Tapo cameras can be added to the H500 if they're on the same network (firmware support is also required for both devices). To my understanding, both powerline adapters and range extenders typically broadcast WiFi within the same subnet as your main network by default. Unless specific configurations have been applied, devices connected to any of these networks should be able to communicate with each other as long as they remain on the same subnet. You can double-check the details about the powerline network with their support team.
