Kuvhura kwelenzi, kunowanzo zivikanwa se "diaphragm" kana "iris", ndiko kuvhura kunopinda nechiedza mukamera. Iyo yakafara yekuvhura iyi, iyo yakakura huwandu hwechiedza inogona kusvika kune kamera sensor, nekudaro ichipesvedzera kuratidzwa kwemufananidzo.
Aperture yakakura (diki f-nhamba) inobvumira chiedza chakawanda kudarika, zvichikonzera kudzika kwemunda. Kune rumwe rutivi, aperture yakamanikana (yakakura f-nhamba) inoderedza kuwanda kwechiedza chinopinda mulenzi, zvichiita kuti pave nekudzika kukuru kwemunda.
Saizi yeaperture value inomiririrwa neF-nhamba. Iyo yakakura iyo F-nhamba, iyo idiki iyo mwenje flux; ukuwo, iyo yakakura kuwanda kwechiedza. Semuenzaniso, Nekugadzirisa aperture yeCCTV kamera kubva F2.0 kusvika F1.0, sensor yakagamuchira chiedza chakapetwa kana kupfuura kare. Uku kuwedzera kwakaringana kwehuwandu hwechiedza kunogona kuve nemhedzisiro inobatsira pamhando yemufananidzo. Mamwe eaya mabhenefiti anosanganisira kuderedzwa kwekufamba blur, mashoma marenzi lenzi, uye zvimwe zvigadziriso zvepazasi kuita kwechiedza.
Kune akawanda makamera ekutarisa, iyo aperture ndeye saizi yakatarwa uye haigone kugadziridzwa kugadzirisa kuwedzera kana kuderera kwechiedza. Chinangwa ndechekudzikisa kuomarara kwese kwemudziyo uye kuderedza mitengo. Nekuda kweizvozvo, aya makamera eCCTV anowanzo kusangana nematambudziko makuru mukupfura munzvimbo ine mwenje wakadzikama pane munzvimbo dzine chiedza chakanaka. Kuripira izvi, makamera anowanzo kuve akavakirwa-mukati infrared mwenje, shandisa infrared mafirita, gadzirisa iyo shutter kumhanya, kana kushandisa akateedzana ekuwedzera software. Aya ekuwedzera maficha ane zvawo zvazvakanakira nezvazvakaipira; zvisinei, kana zvasvika kune yakaderera-light performance, hapana nzira inogona zvachose kutsiva iyo yakakura aperture.
Mumusika, marudzi akasiyana-siyana ekuchengetedza kamera lenses aripo, akadai seakagadziriswa iris board lenses, yakagadziriswa iris CS mount lenses, manual iris varifocal/fixed focal lenses, uye DC iris board/CS mount lenzi, etc. Jinyuan Optics inopa huwandu hwakawanda hweCCTV lenses ine apertures kubva kuF5 iris, iris inovhara uye Auto cover, iris inovhara uye Auto cover. iris.
