Hoping someone has some experience with this, as I am a newbie with HomeKit.

I am using two tp-link CPE 210’s to get internet from my house to an outbuilding that has my solar panels on it. The solar system is plugged into the Ethernet port on the client 210. They have been working great, and for an added bonus, I have WiFi to operate the garage doors on that building from MyQ. The two CPE’s are configured as access point and client.

I now want to add an outdoor camera on an adjacent building that is in the range of the access point. If I put another client CPE over there, can I use a POE camera and plug it into the Ethernet port on the CPE? If so, will it be considered to be on the same network as the hubs in my house (2 mini’s and a new Apple TV 4K). Or is there a better way to do this?
