At present the wireless cameras and hub need to be in close proximity if you want a stable connection as the cameras link directly to the hub and not to the Hub via the wireless network. 

If the hub is connected to a local network via an ethernet cable (or even Wifi) then surely the cameras can connect to the Hub via the wifi network rather than need to be in close proximity to the hub.  This would allow for the hub to be stored in a secure central location and give the cameras better placement options such as front gates, perimeter fences etc all connecting to the hub/s via wifi using outdoor antennas or range extenders.

It would be beneficial have my TP-Link Deco Mesh wifi network and be able to connect my TP-Link Tapo cameras to the hub via this network.
