AIVIS-C40T

AISpeech AIVIS-C40T - 4K PTZ camera for video conferencing, 12x optical zoom, USB 3.0, HDMI, 3G-SDI, IP

The AISpeech AIVIS-C40T is an Ultra HD camera that provides excellent video conferencing quality in 4K resolution. At the heart of the camera is a Sony UHD CMOS 1/2.8" sensor with a resolution of 3840x2160, designed for video conferencing. The 12x optical zoom combined with a 16x digital zoom delivers a very detailed image, while the wide-angle lens of 72.5° and 260° horizontal rotation allow coverage of medium to large rooms. Advanced noise reduction with 2D and 3D filters minimizes grain, ensuring the image remains stable and clear even in low light conditions.

The camera connects to a computer in the room via USB 3.0 in plug-and-play mode, without complicated setup. HDMI and 3G-SDI outputs are also available, along with IP streaming with PoE power. The built-in USB Host port allows connection of AISpeech AI microphones via USB or Bluetooth adapters - video and audio are then transmitted on a single channel, with two-way audio. Combined with the AIVIS-MT100 audio-video tracking module and AISpeech ceiling microphone arrays, the camera creates a complete speaker tracking system that real-time locates active individuals and directs the lens towards them - in conferences, lectures, and events in large rooms.
