Ilensi ye-varifocal CCTV luhlobo lwelensi yekhamera evumela ukulungiswa kobude be-focal obuguquguqukayo. Oku kuthetha ukuba ilensi inokulungiswa ukuze inike i-engile eyahlukileyo yokujonga, ekuvumela ukuba usondeza okanye ukhuphe umxholo.

Iilensi zeVarifocal zihlala zisetyenziswa kwiikhamera zokhuseleko kuba zibonelela ngokuguquguquka ngokwembono. Umzekelo, ukuba ufuna ukujonga indawo enkulu, ungayibeka ilensi kwi-engile ebanzi ukuze ubambe indawo engaphezulu. Okanye, ukuba ufuna ukugxila kwindawo ethile okanye into ethile, ungasondeza ukuze ufumane imbonakalo esondeleyo.

Xa kuthelekiswa neelensi ezizinzileyo, ezinobude obungaguqukiyo, iilensi ze-varifocal zibonelela ngokuguquguquka ngakumbi ngokubhekiselele kwindawo yekhamera kunye nokugubungela indawo. Nangona kunjalo, zihlala zibiza kakhulu kuneelensi ezizinzileyo, kwaye zifuna ukulungiswa okungakumbi kunye nokulinganiswa ukuqinisekisa ukusebenza kakuhle.

Xa kuthelekiswa nei-parfocalIlensi yokusondeza ("yokwenyani"), ehlala igxile njengoko ilensi isondeza (ubude befocal kunye notshintsho lokukhulisa), ilensi ye-varifocal yilensi yekhamera enobude befocal obuguquguqukayo apho ukugxila kutshintsha khona njengoko ubude befocal (kunye nokukhulisa) butshintsha. Iilensi ezininzi ezibizwa ngokuba yi-"zoom", ngakumbi kwimeko yeekhamera ze-fixed-lens, eneneni ziilensi ze-varifocal, ezinika abayili belensi ukuguquguquka ngakumbi kuyilo lwe-optical (ububanzi befocal, i-aperture ephezulu, ubungakanani, ubunzima, iindleko) kune-parfocal zoom.
