Finally the resolution. We do not want to be missing out on an information, because we do not have enough sensor density. So the resolution refers to the special degree, the degree of special equity, the density of information that is captured through the digital sensor.
Those four are the dimensions which will be important for our discussion because we will be talking about cameras that excel in hopefully many or all four dimensions, ideally of these dimensions. And if you can do that, then we have a camera, or a set of cameras that you can place in a remote environment and the cameras will communicate information that will be as complete as possible in this sense.
