Stick up cam wired generation 3

Hi all I have a couple of questions regarding the wired stick up cam generation 3 which I have 3 of 1. All 3 have batteries in them as backup but what’s the point if my power and Wi-Fi go off the cam will be on because of the battery but can it still record motion if no WiFi? 2. I also have the ring alarm and pay for full monitoring this also has battery back up and mobile 3G back up question is will my gen 3 cams use this 3G signal also if Wi-Fi goes down to keep recording motion Hope that all makes sense
