Stream external camera to Ionic app

Hi all,

I would like to buy a Bluetooth or Wifi camera and stream it in my ionic app.
So you could make your own video-doorbell, or security camera at home.

I saw a GitHub project from 2016: https://github.com/Moonware/cordova-cameraserver/
But that seems to be doing lots of requests to a local IP to continuously show and update images.
Is there a better solution or is there anyone with a proof of concept voor this?
For example; which camera can I use best? And what would be the best way, bluetooth or WiFi?

I hope someone can help me towards a solution!
Thanks in advance!
