B27 12 4k 12x PTZ Broadcast Camera


12x optical zoom High-quality & ultra-high resolution 4K lens,12x optical zoom, horizontal field of view over 71°. HDMI1.4 Support HDMI 1.4 specification, can directly output 4K uncompressed digital video. Low power consumption sleep function Supports low-power consumption sleep / wake-up function, and consumes less than 400mW in sleep mode.



Local Storage Support local storage function, U disk local recording can be realized without NVR.Low illumination Ultra-high Signal to Noise Ratio of 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.
