The exposure modes support multi-level switching among auto, manual, and shutter-priority modes, and image parameters such as white balance, sharpness, and hue can be finely adjusted and customized. Whether you’re capturing cinematic-quality footage for professional live streaming or recording, or performing precise image verification for industrial quality inspection, this system can deliver 4K image quality tailored precisely to the specific application scenario.

II.Three-channel synchronous output, enabling a seamless 4K multi-terminal signal distribution link.

To meet the integration requirements of multi-device connectivity for 4K systems, the CM8410UHE is independently equipped with three synchronous output ports: HDMI, Gigabit Ethernet, and USB 3.0. A single module supports three types of transmission modes simultaneously, significantly reducing the need for external adapters and simplifying the cabling structure of the entire 4K equipment setup. The HDMI port natively supports direct output at 4K@30fps, enabling plug-and-play connection to professional monitors and large 4K displays for real-time, zero-latency on-site video monitoring. The USB 3.0 port complies with the universal UVC/UAC protocols and is compatible with YUV, H.264, and MJPEG encoding formats, making it ideal for connecting to industrial PCs, desktop computers, and embedded hosts, thus facilitating lightweight deployment of live streaming and desktop recording 4K systems.
