Q about internet connection requirements

I'm a new user of video doorbell pro.What happens to the functionality when the ISP is down but my home WiFi is still funtional?Will the alerts to my iPhone at home (on the WiFi LAN) still work?Will streaming live view, microphone/speaker on the doorbell from iPhone at home (on the LAN) still work?My expectation: the recording feature would be disabled as the recordings are stored on the Ring servers. Access to the live stream from devices away from home would not work either. However, streaming and alerts to the devices on my WiFi LAN should still work. That data link is still functional when the ISP has an outage.Am I correct? If not, please me.Aloke
