1、Target Tracking: Support AI tracking function, support face centering and target tracking function (menu selectable). Support for WDR, easy to deal with different lighting environments, no matter how harsh the environment is, it can restore the most real you. 2、4K HD: It supports 4K ultra high definition, and can provide 4KP30 image output at most, and is backward compatible with 1080p, 720p and other resolutions. Distortion free lens, wide angle field of view up to 112 degree, small lens, big vision. 3、Low Noise: Using 1/2.5 inch coms with super high signal to noise ratio, with 8.5 million effective pixels, it can effectively reduce image noise under low illumination conditions. At the same time, 2D and 3D noise reduction algorithms are applied, which greatly reduces image noise. In the case of low illumination, the picture is still kept clean and clear, and the signal to noise ratio is more than 55dB. 4、4 Meter Pickup Radius: Built in 4 arrays of high sensitivity microphones, 4 meter pickup radius, omnidirectional pickup, unique noise suppression algorithm, so that your voice can be perfectly presented. Built in high power speaker, AGC automatic gain. 5、Applications: Applicable to various scenarios, can be used for live broadcast, online teaching, video conference, video call, distance education, telemedicine court, etc. A variety of installation methods, support desktop, ceiling, wall, tripod installation.
