xfinity cameras ethernet wiring

I have a bunch of XCAM1 cameras and was wondering if there is a way for me to connect them into the network via ethernet instead of streaming wirelessly?  I still have the original pigtail connectors with the jacks labeled 'power' and 'gateway'.  Is it possible that I could backhaul these right back to an XB8 (or, preferably, an unmanaged switch connected to the XB8)?  Or would I possibly need to backhaul them to a switch with POE capability?  (If the latter, managed or unmanaged?)

Note:  one of the primary reasons I am interested in the backhaul approach is because of the recent news articles related to thieves using wi-fi jammers to block wi-fi surveillance cameras.  Example:  https://ktla.com/news/local-news/police-warn-of-thieves-using-wifi-jamming-tech-to-disarm-cameras-alarms/
