Overview
- HDMI over Wifi Encoder Decoder: The video encoder and decoder come with 5G+2.4G dual-band Wifi antenna, providing strong network connection. 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: With H.265 and H.264 codec, the HDMI encoder and decoder provide users with high-quality video transmission in low latency. The encoder supports SRT, HLS, RTMP(S), RTSP, ONVIF and UDP protocols; while the decoder supports SRT, Onvif, RTSP, and UDP protocols.
- Wifi Roaming Encoder: The video encoder supports seamless Wifi roaming. It can remember multiple Wifi credentials. It measures signal strength all the time and automatically jumps to the strongest Wifi signal without interrupting video transmission. The decoder supports adding 30 video sources to the source list so that you can select any of them for decoding at any time.
- DIY Button function: The encoder supports 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 supports encoding 4 streams at the same time with different protocols. It supports text/picture/time OSD, NTP sync. and image preview through web UI. Both the encoder and decoder support online upgrading for more features. Both the devices support web UI and Cloud control.
