Yeyiphi ilensi esetyenziswa kwikhamera yeCCTV? Wenza ntoni iilensi zekhamera ye-CCTV? Ungayikhetha njani lens yekhamera ye-CCTV?

一,WumnqwaziLI-Arts isetyenziswa kwi-CCTVCAmera?

Iikhamera ze-CCTV zinokusebenzisa iintlobo ngeentlobo zeelensi ezixhomekeke kwisicelo sawo kunye nendawo yazo yombono. Nazi ezinye iintlobo zezilonda ezisetyenziswa kwiikhamera zeCCTV:

I-lens ehleliweyo: Ezi zenzo zinobude obusigxina kwaye azinakulungiswa. Zisetyenziselwa izicelo apho ibala lemibono alidingi kutshintshwa.

I-varifocal lensEzi lenses zivumela umsebenzisi ukuba ahlengahlengise ubude obujolise kuyo kwaye ngenxa yoko intsimi yembono. Ziluncedo xa ikhamera ifakwe kwindawo apho umgama phakathi kwekhamera kwaye isifundo sinokwahluka.

Zoom lens: Ezi zenzo zifana ne-darifocal lenses kodwa zibonelela ngeendlela ezibanzi zohlengahlengiso olujolise kuzo. Bavumela umsebenzisi ukuba asondeze okanye akhuphele kwisifundo ngaphandle kokuhambisa ikhamera.

I-pinhole lens: Ezi len zine-aperture encinci kakhulu, evumela ikhamera ukuba ifihlwe ngaphakathi kwento encinci okanye i-ball yedonga.

Ukukhethwa kweelensi kuxhomekeke kwiimfuno ezithile zesicelo, njengokuhamba kumxholo, iimeko zokukhanyisa, kunye nendawo oyifunayo.

二,WumnqwaziDoesI-CCTVCAmeraLi-isDo?

I-lens yenye yezona zinto zibalulekileyo zekhamera ye-CCTV, njengoko inoxanduva lokufaka kunye nokugxila kwi-South yekhamera. Ilensi ichaza intsimi yembono kunye nenani lokukhanya elingena kwikhamera, elinokuba nefuthe elibonakalayo kumgangatho kunye nokucaciswa komfanekiso okwiphepha.

Ilensi isebenza ngokugoba imitha yokukhanya edlula kuyo, ngoko ke bayiguqulela kwindawo ekugxilwe kuyo kwivaso yomfanekiso. Umgama ukusuka kwilensi kwi-insonsor yomfanekiso, kunye ne-curvature yelensi, ichaza ubude obujolise kwi-Intanethi kunye ne-engile yekhamera.

I-CCTV yekhamera ye-CCTV inokulungiswa okanye ihlengahlengiswe, kuxhomekeka kwiimfuno ezithile zesicelo. Iilensi ezizimiseleyo zinemigangatho yokugxila ejolise kuyo kunye nendawo yokujonga indawo, ngelixa i-lenses ehlengahlengiswayo, njenge-darifocal okanye iilensi ze-zoom, zinokulungiswa ukutshintsha ubude obujolise kwimbonakalo.

Kwisishwankathelo, i-CCTV yekhamera ye-CCTV idlala indima ebalulekileyo ekuthinteleni imifanekiso esemgangathweni kunye nevidiyo. Ngokulawula ubungakanani bokukhanya okungena kwikhamera kunye ne-engle yokujonga, iilensi zinceda ekuqinisekiseni ukuba ikhamera ithimba umxholo wesifundo kunye nokucaciswa.

Nangona kunjalo, i-aperture enkulu inokubangela ubunzulu bentsimi yentsimi, enokubangela izinto ngaphambili okanye kwimvelaphi yokuvela blurry.

Ukuhambelana: Qinisekisa ukuba iilensi ziyahambelana nemodeli yakho yekhamera kunye nosayino. Iikhamera ezahlukeneyo zinokuba neentlobo ezahlukeneyo zokukhwela, kwaye ayizizo zonke iilensi ziyahambelana nazo zonke iimodeli zekhamera.

Umgangatho womfanekiso: Khetha ilensi ngomgangatho womfanekiso olungileyo, oya kuqinisekisa ukuba ikhamera ithimba imifanekiso ecacileyo, eneenkcukacha.

Uhlahlo-lwabiwo mali: Ixabiso leIilebhu zekhamera yezokhuselekoUkuhluka ngokuxhomekeke kubude obugxile, i-aperture, kunye nomgangatho womfanekiso. Chonga uhlahlo-lwabiwo mali kwaye ukhethe ilensi ehlangabezana neemfuno zakho kwaye iwele kuhlahlo-lwabiwo mali lwakho.

Isishwankathelo, xa ukhetha ilensi yekhamera ye-CCTV, cinga ngobude obugxile, i-aperture, ukungqinelana, i-Microsoft ekumgangatho, kunye nohlahlo-lwabiwo mali lokuqinisekisa ukuba ufumana owona mgangatho ubalaseleyo wenkqubo yokhuseleko.
