Spotlight Cam Wired - 100ft from house - Will it need just Wi-Fi and power? Batter Backup Option?

Hello: I just jumped into the Ring think and am $800 into it at this point. Planning install and trying to identify issues before I open all the boxed. I have the security system, Doorbell Cam gen 3, Outdoor wired floodlight cam and Spotlight Cam wired. Extra sensord ordered and 2 extenders for security system. Questions: 1) I see the specification on the Spotlight cam (wired) has voice communicaiton on 902-928mhz. Will this need to reach back to the security system main receiver on 900mhz or will just Wi-Fi allow cam and 2-way audio. Its 120 feet from house but I am putting up a directional Access Point so it will have a good signal, light of sight. I just wonder if it needs to connect to any of the other Ring receivers? 2) Spotlight cam Wired - Does not seem to have abattery backup. Is this availabe so it functions during short power outages? Thank you
