Sometimes a camera may lose connection to the main switching device during a live production. This can be a result of Low quality WiFi, an unexpected phone call, low battery, etc.
If any of these events occur, you can quickly recover a camera source or replace it in your production while recording is still taking place.
Completely close the app on the affected device.
Re-launch the app, and choose "Use as camera".
Open the "Inputs" tab on your main switching device.
Tap the device to re-synchronize and add it to your production.
If you have "Record On All Cameras" enabled, a new video clip will begin once the camera is synched.
