Key Features Intelligent lecturer tracking: Built-in leading image recognition and tracking algorithm, without any auxiliary positioning camera or tracking host, it can also track the target stably, accurately and quickly. Strong anti-interference ability: Once the tracking target is locked, it will be free of disturbances of other moving objects or projectors etc. Smooth tracking: The sensitivity of action can be adjusted and it will not be affected by target’s unobvious movement or gestures. Strong environmental adaptability: The tracking performance is not affected by classroom’s size, shape or seats layout. Ultra wide dynamic exposure function:The tracking target would not be darken in front of strong light background with projectors etc. Multiple tracking modes: Support multiple tracking modes, including tracking mode, movie mode and area tracking mode. Ultra HD: 1/2.8-inch high-quality 4K CMOS sensor is used to present vivid ultra high-definition video, vividly showing the target’s facial expressions and actions. Wide view angle and distortion-free lens: Using ultra wide-angle, distortion-free camera; supports 3X digital zoom and EPTZ control at the same time. Low Noise and High SNR: Low Noise CMOS effectively ensure high SNR of camera video. Advanced 2D/3D noise reduction technology is used to further reduce the noise, while ensuring image sharpness. Multiple video compression:265, H.264, MJPEG. Multiple video outputs: Support SDI, USB3.0 and LAN (Gigabit). Multiple streams : Support five streams, simultaneously output close-up main stream, close-up sub-stream, panoramic stream, panoramic sub-stream and blackboard writing stream. POE support: A single network cable can support power, control, and video output simultaneously, thus simplifying wiring installation. Multiple installation: Wall mount and in-ceiling mount for options. Networking control interface: Controlling via Network can meet differe
