For a workshop I'm doing in a couple weeks, I needed to create a simple photo booth type app in the dashboard.
Whilst I could do it with a ui_template node, I thought it would be useful to have a node that wrapped up accessing the webcam from the dashboard. I'm not aware of this existing already.
It isn't published to npm yet, but there's a PR open against our UI nodes repo, and here's a quick demo of it.
PR: Add ui_webcam node by knolleary · Pull Request #45 · node-red/node-red-ui-nodes · GitHub
Features include:
- sends the captured image as a Buffer in png or jpeg format
- optional 5 second countdown when taking a photo
- can be remotely triggered (but the end user must have activated the webcam and given the dashboard permission to turn it on)
- supports multiple webcams (the end user can pick which one to use)
At the moment, its pretty much feature complete (aside from more testing) for what I need, but I'm sure there will be other options that could be added.
I'll update this topic when its available on npm.
