Introduction
The HED-4KW is a wireless, compact, and energy-efficient HDMI encoder consuming only 3.4W and is powered via USB. It enables seamless streaming in 4K@30Hz and one channel of 4K zero-delay loop out, achieving crystal-clear video with bit rates up to 64Mbps using HEVC/AVC compression. Users can easily start/stop streaming with a single click, conveniently adjust the OSD settings, and preview the video stream in real time using the embedded web UI. With built-in dual WiFi 6 antennas, the wireless streaming encoder has more stable network connections. At the same time, the Wifi encoder allows storage of up to 32 SSIDs and it measures the signal strength of each SSID. It will jump between these SSIDs regarding the configuration. The wireless encoder supports simultaneously streaming on up to 4 platforms (YouTube, Facebook, Twitch, etc.) in 1080p@60Hz with different protocols SRT, HLS, RTMP, and RTMPS.
