Johnny bought the OwlCam, and now that they are out of business, he doesn't have access to the online backup. Leo says that their online servers were likely shut down. If it still records, there may be an SD card option, or maybe WiFi sync. But Zirgo recently bought all Owlcam assets, so there's always hope that they may continue it on.
Johnny's church bought a MEVO plus for streaming services. Leo says it's a great option. But it's only one camera that pans and zooms. But it's 4K, so he can stream four different 1080p angles. But he can't do multiple cameras together. Leo recommends the Blackmagic ATEM Mini for that. $300 and it gives him four different HDMI connections. But he also needs cameras that won't time out and shut down after 29 minutes.
Check out ElGato, they have a page that talks about doing a streaming video setup with multiple cameras. RODE's USBGo mics are also very good for the money. SURE also makes mics for the iPhone and he can stream directly from that with a much better solution than from a desktop!
