Most IoT development/testing services give you only a portion of the tools you need to actually produce results. For instance, you might have an app that connects to an IoT device so a client can interact with and send commands to a device. Another service might provide the connectivity method. With full-stack Nabto Edge app demos, however, you have free access to both secure P2P connectivity and demo apps with the code fully available for tweaking and experimentation.
In the case of the Nabto Edge Tunnel Video app demo, you can easily set up an RTSP video feed tunneled through Nabto Edge for P2P video streaming on your PC and smartphone. You can have the device set up and ready for testing in minutes, all with no time limits and free of charge.
