My point still stands though.
Well, actually your original one doesn't as you've now acknowledged below
Regardless of the laptop/device IP (in the 192.168.x.x range set via DHCP from the router) the Polis software is still only going to recognise the static public-facing IP address my ISP has set for my 'Home' router. Not a problem if you are permanently based in one location.
That is essentially what I said at the start.
Trouble is, how will the Polis system cope when I use my laptop from a different location and I do not have access to the 'Home' router?
From their perspective it's how will you cope?
I suspect that the requirement for a static IP address is simply another layer of security - ok, anyone with the knowledge can spoof an IP address, but at least the Polis are doing what they can to make the system as secure as possible.
Have you tried switching off, and on again ?
Alan, I would love to be able to switch
you off and on. In fact, I bet your missus would love to be able to do it more than anyone
