How to calculate the distance that covers certain security camera ip?

The distances covered by the cameras are determined by the different lenses they bring, these are measured in millimeters. For example the cameras with lenses of 3.6 and 3.7 millimeters have ranges of 8 to 12 meters, although some reach up to 15 meters. The thicker the lens the more range it has, but also the smaller the viewing angle, ie a 5.0 millimeter lens will have a range of 25-30 meters and an angle of 66 degrees, while a 6.0 millimeter lens may have a Range of 40 to 45 meters and a viewing angle of 56 degrees, although the angles also vary according to the image sensors, for example a sensor ½ with a lens of 6 mm, can cover an angle of 75 degrees and the same 6mm lens with 1/3 sensor, can cover an angle of 56 degrees.
