CineTreak CT-PT31K 12G NDI

The CineTreak CT-PT31K NDI 4K PTZ Camera is a professional broadcast-grade pan-tilt-zoom camera designed for live production, streaming, conferencing, and education. It features a 1/1.8" Sony CMOS sensor and 31x optical zoom, delivering UHD 4K60 output with simultaneous HDMI, 12G-SDI, USB, and NDI HX3/IP streaming. With AI human tracking, 255 presets, and wide protocol support, it provides a powerful and flexible solution for modern multi-camera workflows.

The CineTreak CT-PT31K NDI 4K PTZ Camera is a high-end professional imaging system built for demanding broadcast, live streaming, and AV production environments. Equipped with a 1/1.8-inch Sony CMOS sensor and 8.42 megapixels of resolution, it produces sharp, detailed, and color-accurate footage with strong performance in low-light conditions.

Its powerful 31x optical zoom lens (plus 8x digital zoom) enables everything from wide venue coverage to tight close-ups without repositioning the camera. The camera supports UHD 4K video at up to 60fps and delivers simultaneous output through HDMI 2.0, 12G-SDI, USB-B, and IP/NDI HX3 streaming interfaces, making it suitable for integrated broadcast systems and hybrid production workflows.

Advanced AI human tracking automatically detects and follows subjects, keeping them centered in the frame for smooth, hands-free operation—ideal for presenters, lecturers, and live performers. With support for up to 255 preset positions, operators can quickly switch between predefined angles for dynamic multi-scene productions.

The CT-PT31K supports professional streaming protocols including RTMP, RTSP, RTMPS, SRT, and ONVIF, along with control standards such as VISCA, VISCA over IP, RS-232/422/485, and Pelco D/P. This ensures compatibility with a wide range of production switchers, controllers, and streaming platforms.

Audio is supported via a 3.5mm stereo input with embedded audio over HDMI, SDI, and IP outputs. Advanced 3D digital noise reduction enhances image clarity, particularly in low-light environments.

Installation is flexible with PoE (Power over Ethernet) support for single-cable setups or a standard 12V DC power adapter. The PTZ mechanism provides smooth 170° pan and 120° tilt movement with variable speed control for precise framing.

Combining high-resolution imaging, intelligent automation, and professional connectivity, the CT-PT31K is a complete PTZ solution for modern video production environments.
