.
The subjects are well known in the field of still photography, so the principles should not be completely unfamiliar for whoever has some practice of family picture taking even at the very basic level.
In many surveillance cameras, lenses are interchangeable. Therefore you ought to decide if the picture seen around the monitor is satisfactory for the application, with reference to the depth of focus, the angle of view and also the amount of detail you would like to distinguish.
In case you are unsatisfied with the performance with the standard lens supplied, you need to ask to see the way a different lens would help the images you want to observe.
Normally you ought to select the best overall picture for the exact purpose. Note that by changing among the characteristics (i.e. aperture) one modifies other related properties (i.e. the depth of focus).
The entire result is a matter of compromise whereby, by sacrificing somewhat one feature one gains an improved response from a different 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.
You may be knowledgeable about autofocus feature found in modern digital cameras. There isn’t any comparable capability in cameras simply because they must work unattended. A lens whose focal length could be manually adjusted is termed a Varifocal lens but should not normally be considered for surveillance purposes.
Equally too sophisticated for the application would be a motorized contact, capable of being commanded from your distance to select the most well-liked level of detail between wide-angle and telephoto.
Fixed iris or aperture is yet another characteristic to be considered that simplifies construction and operation, albeit by incorporating compromise on picture. It would probably be better to provide sufficient illumination then opting for more complex optics.
In conclusion, regardless of the nice and costly alternatives available, for any simple home surveillance system it might be advisable to select among the simplest lenses, provided that the quality of the picture is sufficient for the intended purpose
