CineTreak CT-PT31K 3G is a professional 4K PTZ camera for live broadcasting, conferencing, education and remote production. Its 1/1.8-inch 8.42MP Sony CMOS sensor and 31x optical zoom deliver up to UHD 4K60 over HDMI and IP, while 3G-SDI provides reliable HD output up to 1080p60. AI human tracking, 255 presets, tally, PoE, local microSD recording and VISCA, serial and IP control simplify automated multi-camera workflows.
The CT-PT31K 3G combines a 1/1.8-inch Sony CMOS sensor, long optical zoom and a quiet, precise PTZ mechanism for professional studios, venues, education, conferencing and streaming production.

The 1/1.8-inch Sony CMOS sensor with 8.42 effective megapixels delivers sharp, color-accurate video up to 3840 × 2160 at 60 fps. The 6.91–214.64mm lens provides 31x optical and 8x digital zoom, a 60° to 1.98° horizontal field of view, f/1.35–4.6 aperture and fast autofocus. Minimum illumination of 0.5 lux, a signal-to-noise ratio above 50 dB and 3D noise reduction help retain clarity in challenging light.

Advanced AI tracking automatically detects and follows people, keeping a presenter, lecturer or performer correctly framed without continuous operator input.
The PTZ mechanism covers ±170° pan and −90° to +120° tilt. Speed is adjustable from 0.1–120°/s for pan and 0.1–60°/s for tilt, while up to 255 presets recall prepared compositions quickly. Three IR receivers improve command reception, and sleep mode reduces consumption to below 400 mW between productions.
HDMI 2.0, 3G-SDI up to 1080p60, USB-B and RJ45/IP can operate simultaneously. H.264/H.265 plus RTMP/RTMPS, RTSP/RTP, SRT and ONVIF support IP and hybrid production.

High-resolution imaging, intelligent automation and professional connectivity suit studios, live streams, conference rooms, lecture halls, houses of worship and other one- or multi-camera installations. Simultaneous outputs can feed local switching, recording and IP distribution at the same time.
