YED100-4K is a 5G 4K high-definition image transmission device. It adopts an embedded system architecture. The device supports video acquisition, encoding compression, two-way voice, 5G/4G network transmission, Beidou positioning, data storage and other functions. It supports 4G/5G full Netcom network, supports external interfaces such as Ethernet interface, external audio and video access, TTL serial port, etc., and can be connected to image acquisition devices such as HDMI camera, USB high-definition camera, thermal imaging camera, etc., thermal imager or access RTSP network camera through the network to obtain input video stream. At the same time, it can realize image acquisition and system control of drones, unmanned vehicles, robots, DV cameras and other systems through HDMI, network port, serial port, etc. It supports RTSP, HLS, GB28181 two-way audio and video, WEBRTC, RTMP and other protocols to enter push and pull operations. Using the Fiber Effect Technology scheduling platform, it can realize unified video scheduling and remote control of unmanned systems. At the same time, the built-in second-layer tunnel function can realize SD-LAN function across regions, and quickly convert the copied public network applications into LAN applications.
