product details

Product features:


4K ultra high definition

Supports 4K ultra high definition, * available 4K@30fps /25fps image output, with downward compatibility for resolutions such as 1080p and 720p.

Intelligent teaching tracking

Built in leading image recognition and tracking algorithms, smooth and natural tracking effects can be achieved without the need for any auxiliary positioning cameras or tracking hosts. Different cameras are installed before production to achieve teacher or student tracking.

AF lens

Fully customized autofocus distortion free lens, with a wide-angle field of view of up to 46 °/84 °/120 °, small lens, and wide field of view. At the same time, it supports EPTZ for braking without moving, allowing for larger and clearer visibility. The 120 ° field of view lens does not support AF.

● Low illumination

The brand new CMOS image sensor with star level ultra-high signal-to-noise ratio can effectively reduce image noise in low illumination conditions. At the same time, 2D and 3D noise reduction algorithms are applied to significantly reduce image noise. Even in ultra-low illumination conditions, the image remains clean and clear, with a signal-to-noise ratio of over 55dB.

● Supports PoE

The wired network supports PoE power supply, and control, power supply, video, and audio can be completed with just one network cable.
