It would be great to have a version of the S2 which supported external network camera - weatherproof external PoE CCTV cameras are small and cheap, and would be much easier to attach to a fence or outside wall when there’s no clear view of the road from a window. And it means that the Telraam unit itself can be inside somewhere convenient, using WiFi or Ethernet to connect to the camera and provide backhaul if there’s no LTE.
