FAQ How to activate an NDI licence
Tips:

• After purchasing, please back up the NDI authorization code, one code per machine to avoid loss.
• You can also use NDI DEMO without purchasing an NDI license. It can be used for 30 minutes after startup, and the screen will be black after 30 minutes, and it can be used again for 30 minutes after restarting. But this only affects NDI, not other protocols (such as SRT, RTMP, RTSP, HTTP, UDP, etc.).
