  1. SDK Version: expo sdk 44
  2. Platforms(Android/iOS/web/all): both android and ios
  3. Add the appropriate “Tag” based on what Expo library you have a question on. video intercom system

We are doing cross platform app using Expo cli. May i know which library should i use for video intercom system ? usage: Condo building has intercom and use to communicate between Visitor and Resident. Resident use mobile app (expo) to see the visitor’s live video via outside door camera and able to call / accept the call to/from visitor.

Can we implement without eject the expo app ? As our app has many functions and we do not want to eject the app just to add this video intercom system.

Appreciate your advices.
