Interactive Streamers with alwaysAI

During the Open Office Hour, Lila highlighted how to build interactive streamers with alwaysAI using Plotly Dash. Plotly Dash is a javascript graphing library which can be used to create dashboard visualizations, in this case, alwaysAI leverages dash for Python. There are two main components to Dash:

Guest Questions

QUESTION: Can we access an alwaysAI streamer from different locations? 

ANSWER (Lila): IP streaming requires that your camera has a fixed IP. As long as IP is public and the port has been enabled, that should work. Here's the docs for the camera streamer

QUESTION: I notice that REACT is not imported, at what point is it brought in?

ANSWER (Lila): The app is all in Python. You can write these components and they are then converted to Python in the backend. I am not sure how the conversion happens in REACT. That's the benefit of using Dash, you can use it and not worry about the backend mechanics of how it works. 

QUESTION: Can we make a custom web interface with alwaysAI using Dash? 

ANSWER (Steve): Yes, this Hacky Hour is to highlight how you can make interactive custom streamer.  Watch the full Hacky Hour to learn how.
