I think there is value in supporting PoE in reporting status to the cloud because it makes my RG-6 run between the LNA and the DC less than 3 feet. The long run between the DC and my girlfriend’s house is easily accommodated in the 328ft Ethernet distance limitation.
RG-6 is relatively very lossy. It’s an interesting trade-off between Ken’s solution of having a dish and 500ft of RG-6 versus my case of having only a cone, 3ft of RG6 and a run of Ethernet.
There are lots of people with WiFi video surveillance in her neighborhood. Although video only consumes one channel, the traffic load on the channel is nearly 100%. When half the neighborhood is doing this, WiFi becomes somewhat unreliable.
I agree with @kenbarbi that the report from the DC to the cloud, should include the LAN connection type. This can help in narrowing-down problems.
