy mode or image freeze without opening the web page.

A single Cat5e or Cat6 run to a PoE port (802.3af) delivers power, picture and control; a 12 V supply is in the box for anywhere else. Hung upside down, the head detects that it is inverted and rights the image, and pan/tilt limits, retained after a reboot, keep it off the audience. Each unit can answer to an mDNS name such as council-room.local. Operating range: −10 to +40 °C, indoors.

Free firmware releases arrive for the 12x, 20x and 30x on the same schedule, which is how native NDI, NDI|HX3 and NDI 6.3 reached cameras already installed. Send us room depths, the shot sizes you need and your switcher model: we will show where the 30x earns its place, where a 12x or a 20x is the better buy, and confirm SDI, NDI and PoE compatibility before anything ships.
