Hello @oxrecs 

Thank you for your detailed post, but I have some questions with your request: 

May I know do you use a tp-link power line Kit in the church before:

For ' Previously I have used a network of 2 powerlines, where the IP camera has been plugged into the non-wifi powerline, and the wifi powerline has been used to broadcast the stream to an IOS or Android phone. The SSID of the network is unique and the IP address of the camera is static. ' 

Does camera get internet at that time, does Andriod phone stream camera over internet? Do you have a Wi-Fi router in your network to assign IP address? 

Hello @oxrecs 

Sorry for the late reply.  If the mobile phone  could access camera through local network (depended on the Camera app on your iPhone) you could try to set up a topology like this: 

• Wired PLC <Ethernet>Camera ( static IP in 192.168.0.X ）
• Wireless PLC <Wireless > Mobile phone (connect to PLC's Wi-Fi,  in 192.168.0.X subnet) 

 If Powerline KIT was in paired status, after being relocated to a different location, most of the time kit could automatically pair to each other automatically (make sure device are paired under the same powerline/ same power meter) .If you need some recommendation, either tp-link powerline KIT could do that, like model TL-WPA4220KIT. 

@oxrecs That sounds great, thank you for update the solution here~
