I am planning to build a robot that has a video camera attached so I can actually see where the robot is going while I remotely control it. I'm having trouble figuring out what kind of camera to use for a remote application like this. I am needing something with long-range coverage at least greater than 1000 feet, and preferably greater than 2000. I was thinking about using a web cam, since I will be controlling things from my computer, but I'm not sure how to integrate it with a wireless network, especially with this kind of range.
