Surveillance cameras contain a series of lenses whose measurements in millimeters are defined. Lens size gives a camera an area that is being focused, which often shows what happens if it can be zoomed into. 2.8mm gives a wide angle view. Use it when observing small spaces, and lenses greater than 12mm can monitor long-distance sites.
