I need a solution that is easy to move around where a Webcam looks at a target I can see on a smartphone at least 200m away preferred up to 1000m away.
The easiest is probably to use 3G to upload image to website on Internet as I then have "unlimited" range. But directly WiFi is cheaper (no need for 3g) and is probably more stable and higher image update rate.
But is WiFi possible at that range?
Or are there other ways to do this?
