Iilensi zeCCTVOko kukuthi, iilensi zekhamera zeCCTV, zineemeko ezininzi zokusetyenziswa namhlanje. Kunokuthiwa iikhamera zeCCTV ziyafuneka naphi na apho kukho abantu nezinto.
Ukongeza ekubeni sisixhobo solawulo lokhuseleko, iikhamera zeCCTV zikwasetyenziswa ekuthinteleni ulwaphulo-mthetho, ukuphendula ngexesha likaxakeka, ukubeka esweni okusingqongileyo kunye nezinye iinkqubo, kwaye indima yazo ayinakujongelwa phantsi.
1.Ndingenza njaniI-CCTViilensi ziyasebenza?
Kwiilensi zeCCTV, singajonga indlela esebenza ngayo:
(1)Ukuthwebula imifanekiso
Ikhamera yeCCTV ithatha imifanekiso yendawo ekujoliswe kuyo ngokusebenzisa izinzwa zemifanekiso ize iziguqule zibe ziimpawu zombane.
(2)Ukucutshungulwa kwemifanekiso
Isignali yomfanekiso idluliselwa kwiprosesa yomfanekiso yangaphakathi, ethi emva koko yenze uhlengahlengiso oluzenzekelayo lokuvezwa, ukulungiswa kwebhalansi emhlophe, ukucoca ingxolo kunye neminye imisebenzi yokuphucula umgangatho womfanekiso.

(3)Ukuhanjiswa kwedatha
Idatha yomfanekiso ecutshungulwayo idluliselwa kwisixhobo sokugcina okanye kwinkqubo yokubeka esweni nge-interface yokudlulisa idatha (njengenethiwekhi okanye umgca wedatha). Ukudluliselwa kwedatha kunokuba ngexesha langempela okanye kungengokwangoku.
(4)Ukugcinwa kwedatha kunye nolawulo
Idatha yemifanekiso igcinwa kwi-hard drive yenkqubo yokujonga, kwisitoreji sefu, okanye kwezinye izinto ezisetyenziswayo ukuze idlalwe, ifunyanwe, kwaye ihlalutywe. Inkqubo yokujonga idla ngokubonelela ngojongano olubonakalayo kubasebenzisi ukuze balawule kwaye bafikelele kwidatha egciniweyo.

2.Imibuzo emininzi eqhelekileyo malungaI-CCTViilensi
(1)Indlela yokukhetha ubude be-focal yeI-CCTVilensi?
Xa ukhetha ubude be-focal lens ye-CCTV, landela le migaqo ilandelayo:
①Linganisa ubude bento ejongwayo ngokusekwe kubukhulu kunye nomgama wento ejongwayo.
②Ngokwenqanaba leenkcukacha ofuna ukuzijonga: ukuba ufuna ukubona iinkcukacha zento ejongiweyo, kufuneka ukhethe ilensi enobude obude bokugxila; ukuba ufuna ukubona imeko iyonke, khetha ilensi enobude obufutshane bokugxila.
③Cinga ngemida yendawo yokufaka: Ukuba indawo yokufaka ilensi incinci, ubude befocal akufuneki bube bude kakhulu, kungenjalo umfanekiso uya kuba mfutshane kakhulu.
Iilensi zeCCTV ezahlukeneyo
(2) Ingaba kungcono ukuba uluhlu oluphambili lwelensi yeCCTV lukhulu?
Ukukhetha ubude be-focalIlensi yeCCTVkufuneka kumiselwe ngokweemfuno zokujonga. Ngokubanzi, ilensi enobude obude bokugxila ingagubungela umgama omde, kodwa ikwathetha ukuba i-engile yokujonga yomfanekiso incinci; ngelixa ilensi enobude obufutshane bokugxila ine-engile yokujonga ebanzi, kodwa ayinakubona iinkcukacha ezikude.
Ngoko ke, xa ukhetha ubude be-focal lens, kuyimfuneko ukukhetha ngokwemeko yokujonga kunye neenjongo ekufuneka zifezekiswe. Akunyanzelekanga ukuba kubekho ubude be-focal obukhulu, kokukhona bungcono.
(3) Yintoni omawuyenze ukuba ilensi yeCCTV ayicacanga?
Ukuba ilensi yeCCTV ifunyaniswe ingacacanga, kukho izisombululo ezininzi ezinokubakho:
①Lungisa ingqwalasela
Umfanekiso usenokuba mfiliba ngenxa yokugxila kwelensi okungafanelekanga. Ukulungisa ukugxila kungenza umfanekiso ucace.
②Coca ilensi
Ilensi isenokuba luzizi ngenxa yothuli okanye ezinye izinto. Ngeli xesha, sebenzisa izixhobo ezifanelekileyo zokucoca ukuze ucoce ilensi.
③CHayi bo, iswitshi yezinto zakudala
Ukuba ilensi isabonakala ingacacanga, ungajonga iswitshi yelensi ukuze ubone ukuba ivuliwe na.
④Buyisela ilensi
Ukuba ezi ndlela zingasentla azinakuyilungisa ingxaki, kusenokwenzeka ukuba ilensi iyaluphala okanye yonakele, kwaye kufuneka itshintshwe ilensi entsha.

(4) Yintoni ebangela ilensi yeCCTV engacacanga?
Izizathu eziphambili zokungacaciIilensi zeCCTVisenokuba: ukungcola kumphezulu welensi, ukufuma komphunga wamanzi, ukungcangcazela okanye impembelelo kwilensi ebangela iingxaki zokugxila, ukufiphala ngaphakathi kwekhamera okanye kwiingxaki zemodyuli, njl.
(5)Ungasusa njani uthuli kwilensi yeCCTV?
①Ungasebenzisa i-blower okanye ezinye izixhobo ezifanayo ukuvuthuza uthuli olukumphezulu welensi.
②Ungasebenzisa iphepha lokucoca ilensi elikumgangatho ophezulu okanye ilaphu elikhethekileyo lokucoca ilensi ukucoca ilensi.
③Ungasebenzisa nolwelo olukhethekileyo lokucoca ilensi xa ucoca, kodwa khumbula ukulandela indlela emiselweyo ukuze ungonakalisi ilensi.
Iingcinga Zokugqibela:
Ukuba unomdla wokuthenga iintlobo ngeentlobo zeelensi zokujonga, ukuskena, iidrone, ikhaya elikrelekrele, okanye naluphi na olunye uhlobo lokusetyenziswa, sinazo izinto ozifunayo. Nxibelelana nathi namhlanje ukuze ufunde okungakumbi ngeelensi zethu kunye nezinye izixhobo.
