Adopts an embedded, medical-grade, cabinet-free design with dustproof and waterproof features to ensure safety and avoid occupying operating room space. The integrated hardware design replaces traditional high-definition video matrix, video interaction server, picture splitter, audio processor, high-definition encoder/decoder, and high-definition recording/broadcasting server, eliminating hardware stacking issues. The core hardware of the digital operating room achieves high functional integration. The all-in-one intelligent hardware, based on a unified circuit design running under the LINUX system, is safe and reliable.
