B27 20 4K PTZ Conference Camera01


4K Ultra-high resolution

Using 1/1.8-inch UHD CMOS sensor with a maximum of 8.42 megapixels, high quality images in 4K (3840x2160) can be achieved. And downward compatible with 1080P, 720P and other resolutions.High-quality & ultra-high resolution 4K lens, 20x optical zoom, horizontal field of view over 60 °.Supports HDMI 2.0 specification, can directly output 4K uncompressed digital video.Supports low-power sleep / wake-up function, and consumes less than 400mW in sleep mode.The ultra-high noise-to-noise ratio of the new CMOS image sensor can effectively reduce the image noise in low illumination conditions, and the 2D and 3D noise reduction algorithms can greatly reduce the image noise, even in the case of ultra-low illumination, keep the picture clean and clear. The image signal to noise ratio is as high as 55dB or more.





Rich and complete interface


Support HDMI2.0 HD output, and also equipped with 3G-SDI interface, the effective transmission distance up to 150 meters (1080p30). HDMI, 3G-SDI, USB3.0, LAN four channels can simultaneously output 4 channels of high-definition digital signals.A variety of control methods, RS232, RS485, network and USB can be used to control the camera.Support image auto flip function for easy installation and useEffectively solve the impact of projector, TV and other high light equipment on shooting people.
