The tracking engine lives inside the camera; no external PC is involved. In PTZOptics' figures the 30x has the furthest tracking distance in the series, a recommended maximum of roughly 37 m, and wants the subject picked up no further than about 7.6 m from where tracking starts. Presenter-Lock holds the chosen person as others cross the stage. Arrow commands from the browser, the IR handset or a VISCA joystick pass tracking to the next speaker, and Auto Framing composes a whole panel instead. A January 2026 release made the head calmer about minor subject movement at the long end, exactly where this lens spends most of its working day.

If the speaker walks off, a stop location, a lost-target timer and a recovery preset bring the head back to a safe wide. Calling position 150 switches tracking on and 151 switches it off, so a Stream Deck key or a room control system can hand the camera between operator and automation. At a full-day congress, one technician can leave the long angle to the camera and concentrate on the vision mixer.

Four output modes in the web interface decide which paths are live: HDMI/SDI with IP, USB with IP, USB with HDMI/SDI, or everything together at 30 fps. 3G-SDI on BNC (SMPTE 424M) handles the long coax run from a rear-of-hall position back to a router or switcher, with HDMI 1.3 as the alternative; a hex dial on the back panel fixes resolution and frame rate at power-up. Over USB-C 3.0 the camera registers as a UVC webcam carrying audio (MJPEG 1080p60, YUY2 1080p30), and Zoom meetings can steer it through far-end camera control.

Two independently encoded IP streams leave the RJ45 port in H.264 or H.265, MJPEG also on the second, capped at 102.4 and 20.48 Mb/s, CBR or VBR, each pushing to its own RTMP or RTMPS destination. Encrypted SRT, as caller or as listener, carries a contribution feed from an exhibition hall or stadium to a remote gallery. RTSP and RTP multicast feed recorders and monitoring software.

NDI|HX3 is native, runs on NDI 6.3 and travels as multicast, TCP, UDP or RUDP, whichever the network allows. Support for an NDI Discovery Server and receive groups keeps a venue network with dozens of sources tidy. A line-level mini-jack input carries the mixing-desk feed into the outputs as AAC at a 44.1/48 kHz sample rate, or as G.711A, and a matching jack returns sound for monitoring.

Over the network, the head understands VISCA over IP (5678/TCP, 1259/UDP), Sony's variant on 52381/UDP, ONVIF, the HTTP API and MIDI controllers. Serial installs use RS-232, daisy-chained over 30 m, or RS-485, whose 1,200 m reach can link a gallery to the far balcony; both handle VISCA as well as Pelco-D/P.

Stored positions, 255 of them, are recalled with 0.1° repeatability and a recall speed set in 24 steps; pan reaches ±170° with a 100°/s top speed, while tilt spans −30°/+90° with a 69.9°/s ceiling. Image Presets set whether a recall restores the picture settings saved with it or moves the head only. Since the API confirms arrival on a preset, a show-control script cuts only once the shot has settled. SuperJoy, PT-JOY-G4, the Stream Deck plugin, vMix, OBS and Hive all drive it.

One structured-cabling link (Cat5e/Cat6, 100 m maximum) to an 802.3af PoE port supplies power, video and control; the 12 V adapter in the box covers rooms without PoE. On an inverted mount a gravity sensor puts the picture upright, and pan/tilt limits stop the lens swinging onto spectators. Privacy mode points the lens away and blanks every feed; IR receivers sit front and rear, and a Kensington slot deters theft. IT and public-sector buyers get digest authentication on the API by default, login-protected firmware updates and NDAA compliance. Operation is indoor, from −10 to 40 °C.

Videomaker found the cooling fan audible in a silent room on the 12x; a 30x usually hangs far from any lectern microphone, so it rarely registers. In grey, the body blends into dark ceilings, truss and black-box studios. Send us the throw distance and the shot size you need on the tightest preset, and our team will work out the framing, confirm your switch has the PoE headroom and recommend the output mode before the cameras ship.
