， ，Ubwoko bwumutekano Kamera Yumutekano:
Ibyuma bifata kamera byumutekano biza muburyo butandukanye, buri kimwe cyagenewe guhuza ibikenewe byihariye byo kugenzura.Gusobanukirwa ubwoko bwinzira ziboneka zirashobora kugufasha guhitamo igikwiye kugirango ushireho kamera yumutekano.Hano hari ubwoko busanzwe bwaumutekano wamafoto yumutekano:
1 ，Lens: Lens ihamye ifite uburebure bumwe hamwe n'umwanya wo kureba, bidashobora guhinduka.Nuburyo buhendutse bukwiranye no kugenzura agace runaka udakeneye guhinduka kenshi.Lens zihamye ziraboneka muburebure butandukanye, bikwemerera guhitamo umurima wifuza.
2 ，Lens ya Varifocal: Lens ya varifocal itanga uburebure bushobora guhinduka, bikwemerera guhindura umurima wo kureba intoki.Itanga ihinduka muguhindura urwego rwa zoom kandi nibyiza mubihe aho agace kagenzurwa gashobora guhinduka cyangwa gusaba urwego rutandukanye.Indwara ya Varifocal ikoreshwa muburyo bukenewe aho bisabwa guhinduka, nko kugenzura hanze.
3 ，Kuzamura Lens:Lens zoom itanga ubushobozi bwo guhindura uburebure bwumurima hamwe numwanya wo kureba kure.Iremera byombi optique zoom na zoom zoom.Optical zoom ikomeza ubwiza bwamashusho muguhindura ibice bya lens, mugihe zoom zoomisiyo yagura ishusho muburyo bwa digitale, bikaviramo gutakaza ubuziranenge bwibishusho.Lens zoom zikunze gukoreshwa mubisabwa aho kugenzura kure hamwe nubushobozi bwo gufata amakuru meza ni ngombwa, nko mubice binini byo murugo cyangwa hanze.
4 ，Lens-Inguni: Inguni nini-ngari ifite uburebure bugufi bwo kwibanda, bivamo umurongo mugari wo kureba.Birakwiye kugenzura ahantu hanini cyangwa ahantu hafunguye aho gufata icyerekezo kinini ni ngombwa.Ibice bigari bikoreshwa cyane muburyo bwo kugenzura nka parikingi, ububiko, cyangwa kugenzura hanze.
5 ，Lens: Lens ya terefone ifite uburebure burebure, itanga umurima muto wo kureba no gukuza cyane.Nibyiza kubikurikirana birebire cyangwa ibihe aho gufata amakuru yihariye kure ni ngombwa.Lens ya terefone ikoreshwa mubisabwa nko kumenyekanisha icyapa, kumenyekanisha mu maso, cyangwa kugenzura ingingo zikomeye uhereye kure.
6 ，Lens:Lens ya pinhole ninzobere kabuhariwe ntoya cyane kandi ifite ubwenge.Yashizweho kugirango ihishe mubintu cyangwa hejuru, byemerera gukurikiranwa rwihishwa.Lens ya pinhole ikoreshwa cyane mugihe kamera igomba guhishwa cyangwa gushishoza, nko muri ATM, inzugi z'umuryango, cyangwa ibikorwa byo kugenzura rwihishwa.
二 ，Nigute ushobora guhitamo lens nziza nziza kumutekano wawe Kamera？
Guhitamo lens nziza nziza ya kamera yawe yumutekano nintambwe yingenzi mugukora neza no gufata amashusho meza cyane.Hano hari ibintu bimwe na bimwe ugomba gusuzuma muguhitamo lens:
Ubwoko bwa Kamera:Menya ubwoko bwa kamera yumutekano ufite cyangwa uteganya kugura.Ubwoko butandukanye bwa kamera, nkamasasu, dome, cyangwa PTZ (pan-tilt-zoom), birashobora gusaba ubwoko bwihariye cyangwa ubunini.
Uburebure: Uburebure bwibanze bugena umurima wo kureba nurwego rwa zoom.Ipimwa muri milimetero (mm).Hitamo uburebure bwibanze bujyanye nibyo ukeneye.Hano hari amahitamo amwe:
Lens-Inguni(2.8mm kugeza 8mm): Itanga umurima mugari wo kureba, ubereye gutwikira ahantu hanini cyangwa kugenzura ahantu hanini.
Lens isanzwe (8mm kugeza 12mm): Itanga icyerekezo cyuzuye kibereye porogaramu rusange yo kugenzura.
Lens ya Terefone (12mm no hejuru): Itanga umurima muto wo kureba ariko itanga ubushobozi bwo guhinduranya ubushobozi bwo gukurikirana intera ndende cyangwa hafi-hafi.
Umwanya wo kureba (FOV): Reba agace ushaka kugenzura nurwego rwibisobanuro bisabwa.Umwanya mugari wo kureba ni ingirakamaro ahantu hanini hafunguye, mugihe FOV ifunguye nibyiza kubice byihariye bigenewe gukurikiranira hafi.
Aperture: Aperture igena lens ubushobozi bwo gukusanya urumuri.Ihagarariwe na f-numero (urugero, f / 1.4, f / 2.8).Hasi ya f-nimero yerekana ubwaguke bwagutse, butuma urumuri rwinshi rwinjira mumurongo.Ubugari bwagutse ni ingirakamaro mubihe bito-bito cyangwa gufata amashusho asobanutse mu mwijima.
Ishusho Sensor Guhuza: Menya neza ko lens ijyanye nubunini bwerekana amashusho ya kamera yawe.Ingano rusange yerekana amashusho arimo 1/3 ″, 1 / 2.7 ″, na 1 / 2.5 ″.Gukoresha lens yagenewe ubunini bukwiye bwa sensor bifasha kugumana ubwiza bwibishusho kandi birinda vignetting cyangwa kugoreka amashusho.
Lens Mount: Reba ubwoko bwa lens mount ikenewe kuri kamera yawe.Ubwoko busanzwe bwimisozi burimo CS mount na C.Menya neza ko lens wahisemo ihuye n'ubwoko bwa kamera.
Varifocal na Lens Ihamye:Lens ya Varifocal igufasha guhindura uburebure bwintoki intoki, bitanga guhinduka kugirango uhindure umurima wo kureba nkuko bikenewe.Lens zihamye zifite uburebure bwateganijwe kandi butanga umurongo uhamye wo kureba.Hitamo ubwoko bukwiye ukurikije ibisabwa byo kugenzura.
Bije:Reba bije yawe mugihe uhitamo lens.Indangagaciro nziza-nziza hamwe nibintu byateye imbere birashobora kuba bihenze ariko birashobora gutanga ubuziranenge bwibishusho kandi biramba.
Inganda nisuzuma:Ubushakashatsi bwakozwe nabakora inganda bazobereye mumashanyarazi yumutekano.Soma ibisobanuro byabakiriya kandi ushake ibyifuzo kugirango uhitemo ibicuruzwa byizewe kandi bizwi.
， ，Guhitamo Lens yo mu nzu na Hanze: Ni irihe tandukaniro?
Mugihe uhisemo lens yo kugenzura imbere cyangwa hanze, hari itandukaniro ryibanze ugomba gusuzuma bitewe nibiranga ibidukikije.Dore ibyo ugomba kumenya:
Amatara:Ibidukikije byo hanze bikunze kugira urumuri rutandukanye, harimo urumuri rwizuba, igicucu, hamwe n’umucyo muke nijoro.Ibidukikije byo mu nzu, kurundi ruhande, mubisanzwe bifite urumuri rugenzurwa cyane hamwe no kumurika.Kubwibyo, guhitamo lens bigomba kuzirikana ibibazo byihariye byo kumurika bya buri bidukikije.
Hanze:Hitamo lens ifite aperture yagutse (f-numero mike) kugirango ukusanye urumuri rwinshi mumucyo muto.Ibi bituma ubona neza nubuziranenge bwibishusho mugihe bwije, bwacya, cyangwa nijoro.Byongeye kandi, lens ifite ubushobozi bwiza bwurwego rushobora gukemura itandukaniro riri hagati yizuba ryinshi nizuba ryigicucu neza.
Mu nzu: Kubera ko ibidukikije byo mu nzu bisanzwe bifite itara rihoraho, lens ifite aperture iringaniye irashobora kuba ihagije.Lens ifite f-numero irenze gato irashobora gutanga ubuziranenge bwibishusho muburyo bwo murugo bidakenewe ubushobozi bwagutse.
Umwanya wo kureba:Umwanya ukenewe wo kureba urashobora gutandukana ukurikije ingano n'imiterere y'ahantu hagenzurwa.
Hanze: Ahantu ho hanze bisaba umurima mugari wo kureba ahantu hanini neza.Lens-angle lens isanzwe ikoreshwa kugirango ifate icyerekezo cyagutse, cyane cyane ahantu hafunguye nka parikingi cyangwa inyubako zo hanze.
Mu nzu: Umwanya wo kurebera mu nzu urashobora gutandukana bitewe n'akarere runaka gakurikiranwa.Rimwe na rimwe, lens yagutse irashobora kuba ikwiriye gutwikira icyumba kinini cyangwa koridoro.Ariko, ahantu hagufi cyangwa aho bikenewe gukurikiranwa birambuye, lens ifite umurima muto wo kureba cyangwa ubushobozi bwo guhindura uburebure bwibanze (lens varifocal) irashobora guhitamo.
Kurwanya Ikirere: Kamera yo kugenzura hanze hamwe na lens bigomba kuba byateguwe kugirango bihangane nikirere kibi, nkimvura, shelegi, umukungugu, cyangwa ubushyuhe bukabije.Ni ngombwa guhitamo lens zagenewe gukoreshwa hanze, akenshi ziza zifite ibintu birwanya ikirere nkibiziritse bifunze kugirango birinde ubushuhe n’imyanda.
Kurwanya Vandal:Ahantu ho hanze, hari ibyago byinshi byo kwangiza cyangwa kwangiza.Reba lens ifite ibintu birinda ibintu nka casings cyangwa domes idashobora guhangana ningaruka kugirango wirinde kwangirika no kwemeza imikorere ya kamera nubuziranenge bwibishusho bitabangamiye.
Guhuza IR:Niba sisitemu yawe yo kugenzura ikubiyemo infragre (IR) kumurika ijoro, menya neza ko lens ihuza urumuri rwa IR.Lens zimwe zishobora kugira akayunguruzo ka IR kugirango zongere ubwiza bwibishusho kumanywa mugihe zituma IR imurika neza nijoro.
