Resolution= Refers to how much detail can be captured on a camera or displayed on a monitor. Cameras typically capture about 380 horizontal lines of resolution. High resolution analog cameras may capture 450 lines of resolution or more. High resolution IP cameras can record and stream in HD/Megapixel quality. The higher the resolution, the more detail that can be captured in a picture. The monitors and recording devices can generally handle at least as much resolution as the cameras can capture. Also remember that higher resolution images capture larger size frames (file size), and therefor, require more bandwidth to transport and more storage space to archive.
