Full-featured Multi interface: Full function HDMI + SDI + IP + USB four-channel simultaneous outputs, compatibility USB 3.0, support compressed video output, support UVC protocol. 4K Ultra HD: New generation 1 / 2.5-inch high-resolution UHD CMOS sensor with a maximum of 8.51 million pixels, which enables 4K(3840×2160) ultra-high-resolution high-quality images, downward compatibility including 1080P, 720P and other resolutions. 12X Optical zoom + 16X Digital Zoom: Use 71° wide-angle high quality lens, support 12x optical zoom, and 16x digital zoom. Low illumination: new CMOS image sensor with ultra-high SNR can effectively reduce the image noise under low illumination. At the same time, the 2D and 3D noise reduction algorithms are applied to greatly reduce the noise. Even under ultra-low illumination, the picture is still clean and clear. Remote Control: RS232, network and USB can be used to control the camera.
