I-Television ye-Circuit Valevision evaliwe (i-CCTV), eyaziwa nangokuthi ukubhekwa kwevidiyo, kusetshenziselwa ukudlulisa amasiginali wevidiyo kubaqaphi abakude. Awukho umehluko okhethekile phakathi kokusebenza kwamalensi wekhamera e-static kanye ne-CCTV yekhamera ye-CCTV. Amalensi wekhamera ye-CCTV ahleliwe noma aguquguqukayo, kuya ngezincazelo ezidingekayo, njengobude obugxile, i-aperture, i-angle engela, ukufakwa noma ezinye izici ezinjalo. Uma kuqhathaniswa nelensi yekhamera yendabuko engalawula ukuvezwa ngejubane le-shutter kanye nokuvula i-IRIS, i-CCTV Lens inesikhathi sokuvezwa okuhleliwe, kanye nenani lokukhanya okudlula kudivayisi yokucabanga liyalungiswa kuphela ngokuvulwa kwe-IRIS kuphela. Izici ezimbili ezibalulekile okufanele zicatshangelwe lapho ukhetha ama-lens kungubude obugxile kokugxila kanye nohlobo lokulawula i-IRIS. Amasu ahlukahlukene wokukhumula asetshenziselwa ukukhweza ilensi ukuze alondoloze ukunemba kwekhwalithi yevidiyo.
Amakhamera amaningi we-CCTV asetshenziselwa izinhloso zokuphepha kanye nezinhloso zokubhekwa, ezinomthelela omuhle ekukhuleni kwemakethe ye-CCTV Lens. Eminyakeni embalwa edlule, kube nokuhlinzwa kwakamuva kwesidingo samakhamera we-CCTV njengoba ama-ejensi alawulayo afake imithetho ephoqelekile yokufakwa kwamakhamera we-CCTV ezitolo ezithengiswayo, amayunithi okukhiqiza kanye neminye imisebenzi eqondile . Ngokukhuphuka kokukhathazeka kwezokuphepha mayelana nokufakwa kwamakhamera wethelevishini avaliwe-jikelezo ezintweni zasendlini, ukufakwa kwamakhamera wethelevishini avaliwe-njikelezo kuye kwanda kakhulu. Kodwa-ke, ukukhula kwemakethe kwe-CCTV Lens kungaphansi kwemikhawulo ehlukahlukene, kufaka phakathi umkhawulo wenkambu yokubuka. Akunakwenzeka ukuchaza ubude obugxile nokuvezwa njengamakhamera endabuko. Ukuhanjiswa kwamakhamera we-CCTV kusetshenziswe kabanzi e-United States, eBrithani, eChina, eJapan, eSouth Asia nezinye izifunda ezinkulu, okulethe izici zokukhula kwamathuba kwimakethe ye-CCTV lens.
