While it isn't well documented, the depth of focus on a Swann camera is small (i.e. a clear picture is largely only around what the lens is focused upon) and you need to adjust the focus of the Swann cameras to be where you want to look (e.g. if you are looking over a yard, only the location of the yard focused upon will be sharp with the rest more and more out of focus with increased distance from the point of focus.) In other words, the Swann cameras are largely designed for watching a smallish area such as an entry way (or in my applications, the status of equipment movement less than a foot away from the camera.)
