Overview
- HDMI over Wifi Encoder Decoder: The video encoder comes with 5G+2.4G Wifi6 antenna, providing strong network connection. The IP decoder is with built in 5G+2.4G Wifi. Both are mini, lightweight, and USB-powered, easy for set up.
- 4K Video Transmission: The encoder's max. HDMI input is 2160p@30Hz, max. encoding output is 2160p@30Hz, 64M, and max. loopout output is 2160p@30Hz. The video decoder's max. input is 2160p@60Hz, and max. decoding HDMI output is 2160p@60Hz.
- High-Efficiency IP Streaming: Both are with H.265 and H.264 codec. The encoder supports SRT, HLS, RTMP(S), RTSP, UDP; while the decoder supports SRT, Onvif, RTSP, UDP protocol.
- Wifi Roaming Encoder: The video encoder supports seamless Wifi roaming. It can remember multiple Wifi credentials. It measures the signal strength and automatically jump to the strongest Wifi signal without interrupting video transmission. The decoder supports adding 30 video sources to the list. You can switch the sources for decoding at any time.
- DIY Button function: The encoder support one click to start/stop streaming. Moreover, you can empower new features to the device button. For example, you can set the button to start/stop SRT streaming, or you can set the button to enable/disable OSD display and more.
- Multi-Channel Streaming: The encoder support encoding 4 streams at the same time with different protocols. Support text/picture/time OSD. Support NTP sync. and view preview. Both the encoder decoder support online upgrading for more features.
