UVC-G4-Doorbell dead.

I have a G4 wifi doorbell that died a slow death. It was powered with a doorbell transformer originally. It worked great for about 6mo then started rebooting and shutting off. Eventually it would not power on with the doorbell power. I found the USB and powered it that way for a bit, but now is is completely dead.

Is there a good 3rd party doorbell that I can use with protect? I went back to my old Ring doorbell, but I don't want to keep paying for that. I have 5 other Unifi cameras and want to keep it in the same viewer.
