4K UHD
C51-UVS: Adopts 1/2.5-inch high-quality UHD CMOS sensor with a maximum pixel of 8.51 million. C51-UVB: Adopts 1/2.8-inch high-quality UHD CMOS sensor with a maximum pixel of 8.42 million. Capable of providing excellent 4K (3840x2160) resolution images. Also compatible with various resolutions, including 1080P and 720P. High-quality optical zoom + wide-angle lens, C51-UVS: Adopts an exclusive customized 8 million ultra-high resolution lens with 71° HFoV and 12x optical zoom. C51-UVB: Equipped with 4K ultra-long zoom lens, 20x optical zoom, 16x digital zoom, and 60° field of view. Supports night vision mode, and the infrared filter can be automatically switched.
Remote Control
Provides multiple control methods, using RS232 (RS485 optional) serial port, network, and USB to manage camera settings. , PoE, provides power, control, and audio and video signal transmission for the camera through a PoE Ethernet cable.
Support H.264 encoding
Supports H.264 bitstreams in Slice and SVC encoding modes to meet high-end USB conference video applications. Dual streams, supports two bitstream outputs at the same time (any two modes of YUY2, MJPEG, and H.264), reducing the decoding pressure of the host system.
Low-light performance
The camera uses a 55dB SNR CMOS image sensor and 2D and 3D noise reduction technology to reduce image noise in low-light conditions, thereby ensuring clear images in low-light conditions. Multiple interfaces, support simultaneous output of three 4K ultra-clear video streams through USB3.0, HDMI1, and network interfaces.
