Oahu is the lens that determines the amount of light entering the digital camera. Besides the quality of materials as well as manufacturing, usually reflected inside the price, some of the lens characteristics have much effect on the viewed picture.

The subjects are well known in the field of still photography, so that the principles should not be completely unfamiliar for whoever has some practice of family picture taking even in a very basic level.
For most surveillance cameras, lenses are interchangeable. Therefore you ought to decide if the picture seen for the monitor is satisfactory to your application, with reference to the depth of focus, the angle of view and the amount of detail you would like to distinguish.

The overall result is a matter of compromise whereby, by sacrificing somewhat one of the things one gains a much better response from another one.
Fixed focal length is a very common selection: although limiting somewhat the dimension with the space where all objects result clearly perceived (depth of focus), it simplifies the mechanical construction and cuts down on the price.

A lens whose focal length may be manually adjusted is known as a Varifocal lens but shouldn't normally be considered for surveillance purposes.
Equally too sophisticated to the application would be a motorized contact lens, capable of being commanded coming from a distance to select preferred level of detail between wide-angle and telephoto.
